An event contract is a tradable contract that pays a fixed amount if a defined future event happens and nothing if it does not.

An event contract ties a payout to a clear yes or no question about the future. If the event happens as defined, the contract resolves yes and pays its full value, usually one dollar. If it does not, the contract resolves no and expires worthless. Because the payout is capped at one dollar, the price before resolution sits between one and ninety nine cents and reads as the market implied probability of the event.
In the United States, event contracts are treated as derivatives and trade on exchanges registered with the Commodity Futures Trading Commission. The regulator describes them as instruments that can be used to hedge economic risk or to speculate on outcomes, with their value derived from the outcome of an underlying event rather than from a traditional commodity price.
The structure is what separates an event contract from a casual wager. The event is defined, the payout is fixed, and the way the result is measured is written into the contract terms before trading. On an exchange there is typically no house taking the other side. You trade against other participants, and the venue earns from fees.
Event contracts cover many categories, from economic releases to other measurable public outcomes. Whatever the topic, the same logic applies. A price is a probability estimate, not a forecast, and the contract can resolve against you, so the risk of loss is real.
Suppose a contract asks whether a defined figure will land above a stated threshold by a set date. It trades at thirty cents. That price implies the market is pricing roughly a thirty percent chance of yes.
If the figure clears the threshold, the contract resolves yes and pays one dollar, so a buyer at thirty cents gains seventy cents before fees. If it does not, the contract resolves no and the buyer loses the thirty cents paid. The result is binary, and fees reduce the net either way.
Understanding how these markets work does not make trading safe. Prediction markets can lose you money, and a confident price can still be wrong. Stake only what you can afford to lose, never to chase a loss, and never on borrowed money. If it stops feeling like a free choice, step back.
