MicroStrategy’s entire public story is wrapped around Bitcoin, so a market asking whether the company sells even a single coin is not just trivia. In the past day, two notable accounts landed on opposite sides of a fresh Polymarket question with a May 31, 2026 deadline — and once you look past the dollar size, the more interesting bet is by far the smaller one.
The bet
The market is simple: it resolves “Yes” if MSTR sells any of its Bitcoin by 11:59 p.m. ET on May 31, 2026. If not, it resolves “No.” The rules say the main sources will be MSTR’s own disclosures and on-chain data, with credible reporting available as backup.
Right now, the line is leaning hard toward “nothing happens by May.” The Yes side sits around 10.5¢, meaning the market is giving a sale by that deadline roughly a one-in-ten chance. The No side is around 89.5¢, and Yes is down about 4.5¢ on the day.
That is where the first account came in. At 09:28 UTC on May 6, wallet 0x69aa bought about $20k of No at 89¢. In plain English: it was betting that MicroStrategy does not sell any Bitcoin before the end of May 2026.
A few hours later, another account took the other side. Wallet 0x71ed bought about $3.7k of Yes at 10.7¢, taking the long-shot view that a sale does happen before that deadline.
The wallet
The Yes buyer is small in dollar terms here, but hard to dismiss. Its profile shows 318 closed positions, 265 wins, and 53 losses — an 83% hit rate — with about $430k in lifetime profit on roughly $10.3M invested. That is not a casual tourist account throwing a dart at a meme market.
It also has a funny bit of history with this exact theme. One of its biggest loss events is labeled “nothing-ever-happens-microstrategy,” a market where it dropped about $9k. That does not prove anything about today’s bet, but it makes the new Yes buy more interesting: this is an account with both a strong overall record and prior scar tissue around MicroStrategy-style questions.
The No buyer is notable for a less flattering reason. Its profile shows 953 closed positions, 713 wins, and 240 losses across more than $40M invested — a 75% win rate paired with a lifetime profit line down about $108k. Huge volume, frequent wins, slightly negative bottom line: that combination reads a lot more like a high-turnover account recycling spreads than a directional sharp expressing a view. It is the kind of wallet that drives a lot of price action without telling you very much about who is right.
What the market thinks
The May market is new and already active. It opened on May 5 and has done about $202k in 24-hour volume, with roughly $76k in resting liquidity. Over the last 24 hours, the Yes price started around 15¢, traded as low as 8.5¢, reached as high as 17.5¢, and ended near 10.5¢.
The really striking part is the calendar. The May 31 market says a sale is unlikely. The June 30, 2026 sibling market is much higher, with the last trade around 24.8¢. The December 31, 2026 version is around 53¢ — basically a coin flip.
So traders are not saying “MicroStrategy will never sell.” They are drawing a line between “before the end of May” and “later in 2026,” which is a narrower and more testable argument than the simple Yes/No would suggest.
What to watch
The order flow to watch is not just whether Yes moves up. It is whether buyers keep paying above the low teens, where the market has recently faded, or whether No keeps absorbing every attempt at a rebound. At the current 10¢–11¢ area, a few cents is a big change in implied probability.
The market also has a clean outside catalyst: any company disclosure, on-chain movement, or credible report pointing to a sale would matter immediately. Until then, the story is the gap between a high-volume No buyer who looks more like a market maker than a believer, and a proven, profitable account willing to put real money on the long shot.
