What Are Prediction Markets?

A prediction market lets you trade contracts tied to a future event. Each contract settles at $1 if the event happens and $0 if it does not, so the price (1¢ to 99¢) is a live, crowd-sourced read on the probability. Buy low, sell high, or hold to settlement.

Price equals probability

The core idea is simple: a contract trading at 60¢ means the market thinks the outcome is about 60% likely. As news breaks and money moves, the price updates instantly, which is why prediction-market prices often forecast outcomes more accurately than polls. On our Super Bowl odds page we convert live Kalshi prices into implied win probability for every team.

Frequently asked

What is a prediction market?

A prediction market lets people trade contracts tied to the outcome of a future event. Each contract settles at $1 if the event happens and $0 if it does not, so its live price (between 1¢ and 99¢) is the market's estimate of the probability.

How do prediction markets make money?

You profit by buying a contract for less than it eventually settles at, or by selling a position after its price rises. You trade against other participants, and the platform runs the marketplace rather than taking the other side of every bet.
