Whalidate

Copy trading for Polymarket. Whalidate scores whale wallets on how they made their money (return, settled trades, worst drawdown and how much of the profit came from one trade) and copies only the new trades that pass your rules: entry price band, slippage cap, market categories and loss limits. Every strategy runs free on paper first; live trading is a paid plan from $49/month with no per-trade fee.

Catalyst

Catalyst runs a prediction market trading challenge. Pick a challenge from $10 and trade live Polymarket events on sports, politics, crypto and more in a simulated account, so you have no market exposure. Each challenge shows its profit target, payout and rules before you pay. Pass the challenge and get paid up to $3,000, straight to your Catalyst wallet, ready to withdraw. You keep 100%. Catalyst also runs free prediction competitions with cash prizes.

outcometick

outcometick sells historical tick data for the crypto Up/Down markets on Polymarket (BTC, ETH, SOL, XRP, DOGE, BNB, HYPE) and Predict.fun (BTC, ETH, BNB), archived since June 2026. It carries the Chainlink streams these markets settle on (with the TWAP streams on Polymarket), plus order books, Polymarket trade prints and each market's strike and outcome, so results can be recomputed. Files are checksummed, downloaded by API. A hosted sandbox runs Python or Node.js strategies on the same data.
