Polymarket tools

Calculators that run in your browser. No wallet connect, no order ticket, no ClickHouse on the request path. Polydata never executes trades.

• Odds converter

  Contract ¢ ↔ implied probability ↔ American odds ↔ decimal odds. Built for “Polymarket odds to probability” lookups.

• Payout calculator

  YES or NO, buy price, and stake → contracts, win payout, profit, ROI. No winner fee on Polymarket.
