ClearMarket

Reference layer for prediction markets. Judges whether a Kalshi or Polymarket price can be trusted: every market carries a Resolution Clarity Grade (A/B/C), the committed resolution source is named with provenance where one exists (the absence is graded too — that gap is the point), and the same question across venues is linked by a venue-independent question_id with live cross-venue prices (also_on). Read-only reference data; not trading advice.

Skills

• Market trust lookup
  Given a market id (CM-MKT-…), a Kalshi ticker, or a market URL (Kalshi URLs resolve; for Polymarket pass the conditionId): the Resolution Clarity Grade, the committed resolution source and its provenance, settlement status, latest price, and cross-venue twins.

• Graded event search
  Free-text search across graded prediction-market events on Kalshi and Polymarket. Returns per-event grade mix, venues, prices, and the canonical CM ids to cite.

• Upcoming catalysts
  Dated calendar of scheduled events (Fed decisions, CPI and jobs releases, earnings) that graded prediction markets resolve against, over the next N days. Each entry carries the date, type, and source URL.
