A prediction market is a market system where participants trade views on future outcomes. An event contract is a specific financial instrument listed within that system. The market provides price discovery, access, and rules; each contract defines a question, its outcomes, timing, source, payout, and settlement process.
The simplest distinction
Think of a stock exchange and a listed stock: the trading venue and the trading instrument are related but not the same. Similarly, a prediction market may list many event contracts, while an event contract can be described without referring to every feature of the venue that lists it.
| Aspect | Event contract | Prediction market |
|---|---|---|
| Unit of analysis | One contract tied to one outcome | The venue or system listing contracts |
| What defines it | Question, outcomes, expiration time, source, payout | Listing infrastructure, trading, custody, oversight, settlement |
| User’s key question | “Exactly what pays out?” | “Where can I trade this, and under what rules?” |
| Main failure mode | Ambiguous or disputed contract terms | Weak liquidity, poor access, custody, governance, or oversight |
Why the terms are often used interchangeably
Event contracts are the main tradable building blocks of prediction markets, so product pages and public discussions often use the terms interchangeably. CFTC educational material discusses them together and explains the common binary, multiple-choice, and range structures.
The distinction matters during due diligence. A reputable platform cannot rescue a poorly written contract, and a correct contract by itself does not prove that a platform has liquidity, legality, or reliable operations.
Event contracts vs. forecasts and surveys
An event contract creates a financial payout. A forecast is an estimate, and a survey is a sample of stated opinions. Prices in a prediction market can act as a forecasting signal, but that signal comes from the trading mechanism and contract design.
