Strategy sold 32 BTC for $2.5 M between May 26‑31, sparking a Polymarket dispute and a New York lawsuit over market resolution rules.

Strategy sold 32 Bitcoin between May 26 and May 31 for roughly $2.5 million, prompting a Polymarket trader to challenge the market’s “Yes/No” resolution and leading to a lawsuit alleging rule changes after the fact. The dispute highlights how prediction markets handle events disclosed after a deadline, a question that could affect future contracts.

| At a glance | |
|---|---|
| Sale size | 32 BTC |
| Sale value | $2.5 M |
| Disclosure date | June 1 filing |
| Market outcome | Resolved “No” after UMA vote (98.6% support) |

## Sale details and market wording clash  
MicroStrategy, now renamed Strategy, disclosed in a June 1 filing that it sold 32 BTC between May 26 and May 31 at an average price of $77,135 per coin, generating about $2.5 M in proceeds [1]. The Polymarket contract asked whether Strategy would sell any Bitcoin by 11:59 p.m. ET on May 31, but the platform later resolved the market as “No,” interpreting the deadline as requiring disclosure by that date rather than the actual sale [2]. A trader identified as 0xDinosaur bought 49,695.76 “Yes” shares for roughly 35,000 USDC, arguing that the sale occurred before the deadline even though the filing was made after [1].

## Legal fallout and broader implications  
On July 3, traders William Wood and Thomas Bush filed a New York Supreme Court lawsuit accusing Polymarket of breaching contract terms by altering the resolution criteria post‑sale [2]. The plaintiffs seek damages of at least $797,198 for denied redemption value or $596,281 for acquisition‑cost restitution. Polymarket’s decision was ratified through a UMA vote, with 98.6% of voting power supporting the “No” outcome [2]. The case underscores tension between on‑chain data, official disclosures, and prediction‑market rules, raising questions about how future contracts will define “sale” versus “disclosure” deadlines.

## What to watch
- **Polymarket’s rule revisions** – monitor any updates to market wording or resolution protocols that could affect similar contracts.  
- **Future Strategy Bitcoin transactions** – watch for additional sales, such as the 3,588 BTC sold for $216 M between June 29 and July 5, which may trigger new prediction‑market activity [2].  
- **Legal outcomes** – the New York lawsuit’s resolution could set precedent for how prediction markets enforce pre‑defined terms.

The dispute puts a spotlight on the precision required in prediction‑market contracts and may force platforms to tighten language around filing dates versus transaction dates, influencing how crypto‑related events are bet on going forward.
