MicroStrategy’s 538,000 BTC treasury after $2.1 billion note raise

Capital accumulation through debt

MicroStrategy’s September 2026 raise of $2.1 billion in convertible notes fuels its ongoing Bitcoin accumulation. This latest move expands a treasury that holds 538,000 BTC according to the latest company strategy. The company seeks to increase its Bitcoin per share, a metric management calls "Bitcoin yield," to maximize value for common shareholders. While the core software business generates revenue, most investors treat the stock as a leveraged Bitcoin proxy. If you already know the software business acts as a side show, you know the real story lies in the Bitcoin treasury. The disconnect strikes me. The strategy began in August 2020 when the company used $250 million of its balance sheet to buy 21,454 BTC. Since then, the company shifted from a software firm to a levered Bitcoin financial vehicle. By 2026, Strategy held over 800,000 BTC, accounting for approximately 4% of the total Bitcoin supply.

The $2.1 billion note carries specific terms that define the capital structure. These 0% interest notes provide bondholders the option to convert into Class A common stock if the price reaches a specific threshold. This mechanism allows the company to access cheap capital to purchase more Bitcoin.

The 0% interest structure allows the company to access cheap capital to purchase more Bitcoin. If Bitcoin prices rise significantly, bondholders convert their debt into equity, which prevents immediate cash outflows but dilutes existing shareholders. This mechanism helps the company avoid large cash repayments during bull markets. However, if Bitcoin prices drop, the company faces a massive liquidity requirement.

The mechanics of the premium

The market frequently prices MicroStrategy at a premium to its net asset value. This premium stems from the company’s ability to use financial leverage in ways most investors cannot. For example, management uses the volatility of its Bitcoin holdings to fund further purchases. This creates a recursive loop where rising Bitcoin prices drive higher stock prices, enabling more debt issuance.

Regulatory constraints also drive much of the demand for the equity. Many investors cannot purchase Bitcoin directly because of investment mandates or lack of secure custody solutions. This renders the stock an attractive proxy for those excluded from the asset class. The company’s ability to use Bitcoin as collateral also provides advantages for institutional holders.

Liquidity risks and debt obligations

The company faces $689 million in annual dividend and interest obligations. The company faces a severe liquidity risk if Bitcoin prices remain depressed for several years. In December 2025, management established a $2.19 billion cash reserve to cover these payments for approximately 21 months. The company faces $689 million in annual dividend and interest obligations, which requires careful management of the $2.19 billion cash reserve established in December 2025 to cover all of these specific payments for approximately 21 months.

In June 2026, the company sold 32 BTC to meet preferred-stock distribution obligations. This sale contradicted the usual "HODL" stance of the company. The company relies on its cash reserves and new debt to service existing obligations. The company’s STRD preferred stock shows just 3.1x Bitcoin coverage, which remains significantly lower than the 173.5x coverage seen in the 2028 convertible tranche. The company’s 2030 convertible bond matures on March 1, 2030, but bondholders can request their cash back a year early in March 2028 if the stock remains below the conversion price. If Bitcoin prices fall below the average buy price, the pressure on the treasury intensifies. Does the company have enough liquidity to survive a multi-year Bitcoin bear market?
