Once your Kalshi account is set up and the referrals section is unlocked, claiming rewards through the Kalshi referral program is straightforward.

For a more detailed explanation of how to unlock the Kalshi referral program, follow these specific steps:  

1️⃣ Find your Kalshi referral link

Log in to your Kalshi account and open the waffle menu in the top-left corner on mobile or top-right corner on desktop. Select Invite Friends to find your unique Kalshi referral link.

This personalized link acts as your Kalshi referral code, so make sure your friend uses it when creating their account.

2️⃣ Share your Kalshi referral code or link

Copy your referral link and send it to your friend by text, email, or your preferred messaging app.

To qualify for the referral bonus, your friend must be an eligible new Kalshi user and register for the prediction market platform through your unique referral link. If they create an account separately, the referral may not be tracked.

3️⃣ Your friend creates and verifies a Kalshi account

Your friend can follow the referral link to sign up for Kalshi and complete the required account verification process.

They should make sure they meet Kalshi’s eligibility requirements before depositing or trading.

4️⃣ Your friend deposits and completes the trading requirement

After registering, your friend must fund their Kalshi account and complete the applicable trading requirement within 30 days of signing up.

Kalshi offers event contracts across categories including sports, politics, economics, weather, entertainment, and more, so users can choose which eligible markets they want to trade.

The exact referral requirements and promotional terms can change, so check the offer displayed in Kalshi before depositing or trading.

5️⃣ You both receive a $25 Kalshi trading credit

Once your friend completes the qualifying referral requirements, Kalshi automatically adds a $25 trading credit to each eligible account. You both now have bonus funds to use on the best NFL prediction market app.

There’s no separate bonus code to redeem or reward to claim afterward. You can check Account Activity in Kalshi to confirm when your referral credit has been added.

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 NV and WA): Kalshi's referral program is not available to international users or those located in Nevada and Washington.
• 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 the trading requirements 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 Kalshi referral code program from the start. I used this strategy when I was getting started, and the extra credits helped me build my balance much faster.

Here are the steps I followed to ensure I took full advantage of both offers:

1. Claim the welcome offer: New users who sign up with promo code SI35 on Kalshi and place at least $25 in trades will receive a $35 bonus. It's a straightforward, low-cost offer that gives you extra funds to explore Kalshi's prediction markets.
2. Complete the referral requirements: Complete $100 or more in trades. This will give you access to the referral section on Kalshi, where you'll find your unique referral link, which will let you start inviting friends to the platform.
3. Begin inviting friends with your referral link: After creating your account and meeting the trading requirements, 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 or Kalshi vs. PredictIt. 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 offers plenty of great features, including the Kalshi referral code program, one of the most straightforward ways to earn on the platform.

Users looking for the following:

• California sports betting
• Georgia sports betting
• Florida sports betting
• Texas sports betting

Can also use the Kalshi referral code to start predicting sports outcomes.

However, the program has 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 $35 welcome offer when you use the Kalshi code SI35 at sign-up, and you can build a trading balance quickly without risking much of your own capital.

Cons

✖ Trading requirement can be a high bar

Your friend must verify their identity and complete the trading requirement displayed in their Kalshi Rewards section before the referral bonus is released, which may require more trading activity than some competing platforms

✖ Bonus credits aren't withdrawable

The $25 referral credit is designed for trading only. You can withdraw profits made from trading with 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 – When you use the Polymarket referral code, you can earn $25 per referral up to 14 times. This can net you a total of $350 in bonuses.
• 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.
