How to read Kalshi odds
The single most important thing to understand about Kalshi is that the price is the probability. A contract trading at 63 cents is the market's way of saying it thinks there is about a 63 percent chance the event happens. Once that clicks, every market on the exchange becomes readable at a glance.
This guide walks through reading a single market, what the yes and no sides cost, how to read a whole field of outcomes, and the handful of misreadings that quietly cost beginners money.
- Kalshi contracts settle at either $1 or $0: a dollar if the event happens, nothing if it does not.
- Every market has two sides.
- Many Kalshi events have more than two outcomes, like an election with several candidates or a championship with many teams.
- The first is treating a 90-cent favorite as a sure thing.
The price is the probability
Kalshi contracts settle at either $1 or $0: a dollar if the event happens, nothing if it does not. So a contract's price in cents is simply the market's implied probability in percent. Sixty-three cents means about a 63 percent chance. Five cents means a long shot the market gives roughly a 5 percent chance. Ninety-five cents means a near-certainty.
This is why disciplined traders never think in terms of raw dollars won or lost. They think in terms of edge: do I believe the true chance is meaningfully different from the price? If you think an event is 75 percent likely and it trades at 60 cents, that gap is your edge. If you have no view different from the price, there is no trade.
Yes and no, and what each costs
Every market has two sides. Buying yes at 63 cents risks 63 to make 37 if the event happens. Buying no on the same market costs about 37 cents, risking 37 to make 63 if it does not. The two prices are mirror images: yes plus no is roughly a dollar, with the small gap being the spread and the exchange's edge.
Reading this correctly matters because the cheaper side is not automatically the better bet. A 12-cent no is only good value if the true chance of yes is below 12 percent. Price tells you what you pay; your own estimate of the probability tells you whether it is worth paying.
Reading a whole field
Many Kalshi events have more than two outcomes, like an election with several candidates or a championship with many teams. In a one-winner event exactly one outcome can happen, so the fair prices of all outcomes should add up to about 100 cents. If buying yes on every outcome would cost 106 cents, that 6 cents is the overround, the market's built-in margin.
Be careful not to confuse a one-winner event with a multi-select event, where several outcomes can each happen independently. In a multi-select event the prices can sum well above 100 percent and that is completely normal, not a mispricing. Our odds boards label which kind you are looking at so the sum reads correctly.
Common misreadings
The first is treating a 90-cent favorite as a sure thing. Nine times in ten it pays, but the tenth time it does not, and paying 90 cents to make 10 means a single loss erases many wins. High prices are high probabilities, not guarantees.
The second is reading a price near 1 or 99 cents as a live opportunity. Those outcomes have effectively already happened; there is rarely any edge in trading them. The third is ignoring fees: the taker fee is largest near 50 cents, so a coin-flip market you trade often can bleed money even when your reads are fine. Read the price as a probability, compare it to your own estimate, and account for the fee, and you are reading Kalshi odds the way a sharp does.
