MicroStrategy’s Bitcoin Holdings Crossed 400,000 BTC

MicroStrategy disclosed on December 2, 2024 that it had acquired approximately 15,400 bitcoin for approximately $1.5 billion, pushing the company’s holdings above 400,000 BTC. The purchases occurred from November 25 through December 1 at an average price of approximately $95,976 per bitcoin, including fees and expenses.

The filing mattered because it showed, in unusually direct form, how a publicly traded company was turning access to U.S. equity markets into large-scale bitcoin demand. MicroStrategy did not describe the purchase as an allocation from ordinary cash reserves. It said the bitcoin was bought with proceeds from selling its own Class A shares under an at-the-market program.

The equity-to-bitcoin transaction

During the same November 25–December 1 window, MicroStrategy sold 3,728,507 shares and received approximately $1.48 billion in net proceeds after sales commissions. Its October 30 sales agreement authorized up to $21 billion of Class A share issuance through a group of sales agents. Approximately $11.3 billion of that capacity remained on December 1.

The company and its subsidiaries then held approximately 402,100 BTC. MicroStrategy reported an aggregate purchase cost of approximately $23.4 billion and an average cost of approximately $58,263 per bitcoin, both including fees and expenses. Those were company-reported holdings and cost figures in an SEC filing; the filing did not identify wallets, counterparties, individual execution times or custody arrangements that would permit transaction-by-transaction independent verification.

Crossing 400,000 BTC was institutionally significant even without assigning a market value to the position. It demonstrated that MicroStrategy’s bitcoin strategy was no longer simply a corporate-treasury decision funded by retained cash. By December 2, it operated as a capital-markets mechanism: issue equity, use the proceeds to acquire bitcoin, and measure the result partly by bitcoin held per assumed diluted share.

What “BTC Yield” did—and did not—measure

MicroStrategy reported “BTC Yield” of 38.7% for October 1 through December 1 and 63.3% for January 1 through December 1. The label could be mistaken for investment income, but the company expressly defined it otherwise. The KPI measured the percentage change in the ratio of bitcoin holdings to “Assumed Diluted Shares Outstanding,” a denominator that included actual shares plus shares assumed from convertible notes, options and equity awards.

The company said it used the metric to assess whether bitcoin acquisitions were accretive to shareholders as they related to bitcoin holdings. It also listed important limitations. BTC Yield was not operating performance, liquidity, a return on the bitcoin, a return earned by shareholders or a predictor of MSTR’s share price. The calculation did not account for debt and other claims senior to common equity, and it could overstate or understate the effect of capital raising.

That distinction is central to interpreting the December 2 announcement. The disclosed share sale increased the number of actual shares while the bitcoin purchase increased the numerator. A positive company-defined KPI did not eliminate dilution, financing risk, bitcoin-price risk or the possibility that MSTR shares could trade at a premium or discount to the value of the company’s bitcoin.

What the disclosure established

The verifiable event-day conclusion was narrow but consequential. MicroStrategy announced a completed, approximately $1.5 billion bitcoin purchase; said the acquisition was funded with equity-sale proceeds; and reported that its holdings had reached approximately 402,100 BTC as of December 1. Contemporaneous CoinDesk and The Block reports independently described the same filing and financing chain.

The disclosure did not establish that the purchase caused a particular bitcoin-price move. It also did not prove future purchases, future access to favorable financing or future shareholder returns. The remaining $11.3 billion of authorized issuance represented capacity, not cash already raised or bitcoin already committed. On December 2, the importance of the filing was the scale and repeatability of the model it documented—not a guaranteed outcome for either bitcoin or MicroStrategy investors.
