What each official offer says
- Kalshi — official wording is $25 after a $25 trade. New U.S. users must finish identity verification and trade at least $25 on Predictions within 7 days of opening the account. Credits are not automatic, and unused bonus funds expire 7 days after they are granted.
- Polymarket US — official wording is a $25 trading credit for new customers. This invite has a usage cap, so the credit can run out. Confirm availability in official FAQs before you sign up.
- Kalshi Invest — official terms describe 10% off perps fees for 3 months after $50 notional volume within 7 days. This is a fee discount, not a cash grant, and it is separate from the Kalshi Predictions $25 offer.
Investing involves risk, including loss of principal. Nothing on this page is investment advice. Event contracts and perpetual futures can be volatile and may use leverage.
Official terms win if anything differs. Confirm the live offer in each app or site before you trade.
