Is Polymarket Legal in the US?
Polymarket is currently legal in 48 U.S. states plus Washington, D.C., with Nevada and Minnesota excluded. Because prediction markets remain subject to changing regulations, availability and platform features may change over time.
To use Polymarket, you must be 18 or older, have an eligible U.S. address, and complete the required identity verification. Check the latest Polymarket terms before depositing or trading.
How Does the Polymarket Refer a Friend Program Work?
The Polymarket refer a friend program allows eligible traders to earn a percentage of trading fees generated by their referrals. You must have at least $10,000 in lifetime trading volume before you can participate.
After qualifying, create your referral link through Polymarket’s Refer and Earn feature and share it with new traders. The current boosted program pays 30% of fees from direct referrals and 10% from indirect referrals. Referral rewards apply to eligible trading activity during the referred user’s first 180 days.
Example: if someone you refer invites another trader, you can also earn a share of the fees generated by that second-level referral. Rewards currently apply to eligible trading activity during the referred user’s first 180 days.
The referral program is based on trading fees, not a fixed cash bonus, and Polymarket’s fee rates vary by market. Always check the latest program terms because referral percentages, eligibility requirements, fee rates, and reward periods can change.
