Cents into odds
A 55-cent contract becomes an American price you can compare with any sportsbook, so the exchange is just one more book on the line.
Exchanges and prediction markets
Exchange prices as real legs, net of fees.
Prediction markets and exchanges quote cents, not odds, and they charge fees. We turn every quote into the price you actually pay after the fee, and line it up against the books.
What it finds
The fee taken out
Every exchange price is shown after the venue's fee, the same way our +EV, arb and middles boards price it.
Depth beside price
Where the exchange shows how much is on offer, we show it, so you know whether a price holds at your size.
One contract, before and after the fee
Illustration, not a live betQuoteYES at 55¢
Fee2¢ on a one-contract order
Before fee-122
After fee-133
- 55¢ for a $1 payout is the same as -122 at a sportsbook.
- The taker fee is 0.07 × 0.55 × 0.45 = 1.7¢. Kalshi rounds the fee up per order, so a one-contract order pays 2¢ and costs 57¢ all in. Bigger orders round once, so the fee per contract runs closer to 1.7¢.
- 57¢ for $1 is -133. That is the number to compare with the books.
Eleven cents of price vanish into the fee. A quote that looks best before fees can be the worst after them.
Before you bet it
- You are comparing the after-fee price.
- There is enough on offer at that price for your stake.
