What Is a Prediction Market?
If a share for "Arsenal beats Chelsea" trades at $0.65, the market is saying there's roughly a 65% chance Arsenal wins. If you think Arsenal's odds are higher than 65%, you buy YES. If you think they're lower, you buy NO. Prices move continuously as new information arrives.
How prediction-market prices work
Think of every market as having two sides:
- YES — the event will happen.
- NO — the event won't happen.
YES + NO always sum to $1. If YES is $0.65, NO is $0.35. Buy 100 YES shares at $0.65 = you spent $65. If the event happens, you get $100 back ($35 profit). If it doesn't, you get $0.
Some markets are 3-way (Home / Draw / Away in football). All outcomes still sum to $1 between them.
Why prediction markets exist
Three main reasons people trade them:
- Information. Prices reveal real consensus probabilities, often more accurately than polls or expert forecasts. The "wisdom of the betting crowd" outperforms most pundits.
- Hedging. If you depend on a real-world outcome (a small business owner exposed to election results, a sports bettor with team merchandise inventory), you can hedge.
- Trading edge. If you have superior knowledge or analysis, you can profit by trading where the market price is wrong.
How prediction markets resolve
Different platforms use different mechanisms:
- Polymarket: UMA optimistic oracle. Humans propose an outcome; anyone can dispute within a window; consensus settles.
- Kalshi: Their internal team reads sources and settles, audited under CFTC oversight.
- BlockForecast: Multi-agent AI consensus. Multiple independent AI agents read authoritative sources, vote with confidence scores, reach agreement automatically. See how it works.
Are prediction markets gambling?
Legally and structurally, prediction markets are not the same as sports betting:
- House edge: Sportsbooks set the odds against you (the "vig"). Prediction markets set prices through trading — the platform itself isn't a counterparty in the same way.
- Information markets: Prediction markets are designed for price discovery. Sportsbooks are designed for entertainment betting.
- Settlement: Prediction markets resolve to public, verifiable facts. Sportsbooks settle on a private bookmaker's reading of those facts.
- Regulation: In the US, Kalshi is CFTC-regulated as a "Designated Contract Market" — explicitly NOT classified as gambling. Polymarket and BlockForecast operate as decentralized markets on crypto rails. Full legal breakdown.
Practically: many people use prediction markets the way they'd use a sportsbook. The mechanism is different, the experience is similar, the regulatory framing varies.
