Strategy Inc—the company formerly called MicroStrategy—sold 32 bitcoin between May 26 and May 31, its first such sale since December 2022. The transaction, disclosed in a June 1 Form 8-K, was tiny relative to the firm's 843,706 BTC treasury: roughly $2.5 million at about $77,135 per coin, or 0.0038% of the total stash. But for a company whose chairman Michael Saylor has built a personal brand around never selling, the move broke an iron narrative.
First bitcoin sale in three years
The last time MicroStrategy reported a bitcoin sale was December 2022, when it unloaded about 704 BTC at a loss for tax reasons. This time the amount was trivial by comparison, but the optics matter. Strategy has accumulated more than 843,000 bitcoin through debt and equity raises; a sale of any size invites questions about whether the strategy is shifting. The 8-K didn't spell out a reason, and the company has not commented beyond the filing.
Polymarket's $85 million bet
The timing of the sale kicked off a messy fight on Polymarket. The prediction market had run a contract: “MicroStrategy sells any Bitcoin by May 31, 2026?” The market was dominated by “No” shares trading at 99.8 cents. Total volume across the question hit $85 million, with $53.86 million in open positions on the May 31 slice alone. When the public 8-K landed on June 1, Polymarket's oracle ruled that the confirmation came after the resolution window—locking the “No” outcome at full value.
Dispute over disclosure timing
That call didn't sit with everyone. More than $20 million in positions hinge on whether the event date (the sale between May 26-31) or the disclosure date (June 1) controls the outcome. Polymarket uses UMA's oracle infrastructure, and the dispute has already been escalated to UMA's Data Verification Mechanism (DVM), where token holders will vote over 48-96 hours. One displeased user posted: “This is why I'm losing faith in Polymarket. The sale was confirmed within the timeframe.” The platform hasn't responded publicly.
What happens next
UMA token holders now have the final say. If they side with the event-date interpretation, the “No” shares could be voided and the $53.86 million pool redistributed to “Yes” holders. A DVM vote typically resolves within two to four days. Until then, Strategy's 32-coin sale—barely a rounding error in its treasury—has turned into a million-dollar arbitration over a single tweet's worth of timing.
