Polymarket Faces A Strategy Bitcoin Market Lawsuit

Two Polymarket traders have sued the prediction-market platform over a disputed Strategy Bitcoin contract, turning a market-resolution fight into a court test for event-contract payout rules.

The complaint names traders William Wood and Thomas Bush as plaintiffs and names Polymarket CEO Shayne Coplan and chief marketing officer Matthew Modabber as defendants.

The lawsuit was filed in the New York Supreme Court on July 3.

Their filing brings contract and good-faith claims, along with unjust-enrichment, deceptive-practice and false-advertising allegations.

Their requested relief includes the $1-per-share value they say their “Yes” positions should have received, along with damages and legal fees.

Wood wrote on July 6 that his own claimed loss was $500K and that 1,868 traders together lost $6.5M.

That statement is part of the public dispute around the case; the court still has to decide whether the plaintiffs can prove those claims.

Strategy Filing Sat Behind The Disputed Market Deadline

The complaint says the market question turned on whether Strategy sold Bitcoin on or before May 31.

Strategy's later SEC filing, dated June 1, listed a 32 BTC sale between May 26 and 31.

The timing created the central dispute: the sale period fell before the market deadline, but the public confirmation arrived one day later.

Polymarket's note said late confirmation would not qualify under the market's timeframe, and the contract resolved “No” after UMA token holders voted through the platform's dispute-settlement oracle.

The plaintiffs argue that Strategy's filing was unambiguous proof under the market's own rules because those rules designated the company's disclosures as the primary source.

The complaint says Polymarket damaged its promise of objective outcomes by adding a confirmation deadline after the fact.

It alleges that refusing to honour a documented event lets the platform control payout rather than resolve truth.

Polymarket has not publicly responded to the complaint.

Bloomberg And The Wall Street Journal Cited Disputed-Market Pressure

The lawsuit lands as prediction-market operators face closer scrutiny over how outcomes are settled.

Decrypt reported that Polymarket's dispute count topped more than 1,150 markets in 2026, above last year's total.

Bloomberg and the Wall Street Journal investigations found concentration among large wallets and said many UMA voters also had stakes in markets they helped judge.

Burwick Law brought the Strategy case and said it is weighing similar claims from other traders.

Decrypt described the Strategy fight as Polymarket's largest dispute since last year's $237 million market over whether Ukraine's president wore a suit.

Decrypt also reported that Polymarket's U.S. arm has CFTC-registered exchange status, that NYSE parent ICE has put close to $2 billion into the platform, and that the company's last valuation was $9 billion.

It also said Polymarket was reportedly seeking $400 million in April at a $15 billion valuation.

Polymarket Has Not Publicly Answered The Complaint

The court case does not decide whether prediction markets are useful or legal as a category.

It focuses on whether one Strategy contract followed the settlement rules traders believed governed the market.

For payment and event-contract platforms, the case puts settlement governance ahead of product growth.

The complaint challenges whether a platform can add a timing condition after a real-world event is documented by the stated primary source.

The lawsuit also raises a conflict question around oracle voters who may hold positions in the markets they help settle.

Polymarket has not publicly responded to the complaint, and the available record does not include a court ruling, a settlement timetable, UMA voter identities, or a final damages amount beyond the plaintiffs' request for the $1-per-share value of their “Yes” shares plus damages and legal fees.
