MicroStrategy disclosed a $94.2 million bitcoin purchase funded by share sales

MicroStrategy disclosed on December 30, 2021 that it had purchased approximately 1,914 bitcoin for approximately $94.2 million in cash between December 9 and December 29. The company reported an average acquisition price of approximately $49,229 per bitcoin, including fees and expenses.

The same Securities and Exchange Commission filing showed how the acquisition was financed. Over the identical December 9–29 window, MicroStrategy issued and sold 167,759 Class A common shares through Jefferies at an average gross price of approximately $565.78 per share. The sales produced approximately $94.2 million in net proceeds after commissions and expenses.

That correspondence made the development more than another corporate cryptocurrency purchase. A Nasdaq-listed operating company had converted demand for its shares into additional bitcoin exposure, tying its treasury strategy directly to conditions in the public equity market.

The purchases covered three weeks

December 30 was the disclosure date, not the date of a single $94.2 million bitcoin order. The filing supplied only an aggregate covering December 9 through December 29. It did not identify execution venues, counterparties, timestamps, wallets, custodians or individual transaction prices.

A preceding December 9 filing reported that MicroStrategy bought approximately 1,434 BTC between November 29 and December 8 for approximately $82.4 million, at an average price of approximately $57,477 including expenses. The newly reported $49,229 average was $8,248 lower, or approximately 14.3%, by Coinburn’s calculation.

That comparison describes MicroStrategy’s reported acquisition averages across two different purchasing windows. It is not a universal bitcoin return: bitcoin traded continuously across fragmented venues, and neither filing provided a market index or time-weighted benchmark.

A $1 billion equity program reached its limit

MicroStrategy had established the at-the-market program with Jefferies on June 14, 2021. The prospectus authorized sales of as much as $1 billion of Class A common stock and said net proceeds could be used for general corporate purposes, including bitcoin acquisitions.

The December 30 filing said the cumulative aggregate offering price had reached approximately $1 billion as of the close of business on December 29, constituting the program’s maximum. The company therefore could not continue selling under that authorization without establishing another financing facility.

At-the-market issuance allowed shares to be sold over time at prevailing prices rather than through one fixed-price underwritten offering. It gave MicroStrategy access to equity capital, but it also increased the number of shares outstanding. Existing shareholders did not receive direct ownership of a specified portion of the purchased bitcoin, and the filing did not calculate a per-share benefit from the transaction.

The treasury position grew more concentrated

As of December 29, MicroStrategy reported holding approximately 124,391 BTC acquired for an aggregate purchase price of approximately $3.75 billion. Its reported average cost was approximately $30,159 per bitcoin, including fees and expenses.

Those figures were company disclosures, not an independently reconstructed on-chain balance. Because the amounts were labeled approximate, subtracting one reported balance from another can produce rounding differences and should not be treated as transaction-level verification.

The scale nevertheless mattered institutionally. MicroStrategy was demonstrating that a public company could repeatedly use securities markets—not only operating cash—to build a concentrated bitcoin treasury. Its shares consequently combined exposure to the enterprise-software business, bitcoin prices, financing decisions, dilution and corporate liabilities. They were not interchangeable with bitcoin itself.

What the December 30 record established

The defensible event-day conclusion was narrow but significant: MicroStrategy disclosed approximately 1,914 additional BTC and approximately $94.2 million of matching net share-sale proceeds, while announcing that its $1 billion equity program had reached its maximum.

The record did not establish that the purchases moved bitcoin’s price, that the executions were favorable, or that the strategy would benefit shareholders. It established the quantities, reporting window and financing mechanism—and showed public equity becoming an institutional channel for corporate bitcoin accumulation.
