MicroStrategy Bitcoin Risk: What MSTR and STRC Tell Us

Strategy now holds more Bitcoin than BlackRock. It has raised $25 billion in a single year. And it has built a capital structure unlike anything else in corporate finance. Here is what that actually means for anyone paying attention in 2026.

Key Points

• Strategy, formerly MicroStrategy, holds 818,334 BTC as of April 27, 2026, acquired for approximately $61.81 billion at an average cost of $75,537 per coin. That represents approximately 3.9% of all Bitcoin that will ever exist and makes Strategy the largest corporate Bitcoin holder in the world, overtaking BlackRock’s IBIT in April 2026.
• The company funds its Bitcoin purchases through a combination of $8.2 billion in convertible debt, over $28.7 billion in common stock sales, and a suite of five perpetual preferred stock instruments, including STRC, its flagship variable-rate product. Total preferred dividend obligations are projected to reach $904 million in 2026, creating a fixed cost layer that must be serviced regardless of Bitcoin’s price.
• STRC, launched in July 2025 at a 9% dividend yield, is Strategy’s most recent and most actively used capital-raising instrument. It currently pays 11.5% annually in monthly cash dividends on a $100 par value and has scaled to a $6.4 billion market cap. It is the primary engine of Strategy’s recent Bitcoin accumulation and is designed to generate non-dilutive capital for common shareholders.

Strategy is one of the most debated names in finance right now. Depending on who you ask, it is either the most visionary corporate treasury experiment in Bitcoin’s history or a leveraged bet of historic proportions that could end badly if Bitcoin’s price does not cooperate. The reality, as usual, sits somewhere in the middle, and understanding the specifics matters a great deal more than picking a side.

How Strategy Became the World’s Largest Corporate Bitcoin Holder

The story starts in August 2020, when then-CEO Michael Saylor converted MicroStrategy’s cash reserves into Bitcoin rather than leaving them in dollars. At the time, the company held about $250 million in treasury. The reasoning was straightforward: fiat currency was being debased by stimulus spending and Bitcoin, as a fixed-supply asset, offered a superior store of value over the long term.

What began as a treasury allocation became something far more ambitious. In October 2024, Strategy announced the 21/21 capital plan to buy Bitcoin with $42 billion raised by selling $21 billion of MSTR equity and $21 billion of fixed income securities by 2027. That plan was subsequently upsized into the 42/42 plan targeting $84 billion in total capital raises through 2027 after the equity component was fulfilled ahead of schedule.

Strategy now holds 815,061 BTC, surpassing BlackRock IBIT’s 802,824 BTC, marking its first lead since Q2 2024. As of April 27, 2026, that figure has grown further to 818,334 BTC, acquired for approximately $61.81 billion at an average cost of $75,537 per coin. MicroStrategy controls 65.6% of all Bitcoin held by publicly traded companies, highlighting its unmatched position as the largest corporate BTC holder.

The company achieved 22.8% Bitcoin Yield in 2025, meaning each MSTR share represented 22.8% more Bitcoin at year end than it did at the start. Year-to-date 2026, Bitcoin Yield stands at 9.6%.

The Capital Structure: How Strategy Pays For All of This

Understanding Strategy’s risk profile requires understanding exactly how the company raises the capital to buy Bitcoin. It is not simply borrowing money and buying coins. The architecture is considerably more layered than that.

Strategy used four primary instruments: convertible notes at approximately $8.2 billion at a 0.42% average coupon, at-the-money stock offerings totalling over $28.7 billion, perpetual preferred stock across five series, and operating cash flow from its software business generating approximately $477 million in annual revenue.

The convertible notes are the most structurally significant risk. These are bonds with maturities extending into the 2028 to 2030 window. If Bitcoin’s price is significantly lower when these notes mature, Strategy may face pressure to refinance at less favourable terms or liquidate holdings to meet obligations.

The company has never sold Bitcoin in meaningful quantities, having made only one small sale of 704 BTC in 2022, but the debt maturities create a future inflection point that cannot be ignored.

Total debt is projected to reach $13 billion by the end of 2025 and $19 billion by the end of 2026. Annual interest payments are forecast to rise from $48 million in 2025 to $87 million in 2026. Meanwhile, preferred stock dividend payments are expected to rise from $217 million in 2025 to $904 million in 2026.

That $904 million in preferred dividend obligations for 2026 is the number that deserves the most attention. Unlike interest on debt, preferred dividends are not technically mandatory in a legal sense, but missing them triggers compounding penalty rates and reputational damage that would impair Strategy’s ability to raise further capital. In practice, they function as near-fixed obligations.

What is STRC and why does it matter?

STRC, officially the Variable Rate Series A Perpetual Stretch Preferred Stock, is Strategy’s most recently launched and most actively used capital-raising instrument. STRC launched in July 2025 via a $2.5 billion IPO at a 9% initial dividend yield, paying monthly cash dividends at a variable rate on a $100 stated amount per share.

The mechanics are distinctive. Strategy adjusts the monthly dividend rate to steer the share price toward $100 par. When the stock drifts below par, Strategy raises the yield to attract buyers; when it holds near par, the rate can stay flat or eventually be cut. After seven consecutive monthly raises totalling 250 basis points, the rate held steady at 11.5% in April 2026, the first month without an increase since launch.

As of mid-April 2026, STRC had scaled to a $6.4 billion market cap, with approximately $339 million of 30-day average daily trading volume and 1.7% 30-day historical volatility.

What makes STRC structurally important to understand is how it relates to MSTR common shareholders. Unlike common stock ATM offerings, which dilute existing shareholders by increasing the share count, STRC issuance is the non-dilutive engine. Strategy raises capital without issuing common stock, buys Bitcoin, and increases BTC per MSTR share. This is why Strategy has increasingly shifted toward STRC as its primary funding vehicle: it allows Bitcoin accumulation to continue while protecting common shareholders from the dilution that defined earlier capital raises.

Strategy describes STRC as its flagship Digital Credit instrument. As STRC continues to trade around par despite a decline in Bitcoin’s price from its all-time high, Strategy now has a non-cyclical tool for raising funds to acquire more Bitcoin.

For investors in STRC itself, the instrument functions as a high-yield income product with Bitcoin as the underlying collateral. Bitcoin only needs to grow at 2% annually for STRC dividends to be sustainably covered, against Bitcoin’s 15-year compound annual growth rate of approximately 80%. That framing makes STRC attractive to income investors who are structurally bullish on Bitcoin but want monthly cash flow rather than pure price exposure.

The Full Preferred Stock Family: STRK, STRF, STRD, STRC, and STRE

STRC is the most recent and most discussed of Strategy’s preferred instruments, but understanding the full capital stack requires knowing where each series sits.

STRK carries an 8% perpetual dividend and is convertible to MSTR common stock at roughly $1,000 per share, trading near $72 against $100 par and yielding an effective 10.6%. STRF carries a 10% fixed cumulative dividend and is non-convertible, making it the most conservative option. STRD carries a 10% non-cumulative dividend with the highest risk-reward profile among the fixed-rate series. STRE, launched in November 2025, is a euro-denominated instrument targeting European institutional investors.

Each series represents a different risk-return position in the capital stack. STRC sits in the middle: more yield than STRF, variable rather than fixed, cumulative if dividends are missed, and without the equity conversion upside of STRK. STRC is variable-rate and cumulative, with its rates designed to keep it near par. STRD is non-convertible with a 10% non-cumulative dividend and the highest risk-reward profile.

The combined ATM capacity across all preferred instruments, alongside the remaining common stock program, gives Strategy over $30 billion in potential future capital raises available at any time.

What Are the Real Risks of the MicroStrategy Bitcoin Strategy?

The bull case for Strategy is straightforward: Bitcoin continues its long-term appreciation, BTC Yield compounds, preferred dividend obligations are comfortably covered, and MSTR shareholders see their per-share Bitcoin exposure grow year after year.

The bear case is equally clear, and investors deserve a direct account of it.

The company’s Bitcoin holdings are directly tied to price volatility, with its average acquisition cost currently close to or above spot market price, leading to unrealized losses during Bitcoin downturns. The substantial debt burden of over $8.2 billion requires constant access to capital markets, mainly via stock sales, which can dilute existing shareholders and raise costs.

MSTR amplifies Bitcoin’s moves in both directions. When BTC rises, MSTR typically outperforms it. When BTC falls, MSTR falls harder. Bitcoin’s price action is the only thing that fundamentally matters. MSTR fell approximately 77% from its all-time high of $543 in November 2024 to approximately $121 as of early 2026, even as Strategy continued accumulating Bitcoin throughout the decline.

The capital needed to generate one basis point of Bitcoin Yield has risen from approximately $126,000 in August 2021 to approximately $5.5 million by May 2025. This reflects a fundamental mathematical reality: as the Bitcoin base of Strategy grows, each new BTC contributes less marginal yield, and the capital required increases exponentially, creating a declining ceiling on sustainable yield.

The dual-class share structure gives Saylor effective voting control regardless of economic dilution, meaning common shareholders have limited ability to influence the strategy even if they disagree with it. The software business that originally gave Strategy its operating identity now contributes approximately $477 million in annual revenue, a relatively small figure against the scale of the Bitcoin treasury operation it supports.

Strategy makes use of a procyclical leverage flywheel which has allowed it to acquire an increasing number of Bitcoin. Market participants have feared that Strategy could come under financial pressure in case of Bitcoin price drawdowns. Although MSTR continues to hold low amounts of liquidity, insolvency and bankruptcy risks remain low and Bitcoin supply liquidations are not imminent.

The honest assessment is that Strategy is not on the verge of collapse. But it is a company whose financial health is entirely dependent on one asset’s price performance, servicing growing fixed obligations from an accumulation model that becomes mathematically less efficient at scale. Whether that trade-off is worth it depends entirely on your conviction about where Bitcoin’s price goes from here.

What Does This Mean for STRC Investors Specifically?

For investors evaluating STRC as an income instrument rather than an MSTR equity play, the risk calculus is different from that of common shareholders.

STRC sits higher in the capital stack than common equity, meaning preferred dividends must be addressed before any value is returned to common shareholders. The cumulative nature of STRC means that if Strategy misses a dividend payment, it accumulates at the prevailing rate and must be made whole before any common distributions are possible.

The instrument is designed to be near-par and low-volatility relative to MSTR common stock. Its 1.7% 30-day historical volatility as of April 2026 compares to MSTR’s dramatically higher price swings, which reflects the instrument functioning as intended for income-focused investors.

The key risk for STRC holders is not immediate insolvency but rather the long-term sustainability of Strategy’s ability to issue new preferred capital to fund Bitcoin purchases that generate the yield supporting the dividend. If Bitcoin enters a prolonged bear market that impairs Strategy’s credit and reduces demand for new STRC issuance, the company’s ability to maintain the Bitcoin Yield metric that justifies the dividend framework comes under pressure.
