Why people look for an alternative to Polymarket

polymarket.com is closed to US residents — no deposits and no new trades. US residents are sent to Polymarket US, a separate app run by a different company.
Outside the US, access varies by place: the UK is close-only (you can close positions but not open them) and four Canadian provinces are restricted.
It settles in USDC on-chain, so you need a crypto wallet and a stablecoin on-ramp — something a dollar exchange does not ask of you.
Taker fees apply on selected categories and scale with price × (1 − price), so the cost of a trade depends on the market you are in.
