Strategy, formerly known as MicroStrategy, has ignited a $15 million contention on the prediction market Polymarket following its first publicly disclosed bitcoin sale. This sale, while officially announced in a filing dated June 1, actually took place between May 26 and May 31, leading to a debate among bettors regarding the appropriate resolution date for the market contracts.
The relevant Polymarket contract, titled ‘MicroStrategy sells any Bitcoin by ___?’, is structured around specific timestamps. It will resolve to ‘Yes’ if any bitcoin was sold by 11:59 p.m. ET on the designated deadline. Currently, the contract is marked at 81% in favor of ‘Yes’ and is under review.
The complexity arises from the rules governing the resolution of these bets, which stipulate that outcomes depend on both the company’s filings and on-chain transaction data, supplemented by a consensus of credible reporting. Although the bitcoin sales occurred before the June 1 filing, the timing of the public disclosure is at the center of the dispute.
Supporters of the ‘Yes’ position argue that the sale was effectively completed before the May 31 deadline, as indicated in the 8-K filing. They contend that the contract should settle in their favor because the sale was presented as occurring before the deadline, specifically noted as of May 31, 2026, at 4:00 p.m. Eastern Time.
Conversely, those holding ‘No’ positions assert that no public information regarding the sale was available prior to the June 1 filing, which occurred after the May 31 deadline. This argument hinges on the interpretation that the sale’s public acknowledgment is critical for the resolution.
In addition to the May 31 contract, other contracts for June 30 and December 31 have been trading at 100% ‘Yes’, reflecting a strong belief in further bitcoin sales by Strategy. The volume across these three markets has reached approximately $24.7 million, with the May 31 market alone accounting for about $14.65 million.
The resolution of this dispute will ultimately be determined by UMA’s optimistic oracle, the system employed by Polymarket to adjudicate ambiguous markets. Typically, such disputes undergo a review process lasting two days.
Prior to the filing, Polymarket had indicated an 84% probability of any bitcoin sale by Strategy occurring before the end of the year, a significant increase from 10% earlier in the spring. This shift followed comments from CEO Phong Le during the first-quarter earnings call, where he referred to the ‘disciplined sale of bitcoin’ as a strategy for capital management.
The ongoing debate now centers not on the occurrence of the sale itself, but rather on the timing of the transaction and its implications for bettors seeking substantial payouts.
The recent bitcoin sale by Strategy has led to a significant dispute on Polymarket, with bettors divided over the timing of the sale's public disclosure. The outcome hinges on the interpretation of the company's filing date versus the actual transaction dates, impacting millions in bets.
