MicroStrategy disclosed on April 29, 2024, that it held 214,400 bitcoin as of April 26, extending the public company's unusually concentrated bet on the asset after another $1.65 billion buying campaign. The figure turned a quarterly software-company earnings release into a balance-sheet event for the Bitcoin market: one listed operating company had continued using cash, equity and debt to build a treasury position whose economic weight dwarfed its cash balance.
The stack grew by 25,250 bitcoin
The April 29 Form 8-K and attached earnings release said MicroStrategy acquired 25,250 bitcoin from December 31, 2023, through April 26, 2024, for $1.65 billion, an average of $65,232 per bitcoin. Its resulting 214,400-bitcoin position had an aggregate purchase cost of $7.54 billion and an average cost of $35,180 per bitcoin.
The company's event-day presentation provides the tighter chronology. Holdings rose from 189,150 bitcoin on December 31, 2023, to 214,278 on March 31, 2024, an increase of 25,128 during the quarter. MicroStrategy then bought approximately 122 more bitcoin between April 1 and April 26 for $7.8 million. Those figures reconcile to the announced 214,400 total, subject to the company's use of rounded acquisition counts and dollar amounts.
The scale was striking, but the filing did not make MicroStrategy a bitcoin fund. The company explicitly said it was an operating company, not an exchange-traded product or ETF, and that its shares were not designed to track the value of its bitcoin before expenses and liabilities. Unlike spot bitcoin products, it could actively issue securities, carry corporate debt, operate a software business and change its capital structure.
Debt and equity powered the strategy
The accumulation was inseparable from MicroStrategy's financing model. During March 2024, it issued $800 million of 0.625% convertible senior notes due 2030 and $603.75 million of 0.875% convertible senior notes due 2031. Its presentation showed $3.604 billion of principal debt outstanding across secured and convertible instruments, with a 1.27% weighted-average fixed annual interest rate and about $45.8 million of annualized fixed interest expense.
That leverage distinguished the company from a passive spot product. It could amplify gains when bitcoin appreciated, but debt service, refinancing, dilution and operating-company risks remained. The presentation's comparisons with spot products were management's positioning, not an assurance that MicroStrategy shares would deliver bitcoin's return.
Accounting obscured the economic exposure
MicroStrategy reported a $191.6 million digital-asset impairment charge for the quarter ended March 31, 2024. At that date, its 214,278 bitcoin had a $5.074 billion carrying value after $2.461 billion of cumulative impairment losses, against an original cost basis of $7.535 billion.
The company also estimated that position's March 31 market value at $15.220 billion, using a bitcoin price of $71,028.14 at 4 p.m. Eastern. Its April 26 presentation estimate was lower, about $13.7 billion, for 214,400 bitcoin. These are company-reported point-in-time valuations, not intraday ranges or independent composite prices; they should not be read as realized proceeds. The gap between carrying value and estimated market value showed how the then-applied impairment model could make the financial statements look very different from the treasury's market exposure.
Why April 29 mattered
The disclosure demonstrated that the launch of U.S. spot bitcoin products in January 2024 had not displaced MicroStrategy's leveraged corporate route to bitcoin exposure. Management instead presented the company as a “Bitcoin development company” able to combine software cash flow with capital-market fundraising.
For the market, the verified fact was the accumulated position and its financing. Claims that this structure would create shareholder value were management's view and remained contingent on bitcoin prices, financing conditions, software performance and the terms of outstanding securities.
Later filing context
A Form 10-Q filed on May 1, 2024, confirmed the 122-bitcoin April purchase and warned that the concentration limited diversification and enhanced the risks of the acquisition strategy. That filing postdated the April 29 announcement and is included only as confirmation, not as information available earlier in the event day.
