Public companies now hold approximately 1.16 million BTC across 197 listed firms, according to BitcoinTreasuries.net — more than 5% of Bitcoin's total supply. Strategy Inc.

"MSTR's engine rests largely on repeatedly issuing shares at a premium over the per share net asset value of its bitcoin holdings, with proceeds immediately deployed to buy more. So long as the premium holds, each issuance is arithmetically accretive to NAV—an internal arbitrage in which new shareholders subsidize existing ones." — Henry T. C.

Public companies now hold approximately 1.16 million BTC across 197 listed firms, according to BitcoinTreasuries.net — more than 5% of Bitcoin's total supply. Strategy Inc. (MSTR) alone accounts for roughly 840,000 of those coins, a position acquired for $63.4 billion. Yet MSTR's market capitalization stands at $47.1 billion, implying the market values the company at a discount to its Bitcoin holdings for much of 2026.
The corporate Bitcoin treasury model, pioneered by Michael Saylor in August 2020 with a $250 million purchase, has entered a stress-test phase. Forty percent of publicly traded Bitcoin treasury firms now trade below their net asset value. MARA Holdings liquidated 23,093 BTC ($1.63 billion) in H1 2026 to retire debt. Twenty One Capital's founding CEO departed after a failed three-way merger. Meanwhile, Strive and Metaplanet continue aggressive accumulation. The sector is bifurcating into survivors and liabilities.
As of August 2026, 197 public companies hold Bitcoin on their balance sheets, according to BitcoinTreasuries.net. Collective holdings total approximately 1.16 million BTC, representing over 5% of Bitcoin's 21-million-coin hard cap. The top five holders control the vast majority of that supply:
| Rank | Company | Ticker | BTC Holdings | Approx. Value | |------|---------|--------|-------------|---------------| | 1 | Strategy Inc. | MSTR | ~843,775 | $66.7B | | 2 | Twenty One Capital | XXI | 43,514 | $3.4B | | 3 | Metaplanet | 3350.T | ~43,000 | $3.4B | | 4 | MARA Holdings | MARA | 35,577 | $2.8B | | 5 | Bullish | BLSH | 24,300 | $1.9B |
Strategy's dominance is stark. The company holds approximately 73% of all publicly listed corporate Bitcoin. In 2025, according to KuCoin Research, Strategy accounted for 97.5% of net new corporate Bitcoin purchases. The concentration risk is structural: the corporate Bitcoin treasury sector is, for practical purposes, a single-company trade.
Strategy's position as of August 10, 2026: 843,775 BTC acquired at a total cost basis of $63.36 billion, yielding a per-coin average cost of approximately $75,385. At Bitcoin's price near $79,000 in late August, the position is modestly in the money — a reversal from earlier in 2026 when Bitcoin's dip below $65,000 put Strategy underwater.
The company's capital-raising apparatus is industrial-scale. Year-to-date through Q2, Strategy raised $17 billion across equity and fixed-income instruments. Between August 17-23 alone, Strategy sold 18.26 million MSTR shares for $2.01 billion. Of those proceeds, $300 million went to a USD reserve (now $5.1 billion total), $136.4 million was used to repurchase 1.43 million preferred shares (STRC), and $1.59 billion was allocated to a new USD cash pool.
The broader capital plan targets $42 billion in equity and $42 billion in fixed income over three years — $84 billion total. As of Q2, long-term debt stood at $6.7 billion and preferred equity at $14.4 billion.
MSTR's stock price tells a more complicated story. Trading at $122.60 with a market cap of $47.1 billion, the stock's 52-week range spans $81.81 to $365.21. The mNAV — the ratio of market capitalization to the value of underlying Bitcoin — fell to 0.68x on August 3, 2026, according to mNAV.com, down from 3.4x in November 2024. By late August, following Bitcoin's rally to $80,000, mNAV recovered to approximately 1.01x.
The compression from 3.4x to near parity represents the market's repricing of what, precisely, Strategy's equity structure adds beyond a Bitcoin ETF.
Metaplanet (3350.T) — the Tokyo-listed firm dubbed "Asia's MicroStrategy" — purchased 5,075 BTC in Q1 2026 alone, bringing total holdings to 40,177 BTC at a cumulative cost of $3.92 billion. Under its "555 Million Plan," the company targets 100,000 BTC by end-2026 and 210,000 BTC by 2027. Metaplanet funds purchases through equity raises, debt management, and options trading against its existing Bitcoin stack.
The strategy carries execution risk. According to CoinDesk, Metaplanet's average purchase price sits near $107,000 per coin for a significant portion of its holdings, generating large unrealized losses at current prices. As of August 25, Metaplanet held approximately 43,000 BTC.
Twenty One Capital (XXI) began trading on the NYSE after merging with Cantor Equity Partners, launching with 43,514 BTC worth approximately $3.9 billion. Tether was the majority holder. In April 2026, Tether proposed a three-way merger of XXI, Strike, and Elektron Energy to create an integrated Bitcoin company combining treasury, mining, financial services, and capital markets.
The deal collapsed. In July, co-founder and CEO Jack Mallers resigned citing "strategic disagreement" with the board. XXI stock fell 18% on the announcement. Raphael Zagury now leads the company, which retains 43,514 BTC valued at roughly $3.4 billion. The episode illustrates the governance risk inherent in entities whose strategy reduces to "hold one asset."
Strive (ASST) — founded by Vivek Ramaswamy — holds 21,356 BTC as of August 21, 2026, making it the seventh-largest public holder. The company purchased 1,110 BTC for $81.5 million during August 17-21 at an average price of $73,409. Strive differentiated itself by eliminating all debt in Q1 2026 and launching what it claims is the first U.S. listed security paying daily cash dividends: its Variable Rate Series A Perpetual Preferred Stock (SATA), which began daily payouts on June 16 at a 13% annualized rate, funded by income from its Bitcoin treasury operations.
MARA Holdings' trajectory illustrates the model's fragility under financial stress. The Bitcoin miner sold 23,093 BTC for approximately $1.63 billion during H1 2026, at an average of roughly $70,631 per coin, according to Blockspace. Holdings fell from 53,822 BTC at year-end 2025 to 35,577 BTC by June 30.
MARA used a significant portion of Q1 proceeds to repurchase approximately $1 billion of its 0% convertible senior notes, cutting total debt from $3.6 billion to roughly $2.4 billion. The company also pivoted resources toward AI infrastructure — a pattern documented across the mining sector.
The sales represent a policy reversal. MARA previously operated under a "HODL" mandate, retaining all mined Bitcoin. In 2026, the company expanded its treasury policy to permit sales of Bitcoin already on the balance sheet, citing the need to fund operations, pursue growth opportunities, and manage liquidity.
By early 2026, approximately 40% of the largest publicly traded Bitcoin treasury firms traded below their NAV, according to Cryptopolitan. The dynamic is structurally destructive: once shares trade at or below NAV, every new equity raise dilutes existing shareholders. The company issues shares at a discount, buys Bitcoin it could have acquired more efficiently without the corporate intermediary, and destroys value in the process.
Strategy's mNAV trajectory captures this phenomenon at scale. At 3.4x in late 2024, every dollar of equity issued purchased $3.40 worth of Bitcoin exposure for existing shareholders — a positive feedback loop that Saylor termed a "NAV premium engine." At 0.68x — the August 3, 2026 trough — each issuance was dilutive. The model's logic inverts below 1.0x.
The premium compression coincided with the maturation of spot Bitcoin ETFs, which offer direct BTC exposure without corporate governance overhead, management risk, or capital structure complexity. The iShares Bitcoin Trust (IBIT) charges 0.25% annually. MSTR carries billions in preferred equity obligations, convertible debt service, and operating costs for a software business that generates minimal revenue relative to the balance sheet.
The University of Texas Law School published what it describes as the first academic study of the Bitcoin treasury model in June 2026. Professor Henry T. C. Hu's paper, published in the Journal of Corporation Law and subsequently discussed on the Harvard Law School Forum on Corporate Governance, introduced two frameworks.
First, "corporate omphaloskepsis" — the firm gazes inward at two metrics (Bitcoin price and its NAV premium) to the exclusion of external economic contribution. The outside world matters only insofar as it moves those two numbers.
Second, "polypharmacy of financial risk" — the layering of leverage instruments (convertible notes, at-the-market equity, preferred stock, secured credit facilities) creates compounding risk vectors that are difficult for shareholders to disentangle. Bitcoin's five-percent daily value-at-risk is -5.01%, more than 125 times the -0.04% VaR of a 3-month Treasury bill, according to The Regulatory Review.
The paper notes that Strategy, holding approximately 4% of all Bitcoin, issued more equity capital in 2025 than any other U.S. public company. The implication: the model's scale has grown to a point where forced liquidation under financial distress could itself move Bitcoin's price — a reflexivity problem that grows with the position.
The surviving treasury companies are differentiating through increasingly complex capital structures:
Strategy runs a multi-instrument approach: common equity (MSTR), preferred stock (STRC) with an 8% annual rate, convertible notes, and a newly created USD cash pool. Total preferred equity: $14.4 billion. Total long-term debt: $6.7 billion. Cash reserves: $5.1 billion.
Strive takes the opposite approach — zero debt, daily-paying preferred stock funded by Bitcoin-derived income, and equity-funded BTC purchases. Its 13% annualized rate on SATA implies significant yield-generation activity atop its 21,356 BTC stack.
Metaplanet uses options trading against its existing holdings as an income source, alongside equity raises and debt management. The model attempts to generate cash flow from an otherwise non-productive asset.
Each structure represents a different bet on how to justify a corporate wrapper around a commodity holding. The market has not yet determined which, if any, merits a premium.
The corporate Bitcoin treasury sector has entered a Darwinian phase. The conditions that powered its growth — persistent NAV premiums, cheap capital, and limited alternatives for regulated Bitcoin exposure — have each deteriorated. Spot Bitcoin ETFs offer cheaper, cleaner exposure. NAV premiums have compressed toward or below parity. Capital costs are rising.
Strategy's position is too large to unwind without market impact, a fact that Professor Hu's analysis identifies as a systemic concern. Metaplanet's cost basis above $100,000 per coin on portions of its stack leaves it vulnerable to any sustained price decline. MARA's forced selling demonstrates what happens when leveraged models meet adverse conditions.
The companies that survive will likely be those generating real yield from their Bitcoin holdings — Strive's daily dividends and Metaplanet's options income represent early attempts. The rest face a structural question the market is already pricing in: if you trade at or below NAV, why do you exist when a spot ETF charges 25 basis points?
