Polymarket Sued Over Bitcoin Sale Resolution After Shifting Market Rules

Published by James Harris on July 7, 2026July 7, 2026

Two traders filed suit against Polymarket in the Supreme Court of the State of New York on July 3, alleging the platform refused to pay out on a market that asked whether Strategy would sell any Bitcoin by May 31, 2026. Strategy did sell. On June 1, the company filed a Form 8-K disclosing that it sold 32 BTC between May 26 and May 31, its first disposal since December 2022, at an average net price of $77,135 for roughly $2.5 million total. Plaintiffs William Wood and Thomas Bush say that filing, which the market named as its primary resolution source, answered the binary question with a clear yes.

Polymarket disagreed. The platform posted clarification language that shifted the resolution frame from whether Strategy sold Bitcoin by the deadline to whether that sale had been publicly confirmed within the market’s timeframe. When the 8-K was filed, yes odds jumped from around 10% to 80%, and at least one trader reportedly bought approximately 700,000 yes shares near 76 cents each, treating the position as near-certain arbitrage. After Polymarket’s team posted that confirmation outside the market’s timeframe did not qualify, yes shares fell below a cent. After two disputes and a 48-hour final review, the contract resolved no for the third time, settling near 99.7 cents on the no side, according to Galaxy Research.

When Resolution Criteria Become the Product

The original contract text, per Galaxy Research’s analysis, was event-based: Strategy selling “any of its Bitcoin” by the deadline, with no requirement that the sale be announced within that window. The clarification Polymarket issued reframed an event-based market as a disclosure-based one, retroactively. That distinction is the entire lawsuit.

This is not the first time a prediction market’s resolution stack has ended up in a New York courtroom over exactly this kind of definitional edge. In March, Kalshi faced a lawsuit over its “Ali Khamenei out as Supreme Leader?” market, where a plaintiff alleged the platform used a “death carveout” to avoid paying out. The pattern is consistent: a platform writes contract language loosely enough to capture user interest, an edge case materializes, and the platform applies a narrowing interpretation that happens to reduce its liability. Galaxy Research called the Strategy episode the highest-stakes test of Polymarket’s resolution infrastructure since last year’s $237 million Zelenskyy suit market.

The suit alleges breach of contract, violation of the implied covenant of good faith, unjust enrichment, and deceptive business practices under New York General Business Law. The plaintiffs also target Polymarket’s marketing, which positions the platform as a place where markets “seek truth,” arguing those claims become fraudulent if resolution standards can shift after an outcome is known. On the mechanics: while settlement runs through the UMA Optimistic Oracle, the complaint argues Polymarket retained control over drafting rules and issuing the clarifications that determined the outcome.

The Regulatory Overhang Makes This Harder to Dismiss

Polymarket is already reportedly under CFTC examination across several parts of its business, including separate allegations that the company paid content creators to post videos showing simulated trades and fabricated winnings, which Polymarket has not publicly addressed. A lawsuit that directly challenges the integrity of the resolution process lands differently when a federal regulator is already looking at the platform’s conduct.

The $301 million in volume this single market generated illustrates what is actually at stake in these resolution disputes. Public companies holding Bitcoin as a treasury asset, a category that now extends well beyond Strategy to include firms like Strive, which ranks seventh among public Bitcoin holders with nearly 20,000 BTC, create a recurring class of binary events that prediction markets will keep listing. Each one carries the same structural tension: event-based contract language, a disclosure cycle that does not align neatly with market deadlines, and platforms that retain discretion over how those gaps get resolved.

The market priced in doubt about the mechanism itself long before the lawsuit was filed. Yes shares going from 80% to sub-1% on a clarification post is the signal. The litigation is just the documentation.
