Event contracts vs. prediction markets: What’s the difference?
A prediction market is a market or system; an event contract is an individual instrument tied to one outcome. This distinction helps clarify pricing, rules, and regulation.
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. Likewise, a prediction market can 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 that lists contracts |
| Definition | Question, outcomes, cutoff time, source, payout | Listing, trading, custody, oversight, settlement infrastructure |
| User’s key question | “What exactly pays out?” | “Where can I trade this and under what rules?” |
| Main failure mode | Ambiguous or disputable contract terms | Weak liquidity, access, custody, governance, or oversight |
Why these 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-based structures.
The distinction matters most during due diligence. A reputable platform cannot rescue a poorly written contract, and a precise 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 prediction markets can act as a forecasting signal, but that signal comes from trading mechanics and contract design.

Read [What is a prediction market?](/articles/what-is-a-prediction-market/) when you need to understand the venue, price aggregation, and forecasting. Use the [platform evaluation framework](/articles/how-to-evaluate-an-event-contract-platform/) before comparing operators.
