Event Contracts FAQ
What Are Event Contracts? Event contracts are a derivative product launched by OKX. Each contract is defined using natural language to describe a specific event, and user payouts are determined by the final outcome of that event. Each event contract pair represents a contract with a potential payout of 1 USDT. Users simply assess the likely outcome and select a direction, then purchase contract shares in the corresponding direction.Published on 16 Apr 2026Updated on 6 May 2026FAQWhat Are Event Contracts
The current price reflects the market's collective judgment of the probability of the event occurring. At expiry, if the judgment is correct, each contract share can be redeemed for up to $1 USDT; if incorrect, the share becomes worthless. Example: A user purchases 1 Up contract for 0.01 USDT. At settlement, if the Up direction is confirmed, the contract is worth 1 USDT. If the down direction is confirmed, the contract is worth 0 USDT. Core Features Clear profit and loss.Published on 8 Apr 2026Updated on 16 Apr 2026Product documentationARK Core (ARK) Mainnet Upgrade: Depositing and Withdrawal Suspension
