MicroStrategy Inc. (Nasdaq: MSTR), the enterprise software firm formerly known as Strategy Inc., announced on Monday, June 15, 2026, that it has acquired an additional 1,587 Bitcoin (BTC) for approximately $100 million.
Led by Executive Chairman Michael Saylor, the company executed the purchases between June 8 and June 14, 2026, at an average price of $63,024 per token. The acquisition, detailed in a Form 8-K filing with the U.S. Securities and Exchange Commission (SEC), brings the firm’s total treasury to 846,842 BTC.
The purchase was funded through the sale of 1,732,553 Class A shares under the company’s ongoing at-the-market (ATM) offering program, which generated $209 million in net proceeds. In addition to the Bitcoin buy, MicroStrategy increased its USD reserve by $100 million to a total of $1.1 billion.
This cash buffer is earmarked for debt servicing and preferred dividends, providing a shield against the volatility that often impacts Bitcoin signals and market structure as institutional participation grows.
MicroStrategy now controls more than 4% of Bitcoin’s fixed 21 million supply. Following the announcement, the company’s stock jumped nearly 7% in premarket trading to $132.67 before closing the regular session up 3.18% at $123.97. Bitcoin itself traded around $66,000 to $66,230 on Monday, reflecting a gain of approximately 3% over the prior 24 hours.
Michael Saylor maintains aggressive Bitcoin accumulation strategy
The cumulative cost of MicroStrategy’s total holdings has now reached approximately $64.07 billion. Because the company has purchased assets during various market peaks, its average purchase price for all holdings stands at $75,656 per BTC. With current market prices trailing this average, the firm is carrying an unrealized loss of roughly $8.06 billion, representing a 12.59% decrease from its entry point.
Executive Chairman Michael Saylor remains undeterred by paper losses, signaling his intent on Sunday by posting “Still adding dots” on X. He followed up on Monday, stating, “Strategy has acquired 1,587 $BTC for $100 million to increase our $BTC Reserve to ₿846,842. We have also increased our USD Reserve by $100 million to $1.
1 billion.” This persistent buying comes even as Bitcoin supply on exchanges suggests other large players are also tightening the available liquidity.
Analyst Quinn Thompson noted the financial pressure of this model, pointing out that MSTR trades near 0.8 times the net value of its Bitcoin. This valuation can strain the company’s leverage-driven funding mechanism. However, the company still maintains a significant war chest for future moves, with approximately $25.75 billion in remaining capacity under its current ATM stock program as of mid-June.
Financial health and the billion dollar cash reserve
The decision to bolster the USD reserve to $1.1 billion is a strategic countermeasure to the company’s debt obligations. MicroStrategy carries preferred shares with survival coupons as high as 11.5%.
By holding over a billion dollars in cash, the company can meet interest payments and dividends without being forced to sell its Bitcoin during market downturns. This is a critical buffer given that Bitcoin targets higher support levels amid substantial ETF outflows and shifting macro conditions.
The company’s “BTC Yield”—a proprietary metric used by Saylor to measure Bitcoin per share—has been slightly diluted. It moved from 13% on June 1 to approximately 12.5% following this latest share issuance. Despite this, the company’s market capitalization remains robust at approximately $47 billion, though its Price-to-Sales (P/S) ratio of 84.73 is significantly higher than its historical average.
While the firm buys, internal sentiment among executives appears more cautious. Over the past three months, company insiders have sold $26.3 million worth of shares, and no insider buying has been reported during that timeframe. For now, MicroStrategy remains a unique corporate experiment in cryptocurrency treasury management, holding a position that will likely dictate the company’s narrative for the remainder of 2026.
