What Is an Event Contract? Prediction Market Instruments Explained
An event contract is a financial instrument that pays out based on whether a specific real-world event occurs. They are the building blocks of prediction markets.
Definition
An event contract is a derivative instrument that pays a fixed amount if a specified event occurs, and nothing (or a different fixed amount) if it does not. Event contracts are the fundamental building blocks of prediction markets.
Event Contracts vs. Options
Event contracts share similarities with binary options, but differ in important ways:
| Feature | Event Contract | Binary Option |
|---|---|---|
| Outcome | Real-world event | Price of an asset |
| Settlement | $0 or $1 | $0 or $1 |
| Trading | Two-sided exchange | Against a broker |
| Regulation | CFTC-regulated (US) | Often unregulated |
CFTC Recognition
In the United States, the CFTC has classified certain event contracts as regulated derivatives. Platforms like Kalshi operate under CFTC oversight, offering event contracts on economic data, weather, and elections.
On-Chain Event Contracts
Crypto prediction markets implement event contracts as tokens on a blockchain. Each token represents one share of an outcome. Smart contracts handle settlement automatically when the event resolves.
On Purrdict, event contracts are HIP-4 tokens on Hyperliquid, inheriting the performance and security of the Hyperliquid L1.
