Traders sue Polymarket over disputed Bitcoin sale ruling

Two traders have filed a lawsuit against Polymarket, the operator of an online prediction market, challenging the platform's resolution of a contract titled ‘Strategy: Bitcoin Sale'. The plaintiffs say the market was settled incorrectly and ask a court to review the outcome and award relief for their alleged losses.

Polymarket offers tradable contracts that pay out based on real-world events. Contracts on the platform are resolved either by automated mechanisms or by human review under published rules, sometimes using external data. The traders' complaint argues the platform applied an incorrect method or interpretation when finalizing the Bitcoin market.

The filing names two individual traders as plaintiffs and the company that runs the prediction market as defendant. It frames the dispute as one of contract interpretation and settlement fairness and asks the court to set aside or revise the market's outcome and to award damages tied to the disputed settlement. The complaint does not specify the exact date of the contested resolution or the court where the lawsuit was filed.

The plaintiffs ask the court to determine whether Polymarket followed its stated rules in resolving the contract and to order corrective relief if it did not. The filing asserts the platform's resolution diverged from the market's terms and says internal dispute procedures were insufficient, prompting the traders to seek judicial review.

The complaint highlights how disagreements over resolution methods, documentation and transparency can affect participants in private prediction exchanges. The public filing details the relief the traders seek and the legal grounds for their claim; it does not include a response from Polymarket.
