MicroStrategy (MSTR) has expanded its Bitcoin holdings by $255 million in a single week, according to a disclosure on April 27, 2026. The company acquired 3,273 Bitcoin during the week ending April 26, 2026, bringing its total holdings to 818,334 BTC.

At current market prices, the company’s Bitcoin reserves are valued at approximately $63.7 billion. The purchase was executed at an average price of $77,906 per Bitcoin, funded through the sale of 1.45 million shares of Class A common stock via its at-the-market (ATM) equity program.

MicroStrategy also reported that its proprietary Bitcoin Yield metric reached 9.6% year-to-date 2026, up from 9.5% in the prior week. This metric measures the percentage change in the ratio between Bitcoin holdings and assumed diluted shares outstanding, offering insight into the company’s efficiency in acquiring Bitcoin relative to shareholder dilution.

The company’s cumulative Bitcoin position carries an average acquisition cost of $75,537 per coin, representing a total investment of $61.81 billion.

MicroStrategy Now Controls Nearly 4% of Total Bitcoin Supply

With 818,334 Bitcoin in its treasury, MicroStrategy now owns approximately 3.9% of the cryptocurrency’s fixed 21 million supply cap. The latest acquisition extends the company’s position beyond the holdings of BlackRock’s iShares Bitcoin Trust (IBIT), which holds approximately 802,823 BTC.

MicroStrategy’s Bitcoin reserves account for over 60% of all Bitcoin held by publicly traded companies worldwide, solidifying its dominance as the largest corporate holder of the digital asset.

Executive Chairman Michael Saylor’s Bitcoin Accumulation Goal

The latest purchase aligns with MicroStrategy’s ongoing Bitcoin treasury strategy under executive chairman Michael Saylor. Saylor has previously stated a goal of accumulating between 5% and 7% of the total Bitcoin supply.

Funding Through Common Stock ATM Program

The $255 million purchase was financed through MicroStrategy’s $21 billion Class A common stock ATM program. No preferred stock was issued during the April 20-26, 2026 period.

In March 2026, the company filed to establish dual $21 billion ATM programs for both MSTR common stock and STRC preferred stock, along with an additional $2.1 billion program for STRK preferred shares. This provides the firm with a total capital-raising capacity of $42 billion.

The common stock ATM program allows MicroStrategy to sell shares gradually into the market without traditional equity offerings, offering flexible funding for ongoing Bitcoin acquisitions.
