In prediction markets, the resolver plays a central role in ensuring that events settle correctly. Depending on the platform, the resolver may be a smart contract, a decentralized oracle, a designated third party, or a community-driven arbitration system. Its job is to deliver a clear, verifiable outcome once the event concludes.
Platforms like Polymarket and Myriad often use oracle-based systems where trusted data feeds provide the result. Omen-style markets use Reality.eth, where community members submit answers and escalate disputes if needed. Regardless of the structure, the resolver must follow transparent rules so traders understand exactly how and when the market will settle.
A reliable resolver ensures fairness, reduces disputes, and improves confidence in forecasting. The resolver’s actions also become part of the prediction markets data, giving analysts insights into resolution timing, disputes, and overall system reliability.
Accurate resolution is essential to prediction markets. A trustworthy resolver protects traders, prevents manipulation, and ensures that prediction markets data reflects true, verified outcomes.
Prediction markets depend on resolvers because trades cannot be finalized until an accurate outcome is confirmed. Without a resolver, markets would remain in limbo, undermining trust and usability. Resolvers ensure that everyone is paid correctly and that the forecasting system remains fair. Their accuracy directly shapes prediction markets data quality and long-term platform credibility.
On Polymarket, outcomes are delivered through oracle systems that verify event results from trusted data sources.
On Omen-style markets, Reality.eth collects user-submitted answers and allows challenges; if disputes arise, results may be escalated to an arbitration layer.
On Myriad or Manifold, resolvers may be platform operators or automated rules tied to transparent data feeds.
In each case, the resolver follows structured logic to ensure accurate settlement and clean prediction markets data.
Analysts can study how quickly resolvers deliver outcomes, how often disputes occur, and whether resolution patterns differ across event categories. Slow or inconsistent resolution may signal oracle weaknesses or ambiguous market design. Reliable resolver performance enhances prediction markets data by ensuring outcomes are trustworthy and timely.
Polymarket uses an oracle-driven resolver to settle markets on financial indicators, policy decisions, and crypto milestones. For example, in a market predicting whether Bitcoin would surpass a specific price by month-end, the resolver pulled verified price data from a trusted external feed and settled the market automatically once the event concluded.
Resolvers generate essential outcome data that supports forecasting accuracy analysis. FinFeed's Prediction Markets API provides structured prediction markets data—including resolution timestamps and final outcomes that developers can use to evaluate resolver reliability, build monitoring tools, and improve market design.
