Prediction Market
A prediction market lets people trade contracts on the outcome of future events, with prices reflecting the crowd's odds.
What it means
A prediction market is an exchange where users buy and sell contracts tied to whether an event happens - an election, a game result, an economic number. The contract's price, usually between 0 and 1, reads as the market's implied probability. It's peer-to-peer: you trade against other users, not against a house setting the line. That's the core difference from a fixed-odds sportsbook, where the operator prices the market and carries the risk against its own house edge.
Why it matters for operators
Regulated event-contract exchanges like Kalshi, plus crypto-based markets like Polymarket, increasingly list contracts on sports and outcomes that overlap with sportsbook products. Because they run on trading fees rather than a bookmaker margin, their pricing can look sharper to informed users, which creates a real player-migration question for operators. The regulatory status of these markets - traded under financial rules rather than gaming licences in some jurisdictions - is one of the open fault lines of 2026.
Example
Instead of taking sportsbook odds of -110 on a team, a user buys "yes" contracts at 0.52 on an exchange and can sell them mid-event as the price moves - closer to trading a stock than placing a bet.
