Kalshi Referral Code: Use SIBONUS for up to $1,000 in Bonuses

The Kalshi referral code lets you earn $25 per referral — and up to $1,000 in total bonus credits — when you invite friends to trade on the platform. Sign up today using code SIBONUS to claim a $20 welcome bonus, then make $100 worth of trades to unlock your unique referral link. Share your link and receive a bonus every time a friend verifies their account and completes $100 in trades. 

Input the Kalshi promo code SIBONUS when signing up to claim your $20 welcome bonus, then start referring friends to earn an additional $25 per successful referral.

Here's a quick look at how the Kalshi referral program works.

Key points of the Kalshi referral code program

• Share your Kalshi referral code with a friend who doesn't already have an account.
• Your friend must sign up using your link, complete identity verification, and make a deposit.
• Once your friend completes 100 trades within 30 days, both users receive a $25 trading credit.
• The bonus itself isn't withdrawable; only profits earned from trading with it can be withdrawn.
• The bonus allows you to earn up to $1,000 via referrals using your unique link.

To get the most value, remember to use the SIBONUS bonus code at sign-up. This unlocks the $20 Kalshi welcome bonus and sets you up to start earning Kalshi referral bonuses when you refer friends to the site on top of that.

📝 Register

Click through to Kalshi using the links on this page and create your account or input code SIBONUS when registering. You'll be prompted to enter a code during sign-up — make sure to complete identity verification (Know Your Customer/KYC) to fully activate your account and access all features.

💳 Deposit funds

Once registered, fund your account. This is a required step before you can begin trading and before the welcome offer and referral program become accessible.

🎯 Complete your first trades

Trade $20 to trigger the $20 Kalshi welcome bonus. From there, continue trading to hit the 100-trade threshold, which unlocks the Kalshi referrals section, at which point you can start earning $25 per friend you refer, up to $1,000.

Once your Kalshi account is set up and the referrals section is unlocked, the process to start claiming rewards with the Kalshi referral program is straightforward.

Kalshi is one of the best prediction market apps in the U.S., and its referral program is easy to navigate when you follow these steps:

1️⃣ Find your referral link

Log in and open the waffle menu — top-left on mobile, top-right on web — and tap Invite Friends. This is where your unique Kalshi referral link lives.

2️⃣ Share it with a friend

Send your link via text, email, or any messaging platform. Your friend must not already have a Kalshi account, and they need to use your link at sign-up for the referral to count.

3️⃣ Your friend signs up and verifies their account

Your friend creates their account through your link and completes identity verification (KYC). This step is required before any trading can begin.

4️⃣ Your friend deposits and completes 100 trades within 30 days

Your friend must fund their account and complete 100 trades within 30 days. With Kalshi being one of the top World Cup prediction market apps and the tournament offering a wide range of contracts to trade, hitting that requirement can be more achievable than it sounds.

5️⃣ Both of you receive a $25 trading credit

Once the requirement is met, the bonus is released automatically to both accounts — no manual claim needed. Check your Account Activity to confirm it was applied.

The Kalshi referral code program is only available to certain users. Before sharing your link, make sure both you and your friend meet the following requirements.

• You must be an existing Kalshi user: Only registered users with a verified account can access and share a referral link.
• Your friend must be a new user: The $25 bonus is only valid for first-time sign-ups who haven't previously created a Kalshi account.
• Both users must be U.S. residents (outside of Nevada): Kalshi's referral program is not available to international users or those located in Nevada.
• Both users must meet legal requirements: This includes being 18 or older and completing identity verification (KYC) before any trading can begin.
• Your friend must meet the trading requirement: They must sign up through your unique Kalshi referral link, make a deposit, then complete 100 trades within 30 days for either of you to receive the bonus.

One of the best ways to maximize your rewards with the Kalshi referral bonus is to combine the welcome bonus with the platform's referral program from the start. I used this strategy when I was getting started, and the extra credits helped me build my balance much faster.

• Welcome offer: New users who sign up with promo code SIBONUS and place at least $20 in trades will receive a $20 trading bonus. It's a straightforward, low-cost offer that gives you extra funds to explore Kalshi's prediction markets.
• Referral program: After creating your account, you can start inviting friends to join. For every successful referral, both you and your friend receive $25 in trading credits. As referrals add up, so do your rewards, with the opportunity to earn as much as $1,000 in referral bonuses.

By claiming the welcome bonus and sharing your unique referral link early, you can grow your trading bankroll faster while minimizing your own out-of-pocket investment.

If you’re considering more apps like Kalshi, there are other platforms to compare, such as Kalshi vs. Polymarket. Each of the top prediction market platforms has its own referral programs and welcome offers that you can combine to grow your account balances.

Additionally, our prediction market guide breaks down everything you need to know.

As we detail in our Kalshi review, the prediction market app has plenty of great features, including the Kalshi referral code program, which is one of the more straightforward ways to earn on the platform. Users in California, Florida, and Texas can also use the Kalshi referral code to start predicting sports outcomes for upcoming World Cup matches and beyond. 

However, the program is not without its limitations. Some of the main features of the program worth knowing before you start sharing your link include:

Pros

✅ Both users get rewarded

Every successful referral earns you and your friend $25 in trading credits, a straightforward win-win that grows both of your balances at no extra cost.

✅ No manual claim required

Once your friend meets the trading requirement, the bonus is released automatically to both accounts. No hoops to jump through after the fact.

✅ Low barrier to get started

Stack it with the $10 welcome offer, and you can build a trading balance quickly without putting much of your own capital at risk.

Cons

✖ 100-trade requirement is a high bar

Your friend must complete 100 trades within 30 days to trigger the bonus, which can be demanding for some users.

✖ Bonus credits aren't withdrawable

The $25 referral credit is designed for trading only. You can withdraw profits made from it, but not the bonus itself.

If you're active in prediction markets or sports betting, referral programs are one of the best ways to stack value across platforms. Here's a quick look at what else is out there.

Kalshi isn't the only prediction market running a referral program. A few others worth knowing:

• Polymarket – One of the largest crypto-based prediction markets. Instead of a flat sign-up reward, it uses a two-tier revenue-sharing model in which referrers earn lifetime commissions of up to 30% on their friends' trading fees.
• Crypto.com – Offers a milestone-based referral structure paid out in its native CRO token. Both parties can unlock up to $50 on the mobile app or up to $2,000 on the exchange, depending on the new user's trading and staking volume.
• OG.com – Both the referrer and the new user can earn up to $150 each in trading bonuses, unlocked progressively based on the friend's 30-day trading milestones.

Sportsbook referral bonus programs

If you also bet on sports, most major sportsbooks have referral programs running alongside their welcome bonus offers. We cover the best ones in detail — including how to claim them, what the requirements look like, and how they stack up:
