Public companies holding crypto on their balance sheets — the so-called "treasury companies" — collectively control more than 1.19 million BTC and 6.58 million ETH as of May 2026, representing over $80 billion in digital assets at current prices. The model, pioneered by Strategy (formerly MicroStrategy) in 2020, has spawned dozens of imitators across Bitcoin, Ethereum, and Solana.
The trade worked when structural scarcity existed: before spot ETFs, before on-chain staking access, before regulated yield products. Those conditions no longer hold. Strategy trades at a mNAV of 1.08x, down from 2.1x in May 2025. BitMine Immersion Technologies (BMNR), the largest public Ethereum treasury, trades at 0.80x book value — a 20% discount. The premium era that defined crypto treasury companies from 2020 through early 2025 is over.
The question is no longer whether these companies can accumulate tokens. It is whether public-market wrappers around crypto assets still create value, or whether they have become an expensive, dilutive layer between investors and the assets they seek to own.
Publicly traded crypto treasury companies reported combined Bitcoin holdings of 1,187,898 BTC as of May 12, 2026, according to BitcoinTreasuries.net. On the Ethereum side, total corporate ETH holdings grew 77% between September 2025 and March 2026 — from 3.7 million to 6.58 million ETH — according to data tracked by Bitcoin Mining Stock.
The sector is heavily concentrated. Strategy holds approximately 843,738 BTC ($69.1 billion at current prices), representing 71% of all publicly tracked corporate Bitcoin. BitMine holds 5.28 million ETH ($11.5 billion), representing 80% of all publicly tracked corporate Ethereum.
Outside these two dominant players, corporate crypto purchases have collapsed. According to CryptoQuant, non-Strategy corporate Bitcoin purchases totaled fewer than 1,000 BTC over the 30 days ending May 18, 2026 — down 99% from their August 2025 peak. Strategy itself purchased 24,869 BTC ($2.01 billion) in the same week, funded almost entirely through STRC preferred stock sales.
The gap between the dominant treasury companies and the rest of the sector has widened to the point where the category is functionally a two-company market.
Strategy's stock closed at $164.85 on May 23, 2026, reflecting a market capitalization of $57.68 billion against Bitcoin holdings worth approximately $69.1 billion. The mNAV ratio — enterprise value relative to the net asset value of Bitcoin holdings — sits at 1.08x.
This is a structural shift. Strategy's mNAV averaged 2.1x in May 2025 and traded as high as 3.4x during the Q4 2024 Bitcoin ETF euphoria. The compression accelerated through H2 2025 and H1 2026 as direct alternatives proliferated. Spot Bitcoin ETFs, which launched in January 2024, now provide institutional investors with lower-cost, lower-fee, tax-efficient exposure to BTC without the equity dilution risk embedded in Strategy's convertible note and ATM issuance model.
The company continues to accumulate aggressively. In Q1 2026, Strategy added 89,599 BTC at an average price of $80,929, generating a 9.4% BTC yield year-to-date and funded by $7.37 billion in at-the-market equity and preferred offerings. Executive Chairman Michael Saylor has stated a target of holding between 5% and 7% of total Bitcoin supply.
Key financial metrics as of late May 2026:
The single-year stock decline of 59% occurred despite Bitcoin itself declining roughly 22% from its August 2025 all-time high — the leverage that once amplified returns now amplifies drawdowns.
BitMine Immersion Technologies holds 5.28 million ETH as of May 17, 2026, representing 4.37% of Ethereum's 120.7 million token circulating supply. Total crypto and cash holdings stand at $12.6 billion, according to the company's most recent 8-K filing with the SEC.
The company trades at $18.88 per share with a market capitalization of $10.75 billion — a 0.80x price-to-book ratio. In plain terms, an investor buying BMNR shares gets $1.25 worth of Ethereum and cash for every $1 spent. The discount has persisted for weeks.
Chairman Tom Lee has acknowledged that the accumulation phase is decelerating. In a May 14, 2026 interview, Lee confirmed that weekly ETH purchases were cut by approximately 74%, noting the firm's "Alchemy of 5%" target could be reached by mid-July at the prior pace. The company now holds 86% of the way toward its stated goal of owning 5% of total ETH supply.
Key financial metrics:
BMNR uplisted from NYSE American to the main New York Stock Exchange board on April 9, 2026, and was added to the preliminary Russell 3000 reconstitution list on May 22, 2026. If the firm qualifies for the Russell 1000 large-cap segment, it would gain access to passive fund flows benchmarked against $12.2 trillion in Russell US Index-linked assets.
The structural case for crypto treasury premiums rested on three pillars, all of which have weakened:
1. Access Scarcity. Before spot ETFs, public equities were the primary vehicle for institutions seeking crypto exposure. That monopoly ended in January 2024 (Bitcoin) and mid-2025 (Ethereum). Investors can now buy direct exposure through ETFs at management fees of 0.15%-0.25%, without equity dilution risk.
2. Leverage Amplification. Treasury companies issued convertible bonds and ATM equity to fund accumulation, offering leveraged crypto exposure. In rising markets, this generated outsized returns. In falling or flat markets, it dilutes existing shareholders. Strategy's share count has increased substantially through ATM programs, and BitMine has similarly financed purchases through direct offerings — including a $400 million raise by peer company SharpLink Gaming (SBET).
3. Tax Arbitrage. Holding crypto through an equity wrapper provided certain tax advantages. Regulatory developments in 2025-2026, including the GENIUS Act's stablecoin framework and the pending CLARITY Act's digital asset classification rules, have progressively reduced these structural advantages by normalizing direct crypto ownership within regulated frameworks.
NYDIG's research, published in late 2025, explicitly warned that crypto treasury premiums would compress as the sector matured. NYDIG global head of research Greg Cipolaro noted that the forces behind compression included "investor anxiety over forthcoming supply unlocks, changing corporate objectives from DAT management teams, tangible increases in share issuance, investor profit-taking, and limited differentiation across treasury strategies." The data through May 2026 has confirmed that thesis in full.
Russell Index inclusion represents one potential mechanism for treasury companies to re-establish value above NAV. FTSE Russell's preliminary 2026 reconstitution list, published May 22, includes BMNR in the Russell 3000. The final index composition takes effect at end of June 2026.
If BMNR's market capitalization qualifies it for the Russell 1000, passive index funds and ETFs benchmarked to that index would be required to purchase shares. According to CryptoSlate, $12.2 trillion in assets are benchmarked against Russell US Indexes, making even a small allocation meaningful for trading volume and price support.
Strategy already sits in the Russell 1000 and the S&P 500. Its inclusion has not prevented NAV discount compression but has maintained institutional liquidity — the stock averages $2.81 billion in daily volume over 30 days.
The index inclusion thesis is testable: if BMNR's discount narrows materially after Russell reconstitution in late June, it would suggest passive flows still create structural demand for crypto treasury equities. If the discount persists, the NAV compression is likely permanent.
One area where Ethereum treasury companies hold a potential structural advantage over Bitcoin treasury companies is staking yield. BitMine stakes 4.7 million of its 5.28 million ETH, generating $289 million in annualized revenue at a 2.80% seven-day yield.
This creates a real cash flow stream that Bitcoin treasury companies cannot replicate. Strategy's Bitcoin holdings generate zero yield; the company depends entirely on BTC price appreciation and financial engineering (convertible notes, ATM equity) to create shareholder value.
Whether staking revenue is sufficient to justify a premium above NAV is an open question. At $289 million annual revenue on a $10.75 billion market cap, BMNR trades at a price-to-staking-revenue ratio of approximately 37x — comparable to mid-range REIT valuations but with significantly higher underlying asset volatility.
Beyond the two dominant players, the crypto treasury landscape in 2026 includes:
The pattern across the sector is consistent: a small number of companies control the vast majority of holdings, while dozens of smaller entrants struggle to achieve meaningful scale or liquidity.
Dilution risk. Ongoing ATM equity programs and convertible note issuances systematically dilute existing shareholders. Both Strategy and BitMine fund acquisitions primarily through equity sales.
Concentration risk. BitMine's 4.37% ownership of ETH supply creates market impact risk. Any forced liquidation — whether through margin calls, regulatory action, or shareholder pressure — could create significant downward price pressure on ETH itself.
Regulatory risk. The pending CLARITY Act includes provisions that could classify certain crypto treasury activities differently for tax and securities purposes. The bill's final text remains in negotiation as of late May 2026.
Correlation risk. Treasury company stocks are beta-amplified versions of the underlying crypto asset. MSTR has declined 59% over the past year while BTC declined roughly 22% — a 2.7x downside leverage ratio.
Yield sustainability. Ethereum staking yields are variable and have trended downward from 4%+ in 2024 to 2.80% in May 2026 as staking participation has increased.
The crypto treasury company model — buy tokens, hold on balance sheet, trade at a premium — depended on structural market conditions that no longer exist. Spot ETFs eliminated access scarcity. Regulated staking and yield products reduced the advantage of equity wrappers. The proliferation of imitators diluted whatever brand premium Strategy once held.
The sector has not collapsed entirely. Strategy and BitMine remain highly liquid, actively traded securities with substantial institutional ownership. BitMine's staking revenue is a real business with real cash flows. Index inclusion creates a floor of passive demand.
But the valuation math has inverted. Both dominant treasury companies now trade at or below the value of their underlying assets. The market is pricing the equity wrapper itself — the management teams, the capital structure, the dilution risk — as a liability, not an asset.
For investors seeking Bitcoin or Ethereum exposure in May 2026, the publicly traded treasury company is no longer the lowest-cost or most efficient option. It may still serve a purpose for investors who need equity-format exposure or who believe staking revenue justifies a premium. For everyone else, the spot ETF provides the same exposure at a fraction of the cost and complexity.
The premium era is over. What replaces it will define the next chapter of corporate crypto strategy.
