What we found on kalshi.com
We checked kalshi.com and its sign-up page while logged out on October 6, 2026, and neither shows a promo code or welcome bonus. Promo codes you see on other sites usually belong to those sites’ partner deals with Kalshi, and their terms can change without notice.
How the referral program works
Kalshi’s referral program is the one offer it documents for new users. According to its help centre:
- It’s for US users only.
- A referral code can be added within 72 hours of your first login, so you can’t add one later.
- Credits from referrals must be used within 7 days.
- There’s a lifetime cap on how much you can earn from referrals.
- The amounts are shown in the Rewards section of the app, not on the website.
Kalshi issues a 1099-MISC for credits and rewards once you pass the IRS threshold, so keep track of what you receive.
Is Kalshi worth it without a bonus?
We think so. Kalshi is our top-rated app at 4.4 out of 5 because of its range of markets, its app and its free withdrawals, and it pays a variable 3.50% APY on balances of $250 or more, which is worth more than most sign-up bonuses if you keep money there. If a bonus matters to you, Polymarket US has a $25 offer for a $10 deposit through some sign-up links; see our Polymarket promo code page.
