Prediction-market prop firm

A proprietary-trading firm that funds traders to trade prediction markets such as Polymarket and Kalshi, taking a share of the profit.

A prediction-market prop firm applies the proprietary-trading challenge model — long established in forex and futures — to binary event markets. You pay for an evaluation (or, with instant funding, skip straight to a funded account), prove you can hit a profit target within risk limits, then trade the firm's capital and keep a share of the profit, usually 70 to 90 percent.

The category is new: most firms launched in 2026, and pricing, rules and even whether execution is real or simulated still vary widely. Almost all of them run a simulated account priced off the live market rather than putting your own capital on-chain.
