MicroStrategy Closes $500 Million Bitcoin Bond and Opens $1 Billion Stock Facility

MicroStrategy closed a $500 million private sale of 6.125% senior secured notes on June 14, 2021, putting approximately $487.7 million of net proceeds behind its stated plan to acquire more bitcoin. In a separate filing on the same date, the enterprise-software company also established an at-the-market program that allowed it to sell as much as $1 billion of Class A common stock through Jefferies.

The paired transactions mattered because they widened the financing channels available for a public company’s bitcoin strategy. One was completed, interest-bearing debt whose proceeds were specifically earmarked for bitcoin. The other was only authorization to sell stock over time, with bitcoin listed among possible uses. Treating both as cash already raised would overstate the June 14 record.

What the debt closing established

The Form 8-K says the notes were sold for $500 million in aggregate principal, mature on June 15, 2028, and pay interest semiannually beginning December 15, 2021. They were offered to qualified institutional buyers under Rule 144A and to non-U.S. persons under Regulation S, rather than through a registered public offering.

A straightforward calculation—$500 million multiplied by the 6.125% annual coupon—produces $30.625 million of annual cash interest while the full principal remains outstanding. That calculation excludes any early redemption, repurchase, springing maturity, tax effect or other term that could change realized financing costs.

The security package was consequential. The filing described liens on substantially all assets of MicroStrategy and guarantor subsidiaries, including bitcoin or other digital assets acquired on or after June 14, 2021. It excluded the company’s existing bitcoin and certain assets derived from those holdings. In other words, the transaction did not simply express a bullish treasury view; it attached a fixed corporate obligation and collateral claims to the next phase of that strategy.

A second financing channel, not a second closing

MicroStrategy’s June 14 registration statement created an at-the-market facility for up to $1 billion of Class A shares, with Jefferies acting as sales agent. The prospectus said proceeds, if any, were intended for general corporate purposes, including bitcoin acquisitions, but management retained broad discretion. It imposed no minimum amount that had to be sold, and Jefferies was not required to sell a specific quantity.

That distinction sets the scale correctly. Adding the $500 million note principal to the $1 billion equity ceiling yields $1.5 billion of announced financing capacity, but only the note sale had closed on June 14. The debt produced about $487.7 million net; the equity program’s eventual gross sales, commissions, timing and bitcoin allocation were undetermined on the event date.

Why it mattered in June 2021

The equity prospectus reported that MicroStrategy held approximately 92,079 bitcoin as of June 4, acquired for about $2.251 billion at an average cost of approximately $24,450 per bitcoin, including fees and expenses. Against that already large position, the debt closing showed the company was prepared to incur secured, fixed-rate obligations to expand its exposure, while the equity facility gave management a route to raise capital without adding the same contractual interest burden.

For bitcoin markets, the immediate fact was potential corporate demand, not a verified June 14 coin purchase. For MicroStrategy shareholders and creditors, the more durable implication was balance-sheet transmission: bitcoin price volatility could increasingly affect asset values, collateral, financing choices and dilution. The filings made that coupling explicit while also preserving important uncertainty about when the equity facility would be used and how much of its proceeds would reach bitcoin.
