There is no single official Polymarket promo code. The codes you see advertised, usually named after the media site promoting them, unlock a new-user offer on Polymarket US, the CFTC-regulated app for Americans. In October 2026 the most common headline offer is about $25 in trading credit after a $10 deposit. The global site, polymarket.com, does not offer sign-up bonuses at all.
As of 23 October 2026. Promo codes are run through affiliate partners and change often, and we have not tested each one. The terms shown in the app when you sign up are the ones that apply.
Polymarket promo codes: what is on offer in October 2026
Partner sites such as sports and betting media publish codes in their own name (for example ROTOWIRE, CBSSPORTS or SIBONUS). The offer behind them has changed several times this year:
| Period | Headline offer advertised | Typical condition |
|---|---|---|
| Spring 2026 | $20 trading credit | Deposit $10 |
| Summer 2026 | Up to $50 credit at some partners | Deposit $20 and make a qualifying trade |
| October 2026 | $25 trading credit | Deposit $10 |
Two things follow from that table. First, the code itself matters less than the offer running when you sign up: most partners pass on the same deal. Second, if a site promises far more than the others (say $200 free), be suspicious: no Polymarket US offer we have seen in 2026 came close to that.
Who can use a Polymarket promo code
- New Polymarket US customers only. Offers are limited to one per person.
- Adults in an eligible state. The app checks your location; Polymarket US is available in most states, but some restrict sports contracts or the app as a whole (is Polymarket legal in the US?).
- Verified identity. You need to pass Polymarket US's identity check before any credit is released.
- Not on polymarket.com. The global site is a separate product that does not accept US users and has no promo codes.
How to claim a Polymarket promo code, step by step
- Download Polymarket US from the App Store or Google Play. Check the developer name; copycat apps exist.
- Start sign-up and enter the code in the promo or referral field. Most offers must be added during sign-up, not afterwards.
- Verify your identity. Credit is not released to unverified accounts.
- Make the qualifying deposit, usually $10, by debit card, Apple Pay or bank transfer (how to deposit on Polymarket).
- Trade if the offer requires it, then look for the credit in your balance or rewards screen.
If the credit does not appear after a few days, contact support from inside the app with your sign-up date and the code you used (Polymarket support).
What the credit is really worth
A promo credit is trading credit, not cash. You cannot withdraw it directly; you spend it on contracts, and what those contracts pay out becomes withdrawable money under the offer's terms. Credits often expire if unused.
On fairly priced contracts, a $25 credit is worth a little under $25 on average: Polymarket US charges takers a fee of up to $1.74 per 100 contracts at 50¢ (Polymarket fees explained). Spending it on long shots does not make it worth more; it only makes the outcome more random (how to calculate expected value).
The honest rule: a bonus is worth claiming if you were going to try Polymarket anyway. It is not a reason to deposit money you would not otherwise risk.
Promo code, referral code, invite code: what is the difference?
| Term | What it means in 2026 | Do you need one? |
|---|---|---|
| Promo code | A partner's code that unlocks the current new-user offer | No; optional |
| Referral code or link | Shared by an existing user; can reward both sides | No; optional |
| Invite code | A pass to skip the Polymarket US waitlist during its rollout | No; the waitlist is gone |
The waitlist story, and what to do if you still see one, is in do you still need a Polymarket invite code?
Polymarket US refer-a-friend
Existing Polymarket US users have their own invite link. Partner sites have reported the offer as $25 in credit for each side, up to $1,250 for 50 referrals, once the new user verifies and deposits. Treat those figures as reported: the invite screen in the app shows the current terms.
The global site: no sign-up bonus, but a referral program
Polymarket's global site rewards activity rather than sign-ups (Polymarket rewards explained). Its referral program, under terms that took effect on 28 May 2026, pays the referrer, not the new user:
- 10% of net trading fees from people you refer directly, 5% from people they refer.
- You need $10,000 in lifetime trading volume before rewards start, though you can share your link earlier.
- The new user must sign up within 30 days of clicking the link. Rewards stop after 30 days, or sooner if that user reaches the Platinum tier.
- Rewards are paid daily at midnight UTC in pUSD, Polymarket's dollar token. Nothing is earned on fee-free markets such as geopolitics.
Disclosure: if you live outside the US and plan to open a global Polymarket account anyway, you can use PredictDesk's referral link. It gives you no bonus and does not change your fees; Polymarket may pay us a share of the fees from your trades for your first 30 days.
Scams to avoid
- "Promo code generators" and codes for sale. Real codes are free and public.
- Anyone asking for your seed phrase or a wallet signature to "activate" a bonus.
- Fake support accounts offering credit in direct messages on X, Telegram or Discord.
- "Claim your airdrop" sites. Polymarket has no token; these are wallet drainers (Polymarket airdrop).
- "I just won $50,000" videos. In June 2026 the Wall Street Journal found that most of a sample of Polymarket influencer videos showed bets that were never placed (Polymarket fires its CMO).
Polymarket vs Kalshi bonuses
Kalshi also runs its sign-up offers through referral codes, paid as trading credit after you meet the requirements: $25 to $60 in October 2026 (Kalshi promo codes); the mechanics are in Kalshi sign-up bonus. If you are choosing between the two, the bonus is the least important difference: fees, markets and where each one is legal matter more (Kalshi vs Polymarket).
