The $25 deposit offer
Polymarket US documents a “deposit incentive” in its user programs: deposit $10 or more and get $25 in promo credit. The catch is in the eligibility line. You have to be presented the campaign through an onboarding code or link, so it depends on how you arrive at the sign-up page. We don’t have a Polymarket code of our own.
Refer a friend
If someone you know already uses Polymarket US, their referral link is the simplest route. When you deposit $10 or more, you both get $25. Each user can refer up to 50 people, and credit is added within 7 days.
Deposit and trade campaigns
Polymarket also runs campaigns that pay credit each day for 5 days after a deposit: $5 a day for a $50 deposit, up to $50 a day for a $500 deposit. Only trades priced between 10¢ and 90¢ count, which stops people collecting credit on near-certain outcomes.
What promo credit is worth
Promo credit can be traded but never withdrawn, so $25 of credit is worth whatever you win with it. Bought at 50¢, $25 of credit gets you 50 contracts that pay $50 if you’re right and nothing if you’re wrong. The fee on that trade is about $0.87, charged at Polymarket’s taker rate of 0.0695.
