What this bet really costs you
| Venue | Fee per contract | Total taker fee |
|---|---|---|
| Kalshi | 1.71¢ | $1.71 |
| Polymarket US | 1.46¢ | $1.46 |
Exchange-side taker fees per each venue's published formula (rate × contracts × price × (1 − price), Kalshi rounds the order total up to the next cent). 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¢.
