summary: Prediction-Market Clarification Impact Pricer
description: 'Prices a prediction-market rules clarification as a trade. Given an open Polymarket market (slug, URL or conditionId; Kalshi ticker supported), reads the posted clarification (Additional context) from the UMA adapter on Polygon, or takes your clarificationText to price a pending or hypothetical one. Finds the real-world outcomes whose resolution changed, quotes each changed clause verbatim, shifts fair probability by their ensemble-estimated mass with an adversarial check, walks the live order book at your size after fees and slippage, and returns verdict.action BUY_YES / BUY_NO / EXIT / HOLD / NO_MATERIAL_CHANGE with edge in bps, fractional-Kelly size, confidence and reason_code. Closed markets return HOLD without a model call; if the estimate stage fails you still get the verified scenarios as a partial result. Not financial advice.
