A $79 million Polymarket contract on whether MicroStrategy sold bitcoin by May 31 faces resolution deadlock over a fundamental question: does the market resolve based on when the sale occurred or when it was publicly disclosed?
MicroStrategy executed a 32 BTC sale between May 26 and May 31, 2026, according to the company’s filing dated May 31 at 4:00 p.m. ET. The company did not disclose the transaction publicly until June 1 via an 8-K filing. The Polymarket contract asked whether Strategy sold any bitcoin “by 11:59 PM ET” on May 31 but did not explicitly specify whether the sale itself or its confirmation had to occur by that deadline.
The dispute has fractured the market into competing camps. The “Yes” camp argues the contract is event-based and should resolve affirmatively because Strategy’s own filing confirms the sale happened within the deadline. The “No” camp contends the market is announcement-based and must resolve negatively because no public confirmation existed before the market closed. A third faction argues the contract language was too vague to resolve at all, citing wording that required a sale “on the date specified” rather than “by” it.
Polymarket has publicly endorsed the “No” interpretation, stating that “confirmation achieved outside of the market’s time frame does not qualify.” However, UMA token holders hold final authority over resolution through their voting system. The distinction matters structurally: MicroStrategy reports weekly, typically on Mondays, making month-end sale confirmation before month-end deadline inherently difficult.
The $2.5 million in proceeds from the bitcoin sale is immaterial to the market’s size. What is material is the precedent. The “Yes” contract price reached 81% before collapsing to under 1% as the dispute crystallized, indicating a dramatic repricing of the outcome probability as traders absorbed the timing ambiguity.
This is not the first time Polymarket and UMA have disagreed on resolution. In 2024, the two parties split over a Barron Trump memecoin contract, with Polymarket ultimately overruling UMA and refunding “Yes” holders. That precedent suggests the final outcome here remains uncertain despite Polymarket’s current position.
UMA token holders are expected to cast the decisive vote, though the timing and outcome of that vote have not been disclosed.
