Polymarket rate read from the catalog for sports_fees_v3 (19,255 markets in a sample of 20,000 rows drawn from 12,959,143 in the archive). Kalshi's rate is its published general schedule; the PDF has been rate-limiting fetches, so it is documented rather than verified.

Exchange-side taker fees per each venue's published formula (rate × contracts × price × (1 − price)); contracts = stake ÷ price, rounded down to whole contracts. Fees peak at 50¢ and shrink toward the extremes. Most quoted cross-venue “arbs” are negative-EV after these fees; the taker-fee breakeven on a Kalshi/Polymarket pair is roughly 3.5–4¢.
