Polymarket referral code, promo code and bonus
There is no Polymarket bonus code. Polymarket doesn't run a sign-up bonus or promo code on polymarket.com, and the referral program we're in sets no discount for you. What we can give you is the rest: what our link actually does, what a trade costs, and whether Polymarket is open where you are.
Updated 27 Oct 2026 · fees, programs and country rules read from Polymarket's docs and regulators on 27 Oct 2026
Short version
- Bonus or promo code: none exists for polymarket.com.
- The $25 codes you've seen: Polymarket US offers, for US residents only, on a separate exchange. Where they come from.
- Our link: a referral link. You get nothing extra and pay the same fees. If you're new to Polymarket and sign up through it, DropSiren gets a share of the trading fees you pay.
- Fees: takers pay a fee on most markets ($1.25 on 100 sports shares at 50¢ at the docs' sports rate); makers pay nothing.
- What polymarket.com pays back: a taker rebate, from 3% of your taker fees once your 30-day weighted volume reaches $2,000. No link or code needed. The tiers.
- Countries: closed or close-only in a long list of places, the US and UK among them. Check yours.
- What it is: a prediction market, not a casino. 18+, and you can lose what you put in.
Polymarket links only show for visitors in countries where it's open to new trades.
When a Polymarket link shows here, it's an affiliate link. If you're new to Polymarket and sign up through it, DropSiren gets a share of the trading fees you pay. You get nothing extra: there's no sign-up bonus or promo code, and your fees are the same either way. 18+. Polymarket is a prediction market, not a casino. Prices move and you can lose what you put in.
Where the $25 codes come from
Search for a Polymarket promo code and you'll find US sites offering $25 for a code. Those offers are for Polymarket US, a separate exchange built for US residents and regulated by the CFTC, as its docs (docs.
Polymarket US's own terms also say the deposit credit doesn't need a code: you get the campaign tied to the code or link you sign up with or, if you use none, the campaign running when you finish signing up. Its new-user deposit program listed one campaign when we read them, Campaign A, so for a new account a code didn't change the amount. Its other credit campaigns that day depended on past deposits and trading.
Three things people mix up
Each read on the program's own page on 27 Oct 2026. Any of them can change without notice.
1 · Polymarket US only
Polymarket US promo and refer-a-friend credits
- Deposit credit
- Campaign A (from 16 Oct 2026): a new user whose first deposit is at least $10, made within 7 days of signing up, gets a $25 credit.
- Refer a friend
- A Polymarket US user shares their code, which is their username. When a new user signs up with it and deposits at least $10, both get $25, up to 50 referrals per user.
- What the credit is
- Promotional trading credit. It can open positions and pay fees, but it can't be withdrawn as cash.
- Outside the US
- Nothing. It's a different exchange from polymarket.com.

2 · polymarket.com
polymarket.com's own referral program
- Who earns
- The person who shares a market or profile link, and only once they've traded $10,000 in total on Polymarket.
- What they earn
- 10% of the net trading fees of people they refer, and 5% from the people those referrals bring in. Net fees are what Polymarket keeps after the new trader's own tier rebate.
- For how long
- Until 30 days after the new user signs up, or until they reach the Platinum tier, whichever comes first. The new user has to sign up within 30 days of clicking the link.
- For the new user
- Nothing. The docs describe no reward for the person who signs up.
- Source
- Polymarket's referral program docs (docs.
polymarket. com/ programs/ referral-program), read 27 Oct 2026. These terms have applied since 28 May 2026.
3 · DropSiren
Our affiliate link
- For you
- Nothing. Same prices and the same fees as going to polymarket.com yourself.
- For us
- 20% of the trading fees paid by new users who sign up through it and whose first deposit is $20 or more (Polymarket's affiliate program page on Dub Partners, read 27 Oct 2026).
- Where it shows
- Only where Polymarket is open to new trades. What the link does.
What our referral link does
Polymarket runs its affiliate program through Dub Partners, and DropSiren is in it. Our link carries our partner key in the address (the via tag). Here is all of it:
- For you: nothing. No bonus, no discount, no lower fees. Prices and fees are the same as going to polymarket.com yourself.
- For us: if you're a brand-new Polymarket user, the program pays DropSiren a share of the trading fees you go on to pay (the program page says 20%, read 27 Oct 2026). It only counts new accounts whose first deposit is $20 or more; existing accounts don't count. That's the program's rule, not a reason to put in more.
- What earns nothing: maker orders and markets with no taker fee pay us nothing, and we still show them.
- Where it shows: only for visitors whose country is open to new trades on Polymarket, after our list and Polymarket's own check both say so. Everyone else, search engines included, sees the prices without the link.
The fee numbers below come from Polymarket's own fee docs, which say takers pay a fee on most categories, and from the fee schedules on its live markets.
Polymarket fees, worked out
Polymarket's taker fee is shares × rate × price × (1 − price), rounded to five decimals, with the rate set by the market's category (Polymarket's fee docs (docs.
As a share of what you spend, the fee works out to rate × (1 − price), so it's heaviest on cheap shares. For 100 shares at the docs' sports rate of 0.05: at 10¢ the fee is $0.45 (4.5% of the trade), at 50¢ $1.25 (2.5%), at 90¢ $0.45 (0.5%). A live market's own schedule can be lower, or zero; the table under the calculator shows what the busiest markets carry right now.
On a big order we work the fee out at each price your order fills (our reading of Polymarket's fee docs; its order docs put a market buy's fee on top of the amount). For the games starting in the next 24 hours, with each order book: Polymarket max bet.
