Bitcoin-Backed Preferred Shares Emerge as the Go-To Capital Tool for Crypto Treasury Companies

A new category of Wall Street financial instruments has quietly transformed from a niche experiment into a multibillion-dollar market segment in less than two years. According to a June 2026 research report published by BitcoinTreasuries.net in collaboration with DeFi protocol Apyx, this growth trajectory is far from over.

The report focuses on preferred shares issued by publicly traded companies that hold bitcoin as a primary treasury asset. As of mid-2026, these securities carry a combined market value of approximately $13 billion — representing close to 1% of the $1.3 trillion global preferred share market. The report's authors anticipate that figure climbing to between 3% and 5% by 2030, with a longer-term potential of 10%, or roughly $130 billion.

The appeal of this financing structure stems from a fundamental challenge facing bitcoin treasury companies. Firms like Strategy, helmed by Michael Saylor, require long-duration capital to continue accumulating bitcoin without diluting existing shareholders or taking on traditional debt obligations with fixed repayment schedules. Bitcoin's notorious price volatility makes that balancing act particularly demanding. The asset traded near $124,720 in October 2025 before sliding below $60,000 by mid-June 2026 — a drawdown of approximately 47% over eight months.

Preferred shares offer an elegant workaround. Issuing them does not increase a company's common share count, preserving value for existing holders. Because they are classified as equity rather than debt, there is no maturity date and no mandatory repayment. In return, preferred shareholders receive dividends that take priority over common stock distributions. For income-focused investors unable to participate directly in bitcoin's price appreciation, this structure converts crypto volatility into a yield-bearing product.

The yields on offer are dramatically higher than conventional fixed-income alternatives. The five primary bitcoin-backed preferred securities currently trading in the U.S. carry effective yields ranging from 10.8% to 15.2%, compared to the 3% to 4% typically offered by high-yield savings accounts.

Strategy dominates this emerging market. Its four preferred securities — STRF, STRC, STRK, and STRD — collectively represent a market value of approximately $12.5 billion. Strive, an asset manager that has repositioned itself as a bitcoin treasury company, issued a fifth instrument, SATA, with a current market value of around $330 million.

The report's core argument centers on a supply-demand imbalance. Fixed-income institutions including mutual funds, banks, pension funds, and insurance companies hold a combined $10.9 trillion in U.S. Treasuries. Even a modest reallocation of 10 to 20 basis points from that pool would generate between $10.9 billion and $21.8 billion in fresh demand — enough on its own to validate near-term market growth projections.

However, supply is constrained by the availability of bitcoin as collateral. Of the roughly 20 million bitcoins in circulation, those held on exchanges, in spot ETFs, or by mining firms are excluded as customer assets or operational reserves. That narrows the eligible pool to approximately 1.26 million bitcoins held in corporate treasuries, valued at around $83 billion. Strategy alone controls about 845,000 of those, or 67% of the total.

Collateral coverage ratios are cited as a key safety feature. Bitcoin-backed preferreds maintain coverage ratios of 3.8 to 4.5 times, meaning issuers hold between $3.80 and $4.50 in bitcoin for every $1 of preferred equity outstanding. For context, the median large-bank mortgage in Q3 2025 advanced just 76 cents per dollar of home value. Jeff Walton, Chief Risk Officer at Strive, stated in the report that these instruments offer significantly higher security than 95% of bonds currently on the market, precisely because they are backed by actual capital rather than projected future cash flows.

Not every bitcoin-holding company qualifies as an issuer, however. Walton outlined strict prerequisites: a balance sheet free of senior secured debt, sufficient scale to support an issuance of $100 million or more, and internal expertise covering tax treatment, covenant design, and dividend policy. Strive itself used its $225 million SATA offering in January 2026 to retire debt acquired through its purchase of Semler Scientific, leaving its entire bitcoin holdings unencumbered.

Risks remain real and structural. Strategy's common stock has historically amplified bitcoin's downside moves, falling more sharply than the underlying asset during market corrections. Three of the company's four preferred securities currently trade below their $100 par value. Dividend sustainability also depends on continued capital-raising capacity against an appreciating bitcoin price — though both Strategy and Strive have disclosed cash reserves considered sufficient to meet near-term obligations.
