OG Promo Code SIBONUS October 2026: Trade $10, Get $10 Bonus

The latest OG promo code SIBONUS lets new users claim a $10 bonus when they trade $10 on OG Prediction Markets. Enter the OG.com promo code SIBONUS when signing up, complete $10 in qualifying trades, and receive the $10 welcome bonus.

OG.com offers prediction markets for NFL Week 5 and other sports, plus politics, finance, crypto, and culture. I’ve claimed and tested the OG $10 welcome bonus and will show you how the offer works and the key promo terms you need to know.

One advantage of the current OG welcome offer is its low $10 qualifying requirement. New users only need to complete one eligible $10+ settled trade to earn the $10 bonus, worth 100% of the minimum qualifying trade amount. This makes SIBONUS a relatively straightforward prediction market welcome offer to unlock, with solid value for new traders.

The table below breaks down the qualifying trade rules, eligibility and state restrictions.

Use any of our verified OG.com links to sign up and enter OG promo code SIBONUS to activate the current new-user offer. SIBONUS is the newest OG promo code available through SI and gives eligible new users a $10 bonus after completing the small qualifying trade requirements.

After you register and verify your account, you have seven days to complete a qualifying $10+ trade. The trade must be placed on an outcome priced below 80% probability and settle within the seven-day qualification window.

Once it settles and the promotion requirements are met, you'll receive $10 in OG trading credits.

OG prediction promo: Trade $10, get a $10 bonus

The best OG promo code available is SIBONUS, as it offers a $10 bonus for completing a small qualifying trade of $10. That means the bonus is worth 100% of the minimum qualifying trade amount, although the maximum bonus remains $10.

One important restriction to know before placing your first trade: your initial qualifying trade must be on an outcome priced below 80% probability when you enter the position. A heavily favored outcome at 80% probability or higher will not qualify.

Here's how that works:

✅ Qualifying trade: Trade $10 on the Seattle Seahawks to beat the New England Patriots at 63% probability.

❌ Non-qualifying trade: Trade $10 on the Los Angeles Rams to beat the Atlanta Falcons at an 81% probability.

In other words, don't simply choose the biggest favorite available to complete the promotion. Check the contract probability before making your first trade, and make sure it is below 80%.

OG bonus at a glance: Sign up with SIBONUS → verify your account → complete a $10+ qualifying trade below 80% probability within seven days → let the trade settle → receive $10 in OG trading credits.

I claimed the OG promo code SIBONUS $10 bonus by signing up through one of our verified links and completing a qualifying $10+ trade. I funded my account with a debit card, although OG.com supports several deposit methods, including cryptocurrency funding through its Crypto.com integration.

To qualify for the OG $10 bonus, use the OG promo code SIBONUS and complete one eligible $10+ trade. Your qualifying trade must be placed on a market priced below 80% probability and settle within seven days of KYC approval. Once you meet those requirements, you'll receive the $10 OG welcome bonus.

When I claimed the OG promo code, I deposited more than the minimum so I could also test other OG prediction markets, including politics, and try its Combo trades.

For my qualifying trade, I put $10 on an MLB game outcome trading at 64% probability. The trade met OG's under-80% requirement, and my $10 bonus was credited after the market settled.

The OG promo code SIBONUS for new users is easy to claim and offers a low-risk way to explore different prediction markets. Before getting started, review the key OG.com promo terms and conditions below to make sure you qualify for the $10 bonus:

OG Promo Code SIBONUS: Trade $10, Get $10

• Eligible states: The OG promo code SIBONUS is available to new users in all eligible U.S. states except Arizona (AZ).
• Sports market restrictions: New users in Illinois (IL), Massachusetts (MA), Maryland (MD), Michigan (MI), New Jersey (NJ), Nevada (NV), and Ohio (OH) can still claim the OG promo code SIBONUS, but cannot use sports contracts to qualify. Users in these states must complete the $10 qualifying trade on an eligible non-sports prediction market, such as politics, finance, crypto, or culture.
• Location requirement: You must be physically located in a state where OG is legally available when claiming the promotion.
• Minimum qualifying trade: Place and settle an initial trade of at least $10 to qualify for the $10 OG promo bonus.
• Probability requirement: Your initial $10+ trade must be made on a market with a probability below 80% to qualify for the promotion.
• Reward-funded trades: Trades placed using rewards or bonus funds do not count toward the qualifying trade requirement.
• Bonus expiration: Any bonus funds awarded through the OG promotion expire after seven days.
• Claiming window: The promotion is available for seven days after your OG account is verified.
• New users only: The OG.com promo code SIBONUS and welcome offer are available to eligible new users only.
• Offer expiration: The OG promo offer is currently scheduled to expire on December 31, 2026.

Yes, OG.com and the OG predictions promo code SIBONUS are currently available in every state except Arizona.

OG operates as a federally regulated prediction market and is classified as a Designated Contract Market (DCM), which allows it to operate in non-legal betting states. For example, although California sports betting, Georgia. sports betting, or Texas sports betting is not permitted, you can legally trade on sports outcomes at OG. The predictions site is regulated by the Commodity Futures Trading Commission (CFTC) through its relationship with Crypto.com.

Residents of Arizona cannot sign up, register on the site, or claim the OG promo code SIBONUS. Residents of Illinois, Maryland, Massachusetts, Michigan, New Jersey, Nevada, or Ohio can sign up on OG and claim the OG promo code, but are not permitted to trade sports contracts. 

If you live in the Sunshine State, where Florida sports betting remains limited to one operator, OG is now a live and legal option for anyone looking to begin trading sports on a legal and federally regulated prediction market platform.

If you want to learn more about the differences, read our prediction markets vs. sports betting guide.

I found the OG promo code SIBONUS incredibly easy to claim. The offer unlocks after you settle a $10 trade, and you only need one trade to get started, making it one of our best prediction market promos for new traders to claim.

To ensure you receive the $10 bonus on OG, you will need to follow these specific steps, as missing one or more can result in the loss of portions of the bonus funds:

1. Sign up using SIBONUS and verify your account

To begin, go to OG.com using one of the links on this page, then select “Sign Up.” If the OG referral code SIBONUS isn't automatically applied, enter it when prompted.

Enter your email address and ensure you complete the verification process. 

You will also need to provide and verify your mobile phone number. 

Next, you'll be prompted to create a passcode to help protect your account. Afterward, OG will ask you to complete the final steps of your identity verification. This will include submitting your full name, date of birth, and Social Security number (last four digits). It is possible that additional documentation may be needed, such as proof of a government-issued ID, proof of address, and possibly a selfie to confirm your identity.

These verification requests help protect site security and are part of the Know Your Customer (KYC) process. 

2. Make your first deposit

The next step in the sign-up process is making a deposit of $10+. This will allow you to begin trading on sports and real-world events on OG and start unlocking the OG predictions sign-up bonus. 

To deposit, go to your account, choose deposit funds, and select one of the approved methods. Your options will include plenty of legitimate deposit methods, including debit cards, Apple Pay, Google Pay, ACH bank transfers, and wire transfers.

Once you've selected a method, choose a starting amount you feel comfortable depositing. You'll need to deposit at least $10 within 24 hours of completing your verification. 

3. Place your first trade of $10+

Once your account is funded, you can trade contracts across sports, politics, crypto, and more. To begin, find the event you want to trade on, click it, and then locate the 'Yes' or 'No' options within, and choose the outcome you wish to trade on. 

Despite the different terminology, the process of placing a trade on OG is not much different than placing a bet on a sportsbook; you're simply choosing 'Yes' or 'No' on a specified outcome instead of picking a side or total directly. 

To trade, click on a 'Yes' or 'No' option, then set the number of contracts you wish to purchase. The value of each contract will be displayed on your trading slip.

Once your first $10+ trade has settled, you'll have unlocked the $10 bonus.

4. Withdrawing earnings

After you've locked in your trade, you can either wait for it to settle or make an early exit and settle the trade before the event ends. 

Assuming your prediction was correct, or you exited early and secured some early gains, you'll have access to any profits in your account once it settles.

To withdraw funds from OG.com, you'll need to provide your bank details through Plaid and link an eligible bank account. The minimum OG withdrawal is $1, with withdrawal limits of $100,000 per day and $500,000 per month.

Most OG.com withdrawals are processed within 24 hours. Because withdrawals are sent by bank transfer, however, the money may take additional time to appear in your bank account. We recommend allowing approximately 1–3 business days for an OG withdrawal to reach your account after submitting the request.

OG is a dedicated prediction market platform for sports traders, spun off by Crypto.com in February 2026. The site focuses solely on prediction market trading and allows trading on a range of real-world events, with a heavy focus on sports and sports-related markets. 

How does trading on OG.com work?

Trading on OG.com is conducted through Event Contracts, which are regulated derivative products approved by the CFTC. These derivatives (contracts) are offered on a CFTC-regulated exchange via OG technology and allow users to trade binary markets on 'Yes' or 'No' outcomes, a trading process you can learn more about in our full prediction markets guide. 

Much like a sportsbook that offers spreads, moneylines, and player props, you'll find tons of options for trading on sports on OG, including player totals.

How prediction markets work on OG

Each trade you make on OG.com will be executed on a contract priced between $0.01 and $0.99. That price will represent the current implied probability that the market has established for an event to either occur or not occur. 

• For example, a $0.45 price on a 'Yes' outcome would signal a 45% perceived chance of the outcome occurring and a 65% perceived chance of it not occurring ($0.65 price on a 'No' outcome).

When the outcome settles, if your prediction is correct, every contract you buy will close at a fixed value of $1. If you are incorrect, your contracts expire at $0, and you'll lose your initial stake.

Example of a sports prediction trade made on OG.com:

I claim the OG bonus using promo code SIBONUS, and with my bonus and deposit funds, I buy 100 contracts on OG.com at $0.30 each that the Miami Heat will beat the Charlotte Hornets. This costs me $30 because the per-contract price is $0.30.

The Heat wins the game, and since my prediction was correct, each of the 100 contracts I bought pays out at $1.00. This means I get paid an additional $70 on top of getting my stake back, for a total return of $100.

If the Heat had lost the game, I would have lost my entire $30 stake. 

• Total Contracts: 100
• Price: 30% ($0.30 per contract)
• Total Cost (Investment): 100 * $0.30 = $30
• Potential Payout (if you win): 100 * $1.00 = $100
• Net Profit: $100 (Payout) - $30 (Cost) = $70 

While the binary nature of the contracts makes trading on OG predictions similar to betting there are still numerous differences between the two products. Read our prediction markets vs. sports betting guide for more info.  

OG.com always opens to a full display of the most trending and heavily traded sports games of the day. 

Each game display on OG has a sleek, eye-catching design that showcases current prices and a graph of historical price movements. These sorts of graphics provide instant information and help set OG apart from less dynamic sportsbook apps or betting sites. 

Who should use OG.com?

OG is ideal for users who want to speculate on the outcomes of sporting events. While it's a full-service prediction platform where you can trade on all sorts of real-world outcomes, including news and elections, the site's primary focus is event trading on leagues such as MLB and the NFL. 

OG user ratings and feedback

Trading on OG.com can be done on a desktop or through their mobile app. The OG.com app was only released in February of 2026, so there aren't many ratings in either the App Store or on Google Play. However, from a user experience perspective, the OG app delivers much of the same sharp graphics and data we found on our other top prediction market apps. 

🍎 App Store: 4.4/5 ⭐ 981 reviews

🤖 Google Play:4/5 ⭐ 483 reviews

Most of the early OG app reviews in the App Store were positive.

• Users commented on ease of use and how much they enjoyed prediction trading, a testament to how seamless the OG.com app experience was on mobile. 
• A few notes about slow or unhelpful customer service was noted.
• Overall, the start for OG has been strong with a rating between 4.1-4.2 on the App Store and above 4.0 on Android.

We'll keep updating this section as more reviews come in and our sample size grows, so make sure you bookmark it and check back later. For a deeper comparison of how OG.com stacks up as a mobile trading device, check out our guide to apps like Kalshi.

Standout features on OG.com

As a more sports-focused prediction app, OG has a few standout features that users transitioning from traditional sports betting apps or apps like Polymarket will appreciate. 

🪜 OG.com parlay builder

The Parlay builder is a key feature of OG's prediction markets, and its functionality is a key reason we rank OG as one of our best prediction market parlay sites. It allows you to combine 2 to 8 different predictions into a single combo trade for greater potential winnings. Users can combine predictions into a single sports parlay trade, a multi-sports parlay, or a same-game parlay using player props and game lines.

🔚 Early exit feature

This feature is designed to offer flexibility similar to trading stocks or futures. You can use early exit on OG to realize an immediate profit when probabilities shift in your favor (e.g., a team takes an early lead) or to minimize a loss before final settlement.

📊 Integrated social layer

The OG trading app features an integrated social layer designed to foster community engagement alongside its CFTC‑regulated, sports‑focused markets. Features include built-in live trading chat for each event, along with real-time leaderboards that rank users by trading performance relative to the broader community.

🗳️ Diverse event contracts

While OG remains heavily focused on sports, as a full-service prediction-markets app, you'll still find plenty of markets for trading on real-world events, including elections, the release of economic price data, pop culture and entertainment awards, and price action of speculative assets such as crypto. 

🏦 Regulated margin trading (planned)

Alongside Crypto.com, OG plans to be the first prediction market platform to offer trading in margin-based contracts. This option will allow users to leverage their positions in real-world events for other trades. Expect to hear more information from OG.com on this option soon, as it passes final regulatory approval and becomes available on the site.

OG.com at a glance

⭐ SI Verdict 4.6/5: OG's focus on sports trading makes it a great choice for those transitioning from traditional sportsbooks to prediction markets. While the graphics may feel daunting at first, I found that once I became more familiar with prediction markets, the layout and information provided by OG and the OG.com app for each game outcome were extremely helpful. 

Like many event contract platforms, OG.com’s low fees per trade also made it a strong alternative option to sports betting and apps like Betr, especially for those looking to free themselves from the high-commission bets offered at most online sportsbooks.

✅ What works

• Well designed player-focused site and app
• High level graphics allow users to track dynamic price movements with ease
• Parlay builder allows users to combine up to 4 trades together for larger payouts
• Low fees ($0.02 per trade). No fees when correct predictions are settled
• Focusing on sports trading makes it easy for anyone transitioning from sportsbooks to prediction markets

⚠️ What doesn’t

• Very few promotions for existing users
• The new user bonus is lower than at major sportsbooks
• Some restrictions on sports trading in a handful of states
• Finding customer service options on app or website is a challenge

OG.com customer support

One of the most common criticisms of OG in the App Store reviews was the lack of support options. Unfortunately, these seem like valid complaints.

There is no real-time chat where you can get in touch with an actual person for support, so you are left with Crypto.com AI assistants who only provide links to help articles. 

I would expect some of these issues to be addressed in the future, but for now, support options need improvement. 

• In-App Support: Primary support is through the OG.com app and website. Users can log in using shared credentials from their Crypto.com accounts.
• Help Center/FAQ: A comprehensive FAQ section available to all users.
• Crypto.com Support 'Ecosystem': As a "Crypto.com company," OG utilizes the same security and support infrastructure. Support inquiries will often be routed through the general Crypto.com support channels for account, deposit, or withdrawal issues.
• Email Support: Support for crypto.com derivatives trading can be contacted via email (typically contact@crypto.com or through dedicated forms on the help site).
• X (formerly Twitter): 
• @kris (Crypto.com CEO often announces/manages inquiries)
• @OG_com (official site account)

OG.com payment options

Users on OG can access a variety of payment options, including debit cards, Apple Pay, Google Pay, ACH bank transfers, and wire transfers, which makes it one of the best prediction markets for payouts.

At the moment, the only way to request withdrawals is via ACH bank transfers, which is set up through the Plaid payment app. While Plaid is a respectable app, and bank transfers are among the most secure methods for receiving funds, the limited options are a bit of a drawback. 

Overall, expect to see expanded withdrawal methods on OG.com in the near future. 

• Plaid Instant Deposits: Enables immediate funding to begin trading. A seven-day hold applies to instant transfers made using this method.
• Plaid Withdraws: Must use for withdrawals. Processed via ACH bank transfer.
• Debit/Credit Cards: Supported for depositing funds.
• ACH Transfers: Available for bank-to-platform transfers (via Plaid).
• Wire Transfers: Supported for larger transfers.
• Crypto.com Linked Account: Accounts are linked with Crypto.com, allowing for shared USD balances, logins, and verification. 

The main OG Predictions page highlights the event markets currently attracting attention across sports, politics, economics and pop culture. New users can also use OG promo code SIBONUS to earn a $10 bonus after completing an eligible $10+ qualifying trade.

🔥 Trending NFL markets on OG today

NFL Week 5 continues Sunday, Oct. 11, with a full slate of matchups available on OG.com. Traders can access individual game markets, player props, season-long futures and eligible combinations through OG's Parlay Builder.

Here are some of the biggest NFL markets on OG right now.

🏈 Eagles vs. Jaguars – Oct. 11

Philadelphia faces Jacksonville on Sunday morning at 9:30 a.m. ET, with the Jaguars emerging as substantial favorites on OG's prediction markets. Jacksonville is currently priced at 77¢ to win, compared with 24¢ for Philadelphia.

Trending trades to watch on OG.com:

Jacksonville has a commanding advantage in OG's game-winner market, with its 77¢ contract representing an approximately 77% market-implied probability of beating Philadelphia. However, the spread is much closer to even, with Jaguars -7.5 at 50¢ and Eagles +7.5 at 51¢.

The game's total sits at 41.5 points, with Over priced at 52¢ and Under at 49¢. OG also offers additional NFL markets covering player outcomes and eligible combinations.

Important for new users: The SIBONUS OG promo code requires a qualifying trade priced below 80% probability. Jacksonville's 77¢ game-winner contract currently falls within that range, along with the featured spread and total selections. A contract priced at 80¢ or higher would not qualify.

Qualifying welcome-offer trades must also be worth at least $10, including fees, and settle within seven days of identity verification.

OG.com NFL prices checked Oct. 11, 2026. Contract prices and available markets can change before kickoff.

What can you trade on OG for NFL Week 5?

OG's NFL prediction markets go beyond simply picking a winner. Users can trade game winners, point spreads, totals, player props and futures, while the Parlay Builder allows eligible selections to be combined into parlays of up to eight legs.

NFL Week 5 continues Sunday, Oct. 11, with several heavily traded matchups, including Eagles-Jaguars, Bears-Packers and Seahawks-49ers. Here are some of the most interesting game-winner markets currently listed on OG.com.

Jacksonville is one of the strongest favorites featured in OG's Sunday markets, trading at 77¢ against Philadelphia. However, Bears-Packers is considerably tighter, with Chicago at 54¢ and Green Bay at 47¢.

Seahawks-49ers is another closely watched matchup, with Seattle favored at 62¢ compared with 39¢ for San Francisco. OG's listed game volume has exceeded $35,000, while Eagles-Jaguars leads these featured markets with more than $42,000.

There are also several additional ways to trade these matchups beyond the game winner.

New users claiming the SIBONUS OG promo code must remember that qualifying welcome-offer trades must be priced below 80¢. That makes checking the contract price particularly important when considering heavily favored teams.

For example, Jacksonville's 77¢ game-winner contract currently falls within the eligible range, while an outright favorite trading at 80¢ or higher would not qualify. Traders can also look to eligible spreads, totals and player markets to satisfy the welcome offer's trading requirements.

OG.com prices and displayed trading volumes checked Oct. 10, 2026 at 3:40 PM ET, directly from OG's NFL market hub and individual game markets. Contract prices, trading volumes and market availability can change at any time.

OG.com now offers several promotions and rewards for existing users, including weekly NFL promotions and its referral program. Unlike the SIBONUS welcome offer, these promotions don't require you to be a brand-new OG user, although eligibility can vary by account and location.

Here are the main OG promotions for existing users available on October 11, 2026:

🏈 OG.com Pick of the Week: Win up to a $50 trading Boost

OG.com offers a free NFL Pick of the Week contest where eligible users can win a 100% trading Boost worth up to $50 by correctly answering a weekly Yes/No prediction question.

The contest features a $10,000 weekly prize pool, shared equally among users who make the correct prediction. A new question becomes available every Monday, and participants have until Sunday at 8:10 p.m. ET to submit their answer.

Unlike OG's standard trading promotions, no deposit, qualifying trade or purchase is necessary to enter.

How the OG.com Pick of the Week contest works

1. Sign in to OG.com. Both eligible new and existing users can participate.
2. Find Pick of the Week. Open the Pro Football Hub or visit the Promos page.
3. Make your prediction. Select Yes or No on the weekly NFL question.
4. Submit before the deadline. Entries close Sunday at 8:10 p.m. ET.
5. Collect your reward. Correct predictions receive a 100% trading Boost from the weekly $10,000 prize pool. Results and rewards are distributed Monday.

OG.com Pick of the Week bonus details

How much can you win from OG's $10,000 prize pool?

The amount of your trading Boost depends on the number of correct predictions each week. Rewards are distributed equally, with a maximum of $50 per eligible winner.

For example:

Examples assume the full $10,000 pool is distributed equally and are subject to OG's promotional limits.

Important: The reward is not withdrawable cash or a free $50 trade. A 100% Boost increases eligible net winnings from a subsequent successful trade, subject to the Boost's dollar cap.

For example, applying a 100% Boost capped at $25 to a trade that earns $15 in net winnings would provide an additional $15 in promotional earnings. If the trade earns $40, the additional Boost would be capped at $25.

Boosts can be applied to eligible OG markets and expire seven days after issuance. The contest runs weekly, with OG reserving the right to modify or end the promotion.

OG.com Pick of the Week launched Sept. 7, 2026, and is listed as ongoing. Eligibility restrictions and official promotional terms apply.

👥 OG Refer a Friend

OG also currently lists Refer a Friend as an active promotion for eligible existing users. You can find your referral offer in the Promos section of your OG account, where OG provides a unique referral link or code to share with friends.

Referral and welcome offers have separate eligibility rules. You can use the OG referral code SIBONUS to claim the current $10 welcome offer, then start making referrals with your own unique code.

OG currently offers a Refer and Get $10 promotion for eligible existing users.

Once you've claimed the SIBONUS $10 welcome offer, you can find your referral information in your OG account. You can access it from the Promos section and share your unique referral link or code with a friend.

Here's how the current OG referral bonus works:

1. Log in to OG.com and open the Promos section.
2. Select the Refer and Get $10 offer to access your unique referral link or code.
3. Share your referral with an eligible new OG user.
4. Your friend must use your referral code when signing up and complete the requirements shown in the referral promotion.
5. Once the qualifying requirements are completed, the applicable referral reward will be credited according to OG's current promotion terms.

OG referral program breakdown

Referral bonuses can add up fast. If you're looking to get more involved, check out our review of the Crypto.com promo code for another great offer.

If you're more into trading sports than crypto, the Kalshi referral code also allows current users to earn $25 per referral—up to $1,000 in bonus credits.  

The Polymarket referral program also gives existing users another way to earn rewards, with up to $350 in bonuses available for referring eligible new traders.

As mentioned, OG.com is a very sports-focused prediction platform; it even makes our top NFL prediction market apps list. The site offers great options for all major sporting events, including the Super Bowl and March Madness, and the MLB playoffs, including the World Series.

Along with all those big events, you can trade on all regular-season games in the NFL, MLB, NBA, and NHL, plus target predictions for UFC fights, PGA golf, and more.

There are several other non-sport categories you can trade on OG, with sub-menus that include politics, culture, crypto, and economics. For example, right now in the OG.com politics section, you can trade on the US Presidential Election Winner in 2028. 

Other non-sports related options include:

• Culture (award shows, oscars, music, movie releases, TV shows, video games)
• Climate (temperature, forecasts)
• Financials (interest rate decisions, economic indicators, stock market values and prices)
• Companies (overall value, business decisions, OpenAI IPO dates)
• Cryptocurrency (price changes on major cryptocurrencies, including Bitcoin, Ethereum, and Solana)

Live Event Trading on OG

Users on OG.com can trade live as events unfold, making it one of the best NBA prediction market apps to download before this year's season starts. Live Trading is similar to live betting in some respects, where sportsbook users place bets after a game has already started. On OG, traders can buy and sell contracts right up until the moment an event closes, including games in the NBA, MLB, and NFL. 

The main difference is that with live trading, you are not playing a sportsbook-set line and instead react to peer-driven price action. Live trading also allows you to exit any live position you take at any time before the outcome finalizes. This gives you much more flexibility and better leverage than a sports bettor using live betting odds, who must rely on the prices and early cashout options offered by a sportsbook app. 

Trading on a prediction app like OG.com has several small nuances that set it apart from sports betting. Markets and prices are set by peers and public sentiment, and outcomes can be traded right up until they are settled. 

To help you understand how prediction markets work, check out our list of the top strategies to employ as you start on your trading journey. 

🎓 Only trade what you know: Avoid trading markets just because they are exciting or trending. In most cases, traders will be out well in front of breaking news, especially in markets like finance or politics. If you don't follow a sport or event closely, the best option is to avoid it. 

📖 Research before you trade: Take a look at past results, what the experts are saying, and the latest news around each event. By watching trends and staying tuned in to real-time updates, you can give yourself an edge and make smarter calls.

📊 Look for mispriced probabilities: Just like in sports betting, your best edge comes from noticing spots where your research says something’s more likely to happen than what the current market price is giving it credit for.

📝 Understand contract terms: Make sure you’re crystal clear on what counts as a 'Yes' or 'No' result. For example, with player props, double-check the settlement totals. For real-world events, ensure you understand the exact circumstances that will trigger a settlement. 

⚠️ Trade around events where applicable: This works with any solid buy-low, sell-high strategy. Understand potential catalysts when trading on real world evenst to help anticipate volatility. Buy before positive news, and consider selling when Fomo drives prices up.

👥 Diversify your trades: Don't concentrate all your resources or bankroll in a single contract or trade. Diversify investments just like you would in a stock portfolio, across various event types. A more varied portfolio reduces the risk of significant single losses.

💡Manage risk and stay calm: Keep each trade manageable—especially when you’re new and consider cutting risk even more if you think the trade is heading against you too fast. Always base trades on research or projections and not emotions. 

OG does not set or control event contract prices and only acts as a host for the markets. As such, pricing is determined solely by public buying and selling activity. More activity on one side of a trade will generally cause a price shift. Furthermore, each market offers only two trading choices ('Yes' or 'No'), simplifying the process of trading contracts.

Example: A contract for who will win between the Chiefs vs. Patriots starts out at $0.50 for each side (50% probability). However, after more contracts are bought, choosing 'Yes' on the Chiefs winning, the contract price moves to $0.6 on the Chiefs winning and $0.4 on the Patriots winning.

In this sense, it's best to think of price action on a prediction market app such as OG.com as a reflection of the public's perceived likelihood that an event will occur. An outcome that is fluctuating higher in price signifies that the general public believes that the chances of that event occurring are increasing. 

Live trading prices on OG.com

Trading remains open on OG even while an event such as a sporting game is in progress. That also means contract prices can and will change after your purchase and before final settlement, depending on the trading activity of other users. As a purchaser of contracts, you'll retain the right to sell your position, or buy more contracts, at any time before the event ends, at the current market price.

OG.com trading fees

While OG doesn’t set contract prices or charge vig on individual bets that traditional sportsbooks do, it does charge users certain fees.

When you open a position, you’ll be charged a fee of $0.02 for every $1 contract. You won’t pay any fees when your contracts settle. But if you decide to sell your contracts before settlement, there will also be an extra fee of $0.02 per contract.

Here is a full fee breakdown for trading on OG.com:

• Entry Fee: $0.02 per $1 contract to open a position.
• Early Exit Fee: $0.02 per contract if you sell your position before the event settles.
• Position settles in-the-money (correct prediction): Fee waived
• Position settles out-of-the-money (incorrect prediction): No fees

When you don't use early exit and your position settles as incorrect, you'll only lose the amount you put into your trade, at most.
