Search for a Kalshi referral bonus and you will be given a number within two seconds. Twenty-five dollars. Fifty. Up to five hundred. Up to a thousand. The pages quoting those figures rarely agree with each other, and none of them agree with the one source that actually governs what you get paid. Kalshi’s own referral FAQ declines to state an amount at all, and the reason it declines is the most useful thing to understand before you sign up.
Terms taken from Kalshi’s own help center referral FAQ and its referral program terms page on 17 October 2026. Amounts vary by offer, so the figure that binds is the one attached to the offer in your account.
Why Nobody Can Quote You a Reliable Number
Kalshi does not run a single fixed referral bonus. It runs offers, plural, and the terms attached to each specific offer govern that offer. The help center is explicit that its guidance is general and that the offer’s own terms control eligibility, bonus amounts, qualifying activity, deadlines, limits and restrictions.
Two things follow from that, and both are worth internalizing.
First, any third-party page stating a flat Kalshi referral amount is reporting one offer they saw at one moment, which may not be the offer attached to your account today. The spread between the figures circulating right now is wide enough on its own to prove the point.
Second, an “up to” figure is a maximum rather than a promise. Kalshi says so directly. A page advertising up to 500 dollars is describing a ceiling that most participants will not reach.
The practical move is simple. In the app, open Explore, then the menu, then Your rewards, then Offers. Select the offer and read the requirements and linked terms there. That is the number that will actually be paid to you.
The Rules That Do Not Change
While the amounts move, the structure has been consistent, and these are the parts worth planning around.
- Both sides must qualify separately. Bonus credits are not automatic on sign-up. The referrer and the referee each have to satisfy their own requirements before either one is eligible for anything.
- The referee’s qualifying activity is a trade of at least 25 dollars on Predictions within 7 days of opening the account. That is a tight window by the standards of this category.
- The referrer also has to have traded at least 25 dollars on Predictions. You cannot open an account, share your link immediately and collect.
- Referral offers are currently available only to eligible US users.
- Identity verification is required, and a code can be applied after signing up only within a limited window.
The Seventy-Two Hour Rule That Catches People
If no code was attached when you registered, you can still add one, but only within 72 hours of creating your account.
Kalshi spells out two details that make this stricter than it sounds. The clock starts at account creation, not at identity verification, so a slow verification process eats into your window rather than pausing it. And logging out and back in does not restart it.
This matters because Kalshi’s sign-up flow asks for a Social Security number and verification can take time. Someone who registers on a Friday, gets verified on Monday and then goes looking for a referral code has already lost. Apply the link first, before you create the account, and the question never arises.
Credits Are Not Cash, and They Expire Fast
This is the part most write-ups skip, and it changes the value of the whole offer.
Kalshi says referral rewards may be issued as trading credits with withdrawal restrictions. Some require you to trade the credited amount on an eligible product before any of it can be withdrawn. Standard withdrawal holds apply on top of that.
The referral program terms go further and put a clock on it. Bonus credit must be used within 7 days of being granted, and unused credit expires and is forfeited.
Seven days is short. It means the reward is not something you can collect and leave alone while you decide what to do. If the credit lands on a Tuesday and you do not place a qualifying trade by the following Tuesday, it is gone, and nothing is recoverable.
So a Kalshi referral is best understood as a discount on trading you were already going to do that week, not as a deposit into your account. Anybody signing up, collecting credits and planning to withdraw them untouched has misread the program.
Perpetual Futures Referrals Work Differently
Kalshi has a separate referral mechanic for its perpetual futures product, and the two should not be confused.
For a perps referral, the friend has to fully enable perps on their account. Signing up for Kalshi alone does not count toward it. The reward is not a one-off credit either: it is a share of the trading fees your referral generates, paid weekly.
That is a fundamentally different proposition. A fee share rewards sustained activity by somebody else rather than a single qualifying trade, which makes it potentially larger and entirely dependent on how much that person trades.
The Tax Line Most Referral Pages Omit
Kalshi states that incentive credits, referral bonuses included, are reportable once they exceed 600 dollars in a calendar year.
That threshold will be irrelevant to most people collecting a single referral credit. It becomes very relevant to anybody treating referrals as a side income and sharing a link widely. Six hundred dollars of credits across a year is a reporting event, and it should be tracked as you go rather than reconstructed in April.
What You Are Actually Signing Up To
A bonus should not be the reason to open any account, and that goes double here, because a prediction market is not a brokerage.
Kalshi lets you trade contracts on the outcome of real-world events, which settle at a fixed value depending on whether the event happens. It operates as a federally regulated exchange, which distinguishes it from offshore betting sites, and that regulatory status is the main reason it has grown as fast as it has.
The risk profile is still its own thing. A contract that settles at zero is a total loss on that position, with no partial recovery and no long-term thesis that can rescue it. Markets on short-horizon events can be thinly traded, which widens spreads and makes exiting a position before settlement expensive. Treat position sizing accordingly.
If event contracts interest you on their own merits, the referral credit is a sensible thing to attach to an account you were opening anyway. If they do not, a credit that expires in seven days is a poor reason to start.
How to Claim It Without Losing It
- Open the referral link above before you create an account, so no 72-hour scramble is needed.
- Complete sign-up and identity verification. US residents only.
- Check the exact offer terms under Explore, menu, Your rewards, Offers. Read the amount and the deadlines there rather than trusting any figure from a referral page, this one included.
- Place a qualifying trade of at least 25 dollars on Predictions within 7 days of opening the account.
- When the credit lands, use it within 7 days. Set a reminder the day it arrives.
Frequently Asked Questions
How much is the Kalshi referral bonus?
Kalshi does not publish one fixed amount. Bonus values vary by offer and can differ between the referrer and the referee. The binding figure is in the offer attached to your account under Your rewards.
What does my friend have to do?
Open an account through the referral link, verify their identity, and trade at least 25 dollars on Predictions within 7 days of opening the account.
Can I add a referral code after signing up?
Only within 72 hours of creating the account, and only if no code is already attached. The clock runs from account creation, not from verification.
Can I withdraw the bonus credits?
Not necessarily straight away. Rewards may be issued as trading credits with withdrawal restrictions, and some require trading the credited amount on an eligible product first.
Do the credits expire?
Yes. Under the referral terms, bonus credit must be used within 7 days of being granted, and unused credit is forfeited.
Is a Kalshi referral bonus taxable?
Kalshi reports incentive credits, including referral bonuses, once they exceed 600 dollars in a calendar year.
The Bottom Line
The structure of Kalshi’s referral program is clear even though the amount is not. Both sides qualify independently, the new trader needs a 25 dollar trade on Predictions within 7 days, a code can only be attached within 72 hours of account creation, and the reward usually arrives as trading credit that expires 7 days after it is granted. Read the offer in your own account rather than any quoted figure, apply the link before you register rather than after, and treat the credit as a short-dated discount on trading you were doing anyway. On those terms it is worth having. As a reason to start trading event contracts, it is not.
