In the US app, a Polymarket referral code is just another user's username: you deposit $10 and you both get $25 in trading credits. The international site runs a different program that pays the referrer a share of fees.
A Polymarket referral code is simply another Polymarket US user’s username. If you enter it when you sign up and deposit at least $10, you and the friend who referred you each get $25 in trading credits, per Polymarket US’s official program terms as of October 2026. There’s no secret code to hunt for, and we don’t publish codes. The rest of this page explains how Polymarket’s two separate referral programs work.
Polymarket now runs as two separate products, and its own help centre says the accounts “are not connected”:
The two run different referral programs. US users get a sign-up credit. International users who refer others get a share of their fees.
Polymarket US’s Refer-A-Friend program, as described in its docs and the exchange notice it filed on August 26, 2026, works like this:
The fine print that matters:
You don’t need a referral code to get a sign-up credit. Polymarket US also runs a Deposit Incentive Program. Its current campaign, running from October 16, 2026, gives you $25 in credits if you deposit at least $10 within seven days of onboarding. Only your first deposit counts, and the credit arrives within 24 hours.
You can’t stack the two: referred users “may not participate in the Deposit Incentive Program,” per the exchange notice. So the $25 is the same either way. The difference is that a referral code also earns your friend $25.
| Your situation | Best route | What you get | What your friend gets |
|---|---|---|---|
| A friend already uses Polymarket US | Their username as a referral code | $25 credit | $25 credit |
| You don’t know anyone on it | Deposit Incentive Program (no code) | $25 credit | — |
| You plan to deposit $1,000+ | Check the app for the Deposit and Trading Incentive Program | Credits of $10 to $250, depending on your activity and the campaign | — |
| You’re outside the US, on polymarket.com | Nothing to claim | No sign-up bonus | Possible fee share (see below) |
Every route depends on passing identity verification. Polymarket US asks for your legal name, date of birth, phone number, home address and Social Security number before you can deposit. Its participant agreement requires you to be at least 18 and of legal age in your state.
On polymarket.com there’s no referral code. You share any market or profile page and anyone who signs up within 30 days of clicking it becomes your referral. Under terms that took effect on May 28, 2026, the referrer earns:
Referrals trading in fee-free markets, including geopolitics and world events, earn you nothing. Polymarket’s docs don’t mention any bonus for the person being referred. Older articles quoting a 30% revenue share describe the previous terms.
Polymarket US’s App Store listing says it is “fully legal & CFTC regulated in the United States — in all 50 states*”, with the footnote “Trading currently unavailable in NV.” A Nevada state court enjoined Polymarket on May 29, 2026, per the Nevada Gaming Control Board. On September 24, 2026, New York’s Attorney General sued Polymarket US, calling it an “illegal, unlicensed gambling operation.” Rules are changing quickly, so check our prediction market legality tracker before depositing.
Both US exchanges give new users promotional credits rather than cash. See how Kalshi’s version works in our Kalshi promo code guide. To compare the platforms on fees, markets and funding, read our Polymarket vs Kalshi comparison and our full Polymarket review.
On Polymarket US, the referral code is simply the referring user's username. A new user enters it at sign-up, deposits at least $10, and both people get $25 in promotional trading credits within seven days. On the international polymarket.com site there is no code: referrals come from a shared market or profile link.
No. Polymarket US says its incentive credits 'may be used to open positions and pay applicable fees, but may not be withdrawn as cash.' Since September 10, 2026, refer-a-friend credits also expire a set number of days after they're issued.
No. Polymarket US's exchange notice for the amended Refer-A-Friend program says referred participants may not take part in the Deposit Incentive Program. You get one $25 credit or the other, not both.
Polymarket US's App Store listing says trading is available in all 50 states except Nevada, where a state court enjoined it in May 2026. New York sued Polymarket US in September 2026 and Ohio has sent a cease-and-desist, so check the app's location check and our legality tracker first.
