Underdog Promo Code SICOM: 50% Match Up to $1,000 (August 2026)

The latest Underdog promo code gives new users a 50% deposit match up to $1,000 in bonus funds, one of the largest welcome offers available. Underdog now combines sports prediction markets with fantasy picks and drafts, covering the NFL, NBA, MLB, and more.

I've claimed and tested the Underdog $1,000 bonus firsthand and can verify how it works. I'll explain how you can claim the offer in minutes and use Underdog Predictions and its other sports products today.

The best Underdog promo code is SICOM, which lets eligible new users choose between two top prediction market promos, including a 50% first-deposit bonus where you can get up to $1,000 matched.

Here are the key Underdog promo code details, including the bonus, deposit requirements, eligible products, and availability.

The Underdog promo code SICOM gives new users a 50% first-deposit match up to $1,000 in bonus funds. The bonus can be used across eligible Underdog products, including Underdog Predict, Pick'em, Best Ball, and drafts. 

I've played across Underdog's different game formats, and the ability to use the bonus throughout the platform is one of its biggest advantages. If you only want to speculate via Underdog Predict, you can use the new bonus entirely on NFL, MLB, NBA, and other sports trades. However, if you enjoy Pick'em or Underdog's fantasy games, such as best ball, you can also use your bonus funds on those classics.

For this review, I'll focus primarily on Underdog Predict and using bonus funds on sports event contracts.

✍️ How to claim the Underdog $1,000 bonus

Claiming the Underdog $1,000 bonus takes just a few steps:

1. Create a new Underdog account using promo code SICOM.
2. Make a first deposit of at least $10.
3. Receive a 50% match on your qualifying deposit.
4. Deposit $2,000 to receive the maximum $1,000 in bonus funds.
5. Use your bonus funds on Underdog Predict or other eligible Underdog products.

I've found Underdog Predict easy to navigate and rate it as one of our top prediction market apps for new users, especially if you're already familiar with Underdog Pick'em, a game with principles similar to prediction trading. New Underdog users can immediately use the bonus funds on event contracts covering the NFL, NBA, MLB, and other major sports.

The Underdog 50% deposit match is credited as promotional bonus funds and can be used across eligible Underdog products, including Underdog Predict. I've found the offer fairly flexible, but there are a few important rules to understand before deciding how much to deposit.

• 50% match up to $1,000: Underdog matches half of your qualifying first deposit. You need to deposit $2,000 to receive the maximum $1,000 bonus.
• 1x playthrough: The requirement applies to your deposit and bonus combined. For example, a $100 deposit earns a $50 match, creating $150 in required qualifying playthrough.
• 14-day deadline: You have 14 days to complete the playthrough. Any promotional balance that hasn't qualified by the deadline can be forfeited.
• Underdog Predict eligible: You can use the bonus on eligible Underdog Predict markets as well as qualifying fantasy products available in your state.
• Bonus isn't immediately withdrawable: Promotional funds remain subject to the playthrough requirement rather than functioning like unrestricted cash.
• Winnings can be withdrawn: Eligible winnings generated while completing the playthrough can be withdrawn before you've finished the entire requirement.
• Your deposit isn't forfeited after 14 days: Failing to finish the requirement can cost you the remaining promotional balance, rather than automatically wiping out your original cash deposit.
• Keep Your Million is an alternative: New users can choose Keep Your Million instead of the 50% deposit match. Selecting another welcome offer at sign-up means you won't have access to Keep Your Million.

The Underdog promo code SICOM matches 50% of your first deposit, up to $1,000 in bonus funds. 

The key point is that the 1x playthrough requirement applies to your deposit and bonus combined, and you have 14 days to complete it.

Underdog deposit match and playthrough examples

For example, if I deposit $100, Underdog adds a $50 bonus. That gives me $150 for playthrough purposes, meaning I need to generate $150 in qualifying entry fees within 14 days.

You don't need to deposit the full amount to receive a bonus, but the amount of your deposit bonus does determine the amount of bonus you receive. 

What happens if I don't complete the playthrough in 14 days?

If you don't meet the requirement within 14 days, Underdog can forfeit your remaining promotional bonus. The requirement doesn't mean your original deposit simply disappears after 14 days; it applies to qualifying the promotional balance.

A few details are especially useful to know:

• Winnings can be withdrawn: Winnings generated during the playthrough period may be withdrawn before the entire requirement is completed.
• Bonus funds aren't immediately cash: The promotional balance remains subject to the offer's playthrough rules.
• You can opt out: You can contact Underdog support to cancel your participation if you don't plan to complete the requirement, but you'll forfeit the bonus.
• Watch the 14-day deadline: I recommend tracking your remaining qualifying volume, particularly if you claim a larger match.

Example:

I deposit $2,000 on Underdog and earn $1,000 in bonus funds from the 50% deposit bonus, creating a $3,000 playthrough requirement.

Over my first 14 days playing on Underdog and Underdog Predict, I used $500 of the bonus funds on trades or entries and made $500 in profit (cash). The extra $500 in profit (cash) I have earned is now available to withdraw. 

However, the remaining $500 in bonus funds is not withdrawable, and I have only seven days left in my original 14-day timeframe to complete my playthrough requirement and use them before they expire.

My take on the Underdog $1,000 bonus after using it

After claiming and clearing the Underdog $1,000 bonus myself, it's evident that the 50% deposit match offers excellent value, but it's equally evident that not all users should deposit $2,000 just because that's what unlocks the maximum bonus.

I deposited the full $2,000 and received the $1,000 match. I cleared the required playthrough by using Underdog every day and spreading my activity across multiple products, including Underdog Predict, best ball entries, and Pick'em. That's realistic for an active Underdog user, but it creates a substantial $3,000 playthrough requirement that must be completed within 14 days.

For someone new to Underdog, I'd start with an amount that matches how much you actually expect to play:

• Occasional user: A smaller deposit makes the 14-day requirement much easier and less stressful to manage.
• Regular sports fan: Deposit based on your normal activity rather than chasing the $1,000 maximum.
• High-volume user: The full $2,000 deposit can make sense if you're confident you'll naturally clear $3,000 in qualifying play.

The 50% match scales with your deposit, so there's no need to maximize it to get value. In my experience, the $1,000 bonus is achievable, but I'd rather leave some bonus on the table than deposit or play more than I'm comfortable with just to clear a promotion.

Bottom line: Only deposit and play with money you can afford to lose. Don't increase your spending simply to maximize the bonus or complete the playthrough requirement.

I claimed the Underdog promo code SICOM with a $2,000 deposit, which unlocked the maximum $1,000 bonus. You don't need to deposit that much—the 50% match scales with your first deposit, so choose an amount you're comfortable playing through.

Here's how I claimed and used the offer on Underdog, and how I used my bonus across Underdog Predict and the rest of the platform.

1. Sign up for Underdog

Open Underdog through one of the links on this page and create a new account. Enter the Underdog promo code SICOM during registration and complete the required identity verification.

2. Deposit and get a 50% match

Make a first deposit of at least $10. Underdog matches 50% of your deposit in bonus funds, up to $1,000.

I deposited $2,000 and received the full $1,000 match, giving me a playthrough requirement of $3,000. You can deposit less and receive the same 50% match at a more manageable level: for example, a $500 deposit would get you a $250 bonus with a $750 playthrough requirement.

I used online banking for my deposit, which is a good option if you plan to use the bonus on Underdog Predict. Underdog also accepts credit/debit cards, Apple Pay, Google Pay, PayPal, and Venmo, although PayPal and Venmo deposits currently can't be used for prediction-market entries.

3. Use your bonus on Underdog Predict

Once credited, you can put your bonus funds to work across eligible Underdog products. I spread mine across several game types, including Underdog Predict, rather than trying to complete the requirement in one place.

Underdog Predict lets you trade sports event contracts covering the NFL, NBA, MLB and more, making it one of the most relevant ways to use the new offer.

4. Complete the playthrough and withdraw

You have 14 days to complete 1x playthrough of your deposit and bonus combined. In my case, that meant $3,000 in qualifying volume.

I cleared the requirement by playing regularly across multiple Underdog products. Once you're ready to withdraw eligible funds, available methods include:

• Visa/Mastercard debit card
• Trustly / online banking
• PayPal
• Venmo

My advice: Don't deposit $2,000 solely to chase the maximum $1,000 bonus. Pick a deposit amount that gives you a playthrough requirement you can comfortably complete within 14 days.

The Underdog promo code SICOM stands out from most prediction market offers because its 50% deposit match can reach $1,000 in bonus funds. That's a much higher maximum than the fixed welcome bonuses offered by most competitors, although Underdog's 1x playthrough requirement means you should consider how much you realistically plan to trade or play before choosing your deposit.

Here's how Underdog compares with other prediction market promos I've tested for August 2026.

Underdog promo code vs. Polymarket promo code

The Polymarket promo code is a better fit if you prioritize market depth and want to trade exclusively on prediction markets. Polymarket offers a simple and easy-to-claim deposit match and a much larger selection of sports, politics, economics, and other real-world events.

Overall, Underdog has the clear edge and offers strong product flexibility. Its deposit match can reach $1,000, and you can use the promotional funds across Underdog Predict and its other eligible sports products.

Underdog promo code vs. Kalshi promo code

Kalshi remains one of my preferred pure prediction market platforms, with extensive sports and non-sports markets and a trading-focused interface. Its welcome offer is also easier to maximize with the Kalshi promo code because it requires considerably less upfront money.

The Underdog promo code has much more upside if bonus size is your priority, but you'll need to deposit and complete more qualifying volume. Overall, the choice is between getting more value on your bonus for sports and fantasy contests or accessing one of the best overall prediction markets for sports and real-world trading on Kalshi.

Underdog promo code vs. OG.com promo code

OG.com is another sports-focused alternative, particularly if you want a prediction market platform built primarily around sports trading and social features.

Underdog offers a broader overall sports experience. I've been able to move between Underdog Predict, Pick'em, and drafts while using the 50% deposit match, which gives me much more potential promotional value than the OG promo code welcome offer.

Underdog promo code vs. ProphetX promo code

The ProphetX promo code is worth considering if you primarily want to trade sports. Its exchange-style platform, sports market selection, and 0% fees on profitable parlays make it a more specialized alternative to Underdog.

The biggest difference is the welcome bonus: ProphetX offers a smaller fixed reward with a low qualifying threshold, while Underdog lets you scale your 50% match up to $1,000.

Underdog promo code vs. Novig promo code

Novig also focuses heavily on sports and has a lower barrier to unlocking its welcome bonus through the Novig promo code. That makes it appealing if you want to test a prediction platform without committing much money upfront.

I'd favor Underdog for higher bonus potential and variety. The ability to use the promotion across Underdog Predict and other eligible products gives you more ways to clear the offer, especially if you're already an active Underdog user.

Underdog vs. prediction market referral bonuses

If you want to make money by inviting friends to the site you trade on, you'll want to learn more about the Kalshi referral code, the Polymarket referral code, and the Crypto.com referral code. All three can set you up for big rewards when you share your unique links with friends.

Keep Your Million is the alternative welcome offer to Underdog's 50% deposit match up to $1,000.

• Option 1 — Deposit match: 50% first-deposit match up to $1,000.
• Option 2 — Keep Your Million: Deposit at least $10 to unlock the game, then attempt to preserve as much of the virtual $1 million as possible through the 20 questions. Whatever survives is paid as bonus funds.

Both offers can be activated when you use promo code SICOM, but you can only choose one. If you choose Keep Your Million, instead of receiving a guaranteed match based on your first deposit, you start with 1 million virtual Milly Bucks and try to preserve as much of that balance as possible through 20 player-pick questions.

Whatever you have left after completing all 20 questions converts into Underdog bonus entries, up to a potential $1 million.

How does Underdog Keep Your Million work?

The concept is simple: each round gives you a Higher/Lower player pick and you decide how much of your remaining Milly Bucks to allocate to each outcome.

1. Start with 1 million Milly Bucks: Every participant begins with the same virtual balance.
2. Make a Higher/Lower decision: Underdog presents a player pick with two possible outcomes.
3. Divide your balance: Put as much or as little as you want on either side. You can even split your balance between the two.
4. Lose the incorrect allocation: Only the Milly Bucks assigned to the winning outcome advance.
5. Repeat for 20 questions: Your surviving balance carries into each new round.
6. Convert your final balance: Complete all 20 questions, and your remaining Milly Bucks will convert into bonus entries.

If you select Keep Your Million, you have seven days after signing up to make the minimum $10 deposit and unlock it. Once the game starts, you then have 60 days to finish it.

If your balance reaches zero at any point, you're eliminated and don't receive a Keep Your Million prize. 

Keep Your Million example

Say I have $500,000 in Milly Bucks remaining when I'm asked whether an NFL quarterback will throw Higher or Lower than 275.5 passing yards.

I could put $350,000 on Higher and $150,000 on Lower. If Higher hits, I advance with $350,000. If Lower hits, I survive with $150,000.

That's what makes Keep Your Million different from simply picking 20 winners. You control how much of your balance you're willing to risk on each answer. Going heavily toward one side preserves more money when you're right but costs you more when you're wrong.

You can preserve your bonus longer with more balanced picks, but with 20 picks needed, you're going to have to take some risks if you want to leave with any kind of substantial sum.

Keep Your Million rules at a glance

• Starting balance: 1 million Milly Bucks
• Maximum questions: 20
• Time limit: 60 days
• Maximum reward: $1 million in bonus entries
• Cash value of Milly Bucks: $0
• Zero balance: Eliminates you from the promotion
• Final balance: Converts to bonus entries after successfully completing the promotion
• Bonus playthrough: 1x
• Selections: Lock when submitted and can't be canceled
• Welcome offer: Choose Keep Your Million contest or the guaranteed 50% deposit match up to $1,000

Remember that $1 million is the maximum possible bonus-entry value, not a $1 million cash prize. Your actual reward will be distributed as bonus credits and will depend on how much of your starting Milly Bucks you preserve through all 20 questions.

Should I choose Keep Your Million or the $1,000 Underdog bonus?

For most new users, I'd choose the 50% deposit match if predictable bonus value is the priority. You know exactly how much you'll receive based on your deposit, and there's no risk of losing the promotional opportunity because a series of picks goes against you.

Keep Your Million has a very different appeal. One of the best things about choosing the contest over the deposit bonus is that you don't need to deposit $2,000 or meet the $3,000 qualifying volume to maximize the $1,000 match. However, if you choose to keep your million, you'll be trading certainty (in the form of the deposit bonus) for a game with far greater potential upside, but far more downside as well (as you could leave with nothing).

Having played Underdog's Higher/Lower formats myself, I also think Keep Your Million is the more entertaining choice. Deciding how aggressively to split your balance over 20 questions adds a strategy element that a straightforward deposit match doesn't have.

My take: Take the $1,000 deposit match if you want predictable promotional value and already expect to play enough to clear it. Consider Keep Your Million if you don't want to commit that much money upfront, enjoy Underdog's player-pick games, and are willing to trade a guaranteed deposit match for a shot at a substantially larger bonus.

Predictions markets are exploding across the U.S., with platforms like Kalshi and Polymarket now considered top-rated and wildly popular speculating sites. Underdog has also entered the prediction space with the launch of Underdog Predict in 2025, which is available on the Underdog app across most of the U.S. 

What is Underdog Predict?

Underdog Predict is a new trading platform and a federally regulated feature within the main Underdog Sports app that allows users to trade 'Yes' or 'No' contracts on team and player outcomes in sports, as well as other real-world events. With predictions, all prices are dynamic and update in real-time as trading occurs. 

Key features on Underdog Predicts

Real-time trading: Prices per contract range between $0.01 and $1.00 with no set price as you'd see on standard sportsbook odds. 

Wide range of sports to trade: Options to trade on include major sports, leagues, and non-sports markets such as entertainment award shows, such as: Football, Basketball, Baseball, Hockey, Tennis, college football, Soccer, Weather, Politics, and Economics. 

Easily accessible: Underdog Predict is available within the Underdog Sports app, so you can rotate between games and move your bankroll around with ease.

How to trade on Underdog Predict

Accessing Underdog Predict is simple. As an existing Underdog user in a supported region, you'll have immediate access to Underdog Predict on the Underdog app. 

Once you've downloaded and signed up with Underdog, just follow these steps to start trading. 

1. Open the Underdog app and go the Underdog home screen. 
2. Look for the 'Team Picks' tab. This is where you'll find Underdog Predict and begin trading.
3. Once in Predictions, select a game to view all of the outcomes available to trade on for that event.
4. Select a trade, set the number of contracts you wish to purchase, and then lock in your trade.

Remember that sports betting and prediction markets are not the same thing. Make sure to read our prediction markets vs. sports betting guide for a deeper look at the differences between the two.  

Key terms for Underdog Predict

Event contract: A tradable contract priced from $0.01 to $1, representing either a "yes" or "no" position on a specific event, such as whether a team wins or a player hits a certain stat.

Prediction picks: The main feature allows users to predict outcomes — such as game winners, point spreads, and totals — instead of drafting players, typically for sports like the NFL, MLB, and UFC.

Probability-based pricing: Before an outcome settles, contracts are priced between $0.01 and $0.99 based on the market's implied probability rather than traditional odds. For example, a 65% chance to win results in a price of $0.65 for a "Yes" contract.

Payout/settlement: Correct predictions pay out exactly $1.00 per contract, while incorrect predictions return nothing. For example, buying 10 contracts and having your outcome settle correctly would see a $10 total payout.

Parlay: Parlays on Underdog Predicts are user-requested trades that combine multiple specified events. You can create "parlays" for predictions by combining up to 4 prediction picks into a single entry.

Combo entries: You can also create prediction market combos that combine 1 Prediction Pick with 2 to 8 additional Fantasy picks. 

Game-Level outcomes: These trades are similar to moneylines, spreads, or game totals on sportsbooks. They involve trading a team-specific outcome.

Individual player markets: Contracts based on specific player statistics, such as touchdowns, passing yards, or rushing yards. Similar top player props on sportsbooks.

Exchange/CDNA: The underlying, regulated exchange (Crypto.com | Derivatives North America) that handles the trading and settlement of the contracts.

Cash out: The ability to settle a contract early before the event is finished. Underdog Predicts allows traders to settle a trade at any time before settlement, provided there is sufficient liquidity.

Does Underdog Predict have a welcome bonus?

Yes, new users can now claim the Underdog promo code SICOM and use the welcome bonus with Underdog Predict, rather than the promotion being limited to Underdog's fantasy products.

The current offer provides a 50% first-deposit match up to $1,000 in bonus funds. Once credited, you can use the bonus on eligible Underdog products, including prediction markets, to trade sports event contracts while working toward the promotion's playthrough requirement on one of the top NFL prediction market apps.

This makes the new offer considerably more relevant for prediction-market users: you can now claim one Underdog welcome bonus and put the promotional funds to work directly on Underdog Predict.

Underdog Predict markets

Underdog Predict is a new platform, but it already offers a strong selection of markets for traders, with a heavy sports emphasis. I created a current list for all major sports and leagues that Underdog Predict covers, as well as non-sports options such as elections and awards shows:

• Football (NFL)
• Basketball (NBA)
• Baseball (MLB)
• Hockey (NHL)
• Tennis
• College football
• Soccer
• Weather
• Oscars
• Grammys
• Politics
• Economy and business

Where is Underdog Predict available?

Underdog Predict is currently available in 39 states plus Washington, DC. Users must be 18+ and physically located in an eligible state when trading Prediction Picks.

One quick note for new users: eligibility depends on where you are physically located, not your state of residence.

Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, and Washington are also notable because Underdog Predict is available there, even though Underdog Pick'em and Drafts are not.

If you're big into predictions and want to try an alternative to Underdog Predict or access another platform where you can hedge trades or look for alternative prediction markets, I've laid out your best options. 

Want additional details about an Underdog alternative? Read our Kalshi review for a comprehensive overview of this prominent sports-event trading platform, or explore our Polymarket review for insights into one of the world's largest real-world prediction markets.

I've played and tested most fantasy games on the Underdog Fantasy app, including a few of its massive season-long NFL best-ball contests. I'll share my thoughts on why it's such a great option for anyone looking to get started with season-long and daily fantasy draft games, or use it for single-user daily fantasy Pick'em contests. 

What is Underdog Fantasy?

Underdog Fantasy is a true all-in-one destination for anyone interested in competing in daily and season-long fantasy games across major sports leagues. The app has draft-friendly options for season-long and daily fantasy contests, along with single-user daily fantasy Pick'em games available almost nonstop. 

Key features

What I like most about Underdog Fantasy is that almost every time I open the app, I can invest in short- or long-term fantasy games. Season-long best ball contests run year-round, and Underdog's massive NFL Best Ball Mania VII contest is set to award $2M to first place this season. 

My list of favorite features on Underdog Fantasy include: 

• Season-long NFL ball contests with entries from $5 up to $500.
• Massive prize pools for those interested in large, multiple-entry contests.
• In-app and on-site fantasy rankings with up to date player ADPs
• Daily draft contests for all major sports (NFL, PGA, NHL) for those who love drafting over the traditional salary cap format on most DFS sites.
• Expansive Pick'em contests that covers all major sports and niche markets such as golf, esports, WNBA, League of Legends (LoL), and more.
• Consistent array of profit boosts and reward tokens for Pick'em lineups.
• Live tracking feature where you can track Pick'em lineups and Draft entries.

Underdog Fantasy pros and cons

✅ Pros (what works)

• Best Ball leadership: It hosts some of the largest fantasy tournaments globally, such as the $15 million Best Ball Mania.
• High payout multipliers and boosts: Underdog often provides better odds than competitors for Pick'em games and regular boost offers.
• User experience: One of the highest App Store ratings (4.8/5) among fantasy operators. Noted for its modern design and intuitive navigation.
• Contest formats: Unique games like 'Rivals' (picking between two players with a spread) and 'Battle Royale'.
• Transparent "Rake": Underdog is known for displaying the site fee (rake) for its fantasy contests, helping serious players calculate the cost of entry.

⚠️ Cons (what doesn’t)

• Slow withdrawal processing: Several methods, such as PayPal and Venmo, may require verification emails, which can slow withdrawals.
• Aggressive account limiting: Accounts can be limited after significant wins in Pick'em, often cited as "Terms of Service" violations, with no specific details provided.
• Limited customer support: No phone number for support. Users must rely on live chat or email, which have limited authority to resolve complex disputes.

The Underdog Sports app has always been a mainstay for me. Even after taking a break from the season-long grind of NFL fantasy games, I'd still use the app for Pick'em lineups almost daily, or even enter the odd daily draft just because the draft process is so easy on mobile. 

Underdog has done well in expanding their market coverage, now offering regular live Pick'em markets for all major sports.

My top features of the Underdog Sports app include:

• Lightning fast draft response where quick decisions are needed.
• Clear multipliers that make Pick'em payouts easy to track.
• Excellent contest tracking in the live section so I always know the status of my lineups.
• Some of the largest best ball contests available for NFL and NBA season-long.
• Consistent boost offerings that make games more profitable.

🍎 Underdog iOS app

Underdog Sports has one of the highest-rated daily fantasy apps in the industry. It's currently holding a 4.8/5 rating on the App Store, based on over 310,000 reviews.

🤖 Underdog Android app

The Underdog Sports app has a strong rating in the Google Play Store as well. With 31,000 ratings, it's maintained a strong 4.6/5 rating. 

🐕‍🦺 Underdog customer support

Underdog claims to provide 24/7 customer support; however, the support is limited to one or two options, neither of which is by phone. 

The live chat icon at the bottom of the page will connect you with a support agent. However, you'll need to go through an AI screening process for your issue before connecting, which can be time-consuming. You can also send an email, but I've found responses can take anywhere from a few hours to over a day. 

• Live chat: Yes
• Email: support@underdog.com
• Phone: N/A
• X (Twitter): @UDSupport

✍ SI Expert analysis: I found Underdog support great for resolving small issues, usually a withdrawal that was 'stuck' or taking longer than normal. However, with larger problems that involved contest entry issues or payouts often they were far less helpful. This is an area I'd like to see them take more seriously in the future.  

As a top social platform for fantasy, drafting, Pick'em, and predictions, Underdog shines with a consistent offering of existing user bonuses. 

I received profit boosts for Pick'em lineups on a near-daily basis, along with reload bonuses for the entire site at critical times of the year (start of NFL and playoffs).

I went through and explained all of the best Underdog current user promos, so you'll know what to expect when you sign up:

Signing up with the Underdog Sports app will allow you access to a huge variety of fantasy contests and prediction markets.

I outlined my favorite contests and markets so you can see why Underdog Sports has become the go-to mobile spot for anyone looking to access daily fantasy drafts and contests, Pick'em, and predictions on one app. 

▶️ Pick'em contests

Pick'em contests require you to build an entry with 2 to 8 players' stats, predicting whether each player's total you choose will be "Higher" or "Lower" than the projected line. These are similar to how you would build a parlay on traditional sportsbooks.

• Standard picks: The classic Higher/Lower format, where you choose a side on individual player stats like points, rebounds, or touchdowns.
• Rivals: Head-to-head player matchups where you pick which of two players will outperform the other in a specific stat. These often include a "handicap" (e.g., Player A +5.5 points vs. Player B) to balance the matchup.
• Scorchers: Higher-payout picks where you choose players to exceed a significantly higher-than-average stat line (e.g., a player to score 40+ points instead of their standard 25.5).
• Ladders: Entries where your payout increases with each "rung" or pick you get correct.
• Champions: Peer-to-peer contest where you can select up to 8 player stats to win up to 500x your money.
• Streaks: A mode where you try to win consecutive picks to reach a grand prize of up to 1,000x your money, with a "Cash Out" option available.

✍ SI Expert analysis: Underdog is great at providing Pick'em promos for its current users, including daily boosts for specific sports. Use them to try out a new sport, as the increased payout will make the transition into a new market a little easier. 

📝 Draft-Style contests

Underdog's reputation was built on the back of its huge offering of snake-draft formats, where you compete against other users in a single draft room. You'll find these contests still available on the site in several different formats.

• Best Ball: Season-long or tournament-style drafts where you do not need to manage your lineup. Underdog automatically starts your highest-scoring players each week.
• Best Ball Mania (BBM): Large-scale NFL tournaments (e.g., $15M prize pool) with multiple advancement rounds leading to a Week 17 final. Best Ball Mania VII is now available with a $2M first prize.
• The Big Board/Bigger Board: Pre-draft NFL contests where you draft players before the actual NFL draft occurs.
• Daily Drafts: Fast-paced snake drafts for a single night's slate of games.
• Battle Royale: A hybrid format that combines a 6-round snake draft with DFS-style tournament scoring for a single week or day.
• The Eliminator: A survival-style draft tournament where the lowest-scoring teams in a group are eliminated each week until a winner is crowned.
• The Scramble: A golf-specific best ball format (e.g., PGA Scramble) where rosters are built through a snake draft for multi-event tournaments.

✍ SI Expert analysis: Underdog uses 0.5 PPR scoring in NFL which can have a dramatic effect on player values for WRs and RBs. Ensure you go over all the terms and have a good look at ADP rankings before entering. 

🔮 Prediction markets

Underdog Predict offers trading markets across almost all major sports, including the NFL, NBA, MLB, NHL, PGA, Soccer, and College Sports. These offerings include regular game markets and player stats. 

• Team outcomes for predictions:
• Moneylines: Buying contracts on a team to win a specific game outright.
• Spreads: Trading on whether a team will cover a specific point, run, or puck line (e.g., "Panthers +3.5").
• Game totals: Predicting if the combined score of a game will be Higher or Lower than a set number.
• Player performance markets for predictions:
• Contracts based on individual player stats, such as a quarterback's passing yards or a player scoring a touchdown.

Underdog operates as a legal daily fantasy sports (DFS) and regulated derivatives platform in over 40 U.S. states. Availability is divided into three distinct product tiers based on local state regulations.

Pick’em and predictions: Active in 30+ states, including high-traffic areas for users who are looking for alternatives to California sports betting, Florida sports betting, Georgia sports betting, and Texas sports betting.

Pick'em Champions: In states like Florida, Alabama, and Arizona, you can compete in Pick'em but only against other users in a peer-to-peer format to satisfy local skill-game laws.

Best ball and daily drafts: Widely available across the U.S. and Canada (excluding Ontario). In states like New York, Maryland, and Ohio, traditional Pick'em is restricted, but you can still enter real-money season-long or daily drafts.

August 2026: Underdog introduced a new welcome offer providing a 50% first-deposit match up to $1,000 in bonus funds. New users can also choose Keep Your Million as an alternative welcome offer, which starts players with a virtual $1 million to work through a series of player-pick questions.
