Woofun AI reports that Bitcoin-backed preferred stocks have expanded into a $13 billion market in less than two years, driven by Company Strategy and emerging entrant Strive. This rapid growth was highlighted in a June 2026 research report by BitcoinTreasuries.net and DeFi protocol Apyx, which tracked securities issued by listed companies backed by their own BTC holdings. The current market capitalization of these instruments stands at approximately $13 billion, representing nearly 1% of the global $1.3 trillion preferred stock market. Authors of the report project this share will climb to 3% to 5% by 2030, potentially reaching 10% in the long term to equal $1.3 trillion. This financial evolution addresses the core financing challenges for firms holding Bitcoin as treasury assets. Companies like Strategy, under the leadership of Michael Saylor, require long-term capital to acquire more Bitcoin while avoiding the dilution of ordinary shareholders' equity and steering clear of debt with fixed repayment deadlines.

However, achieving this balance is complicated by the sharp fluctuations inherent to Bitcoin prices. Bitcoin peaked at nearly $124,720 in October 2025 before dropping below $60,000 by mid-June 2026, marking a drawdown of around 47% in just eight months.

Preferred stocks provide a structural mechanism to bypass these specific volatility issues. When a company issues preferred stocks, the count of ordinary shares remains static, ensuring existing shareholders avoid equity dilution. These instruments are classified as equity rather than debt, meaning they possess no maturity date and carry no mandatory repayment obligation. In return, holders receive dividends that take precedence over those paid to ordinary shares. For income-focused investors who might otherwise be excluded due to the potential for Bitcoin price increases, this structure effectively transforms Bitcoin's volatility into a stable yield-bearing product. The resulting yields significantly outpace traditional fixed-income markets. The effective yields of the top five Bitcoin-backed preferred securities in the U.S. range from 10.8% to 15.2%, whereas high-yield savings accounts offer only 3% to 4%. Strategy's products dominate this landscape, with the combined market cap of STRF, STRC, STRK, and STRD approaching $12.5 billion.

Meanwhile, Strive, an asset management firm that pivoted into a Bitcoin treasury company, issued its fifth security, SATA, which carries a market cap of about $330 million.

Woofun AI data shows that the fundamental driver of this sector is a massive imbalance where demand far exceeds available supply. Fixed-income institutions, including mutual funds, banks, pensions, and insurance companies, currently hold $10.9 trillion in Treasury bonds. If these entities were to redirect merely 10 to 20 basis points of their capital toward Bitcoin preferred stocks, it would generate demand between $10.9 billion and $21.8 billion, a volume sufficient to support the report's near-term market projections independently.

However, the supply side is strictly constrained by the amount of Bitcoin available to serve as collateral. Of the 20 million BTC in circulation, holdings by exchanges, spot ETFs, and mining companies are excluded because they represent client assets or operational reserves. This leaves only 1.26 million BTC held by corporate treasuries, valued at approximately $83 billion. Strategy alone controls roughly 845,000 BTC, which accounts for 67% of this specific corporate treasury pool.

Safety metrics serve as a critical differentiator in the report's analysis of issuance eligibility. Bitcoin-backed preferred stocks maintain a collateral coverage ratio of 3.8 to 4.5 times, indicating that for every $1 of preferred stock equity, there are 3.8 to 4.5 dollars in Bitcoin backing it. In stark contrast, the median ratio for large bank mortgage loans in the third quarter of 2025 was 0.76 dollars in loans per $1 of property value. Jeff Walton, chief risk officer at Strive, stated in the report that the safety of these tools is significantly higher than that of 95% of bonds in the market because they are backed by real capital rather than future cash flows. Not all companies qualify to issue such securities. Walton outlined strict requirements: a clean balance sheet with no preferentially secured debt, a scale sufficient to support at least $100 million in issuances, and a team experienced in tax treatment, contract design, and dividend policies. He noted that mortgaged Bitcoin takes precedence over preferred stock equity, a factor that hinders most transactions. Strive itself utilized a $225 million issuance of SATA in January to repay debts inherited from its acquisition of Semler Scientific, ensuring all its Bitcoin remained unencumbered.

The risks associated with this asset class are more structural than hidden. Strategy's ordinary stock, MSTR, functions as a volatility amplifier, with its price falling more sharply than Bitcoin over the past year. Tony Lau, an investment partner at Primitive Ventures, described the potential chain reaction in stock prices, noting that when Bitcoin prices drop, Strategy's stock price falls even more. Currently, three out of Strategy's four preferred stocks trade at a par value of less than $100. The ability to pay dividends relies on the company's capacity to continuously raise capital as Bitcoin prices rise, though both Strategy and Strive have disclosed cash reserves sufficient to cover payments for at least 12 months. Phong Le, CEO of Strategy, told investors in February that unless Bitcoin falls to $8,000 and stays there for five to six years, the company's balance sheet will remain strong. The report characterizes the current state of preferred stocks as a "0 to 1 moment" phase, where market demand exceeds what issuers can provide, creating a distinct advantage for companies willing to develop such products.
