Prediction Market
A prediction market is a marketplace where participants trade contracts tied to the outcome of a real-world event, and each contract's price reflects the crowd's implied probability that the event will happen.

Explained Simply
In a prediction market, a contract on a yes/no question — will inflation come in above 3% this month, will a given team win — trades between roughly $0.00 and $1.00. That price maps directly to a probability: a contract at $0.62 implies the market collectively believes there is about a 62% chance the event occurs. Because prices update continuously as new information arrives, prediction markets behave like live, crowd-sourced forecasts. Platforms like Kalshi operate regulated, exchange-style prediction markets in the United States.
How Prices Map to Probability
A prediction-market contract pays a fixed amount (typically $1) if the event resolves 'yes' and $0 if it resolves 'no'. Because of that fixed payout, the price you pay is itself an estimate of probability: a $0.30 contract implies roughly a 30% chance. As the event nears its resolution, prices tend to converge toward $1.00 or $0.00.
A price is a market estimate, not a certainty. Crowds can be wrong, thin markets can misprice, and an implied 30% event still happens roughly three times in ten. Treat the number as a probability, not a promise.
Prediction Markets vs. Traditional Betting
Unlike a fixed-odds sportsbook, a prediction market runs on a two-sided order book: you trade against other participants rather than against the house, and you can often exit a position before the event resolves by selling your contract at the current price. Regulated venues like Kalshi list defined questions with a stated resolution source and deadline.
As with any market, prices move against you, fees apply, and you can lose the full amount you put in — so position size and risk matter.
Frequently Asked Questions
How does a prediction-market price show probability?
Because a contract pays about $1 if the event happens and $0 if it does not, its price sits between them and approximates the market's implied probability. A contract trading at $0.45 implies roughly a 45% chance the event occurs.
Are prediction markets the same as gambling?
They share features with betting, but regulated prediction markets are exchange-style venues where prices act as forecasts and you trade against other participants. They still carry real risk of loss, and this glossary is educational rather than a suggestion to trade.
Can I sell a contract before the event resolves?
Usually yes. Because prediction markets use an order book, you can typically close a position early by selling at the prevailing price, subject to available liquidity and fees, rather than waiting for settlement.
How Tradewink Uses Prediction Market
Tradewink Predictions treats prediction-market prices as a probability feed. We compare a market's implied probability against our own model estimate to surface markets where the price may diverge from a calibrated forecast. This is educational analysis of pricing, not a recommendation to place any trade.
