What happened
Strategy disclosed the purchase of 1,036 BTC for $81. 9 million last week at a volume-weighted average price of $79,012, according to Bitcoin Magazine's report Sunday citing the company's filing. The buy lifts the firm's total holdings to 850,364 BTC, cementing its position as the largest corporate bitcoin holder by a wide margin.
It is a smaller tranche than the multi-thousand BTC prints Strategy was clipping at the cycle highs, and it lands in a week where spot traded in a tight range either side of the company's own blended cost. Saylor has not yet posted his customary Sunday chart, but the filing itself is the primary source. The company funds these purchases through a mix of at-the-market equity issuance, convertible notes, and preferred stock, and the cadence of buys has tracked the window in which its MSTR equity trades at a premium to the net asset value of the underlying bitcoin.
Why it matters
The headline isn't the size of the buy. It's that Strategy's aggregate cost basis is now above spot. For the first time since the 2024 drawdown, the single largest corporate bitcoin position on the planet is under water on paper.
That shifts the reflexive loop Saylor has engineered over the past three years. When MSTR trades at a premium to the per-share bitcoin it holds, the company can issue stock, buy more BTC, and grow BTC-per-share without diluting holders in economic terms. When the premium compresses, that machine slows.
A treasury sitting on an unrealized loss, combined with a stock that has given back a chunk of its 2026 gains, is the exact setup that historically narrows the mNAV multiple. The buy tells you Saylor is still buying through it. The size tells you the funding window is tighter than it was in Q2.
