Strategy’s latest Bitcoin accumulation drive has sharpened a long-running debate on Wall Street and in crypto markets: how far investors are willing to fund leveraged Bitcoin exposure through a public company. The company, formerly known as MicroStrategy, has continued to expand its treasury model by issuing common stock, preferred securities and convertible debt, then using the proceeds to buy more Bitcoin. That approach has helped it build one of the largest corporate Bitcoin holdings in the world, but it has also raised questions about the true cost of capital behind those purchases.
The phrase “Strategy buys 66,231 BTC using unusually expensive investor money” captures that tension. The number reflects a period in which the company added tens of thousands of Bitcoin through repeated capital raises, while the “expensive” part refers to the premium, dividend and dilution costs embedded in the securities sold to investors. For supporters, the model is a bold and efficient way to accumulate scarce digital assets. For critics, it is a high-risk financing machine that depends on sustained investor appetite and favorable market conditions.
How Strategy built its latest Bitcoin position
Strategy has spent years transforming itself from an enterprise software company into a Bitcoin treasury vehicle. Its SEC filings show that the company regularly updates investors on both capital raises and Bitcoin purchases, often on a weekly basis. In one filing dated February 24, 2025, Strategy said it acquired 20,356 bitcoins for about $1.99 billion between February 18 and February 23, 2025, at an average price of roughly $97,514 per coin. The company said those purchases were funded with proceeds from a 0% convertible senior notes offering due 2030.
That same filing showed Strategy held 499,096 BTC as of February 23, 2025, acquired for about $33.1 billion at an average purchase price of roughly $66,357 per Bitcoin. The company also disclosed that its assumed diluted share count had risen to 294.1 million from 281.7 million at year-end 2024, underscoring how its Bitcoin strategy is tied to ongoing issuance of equity-linked securities.
By early 2026, the company’s holdings had grown much further. A January 5, 2026 filing showed Strategy held 673,783 BTC as of January 4, 2026, acquired for $50.55 billion at an average price of $75,026 per coin. That filing also showed the company had sold 735,000 shares of MSTR stock for net proceeds of $116.3 million during the final days of 2025, and used ATM equity issuance proceeds to fund Bitcoin purchases.
Taken together, those filings illustrate the mechanics behind the headline. Strategy has not simply bought Bitcoin with excess cash flow from software operations. It has repeatedly tapped public markets, sold securities to investors and converted that capital into Bitcoin. That is why the cost of investor money matters so much to the company’s long-term economics.
Why “unusually expensive investor money” matters
The financing itself is where the story becomes more complex. Strategy has raised capital through several instruments, including common stock, convertible notes and multiple classes of preferred stock. Some of those securities carry explicit dividend obligations. Others embed conversion features or dilution risk that can become costly if the company’s stock underperforms or if market conditions worsen.
In its January 2026 filing, Strategy listed several preferred securities, including STRK, STRD, STRF and STRC, alongside remaining issuance capacity. The filing identified STRK as an 8.00% Series A Perpetual Strike Preferred Stock and STRF and STRD as 10.00% perpetual preferred issues. Those are high headline costs compared with traditional corporate financing, especially for a company whose core operating business has not historically generated enough cash to fund Bitcoin purchases at this scale.
Even when the company issues 0% convertible notes, the money is not truly free. Convertible debt typically includes a conversion premium, meaning investors accept low or zero cash interest in exchange for upside tied to the stock. Strategy’s February 2025 filing said its 2030 convertible notes were issued with a conversion premium of about 35% over the reference trading price of its Class A shares. That structure can reduce immediate cash interest expense, but it still represents a meaningful economic cost if shares later convert or if the company must refinance under less favorable conditions.
Analysts and market observers have described Strategy’s model as reflexive. When Bitcoin rises, Strategy’s equity valuation can expand, allowing it to issue stock or equity-linked securities at attractive terms and buy more Bitcoin. When that premium narrows, however, the same strategy becomes more expensive. Cointelegraph summarized the concern this way in early 2026: when the premium narrows, issuance becomes more expensive, dilution hurts more and each incremental purchase becomes harder to justify.
Strategy buys 66,231 BTC using unusually expensive investor money
The core issue is not whether Strategy can buy Bitcoin. It clearly can, and it has done so at a scale unmatched by most public companies. The issue is whether buying 66,231 BTC through high-cost capital creates long-term value for common shareholders after accounting for dilution, preferred dividends and refinancing risk. That is the central question behind the idea that Strategy buys 66,231 BTC using unusually expensive investor money.
Supporters argue that the company is effectively arbitraging capital markets. If investors are willing to buy Strategy securities at rich valuations or accept lower yields in exchange for Bitcoin-linked upside, management can convert that demand into more Bitcoin per share over time. Strategy itself emphasizes internal metrics such as BTC Yield, BTC Gain and BTC $ Gain to measure whether capital raising has been accretive to shareholders in terms of Bitcoin exposure. In the February 2025 filing, the company reported a year-to-date BTC Yield of 6.9% through February 23, 2025.
Critics see a different picture. They argue that preferred shares with 8% to 10% dividend rates, plus ongoing common stock issuance, amount to expensive funding for a volatile asset. They also note that Strategy’s annual report warns that declines in Bitcoin’s market price can materially affect earnings and the carrying value of its holdings. The company’s 2026 annual report further shows that it has expanded into bitcoin-linked derivative contracts as part of treasury management, a sign that managing liquidity and volatility has become more complex as the balance sheet has grown.
According to Bernstein analysts, cited by The Block in 2025, Strategy has made extensive use of favorable capital market conditions for Bitcoin-related financing, tapping global equity, convertible debt and preference-share markets to scale its holdings. That observation supports the view that the company’s success depends not only on Bitcoin’s price, but also on continued access to investors willing to fund the strategy.
What it means for investors and the broader market
For equity investors, Strategy offers something closer to a leveraged Bitcoin proxy than a conventional software stock. That can be attractive in bull markets, when Bitcoin gains can amplify enthusiasm for the shares and support new issuance. But it also means investors are exposed to several layers of risk at once:
- Bitcoin price volatility
- Equity dilution from ATM offerings and conversions
- Dividend obligations on preferred stock
- Refinancing risk if capital markets tighten
- Potential discounting of the stock relative to net asset value
For preferred investors, the appeal is different. They may be seeking high yields or structured exposure to a company with substantial Bitcoin reserves. Yet those returns are tied to a business model that remains heavily dependent on market confidence. If Bitcoin weakens for a prolonged period, the burden of servicing preferred dividends or rolling over debt could become more visible. That does not mean failure is inevitable, but it does mean the cost of capital is a central variable, not a side issue.
The broader market is also watching because Strategy has become a test case for corporate crypto finance. Its model has influenced how investors think about Bitcoin treasury companies, balance-sheet leverage and the use of public markets to accumulate digital assets. If the model continues to work, more companies may try to replicate it. If it falters, regulators, creditors and shareholders may take a harder look at how such strategies are funded.
Conclusion
Strategy’s Bitcoin strategy remains one of the most closely watched experiments in modern corporate finance. The company has shown that it can raise enormous sums through stock sales, convertible notes and preferred securities, then deploy that capital rapidly into Bitcoin. SEC filings confirm that this approach has driven its holdings from 499,096 BTC in February 2025 to 673,783 BTC by January 4, 2026, with further purchases continuing after that.
But the phrase “Strategy buys 66,231 BTC using unusually expensive investor money” captures the trade-off at the heart of the model. The company is not just making a directional bet on Bitcoin. It is also making a bet that investors will keep funding that bet on terms that remain workable. As long as that demand holds, Strategy may continue to expand its Bitcoin lead. If it weakens, the cost of capital could become the defining constraint on its next move.
Frequently Asked Questions

It refers to the high economic cost of the capital Strategy raises to buy Bitcoin. That includes dilution from stock issuance, conversion features in notes and dividend obligations on preferred shares carrying rates such as 8% and 10%.
How does Strategy fund its Bitcoin purchases?
Strategy funds purchases through a mix of at-the-market common stock sales, convertible debt and preferred stock offerings. Its SEC filings explicitly state that certain Bitcoin purchases were made using proceeds from those offerings.
How many Bitcoin did Strategy hold at the start of 2026?
As of January 4, 2026, Strategy reported holding 673,783 BTC acquired for about $50.55 billion at an average purchase price of $75,026 per coin.
Why do some investors still support the strategy?
Supporters believe Strategy can use strong market demand for its securities to acquire more Bitcoin per share over time. They view the company as a leveraged vehicle for Bitcoin exposure and point to management’s BTC Yield metric as evidence of accretive capital deployment.
What are the biggest risks for shareholders?
The main risks are Bitcoin price declines, dilution from new share issuance, dividend burdens on preferred stock and the possibility that future financing becomes more expensive or unavailable.
