Strategy's Bitcoin buying machine just hit a wall
The financial mechanism that has allowed Strategy, the corporate Bitcoin treasury formerly known as MicroStrategy, to accumulate roughly eight hundred and forty-seven thousand Bitcoin and become the single largest publicly traded corporate holder of the asset is showing visible strain this month, after the company's STRC preferred stock fell below par for the first time and forced a pivot in how the company funds its ongoing purchases.
The shift is clear in the size of recent buys. After spending months acquiring Bitcoin in multi-billion-dollar weekly waves through preferred share issuance, Strategy has slowed to two consecutive weeks of roughly one hundred million dollars, with the latest fifteen hundred and eighty-seven coins purchased at an average price of sixty-three thousand dollars and funded entirely through common stock rather than preferred shares. The company also disclosed its first net Bitcoin sale in nearly four years in late May, selling thirty-two coins for two and a half million dollars to cover near-term dividend payments on its STRC perpetual preferred stock.
The mechanics matter because Strategy's accumulation depended on a specific kind of arbitrage. The company issued preferred shares at a premium to par value, used the proceeds to buy Bitcoin, and then paid the dividends from a combination of operating cash flow and occasional Bitcoin sales when funds ran low. The premium pricing was what made the arbitrage profitable, because every dollar raised bought more Bitcoin than the dollar of dividend obligation it created. Once the shares drop below par, the math reverses, and the company has to either fund through dilutive common stock, sell some of the Bitcoin it already owns, or pause entirely. All three are now visibly happening.
For Bitcoin holders the implication runs deeper than one company. Strategy alone holds roughly four percent of the entire circulating supply, and its accumulation has been one of the largest sources of structural demand outside the spot ETFs. The company is not stopping, but its weekly buy rate has dropped by more than ninety percent from the peak, and the math that funded the earlier pace is now visibly broken. The question is not whether Strategy survives, but whether anyone replaces the scale of demand it provided.
