Research every PolyMarket bet without leaving the page

Everything you'd normally open ten tabs for

On-chain signals
Your position, top holders, the leaderboard, recent trades and order book, plus related and trending markets, all in one panel.
Trading tools
A Kelly criterion calculator, a whale tracker, and a NegRisk arbitrage detector, built for PolyMarket's specific mechanics.
Free to use, $9.99/month to remove the limits
Every tab works for free. Pro unlocks full feeds, cross-market consensus, and the trading tools. Start with a 7-day free trial.
