Polymarket Bettors Split on Strategy Bitcoin Sale Date in $79M Dispute

A $79 million dispute has erupted on Polymarket over the exact timing of a bitcoin sale by Strategy (MSTR), splitting bettors on whether a trade counts when it is executed or when it is confirmed.

The Polymarket contract asked a simple question: did Strategy sell any bitcoin by May 31? The company's filing says it sold 32 BTC between May 26 and 31. The filing came out June 1. That gap has split bettors into a $79 million fight over whether a sale counts when it happens, or when it's confirmed. The dispute turns on a single ambiguity: the rules ask whether Strategy sold bitcoin "by 11:59 PM ET" on May 31, but they don't say whether that means the sale must have occurred by then or been confirmed by then. Strategy executed the trades between May 26 and 31 and dated the activity "as of May 31, 2026, 4:00 p.m. Eastern Time" — inside the window. But the 8-K disclosing them wasn't filed until June 1.

For cryptocurrency traders, this dispute highlights the importance of precise contract language in decentralized prediction markets. Polymarket's resolution mechanism relies on community consensus and oracles, which can be tested when edge cases arise. The outcome could set a precedent for how similar time-bound events are adjudicated. Traders should monitor how the market resolves this ambiguity, as it may influence future contract design and settlement practices.

Looking ahead, the resolution of this contract will depend on Polymarket's community vote or designated oracle. The case underscores the growing complexity of prediction markets as they intersect with corporate disclosure schedules. Traders should watch for any updates from Polymarket's team on how they plan to handle the ambiguity, as well as any potential impact on MSTR's stock price or bitcoin market sentiment.
