On Sunday, Michael Saylor posted a timeline of Strategy's historical BTC purchases on X, captioned "Think bigger." The market read this as a prelude to another accumulation. More notably, he dropped a number: 2.05%.
Saylor's Magic Number: 2.05%
Saylor argued that as long as Bitcoin's annualized return stays above 2.05% (his "BTC Breakeven ARR"), Strategy can pay preferred stock dividends indefinitely without diluting MSTR common shareholders. Given Bitcoin's historical annualized returns often exceeding 40%, this bar appears absurdly low.
Strategy currently offers three preferred stock series: STRC (variable-rate perpetual, 11.5% yield), STRK (fixed 8%, current effective yield ~10.6%), and STRF (fixed 10%). According to Saylor Tracker dashboard, based on the existing BTC reserve, the preferred dividend coverage extends to 48.7 years.
766,970 BTC: A Company's Hoard
Strategy holds 766,970 BTC, worth approximately $54.5 billion, making it the world's largest corporate Bitcoin treasury. The second-largest, Twenty One Capital, holds 43,514 BTC — a 17x gap. The latest purchase occurred on April 6, 2026, adding 4,871 BTC for $329.8 million.
In March, Strategy also registered a $42 billion ATM equity program, split between MSTR common stock and STRC preferred shares. Saylor's capital strategy is tilting toward preferred stock, seeking more durable funding from stable investors.
$14.5B Unrealized Loss and a Cost Basis Gap
The balance sheet shows strain. According to Q1 2026 SEC filings, Strategy's BTC holdings carry an unrealized loss of nearly $14.5 billion. The average purchase price is approximately $75,644 per BTC, while Bitcoin briefly touched $73,000 this week before retreating, currently trading about $5,000 below the average cost.
Supply-side data tells another story: in March, global miners produced roughly 16,200 BTC, while Strategy accumulated 46,233 BTC — nearly three times the new supply. Such aggressive accumulation structurally tightens circulating supply.
In contrast, mining firm MARA Holdings sold 15,133 BTC ($1.1 billion) in March while repurchasing $1 billion in zero-coupon convertibles. CEO Fred Thiel called it a move to boost "financial flexibility" — a starkly different path from Saylor's all-in bet.
Can the Preferred Stock Engine Keep Running?
Saylor stated in April: "The global consensus is that BTC is digital capital. The four-year cycle is dead. Price is now driven by capital flows." This underpins Strategy's business logic. If Bitcoin has indeed evolved from a speculative asset to an institutional one with sustained capital inflows, the 2.05% breakeven ARR becomes a near-unbreachable floor, making the preferred stock engine theoretically self-sustaining.
Yet the logic carries an implicit bet: BTC's long-term annualized return must stay above 2.05%, and demand for Strategy's preferred shares must not collapse during stress periods. The $14.5B unrealized loss and the cost basis gap serve as reminders that this experiment is still underway. "Think bigger" is both a signal and an invitation — to decide whether you believe the math.
