Compare
369X, Polymarket and Kalshi, side by side.
Polymarket and Kalshi are the two largest prediction markets and both run order books. 369X’s design differs on pricing (an LMSR market maker), market creation (user requests with a creator fee) and leverage on outcomes. 369X is launching on testnet; the others are live at scale, and that gap matters.

- Liquidity and track record. Deep order books on major events, years of resolved markets and established brands.
How this comparison was made
- Competitor cells come from each venue’s own help centre or documentation, read on the check date. News reporting is used only where noted.
- Where the sources checked say nothing, the cell says “not documented in the sources checked”, not “no”.
- Polymarket’s international platform and its separate US venue are different products; the table describes the international platform unless stated.
- PredictIt is not in the table because its current terms couldn’t be confirmed from a primary source on the check date.
- Fees change often. Check the linked pages before relying on a number.
