Kalshi Promo Code SIBONUS: Up to $500 in Bonuses July 2026

The Kalshi promo code SIBONUS unlocks up to $500 in bonuses for new users when you complete $25 worth of trades on sports, politics, or other real-world events. This is now the largest welcome offer you can claim on Kalshi, a leading CFTC-regulated prediction market app.

I’ll share how I claimed the Kalshi welcome offer and explain how to trade sports contracts with your Kalshi bonus funds today.

Kalshi promo code summary for July 2026

When you enter the Kalshi promo code SIBONUS during registration, you'll get access to a welcome offer that will allow you to earn up to $500 in bonuses with one of our top prediction market promos. 

To get started, users must deposit $10 or more and settle at least $25 in trades within seven days on the platform to unlock the Kalshi bonus. 

What are the details of the Kalshi sign-up bonus?

When I claimed the Kalshi offer, my first step was to enter the current Kalshi promo code, SIBONUS, during registration. The sign-up and identity-verification process was straightforward, and I was ready to fund my account within a few minutes.

To qualify for the up to $500 welcome offer, I needed to deposit enough to complete up to $25 worth of trades within seven days on the platform. I used PayPal, which is a supported option on Kalshi, and was able to deposit USD funds into my account immediately. I added a little more than the $25 required to qualify for the bonus so I could try out sports and real-world markets I can't access on sportsbooks like politics.

After completing the deposit, I decided to clear the bonus in a single trade by making a $25 trade on a simple MLB game outcome. When that trade settled, my Kalshi bonus was credited to my account, giving me even more funds that I then used to try out new real-world event markets.

Overall, I found that Kalshi's exchange-style pricing delivered exactly what it promised as one of the best prediction market apps, eliminating the traditional sportsbook vig, so wins were paid without a reduction for bookmaker margins.

Claiming the Kalshi sign-up bonus is straightforward. Just input the current Kalshi promo code SIBONUS during sign-up, make a qualifying deposit, and complete the minimum $25 trading requirement within seven days on any prediction market, and you'll unlock the chance to earn up to $500 in bonuses.

While the Kalshi promo is easy to claim, here are some key terms to keep in mind when claiming your bonus:

• You must be 18 years or older and a new Kalshi prediction markets user to qualify.
• You must input the best Kalshi promo code SIBONUS during registration.
• Account registration and identity verification are required. This may include submitting a government-issued ID and a selfie through KYC verification.
• A minimum deposit of $10 is required, and at least $25 in trades must be settled to unlock the Kalshi welcome bonus.
• You must complete your $25 worth of trades within seven days of registering.
• After you meet the bonus terms, funds are credited to your Kalshi account and can be used across available prediction markets.
• Any bonus credit must be used within seven days of being granted. Bonus credit not used within that 7-day period will expire and be forfeited.
• Everyone who claims the Kalshi promo code offer will receive a bonus and the chance to earn up to $500
• Bonus amounts are random and are awarded at Kalshi's sole discretion; only a small number of users will receive $500 as their welcome offer.
• The bonus is awarded regardless of the outcomes of your initial trades.

After you sign up and claim the Kalshi welcome offer, you'll be free to use the site and your bonus funds for event trading across sports, politics, culture, and more. 

Claiming the Kalshi sign-up bonus is straightforward and mirrors the process used by most regulated trading platforms to onboard new users. Once your account is set up, you get full access to Kalshi’s marketplace of real-world event contracts, including sports-related markets.

I had everything up and running in just a few minutes.

1. Create an account

Start by registering for a Kalshi account through the platform’s sign-up page. Ensure you enter the current Kalshi bonus code, SIBONUS, when prompted. You’ll also enter basic personal details, but account creation typically takes just a few minutes.

2. Verify your identity

As a regulated exchange, Kalshi requires identity verification before you can trade. This process may include confirming your date of birth, address, and identity using government-issued identification. These checks are standard across compliant financial and trading platforms.

3. Fund your account

Once verified, you’ll need to add funds to your Kalshi wallet. Kalshi supports multiple payment methods, including debit cards and cryptocurrencies, allowing you to deposit with a low minimum deposit. A qualifying deposit is required for promo eligibility, though additional trading activity is typically needed to unlock any bonus.

4. Place your first trade

After funding your account, you can place your first trade on any available market, including sports-related event outcomes. Once you complete $25 worth of trades, you will be given the chance to earn up to $500 and be credited with a bonus.

Kalshi is a regulated prediction market platform where you trade 'Yes' or 'No' contracts tied to real-world events, such as sports outcomes or presidential elections. Contract prices range from $0 to $1 and reflect the market's likelihood of an outcome.

For example, a contract trading at 20.1¢ implies the market believes there is roughly a 20.1% chance of that outcome occurring.

Unlike sportsbooks, predictions on Kalshi don't use fixed odds or involve taking the other side of a bet. Prices are determined in a peer-to-peer marketplace, and users trade directly with one another using U.S. dollars under federal regulation. This structure offers an alternative to traditional betting apps, where bettors only have access to bookmaker prices that include vig, the fee a sportsbook charges for accepting your wager.

How does prediction market trading on Kalshi work?

It’s important to note that the price of a Kalshi prediction contract is not fixed. Market prices are dynamic, fluctuating between 1 cent and 99 cents, reflecting the market's perceived probability of a specific event.

Contract prices reflect traders' collective opinion and represent the implied probability of a 'Yes' or 'No' outcome.

• If a 'Yes' contract is priced at $0.70, the market believes there's a 70% chance the event will happen. The 'No' contract would be priced around $0.30.
• When an event settles, each winning contract pays $1, and each losing contract expires at $0.
• Your profit is the difference between the $1 payout and your purchase price, minus trading fees.

Example:

I bought 100 contracts on Kalshi predictions at $0.70 each that the Boston Celtics would win their game against the Los Angeles Lakers. This cost me $70 in total.

The Celtics went on to win the game, and each contract settled at $1.00. I received a $100 payout, which included my original $70 stake plus a $30 profit.

Kalshi operates as a legal and federally regulated event trading platform in the U.S. It does not fall under the same state-level licensing framework as traditional sportsbooks or social and sweepstakes casinos.

At the federal level, Kalshi is registered as a Designated Contract Market (DCM) and regulated by the Commodity Futures Trading Commission (CFTC), which oversees derivatives and event-based contract trading. The platform also follows industry-standard security measures, including SOC 2 Type II compliance and SSL encryption, to protect user data and transactions.

These compliance and regulatory standards make Kalshi a legitimate and fully legal platform for trading real-world event contracts, including sports-related markets. It also makes Kalshi a legitimate and legal option for anyone interested in event trading in states where sports betting has not been legalized. For example, California sports betting, Georgia sports betting, and Texas sports betting are illegal, but if you're in those states, you can safely trade sports contracts with Kalshi. 

The same goes for Florida sports betting, which allows one online operator through the state's tribal compact but does not outlaw federally regulated sites like Kalshi.

As of early 2026, no final prohibitions have been enacted in these states, making Kalshi a viable and fully legal option for residents looking to speculate on sports outcomes.

Kalshi state guides

Kalshi is legal in all states outside of Nevada. For places where sports betting isn't legal or limited in the U.S., you can still use the Kalshi app. Below, you can find breakdowns of Kalshi's legal standing and how they operate in each of those states.

• Kalshi California
• Kalshi Florida
• Kalshi New York
• Kalshi Texas

Kalshi’s platform is built around trading event-based contracts, with pricing driven by market activity rather than fixed odds. You can enter and exit positions, view transparent pricing before each trade, and access markets across sports-related outcomes, politics, economics, and culture, all with the help of the Kalshi welcome bonus, which lets you earn up to $500 in bonuses.

Trading fees are also displayed upfront and tied to trading activity, helping you understand costs before committing funds.

Key features at a glance

🧩 Kalshi Combos

Kalshi Combos let you group multiple event outcomes into a single trade, similar in concept to a sportsbook parlay. Each combo’s payout is based on how every leg resolves, with partial resolutions factored into the final settlement. Combos are higher-risk by design but allow you to express more specific, multi-outcome views within a single position. A built-in combo builder makes it easy to assemble and submit these trades directly in the app.

🏈 Kalshi NFL player prop markets

Kalshi offers player-specific sports markets, allowing you to trade contracts tied to individual performances, such as scoring outcomes. These markets expand Kalshi’s sports coverage beyond team results and provide more granular ways to engage with major leagues.

📈 Kalshi live event trading

While contracts resolve based on final outcomes, Kalshi allows you to trade positions while an event is active. This gives you flexibility to react to new information, adjust exposure, or lock in gains before an event concludes. That alone makes it a top option for consistent MLB traders who have access to hundreds of regular-season game markets every day. 

🖥️ Kalshi Pro trading terminal

Kalshi Pro is a professional desktop trading platform that is now in beta and free to try on the site. It's built for active prediction market traders and features powerful market scanners to identify new trading opportunities, fully customizable multi-market layouts, and advanced order management that lets you place and manage multiple open orders simultaneously. 

Does Kalshi have a promo code?

Yes, you can use the Kalshi promo code SIBONUS during registration to claim the platform's best available new-user welcome offer. New users who sign up with our code and trade $25 or more will get a chance to earn up to $500 in bonuses, the largest offer currently available to new users on Kalshi. I tested the offer myself and had the bonus unlocked within minutes of completing my $25 worth of trades.

Who is Kalshi best suited for?

Kalshi is best suited for users interested in forecasting real-world outcomes through a market-based model. That includes me as a sports fan who enjoys tracking games through a more analytical lens, along with data-driven users who follow trends and probabilities, and traders focused on politics, policy, or major news events.

It appealed to me because I like analyzing information over time and adjusting positions as new data becomes available. The platform works well for that kind of flexible, information-driven approach. Those who prefer simple win-or-lose bets, large promotional bonuses, or traditional parlays may find standard sportsbooks a better fit.

Kalshi’s platform operates like a regulated prediction market, with costs and restrictions tied to trading mechanics rather than fixed sportsbook odds. Understanding fees, position limits, and withdrawal rules can help you plan trades and manage funds effectively.

💸 Trading fees

Kalshi charges variable transaction fees instead of building costs into the odds (often called the “vig” at sportsbooks). Fees are shown upfront and depend on how your order is filled. Taker fees, which apply when a trade is immediately matched, typically range from about $0.07 to $1.75 per contract, while maker fees for orders that add liquidity to the market are lower, generally $0.02 to $0.44 per contract. Fees tend to be highest for evenly priced markets (around $0.50) and lower for contracts priced near the extremes.

📊 Trading limits

Markets on Kalshi may have trading caps or position limits that vary depending on liquidity. Low-liquidity markets can produce less stable pricing, while high-liquidity markets allow more predictable trading outcomes. You should review individual market rules before committing significant funds.

💳 Kalshi payment methods

Kalshi supports several funding and withdrawal options, though availability is currently limited. Cryptocurrency payments in USDC carry no fees, while Visa and Mastercard transactions may incur a $2 fee per transaction.

Withdrawals are processed according to the selected payment method and are subject to standard verification procedures. You should allow time for identity verification and fund transfer when planning to move money off the platform.

Kalshi is one of the top mobile trading apps, and built for users who want to trade prediction markets directly from their phone. I used the Kalshi app to access available markets, open positions, account balances, and trade history, which made it easy to manage activity without switching to a desktop platform.

From a usability standpoint, the app focuses on clarity and speed. I found that markets are clearly labeled, contract pricing is easy to follow, and placing a trade only takes a few taps. Switching between sports-related markets and other event categories is seamless, making it easy for me to react quickly as prices move.

Kalshi is available on major mobile app stores, giving me a native app experience rather than relying solely on a mobile browser. Overall, I found the app delivers a streamlined, user-first experience that works well whether I’m casually checking markets or actively monitoring them throughout the day.

Kalshi works differently from traditional sports betting apps, both in how prices are set and how positions are managed.

Trading probabilities vs. betting odds

Traditional sports betting is built around a fixed price at the moment you place a wager. That price already reflects the bookmaker’s margin, and your outcome is locked in once the bet is placed.

• Pricing is static once the bet is made
• The “edge” is built into the odds from the start
• Your position typically doesn’t change unless a cash-out option is available

Kalshi, by contrast, is centered on changing probabilities. Prices move as new information enters the market, meaning your position can evolve in real time rather than staying fixed.

• Prices adjust as market expectations shift
• Contracts reflect changing probability, not static odds
• Positions can be adjusted before the event resolves

Market structure

Traditional sportsbooks take the opposite side of every bet and manage risk internally through pricing and exposure control.

Kalshi operates as a peer-to-peer marketplace where participants interact with one another, and prices are set by collective trading activity rather than by a central operator.

• Traditional sportsbook model: user vs. bookmaker
• Kalshi prediction markets model: user vs. other market participants
• Kalshi prediction markets pricing: Contract prices emerge from supply and demand, not a set line

You can read our prediction markets vs. sports betting guide for a deeper look at the differences between the two.

Kalshi vs. Polymarket

The Polymarket promo code offers a standard deposit bonus of $50 and features the largest and most liquid trading markets, as detailed in our Polymarket review. The Kalshi welcome offer isn't guaranteed to exceed the Polymarket offer in value, but certain new users on Kalshi will get significantly more than $50 when they sign up with SIBONUS, making it a more exciting offer overall.

For a more detailed breakdown between these two platforms, read our Kalshi vs. Polymarket page.

Kalshi vs. OG

The OG promo code is geared more toward sports-focused traders who want social and community-style features alongside prediction markets. Kalshi offers a simpler platform experience and a lower barrier to entry, with a welcome offer that has significantly more upside, making it the better fit for casual users looking to start trading quickly.

Kalshi vs. ProphetX

The ProphetX promo code offers new users a strong alternative to prediction market platforms, with a 'Trade $10, get $20 bonus' offer that requires just one qualifying settled trade of $10+. ProphetX may appeal more to event traders, as it only requires trading $10 to claim.

Kalshi vs. other prediction sites

Looking for a platform that combines prediction markets with cryptocurrency trading? The Crypto.com referral code gives users access to both event trading and one of the world’s largest crypto exchanges, making it a stronger fit for those seeking broader digital asset exposure beyond prediction markets alone.

If you prefer a fantasy sports-style experience instead of traditional prediction contracts, the Underdog promo code offers entry bonuses for new users completing paid contest entries. It’s a popular alternative for sports fans seeking a more gamified experience than Kalshi’s market-based trading model offers.

Additionally, while there isn't a welcome offer available yet, you can join the waitlist for the ROLR prediction market promo code.

You can read our apps like Kalshi or apps like Polymarket page if you want more details on other prediction market platforms.

Kalshi’s most active prediction markets tend to shift based on the news cycle, major sports moments, and upcoming political or cultural events.

Markets are grouped into topic categories so you can explore areas that match their interests and expertise, with each contract resolving according to clear, predefined rules.

Types of event categories on Kalshi include:

• 🏈 Sports: Trade prediction markets on game winners, player props, championships, futures, and other major sporting events.

Each category may contain dozens or hundreds of individual contracts that update in real time and are priced between $0 and $1 based on market sentiment.

Because regulatory interpretations vary by jurisdiction, some markets, particularly sports‑related ones, may be restricted or unavailable in certain states. Where relevant, Kalshi will disclose any regional limitations directly on the platform or during account setup.

Kalshi prediction markets involve financial risk, and outcomes are never guaranteed. Contract prices reflect market sentiment at a given moment, but real-world events can change quickly and resolve in unexpected ways. As with any regulated trading platform, users should only commit funds they can afford to lose.

Kalshi provides tools and account-level controls designed to support responsible participation, including balance visibility, transaction history, and the ability to manage or limit activity. These include optional trading breaks, voluntary account opt-outs, and self-set funding limits, all of which can be adjusted within your account settings. Taking time to understand how contracts work and setting personal limits can help ensure a more informed and measured trading experience.

Kalshi offers several support options to help you with account setup, verification, funding, and general platform questions. While availability varies by channel, the most common issues can be resolved through Kalshi’s on-site resources or by contacting the direct support team.
