Kalshi odds converter: cents to American odds, after fees
Type a Kalshi or Polymarket price to see it as sportsbook odds, with and without the trading fee. The chart below lists every price from 1¢ to 99¢.
How the conversion works
Every contract pays $1 if it wins, so the price is what you risk and $1 minus the price is what you win. Decimal odds are 100 ÷ cents. American odds follow from decimal: +(decimal − 1) × 100 for underdogs, −100 ÷ (decimal − 1) for favorites.
Kalshi also charges a fee on each contract: 0.07 × price × (1 − price), rounded up per order. It is biggest at 50¢ (1.75¢) and tiny near the ends, so a 50¢ price is really about −107, not even money.

Kalshi odds questions
How do you convert Kalshi prices to American odds?
Divide 100 by the price in cents for decimal odds, then convert: at 2.00 or more, American = (decimal − 1) × 100; under 2.00, American = −100 ÷ (decimal − 1). So 40¢ is 2.50, or +150, and 60¢ is 1.67, or −150. For the honest number, add Kalshi’s fee to the price before you divide.
What are 50 cent odds on Kalshi?
50¢ is +100 before fees and -107 after Kalshi’s fee. A 50¢ contract is an even-money bet before fees; the fee (1.75¢ per contract) makes it about the same as a sportsbook’s −107.
What does 70 cents mean on Kalshi?
70¢ is -233 before fees and -251 after Kalshi’s fee. You risk 70¢ to win 30¢ per contract, and the market gives the outcome about a 70% chance.
What does 25 cents mean on Kalshi?
25¢ is +300 before fees and +280 after Kalshi’s fee. You risk 25¢ to win 75¢ per contract, and the market gives the outcome about a 25% chance.
Is the Kalshi price the probability?
Roughly. A 63¢ contract means traders price the outcome at about 63%. The fee and the bid-ask spread mean the price you pay is a little above the market’s true estimate, the same way a sportsbook’s odds carry a margin.
Does Polymarket convert the same way?
Yes. Polymarket prices are also cents per $1 contract, with a fee of 0.0695 × price × (1 − price). The chart below has a Polymarket after-fee column next to Kalshi’s.
