How market resolution works
Updated 5/1/2026
Every market on Granbay has an end date — a date after which the underlying question can be answered with a definitive YES or NO. Resolution is the process of recording that answer and paying out share holders accordingly.
Who resolves
During the closed beta a single Granbay admin resolves each market. Every resolution requires a written reason (≥30 chars) and an evidence URL pointing to a credible source — both are stored permanently on the market detail page so anyone can audit the call.
Before the public real-money launch (Gate 3), Granbay shifts to a multi-resolver model: at least two admins must agree on the outcome and a tiebreaker procedure handles disagreements. Until then, the closed-beta single-admin model carries the safeguards above + a dispute window for any user who believes a call was wrong.
When does it happen
Resolution can fire any time after the market's stated `closes_at` date, once the underlying question has a verifiable answer. Some markets resolve within minutes (e.g. a sports game's final score); others take days (e.g. a court ruling published the following week).
If you want to track which markets are pending resolution, the market detail page shows a 'Closed — pending resolution' state once `closes_at` has passed but the admin hasn't recorded an outcome yet.
What happens to your shares
On resolution, every YES share you hold pays out 100¢ if the resolved outcome was YES — and 0¢ if it was NO. NO shares mirror this: they pay 100¢ if the outcome was NO, 0¢ if it was YES. The payout fires in a single ledger transaction so your wallet balance updates atomically with the market's status flip.
If a market is voided (e.g. the question becomes un-answerable), every share is refunded at its purchase price. The 2% taker fee paid at trade time is not refunded — it covered the matching service rendered, regardless of the eventual outcome. See the Fees article for details.
Disputing a resolution
If you believe a resolution was wrong, file a dispute from the market detail page within 7 days of resolution. Provide a written reason (≥30 chars) and ideally an evidence URL pointing to a counter-source. Disputes are reviewed by a separate admin (not the resolver) and either upheld (resolution reversed, payouts re-run) or rejected with a written response.
While a dispute is under review the resolution stands — no payout claw-back. If the dispute is upheld, the reversal posts new ledger entries that net out the prior payout and apply the corrected outcome.
