Polymarket accused of changing market rules mid-trade in Strategy Bitcoin sale dispute
Polymarket is facing trader backlash after users said the platform altered how a live bet would be judged after millions of dollars had already been placed. The dispute centers on a market tied to a $3.8 million Strategy Bitcoin sale. Traders accused Polymarket of moving the goalposts, raising questions about the platform's market-resolution integrity.
Resolution integrity is the core trust mechanism for any prediction market. A mid-market rule change on a high-dollar contract could erode trader confidence and invite regulatory scrutiny of Polymarket's dispute processes.
Second Polymarket market-integrity crisis in eight days, after the UMA oracle upheld 'No' on the same Strategy Bitcoin sale contract, leaving the offshore platform exposed on resolution finality while Kalshi races to tighten trader surveillance on its CFTC-regulated rival venue.
