The score has two inputs

Resolution clarity · 45%

Looks for official or price-source language, measurable thresholds and resolution mechanics. It penalizes subjective judgment, rumors, unclear announcements and event definitions that may be contested.

Market realism · 55%

Applies market-specific heuristics to patterns such as exact sports scores, short-window crypto prices, official economic releases, weather measurements and political event definitions.

How labels are assigned

  • 90–100 · StrongUnusually clear and realistic relative to nearby markets.
  • 80–89 · GoodA better candidate, but rules still require review.
  • 60–79 · WatchClarity or realism has a material weakness.
  • 1–59 · RiskyWeak fit for this screening strategy.

What the score does not measure

Price, APR, volume and liquidity do not increase this score. Those fields remain separate comparison metrics in the feed. The score also does not use a complete historical results database, know private information, predict the winning outcome or guarantee fair resolution.

It is a deterministic text heuristic and can miss unusual rules, context or data-source details. Read the resolution guide and the original Polymarket rules before relying on any label.
