Bitcoin: Strategy’s surprise sale sparks battle on Polymarket

Strategy sold bitcoin for the first time since 2022. The amount remains small, but the symbol is huge. The controversy launched by Polymarket transforms this operation into a test of confidence for the story carried by Michael Saylor.

Strategy breaks a taboo around bitcoin

Strategy sold 32 bitcoins between May 26 and 31, for approximately $2.5 million. This figure seems almost ridiculous in the face of its colossal reserves. However, it hits hard, because Strategy had recently displayed a massive ambition to accumulate bitcoin. The contrast is therefore brutal.

The company remains the largest listed holder of bitcoin. She still had over 843,000 BTC at the end of May. The sale therefore represents a drop in the bucket. But in the Saylor universe, a drop can make a noise. For years, the message seemed simple: buy, accumulate, never sell.

This time, Strategy sold. Not to flee bitcoin. Not to liquidate his position. But to finance distributions linked to its preferred shares. The gesture is accountable. The signal becomes political. It introduces a nuance that the market does not always like.

Polymarket turns the date into a battlefield

The controversy is not only about the sale. It's about when it should count. Strategy sold its BTC before May 31. But the information was made public on June 1. This discrepancy was enough to trigger an argument on Polymarket.

The prediction market linked to May has been resolved to “No”. The one related to June was resolved to “Yes”. In other words, the sale of bitcoin did take place at the end of May, but it counted for June, because its official disclosure arrived on June 1st. The nuance seems technical. However, it was costly for some participants.

The real discomfort comes from the vote of UMA, the system responsible for resolving the dispute. A few large bitcoin holders weighed heavily in the decision. This concentration of power fuels an old criticism of decentralized finance: it promises open governance, but the whales often end up holding the pen.

The “never sell” narrative loses its veneer

Michael Saylor has long embodied a hard line. Bitcoin had to be accumulated, preserved, almost protected. This posture has made Strategy a sort of safe listed on the stock exchange. Many investors weren't just buying a stock. They were buying conviction.

Selling 32 BTC does not destroy this strategy. It makes it more adult, therefore less mythological. Strategy shows that it can use a small part of its reserves as a financial tool. It's rational. But this breaks the purity of the story. And in the markets, stories are sometimes worth as much as balance sheets.

Precedent counts. Tomorrow, every tension on debt, dividends or preferred shares will raise the same question again. Will Strategy sell again? This is precisely what makes this sequence sensitive, as JPMorgan already linked an ambitious bitcoin target to Strategy's ability to hold on.

This case comes at a fragile moment for bitcoin. The market is already digesting ETF outflows, liquidations and macroeconomic tensions. In this setting, even a tiny sale can be magnified by fear. The problem is not volume. It's the symbol.

Strategy has not abandoned bitcoin. Far from it. Its reserves remain gigantic, and its exposure remains central. But the company points out something often forgotten: even the biggest believers sometimes have to manage their cash flow, their deadlines and their investors.

The market will therefore monitor future movements with more suspicion. If Strategy resumes its purchases, the incident will quickly be put away. If other sales follow, the controversy will take on another dimension. After the Mt. Gox shock, this case further shows that bitcoin remains extremely sensitive to sell signals, even when they are limited.
