How markets resolve

How XO Oracle settles a market, and what a void actually means.

XO Oracle determines the final outcome using the rules published with the market. A trustworthy resolution starts before trading opens: the market has to define its decision window, primary source, any allowed secondary source, the outcome conditions, and the circumstances that make it void.

The stages

Stage	What happens
Rules published	The market exposes its question, outcome conditions, evidence sources, timing and void fallback.
Trading ends or market pauses	New order entry stops according to lifecycle state. Paused markets retain resting orders; terminal states cancel them.
Evidence reviewed	The resolver evaluates the designated source, using a secondary source only under the published conditions.
Outcome recorded	The market becomes Resolved with a winner, Voided under its defined invalid case, or Closed without resolution under engine rules.
Portfolio updates	Winning or void-refund positions appear as claimable after settlement and indexing.
You claim	Your smart wallet redeems through the appropriate contract path.

Voids

A void is not a loss and not a win. It means the market could not be settled under its own rules — typically because the event was cancelled, the evidence source became unavailable, or the question turned out to be ambiguous in a way the rules did not anticipate.

Eligible positions in a voided market follow the refund path defined in that market’s published rules. Read the void clause on the market page before trading; it varies by market, and it is the clause people skip.

Closed without resolution

A market can also reach Closed — terminal, with no outcome recorded, under engine rules. Like Resolved and Voided, this cancels resting orders.
