MicroStrategy, the leading corporate holder of Bitcoin, has made headlines once again with a massive acquisition of over 4,000 Bitcoin (BTC) in a single day, according to estimates from real-time trading data and community tracking dashboards.
The company, led by CEO Michael Saylor, appears to have funded this significant purchase through the issuance of its Variable Rate Series A Preferred Stock (STRC), a financial instrument that has become a key tool in MicroStrategy’s Bitcoin acquisition strategy. By the end of the trading day in New York, it is estimated that the firm had raised enough capital to acquire more than 4,000 BTC, marking the largest single-day Bitcoin purchase funded through STRC since its introduction.
This surge in activity follows a week of unusually strong trading. On March 10, STRC recorded a record $409 million in daily trading volume while maintaining a 30-day volatility of about 3% and a one-month volume-weighted average price near $99.78. The data suggests that the trading activity on that day alone funded the purchase of more than 2,000 BTC, which was already one of the largest one-day accumulations tied to the instrument.
Thursday’s pace easily surpassed that figure, nearly doubling the previous record. The company, which is already the largest public corporate holder of Bitcoin, has increasingly leaned on its preferred equity program to finance additional acquisitions. Earlier this year, MicroStrategy amended its at-the-market (ATM) program, allowing multiple agents to sell STRC shares simultaneously. This change has increased liquidity in the instrument and made it easier for the company to raise large amounts of capital quickly, with proceeds directed toward Bitcoin purchases.
Real-time dashboards tracking STRC trading attempt to estimate how many shares MicroStrategy itself is issuing versus secondary market trades. Because the company previously indicated it may sell shares when the price trades above its $100 stated amount, analysts can approximate the capital raised when trading occurs above that threshold. A recent SEC filing disclosed that the company purchased 17,994 BTC between March 2 and March 8 for approximately $1.28 billion. This acquisition lifted the firm’s total holdings to about 738,731 BTC, representing roughly 3.5% of Bitcoin’s circulating supply.
The filing showed that the purchase was funded through a combination of $377.1 million in STRC sales and $899.5 million raised through common stock issuance. Based on these figures, STRC accounted for about 29.5% of the funding for that five-day accumulation period, equivalent to roughly 5,300 BTC acquired through preferred share sales. If Thursday’s estimates prove accurate, the day’s purchases alone could exceed the average daily Bitcoin acquisition pace seen during that earlier buying window.
STRC acts as a bridge between traditional income investors and MicroStrategy’s Bitcoin-focused balance sheet. Income investors typically seek steady payouts, while MicroStrategy’s large Bitcoin holdings bring long-term upside along with short-term price swings. The preferred stock helps connect these two profiles by structuring the security to keep demand near its $100 par value while paying a monthly dividend that yields about 11.5% annually. This effectively converts the economics of a Bitcoin treasury into a format that appeals to fixed-income investors who prioritize regular income.
Strong liquidity and relatively low volatility suggest that the investor base is shifting toward income-focused capital, which can help stabilize trading activity compared with instruments driven mainly by speculation. These early results point to a product-market fit, suggesting that the structure meets a clear demand among investors seeking yield tied to Bitcoin exposure. For corporate leaders considering Bitcoin treasury strategies, STRC offers a way to integrate Bitcoin into broader capital structures, allowing companies to draw funding from multiple investor groups while building a shared strategic reserve around the asset.
At the time of writing, Bitcoin trades near $70,000, while shares of MicroStrategy (MSTR) are down about 0.75% on the day. The data remains unofficial, and MicroStrategy typically confirms purchases later through SEC filings or public disclosures. This latest move by MicroStrategy underscores the company’s continued commitment to Bitcoin as a strategic asset and highlights the growing acceptance of digital currencies in the corporate world.
