When a prediction market settles, the platform determines the event's outcome and converts each contract to its final value—usually $1 if the outcome happened, $0 if it did not. Settlement can be automatic or use a reported source (an oracle); funds are credited to user accounts after verification and any applicable fees or disputes are resolved.

What happens when a prediction market settles?

When a settlement occurs, the market stops being a live prediction and becomes a final payout event. For binary Yes/No contracts that conversion is normally $1 for a correct outcome and $0 for an incorrect one. Settlement is the moment contracts are fixed into a cash value on the platform.

That conversion follows the market’s rules about the official resolution source, timing, and any dispute process. In other words, prices before settlement are market valuations; settlement is what fixes the actual dollar outcome for each contract.

How is the official outcome decided and when does settlement occur?

The market creator specifies a resolution source at creation. That might be an official public record, a predefined website, or a delegated oracle (an automated reporter). The platform uses that source to decide the outcome according to the written resolution clause.

When the underlying event concludes, the platform typically waits for the resolution window defined in the market rules. That window gives time for official results to be published or for disputes to appear. At the end of that window the platform or oracle declares the outcome — for binary markets that declaration is “Yes” or “No,” and for scalar markets a numeric value is posted.

How is my payout calculated when a market settles?

Contracts convert to their final value at settlement. For a binary Yes contract that resolves to Yes, each contract becomes worth $1; if it resolves to No, each becomes $0. The platform then credits or debits user accounts according to how many contracts each user held.

Example: if a Yes contract costs 62¢ and pays $1 if the event happens, buying one contract costs $0.62. If the event happens, the contract pays $1, so the gain before fees is $0.38. If the event does not happen, the contract expires at $0, so the loss is $0.62. Those are the simple cash flows that settlement produces, before any trading or withdrawal fees the platform charges.

What happens if the outcome is disputed, ambiguous, or the event is cancelled?

Not every event resolves cleanly. If the resolution source is unclear, results are overturned, or the event is postponed, many platforms pause settlement and open a dispute process or manual review. That process is designed to follow the market’s stated rules and can delay final payouts until the disagreement is resolved.

Some markets may be cancelled and refunded if they cannot be resolved according to their rules. In other cases a community or delegated oracle vote will determine the final outcome. Because dispute processes differ between platforms, always check the market’s resolution clause to understand how ambiguities will be handled.

When can I use or withdraw funds after settlement?

After conversion, platforms usually credit settled amounts to your platform balance. That does not always mean you can withdraw funds instantly. Withdrawals can be delayed by withdrawal processing times, fiat on-ramps, platform limits, or required waiting periods and fee schedules.

Some platforms pay out immediately and others take time depending on settlement workflow and payment rails. If you rely on access to funds quickly, review the platform’s withdrawal rules and any fees that apply; settlement determines the cash value, and platform policies determine when that cash becomes available to you.

Frequently asked questions

How long after an event does settlement usually take?

Timing varies by platform and market. Some markets settle automatically within minutes of an official result; others wait a specified resolution window or require manual review, which can take hours or days.

What happens if the event outcome is disputed?

Many platforms offer a dispute or appeal process. Settlement can be paused while evidence is reviewed, and the platform or a governance process will make the final call according to the market’s resolution rules.

Will I automatically get money in my bank after settlement?

Settled funds are typically credited to your platform account immediately or after a short processing step, but withdrawals to a bank or external wallet depend on the platform’s withdrawal procedures and timing.

Are prediction markets legal?

Rules vary by location and platform. See our dedicated guide on whether prediction markets are legal in the US.

What if a market is cancelled or declared invalid?

If a market is cancelled according to its rules, platforms usually refund the cost of contracts to users’ accounts. The exact process and timing depend on the platform’s policies and the reason for cancellation.
