S&P's First-Ever Rating for a Bitcoin Treasury Company
S&P Global Ratings has assigned a 'B-' issuer credit rating to Strategy (formerly MicroStrategy, ticker MSTR), with a stable outlook. This marks the first time a major credit rating agency has rated a Bitcoin Treasury Company. The rating reflects Strategy's 'high bitcoin concentration, narrow business focus, weak risk-adjusted capitalization, and low U.S. dollar liquidity,' according to S&P. The company reported $8.1 billion in pre-tax earnings in the first half of 2025, almost entirely from appreciation in the value of its bitcoin holdings. While the balance sheet is dominated by bitcoin, management has prudently staggered debt maturities and maintained flexibility by financing primarily with equity. The rating implies that Strategy can meet debt obligations for now but faces significant default risk if market conditions worsen.
Strategy raises capital through equity and debt issuances to purchase and hold bitcoin. Its securities provide investors with varying exposure to bitcoin across its capital structure. On the same day of the rating, founder and former CEO Michael Saylor announced the purchase of 390 BTC between October 20 and October 26, spending approximately $43.4 million at an average price of $111,053 per Bitcoin. The firm still operates a small AI-powered analytics business, though it remains roughly breakeven.
Key Risks and Rating Drivers
S&P stated that Strategy's risk-adjusted capital ratio was significantly negative as of June 30, 2025, because the agency deducts bitcoin assets from equity in its calculation. Operating cash flow during the period was negative $37 million despite the $8.1 billion pre-tax profit. The agency cited several key risks, including a currency mismatch between bitcoin-denominated assets and dollar-denominated obligations (interest, debt principal, and preferred dividends). Cybersecurity risks were also highlighted given the company's reliance on custodians to safeguard its bitcoin.
Strategy holds bitcoin valued at roughly $70 billion, against $8 billion in convertible debt, much of which matures beginning in 2028. Annual preferred dividends total about $640 million, which the company plans to fund through additional stock and preferred equity issuance. While access to capital markets remains a core strength, S&P warned that a sharp decline in bitcoin prices or loss of investor confidence could impede its ability to refinance debt or pay dividends, potentially leading to bitcoin sales 'at severely depressed prices.'
S&P said the rating could be downgraded if access to markets weakens or debt management risks rise. An upgrade is unlikely unless the company improves its U.S. dollar liquidity or reduces reliance on convertible debt.
Saylor's Trillion-Dollar Endgame
Earlier this year, Michael Saylor laid out an ambitious plan to reshape global finance through Bitcoin in an interview with Bitcoin Magazine. He described an 'endgame' in which Strategy accumulates a trillion-dollar bitcoin balance sheet, growing 20–30% annually, and uses it as the foundation for a new global credit system. The core is scale: with enough BTC on corporate balance sheets, Bitcoin's long-term appreciation—historically around 21% annually—would supercharge the capital base. On top of that, Saylor sees an opportunity to issue bitcoin-backed credit at yields two to four percentage points higher than traditional fiat-based debt. He argued that over-collateralization could make this system safer than even AAA-rated debt, while simultaneously fueling broader financial growth.
Saylor's vision extends beyond credit markets. As Bitcoin becomes embedded in corporations, banks, insurers, and sovereign wealth funds, public equity indexes could gradually become indirect bitcoin vehicles. This would benefit equity markets and corporate balance sheets while introducing higher yields and greater transparency into financial products. The implications are broad: savings accounts could yield 8–10% instead of near-zero, money market funds could be denominated in bitcoin, and insurance products could be reimagined around bitcoin collateral.
