Quick Answer

Each Opinion market states its own resolution method and sources. Most markets currently use Opinion AI as the primary oracle. When a proposed outcome is published, a dispute window opens before payout is finalized. The current dispute system allows the first eligible user to challenge that resolution as either a wrong result or too early by staking the required amount of OPN and optionally submitting evidence. The dispute can be accepted, rejected or time out, with different consequences for the proposed result and the stake.

​
Key Takeaways

  • The individual market page controls the resolution method and evidence sources.
  • Most markets currently use Opinion AI as the primary oracle, but users should not assume every market does.
  • A proposed resolution normally enters a dispute window before finalization.
  • The current Docs say the window is typically two hours, except for some asset-price markets; the live market timer controls.
  • Only one dispute can be filed for a proposed resolution, and the first filing takes the slot.
  • Filing and claiming require on-chain transactions and user-paid gas.

​
Resolution and Dispute Are Two Different Stages

Resolution determines the proposed outcome under the market’s written rules and sources. Dispute is the challenge period after that proposal and before final payout. The lifecycle is:
  1. The market reaches the point defined in its rules.
  2. A result is proposed using the stated resolution method.
  3. A dispute window opens and payout is not yet final.
  4. If no dispute is filed, the proposal finalizes after the window.
  5. If a dispute is filed, it enters review.
  6. The result is accepted, rejected or timed out under the documented process.

​
Who Resolves an Opinion Market?

The official resolution page says most markets currently use Opinion AI as the primary oracle. The specific market page remains the controlling source for:
  • the question and possible outcomes;
  • the resolution time or condition;
  • the named source or sources;
  • exceptions such as postponement, cancellation or an event that has not happened;
  • the resolution method used for that market.

​
Who Can File a Dispute?

The current Docs say any user can file during an active dispute window by connecting a wallet, choosing a reason and staking the required OPN amount. The two documented reasons are:
  • Wrong Result: the proposed outcome is incorrect.
  • Too Early: the event or required condition has not happened yet.
The user may include a written explanation and supporting URLs. Evidence should address the market’s actual rules, not merely the user’s preferred interpretation.

​
How Much Must Be Staked?

The documented requirement is:
The OPN amount is determined using the Binance OPN/USDT exchange rate when the first resolution is proposed. Opinion states that it may adjust the stake percentage by market category. The exact amount displayed on the market’s dispute page is the number to verify before committing.

​
Possible Dispute Outcomes

An accepted or timed-out dispute therefore returns 2× the original staked amount in total: the stake plus an equal reward. The user pays gas to file and, when applicable, claim.

​
Important Conditions and Exceptions

  • The dispute window duration is market-specific even though two hours is described as typical.
  • Some asset-price markets may use a different window.
  • Only the first dispute is accepted for a proposed resolution.
  • A timeout does not necessarily end the market lifecycle; the market can be re-resolved.
  • The live market page is the source for the timer, stake and current status.
  • Product rules can change, so older screenshots should not be used as the final reference.

​
How to Evaluate a Proposed Resolution

  1. Read the exact question and outcome definition.
  2. Check the designated source and time boundary.
  3. Determine whether the event occurred and whether it is final under the rule.
  4. Use evidence that directly supports “Wrong Result” or “Too Early.”
  5. Review the required stake, gas and remaining time before filing.

FAQ

The current Docs describe it as typically two hours, except for some asset-price markets. Each market displays its own timer, which should be treated as authoritative.
The current dispute guide says any user can file during the active window by staking the required OPN and confirming the on-chain transaction.
No. The current process permits one dispute per proposed resolution, and the first submitted dispute takes the slot.
If accepted, the original resolution is overturned and the disputor can claim the original stake plus an equal OPN reward.
The dispute succeeds automatically, the stake and equal reward can be claimed, and the market may be re-resolved later.
The official Docs say most currently do. The resolution method specified on the individual market page takes precedence.Educational information only. Resolution and dispute rules can change; verify the live market and current Docs.
