Every prediction market contract eventually resolves. Understanding the resolution process, including how outcomes are determined, when payouts happen, and what can go wrong, prevents surprises when your positions reach their conclusion.

What resolution means

Resolution is the moment a prediction market contract settles to its final value. If the event happened, Yes contracts pay $1 and No contracts pay $0. If the event didn't happen, the reverse. Once a market resolves, all open positions close automatically and payouts are distributed to the winning side.

The resolution process depends on the type of event and the platform hosting the market. Some events resolve instantly and cleanly. Others require interpretation, verification, or a waiting period before the final result is confirmed.

How outcomes are determined

Different types of events use different resolution mechanisms. Sporting events typically resolve based on official league results published immediately after the game. These are among the cleanest resolutions because the outcome is unambiguous and available within minutes.

Political events like elections resolve based on official certified results, which can take days or even weeks after the initial vote. Markets may show an apparent winner on election night, but formal resolution waits for the official call from the relevant authority.

Economic data releases, like inflation or jobs numbers, resolve based on the official figures published by the reporting agency. These are typically clear-cut, though revisions to economic data can occasionally create confusion about which number counts.

More subjective events, like "Will Company X launch Product Y by Q3?" require clear definitions upfront about what counts as a launch and what the deadline means. Well-designed markets specify these parameters in the contract terms before trading opens.

The role of oracles and verification

On blockchain-based prediction platforms, resolution often involves an oracle, which is a system that brings real-world information on-chain to settle contracts. Oracles can be automated data feeds, human organization committees, or hybrid systems that combine both.

The reliability of the oracle matters. If the oracle reports the wrong outcome, contracts settle incorrectly. Most platforms address this through dispute mechanisms that allow participants to challenge a resolution before it becomes final. Understanding how a platform's oracle and dispute system works helps you assess the risk of a resolution error on any contract you trade.

What happens to your position at resolution

When a market resolves in your favor, the payout credits to your account automatically. You don't need to take any action. Your Yes contracts convert to $1 each (or your No contracts, depending on which side you held), and the proceeds become available for trading or withdrawal.

If the market resolves against you, your contracts go to $0 and the capital you allocated to that position is lost. This is the binary nature of prediction markets: there is no partial payout on a standard Yes/No contract.

Edge cases and disputes

Not every event resolves cleanly. An event might be canceled, postponed indefinitely, or produce an outcome that doesn't clearly match any of the contract's defined terms. Platforms handle these situations differently. Some void the market and return all funds to participants. Others follow specific rules laid out in the contract terms.

Before trading any market, read the resolution criteria in the contract details. Knowing exactly what conditions trigger a Yes, No, or void resolution protects you from situations where you were right about the outcome but wrong about how the contract defines it.
