William Wood and Thomas Bush filed a lawsuit in the Supreme Court of the State of New York against prediction market platform Polymarket, CEO Shayne Coplan, Chief Marketing Officer Matthew Modabber, and affiliated entities over a disputed market resolution. The plaintiffs allege breach of contract, deceptive business practices, unjust enrichment, and false advertising following Polymarket's resolution of a market asking whether Strategy would sell any Bitcoin before May 31, 2026. The dispute arose after Strategy disclosed in an SEC Form 8-K filed on June 1 that it had sold 32 BTC between May 26 and May 31, yet the market resolved 'No' following Polymarket's decentralized dispute process. The lawsuit escalates one of the crypto industry's most contentious prediction market disputes into a legal battle and highlights governance challenges facing platforms as they handle contracts involving delayed corporate disclosures.
Plaintiffs Allege Improper Market Resolution by Polymarket
According to court filings, the plaintiffs argue that the market should have resolved 'Yes' because Strategy's SEC filing, identified in the contract as the primary resolution source, confirmed that Bitcoin sales occurred before the May 31 deadline. The complaint states that Polymarket improperly introduced or relied upon a requirement that the sales also needed to be publicly confirmed before the deadline, even though the SEC filing documenting the transactions was released one day later, on June 1.
The lawsuit alleges that changing or clarifying the resolution criteria after trading had ended undermined the platform's promise that predetermined, objective rules govern markets. The complaint opens by stating: 'A prediction market has one purpose: to reward people for being right about the world.'
The plaintiffs are seeking damages, including the full redemption value of their 'Yes' positions, legal fees, and other relief to be determined by the court. The dispute is one of the biggest governance controversies in Polymarket's history, with prominent market participants publicly questioning whether the platform's resolution process is objective for high-value contracts.
Prediction Market Governance Faces Scrutiny After $45 Billion Trading Volume
Polymarket and Kalshi reported a combined $45 billion in trading volume in June, reflecting growing institutional and retail interest in event-based markets. The lawsuit highlights one of the biggest governance challenges facing such platforms: determining how contracts should resolve when new information becomes available after a specified deadline for an event tied to the contract.
Legal experts and market participants have increasingly debated whether decentralized oracle systems provide sufficient certainty for contracts involving delayed corporate disclosures or regulatory filings. At the time of publication, Polymarket, Shayne Coplan, and the other defendants had not publicly responded to the allegations contained in the lawsuit, and the court has not ruled yet.
