Kalshi Promo Code SIBONUS for a Trade $10, Get $10 Bonus for New Users 2026

I claimed the Kalshi promo code SIBONUS offer in under five minutes and used the $10 bonus to start trading event contracts immediately. On this page, I'll take you through the entire process step-by-step. The low entry cost and flexible markets make the Kalshi bonus one of the top welcome offers for new traders in 2026.

Kalshi promo code summary for this week

Using the current Kalshi promo code or Kalshi referral code provides a simple sign-up incentive if you're looking to try prediction market promos.

• Offer: You can receive a $10 bonus by registering with our SI-verified Kalshi promo code SIBONUS.
• Eligibility: The offer is available to new users only who complete account registration and identity verification.
• Key conditions: A minimum deposit of $1+ is required to activate the offer, and users must complete at least $10 in trading activity to unlock the bonus. The bonus is awarded regardless of individual trade outcomes.

You should view the Kalshi bonus code as a way to test the platform’s functionality rather than a high-value bonus. The offer provides enough flexibility to explore different markets, evaluate pricing behavior, and decide whether Kalshi’s trading model aligns with their preferences.

Note: The Kalshi promo code featured on this page is distinct from the Kalshi referral code, which is tied to the platform’s refer-a-friend program and is available only to existing users after completing registration. I’ve also noticed many users search for the Kalshi referral code when looking for the welcome bonus, even though the two offers are entirely separate.

Claiming the Kalshi welcome offer is straightforward. Just input the current Kalshi promo code SIBONUS during sign-up, make a qualifying deposit, and complete the minimum trading requirement to unlock the $10 bonus.

While the bonus is easy to claim, there are some key terms to keep in mind:

• You must be 18 years or older and a new Kalshi user.
• You must input the Kalshi promo code SIBONUS during registration.
• Account registration and identity verification are required. This may include submitting a government-issued ID and a selfie.
• A minimum deposit of $1 is needed, and at least $10 in trades must be completed to unlock the bonus.
• Bonus funds are credited to your account and can be used across available prediction markets.
• The bonus is awarded regardless of your trade outcomes.

Claiming the Kalshi bonus code 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 or referral 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 $10 worth of trades, you will be credited with the $10 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.

Unlike sportsbooks, Kalshi doesn’t set odds or take the other side of a bet. Prices are determined by market activity, and users trade directly with one another using U.S. dollars under federal regulation. This structure offers an alternative to traditional betting apps, especially if you're interested in sports-related markets alongside political and cultural events.

It’s important to note that the price of a Kalshi 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 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.

Yes, Kalshi operates as a regulated event trading platform in the U.S., which means it doesn’t fall under the same 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 platform for trading real-world event contracts, including sports-related markets.

Kalshi has also encountered legal challenges in states such as New Jersey, California, Texas, Maryland, and New York; however, as of early 2026, no final prohibitions have been enacted in these states.

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. Fees are 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.

🏈 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.

📈 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.

Who Kalshi is 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 offers rewards for both new and existing users, but the promo code and referral program work differently. The promo code is designed for first-time users claiming a welcome bonus, while the referral code rewards existing users for inviting friends to the platform.

Kalshi promo code

New users can use the Kalshi promo code SIBONUS during registration to unlock a $10 bonus after making a qualifying deposit and completing the required trading activity. The bonus is credited directly to your account and can be used across Kalshi’s prediction markets.

Kalshi referral code

Existing users can also earn rewards through Kalshi’s referral program. By sharing the unique referral code found in the Account section, users can receive a $25 bonus for each friend who registers, deposits funds, and completes the required trading activity within 30 days.

The referral system works similarly to traditional sportsbook referral bonuses and can be a useful way to build your bankroll over time, with users earning up to $1,000 through successful referrals.

It’s also worth noting that many users search for a “Kalshi referral code” when looking for the welcome offer, but the two are separate promotions. The referral code is only available after completing registration and creating an account.

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 best prediction market apps, built for users who want to trade prediction markets directly from their phone. I used the 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 more like a marketplace where participants interact with one another, and prices are set by collective trading activity rather than by a central operator.

• Traditional model: user vs. bookmaker
• Kalshi model: user vs. other market participants
• Pricing emerges from supply and demand, not a set line

Kalshi vs. Polymarket

The Kalshi promo code is easier to claim for U.S. users thanks to its $10 trading requirement and streamlined onboarding process. While the Polymarket promo code offers a larger trading bonus, Kalshi provides a more beginner-friendly experience with regulated U.S. market access and deeper sports-focused coverage 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, making it the better fit for casual users looking to start trading quickly.

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.

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 markets tend to shift based on the news cycle, major sports moments, and upcoming political or cultural events. Below you'll see what the hottest markets are today:

🔥 Men's World Cup Winner

International soccer's biggest prize draws massive global interest, making this one of the most actively traded markets on Kalshi right now.

🔥 Pro Basketball Champion

One of the most bet-on sports markets on the platform ($220+ million in volume), with odds shifting constantly as the season reaches its most critical stages.

🔥 Stanley Cup Champion

Hockey's championship race is heating up, and this market consistently attracts high volume as the field narrows and the stakes rise.

Kalshi provides access to a broad array of prediction markets that let you trade contracts based on the outcomes of real‑world 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: Contracts on championship outcomes, team accomplishments, and other broad sports events.
• Politics: Outcomes tied to elections, legislative decisions, or government actions.
• Economics: Markets based on economic indicators such as interest rate changes and employment data.
• Culture: Predictions related to entertainment and cultural milestones, such as award events or major media achievements.
• Climate and weather: Contracts tied to environmental events or measurable weather outcomes.
• Tech and science: Markets covering developments in technology, scientific milestones, or policy impacts.
• Finance and companies: Prediction markets linked to company performance, financial outcomes, or broad market data.
• World events: Markets that track trending topics in public attention or major global developments, resolved based on verifiable reports or coverage.

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.
