How Do Prediction Markets Work? Shares, Odds & Payouts
A mechanics-focused guide to how prediction markets price probability, pay out, and let you trade in and out of positions.
If you have ever wondered how prediction markets work under the hood, this guide breaks down the mechanics: shares, pricing, implied probability and payouts.
Shares and price
Every market has two sides: Yes and No. A share pays $1 if its side wins and $0 if it loses. The current price is what the market charges for that potential $1 payout. A Yes price of $0.40 implies a 40% probability and a potential 2.5x return if Yes resolves true.
Implied probability
Price equals probability. This is the core idea: a market trading at $0.75 is telling you the crowd believes there is a 75% chance the event happens. As news breaks, traders buy or sell and the price—and therefore the probability—updates instantly.
Payouts and exiting early
You do not have to wait for resolution. If you bought Yes at $0.40 and it climbs to $0.70, you can sell to lock in profit before the event even happens. At resolution, winning shares settle at $1.
Reading the odds
| Price | Implied probability | Payout if it wins |
|---|---|---|
| $0.20 | 20% | 5.0x |
| $0.50 | 50% | 2.0x |
| $0.80 | 80% | 1.25x |

FAQ
What happens if I am right?
Your winning shares each settle at $1. Your profit is $1 minus what you paid per share.
