Prediction Markets Explained: How They Work in 2026
Published 2026-06-15 · Last reviewed 2026-06-15
TL;DR
- A prediction market lets you buy and sell shares in the outcome of a future event.
- The price of a share equals the market's implied probability — $0.40 means a 40% chance.
- Because real money is at stake, prices aggregate information better than polls or pundits.
Prediction markets let you put money on what will happen — and the price you pay tells you exactly what the crowd thinks the odds are. They power everything from election forecasts to the college markets we track on this site.
The core idea
Every market is a question with a clear resolution: "Will Team X win the title?" You buy "Yes" or "No" shares. If you're right, each share pays out $1. If you're wrong, it pays $0. The price you pay to buy a share is the market's estimate of the probability.
Price equals probability
This is the whole trick. A "Yes" share at $0.30 means the market prices a 30% chance. If new information makes the event more likely, buyers push the price up toward $1. That live price is the single most useful number a prediction market produces.
Why they're often more accurate than polls
Polls ask people what they think; markets make people back it with money. A trader who spots mispricing has a profit incentive to correct it, so prices absorb news within minutes. Across many events, this crowd-sourced estimate tends to beat individual pundits.

Frequently asked questions
What is a prediction market?
A prediction market is an exchange where you trade shares tied to the outcome of a real-world event — an election, a game, an award. Shares pay out $1 if the outcome happens and $0 if it doesn't.
How do prediction market prices work?
A share's price is the market's implied probability. A 'Yes' share trading at $0.65 means the market thinks there's a 65% chance the event happens. Prices move as traders buy and sell.
Are prediction markets accurate?
Often more accurate than polls or single experts, because traders risk real money and update prices instantly on new information. They're not perfect — thin markets and surprises still cause misses.
Are prediction markets legal in the US?
Kalshi is a CFTC-regulated US exchange and legal in most states. Polymarket restricts US users on paper. Rebet is a mobile app available in 40 states plus D.C. Always check your state.
