Strategy bought 535 BTC for roughly $43 million last week at an average price of $80,340, founder Michael Saylor said, lifting the company's total holdings to 818,869 BTC worth about $66.55 billion at current prices. The average cost basis across the full treasury now sits at $75,540, putting the position $4.7 billion in unrealized profit (+7.59%).
Why it matters
Strategy has been the dominant single corporate bid in the BTC market for nearly five years, and the pattern matters more than any single week's print: the company is still accumulating through a mature bull cycle rather than trimming into strength. The $80,340 buy price sits modestly above the corporate average, meaning this tranche itself is marginally underwater on paper — and Saylor funded it anyway.
Market impact
The 535 BTC figure is small relative to Strategy's overall stack and barely registers against daily spot volume, so the price-action signal is limited. The structural read is louder: a corporate balance sheet with 818,869 BTC continues to absorb spot supply at a steady cadence, reinforcing the case that institutional treasuries have become a persistent — not opportunistic — source of demand across cycles.
