Strategy (formerly MicroStrategy) is the largest Bitcoin treasury in the world, with more than 800,000 BTC on its balance sheet. But reducing its story to "they bought a lot of Bitcoin" misses the point. What Michael Saylor built from August 2020 is a financial-engineering machine that converts access to capital markets into Bitcoin per share. This is the case study every company considering the treasury model should understand.
The starting point: August 2020
MicroStrategy was a business-intelligence software firm with substantial cash being eroded by inflation. In August 2020 it converted $250 million of that cash into Bitcoin, the largest corporate purchase of its kind at the time. Three months later it surpassed $450 million. So far, this is a treasury decision. What came next created the category.
The engine: raising capital to buy more Bitcoin
Instead of limiting itself to its cash, Strategy began raising capital in public markets to buy more Bitcoin. It used three main tools, worth understanding:
Convertible debt. Bonds that pay low interest and that the investor can convert into shares if the stock rises. Strategy issued billions at very low rates — in some tranches, at 0% — because the investor paid for that discount in exchange for the conversion option.
ATM (at-the-market) equity offerings. Issuing new shares directly into the market, at the current price, continuously.
Perpetual preferred shares. Since 2025, Strategy issues preferreds — STRK at 8%, STRF at 10%, STRC at 11.5% monthly, STRD — that raise capital from institutional fixed-income investors in exchange for a fixed dividend, without directly diluting the common stock.
Every dollar raised through these channels was deployed into Bitcoin.
The key: issuing at a premium to NAV
Here is the genius and the point to grasp. Strategy's stock usually trades at a premium to the value of its Bitcoin on the balance sheet: that is mNAV, the multiple of market cap over the net value of the BTC. When mNAV is above 1, issuing new shares at that price lets the company buy more Bitcoin than the dilution costs existing shareholders. The result is that Bitcoin per share grows — the metric Strategy calls BTC Yield — without the shareholder putting in another cent. The market pays a premium for that value-creation machine, and that premium feeds the machine.
Why it works… and where the limit is
The engine is reflexive: high premium → ability to issue cheap capital → more Bitcoin per share → more confidence → high premium. But it works both ways. When mNAV compresses toward 1 (or below), issuing shares stops creating value and can destroy it, the cost of capital rises, and the ability to keep accumulating slows. That is why following mNAV is following the health of the model. Strategy traded at premiums above 3x in moments of euphoria; understanding that the premium is neither free nor permanent is understanding the model's risk. Our stress test shows the BTC price at which the structure runs out of margin.
What a company can learn
The replicable lesson is not "issue convertible debt." It is deeper: a treasury's value lies not only in how much Bitcoin it holds, but in its ability to grow Bitcoin per share over time using capital-market tools with discipline. Not every company has access to those markets or the scale to do it efficiently, and that is where most would be better off getting exposure through a vehicle that already masters this engineering — such as Standard 21, of whose ecosystem SatsIntel is the data arm — rather than trying to replicate it from scratch.
Summary
MicroStrategy/Strategy's balance-sheet strategy is the founding manual of corporate Bitcoin: raise capital at a premium, convert it into Bitcoin, grow BTC per share, repeat. It is brilliant while there is a premium and access to capital, and fragile when both disappear. You can follow its mNAV, BTC Yield and holdings live on its SatsIntel profile.
