How this is matched
Multi-outcome markets are matched outcome by outcome by name, with an alias table for the usual spellings. Polymarket prices come from its live order book, Kalshi from its public API. Refreshed every 45 seconds.
What this is not
Read-only. Nothing here places or routes orders and nothing is advice. Fees, slippage and the time it takes to move money between venues are not in these numbers.
