Polymarket US Bonus Code
A Polymarket US bonus code is entered during sign-up and links a new user to a Deposit Incentive Program campaign; code SPLASH links you to the campaign that gives $25 in trading credits for a first deposit of at least $10. A referral code is different: it is another user's username.

Where a bonus code goes
Polymarket US ties the campaign to the code or link used at onboarding, so the code has to be entered while you sign up. If no code is used, the campaign in effect when onboarding finishes applies instead. Referral codes must be applied during sign-up too.
