Strategy just dropped another $2.01 billion on bitcoin. The company disclosed the purchase in an SEC Form 8-K filing dated May 18, 2026, revealing it acquired 24,869 BTC between May 11 and May 17 at an average price of $80,985 per coin.

The firm now holds 843,738 bitcoin, purchased for a combined $63.87 billion at an average cost of $75,700 per coin.

As Strategy posted on X, the company has “achieved BTC Yield of 12.6% YTD 2026.” That figure sits at the centre of this filing and is the one most coverage glosses over. BTC Yield is Strategy’s internal performance metric tracking how much bitcoin exposure per diluted share grows over time. At 12.6% year-to-date, that number shows the equity raises are not just moving BTC totals up — they are moving per-share bitcoin value up too.

The Machine Behind the Buy

The $2.01 billion did not come from the company’s software revenue. It came from its at-the-market offering program, specifically from STRC, the Variable Rate Series A Perpetual Stretch Preferred Stock. Between May 11 and May 17, Strategy sold 19,519,801 STRC shares with a notional value of $1.952 billion, netting $1.949 billion after commissions. The company also sold 430,344 MSTR Class A common shares, generating $83.7 million in additional proceeds.

Thomas C. Chow, Executive Vice President and General Counsel of Strategy Inc., signed off on the 8-K filing on behalf of the company on May 18, 2026.

The STRC preferred stock is becoming a more predictable buying trigger than most have tracked. Vetle Lunde, Head of Research at K33, outlined in a May 13 report how the stock’s ex-dividend date structure, set on the 15th of each month, drives investor accumulation in the days before cutoff. That demand pushes STRC back toward its $100 par value, giving Strategy the window to issue new shares and deploy proceeds into BTC. The week just disclosed fits that pattern precisely.

$17.5 Billion Left in the Tank

What has not been widely noted is how much runway the ATM program still has. As of May 17, $17.51 billion in STRC capacity remains available for issuance. MSTR common stock has $26.27 billion in capacity left, reflecting both the current offering and a $21.0 billion increase announced back in March 2026.

For a crypto investor watching Strategy’s moves as a proxy for institutional bitcoin demand, these figures carry real weight. The pace of these purchases, roughly $2 billion weekly, is not slowing.

As Strategy posted on X, the figures represent a continued pace that shows no structural deceleration in accumulation. The company has now added over 63,000 BTC in less than two months based on prior disclosures tracking holdings from 780,897 in mid-April.

The Counter Case

The strategy does carry a specific risk condition that the filing itself does not address directly. Strategy reported $14.5 billion in unrealized losses on digital assets during Q1 2026 after bitcoin dropped roughly 20% from highs earlier in the year. If BTC enters a sustained pullback from current levels, the preferred dividend commitments, STRC pays a variable rate currently set at 11.50% annually, could strain the company’s ability to continue issuing shares at par. A sustained drop below Strategy’s $75,700 average cost basis would also eliminate the mark-to-market gains underpinning market confidence in the MSTR equity.

The STRC structure itself has no collateral backing from bitcoin holdings. Strategy’s own SEC disclosures state the preferred securities carry only a residual claim on company assets and are not backed by any specific BTC position.

The company’s software business does not generate enough cash to independently cover preferred dividend obligations. The engine only keeps running as long as shares trade near par and BTC holds ground.
