What the sign-up bonus is

Polymarket US runs the offer as its Deposit Incentive Program, Campaign A, from October 16, 2026: deposit at least $10 in the 7-day window after onboarding and receive $25. Only the first deposit after onboarding counts, and each person may receive one incentive credit under the program.

What the credits do

The $25 arrives as promotional trading credits, shown in the Polymarket US App as Bonus. Your Cash is used first when you open a trade; if you have no Cash on the account, you can use the Bonus to open trades. When a trade using Bonus wins, the profit goes to your Cash balance and the Bonus you used comes back as Bonus.
