Markets that price beliefs about the future.
Unlike a traditional sportsbook, prediction markets aggregate many traders. When a “Yes” share trades near $0.72, the market is roughly implying a 72% chance the event happens — subject to fees, spreads and liquidity.
How prediction markets work
You buy outcome shares (Yes/No or multi-outcome). If you are right at resolution, shares settle to $1 (or the platform’s settlement unit). If you are wrong, they settle to $0. Between those points, you can usually sell early if the price moves.
- Event markets — elections, crypto milestones, sports results, macro data.
- Resolution rules — who decides the outcome and from which source.
- Liquidity — thin markets can have wide spreads even when the “headline price” looks clean.
- Access model — regulated KYC accounts (Kalshi) vs wallet-native crypto venues (Polymarket, Azuro).
Prediction market vs sportsbook
A sportsbook sets odds and takes the other side. A prediction market is closer to an exchange of beliefs: other traders are your counterparties. That means better discovery on long-tail events — and more responsibility to read rules, spreads and custody risk.
Main platform types in 2026
- Polymarket — crypto-native public-event discovery benchmark.
- Kalshi — US-regulated event contracts; often the cleaner US start.
- Manifold — community / play-money practice layer.
- On-chain venues — Azuro, Omen, Seer and protocol-native markets.

FAQ
Are prediction markets gambling?
They can involve financial loss and are regulated differently by country. Some products are event contracts; others look closer to betting. Always check local rules — GammaPredict is not legal advice.
How accurate are prediction market prices?
Prices reflect traded beliefs under current liquidity. They can be informative, but spreads, fees, manipulation risk and thin markets all matter.
