Counted from the last verified snapshot of 225 outcomes priced above 2% on both venues, 09 Nov 2026, 01:29 UTC. A lower YES percentage is the cheaper side of the same contract, so the same $100 buys more of it. This is one moment, not a running record, and it does not predict which venue will be cheaper on the next contract you look at.
| Cheaper venue | Outcomes | Share |
|---|---|---|
| Kalshi | 93 | 41% |
| Polymarket | 91 | 40% |
| Same price | 41 | 18% |
The average gap between the two venues on the same outcome is 1.4 percentage points. Where the gap is wide, the same stake buys materially more contracts on one side than the other.

| Toronto Maple Leafs to win Toronto Maple Leafs vs New Jersey Devils | Toronto Maple Leafs vs New Jersey Devils | Polymarket | 29% | 15.0 pts |

A further 204 outcomes were left out of that count because one venue quoted them below 2%. Both venues support fractional-cent prices. These long shots remain available in the individual comparisons, where the lowest verified YES ask determines the cheaper venue.
A wide gap on two contracts that settle identically is rarely free money. It usually means one side is thinly traded, so the quote moves the moment anyone acts on it. Check the available price and trading volume before acting on a difference.
Both venues can charge trading fees. Polymarket charges taker fees on fee-enabled markets; other markets are fee-free. Every price on this site is the quoted cost to buy YES before fees. A lower quoted price does not necessarily mean a lower total cost after fees.
We do not model venue fees or guarantee that a full $100 position can fill at the displayed quote. Check the current Kalshi fee schedule and Polymarket fee documentation for the market you intend to trade.
We price Kalshi and Polymarket, and we only pair two contracts after reading both venues' resolution rules and confirming they settle the same question. Robinhood, DraftKings Predictions and FanDuel Predicts are not priced here yet, so no number on this site claims to represent them. Prices are shown as the market's percent chance and show the cost to buy YES at the stated update time, before venue fees.
