"The broad selloff in crypto, in our view, is a superficial take." — Tom Lee, Chairman, BitMine Immersion Technologies
Public companies now hold 7.5 million ETH — 6.26% of circulating supply — after a 77% growth in token holdings between September 2025 and March 2026. The corporate Ethereum treasury trade, modeled on Strategy's (formerly MicroStrategy) Bitcoin playbook, has produced sharply divergent outcomes: firms accumulated billions in ETH while their stock prices collapsed by as much as 87% from 52-week highs.
Monthly inflows into digital asset treasuries (DATs) plummeted 95% in May 2026, falling from $4.4 billion in April to just $180 million — the lowest figure since October 2024. The compression arrives as ETH trades at $1,666, down from $2,400 in May, while staking yields compress to 2.78% APR across 897,000 validators. VanEck issued a formal warning in its September monthly report that ETH holders face growing dilution risk as the DAT model's sustainability depends on maintaining "volatility-driven funding mechanisms."
CoinGecko tracks 32 institutions holding a combined 7,555,329 ETH worth approximately $12.6 billion at current prices. This represents 6.26% of Ethereum's total supply. The top five holders by ETH count as of June 2026:
| Company | Ticker | ETH Holdings | Approx. Value | |---------|--------|-------------|---------------| | BitMine Immersion Technologies | BMNR | 5,543,872 | $9.2B | | SharpLink Gaming | SBET | 872,984 | $1.45B | | The Ether Machine | ETHM | 496,712 | $828M | | Bit Digital | BTBT | 155,444 | $259M | | Coinbase Global | COIN | 151,175 | $252M |
Between September 2025 and March 2026, Ethereum treasury companies grew collective holdings by 77%, compared to 17.1% growth among Bitcoin treasury companies during the same period. The pace of ETH acquisition by treasury firms — approximately 2.3 million ETH in two months — ran nearly double that seen in comparable Bitcoin accumulation phases, according to CoinMarketCap data.
BitMine Immersion Technologies (NYSE: BMNR), chaired by Fundstrat's Tom Lee, dominates the sector. Originally a Bitcoin mining infrastructure company, BitMine pivoted to an Ethereum treasury strategy in 2025 and now holds 5.54 million ETH — approximately 4.6% of total supply.
The company's 2026 purchase cadence has been aggressive despite falling prices:
BitMine's stated goal is the "Alchemy of 5%" — acquiring 5% of total ETH supply. At 4.6%, the firm is approaching that target. Lee has stated that "this pullback in ETH prices does not reflect the strengthening of Ethereum fundamentals" and predicts ETH will reach $250,000 as corporate validators take over network control.
Against a total invested capital of $18.83 billion, BitMine's ETH position carries an estimated $9.2 billion unrealized loss. The firm reported revenue of just over $6 million alongside losses exceeding $3.8 billion.
BitMine filed with the SEC on June 3, 2026, to offer 3.5 million shares of 9.50% Series A Perpetual Preferred Stock at $80 per share. The sale generated approximately $273.8 million in net proceeds. The preferred stock is listed on NYSE under ticker BMNP.
The structure mirrors Strategy's convertible note and preferred stock issuances used to fund Bitcoin purchases. The 9.5% cumulative annual dividend is paid weekly in cash. Proceeds fund additional ETH purchases, staking infrastructure expansion, and working capital.
SharpLink Gaming (Nasdaq: SBET) followed a similar model. The company reported Q1 2026 revenue of $12.1 million while posting a $685.6 million net loss driven by non-cash unrealized losses and a $191.7 million LsETH impairment. Institutional investors held 46% of SharpLink common stock as of December 2025, and the company is set to join the Russell 2000 Index on June 29, 2026.
The fundamental tension in ETH treasury companies: token balances grew while equity values contracted.
BitMine (BMNR): Trading at approximately $15.90, down 87% from its 52-week high of $160. Analysts have warned the stock is overvalued by more than 11,000% relative to fundamentals.
SharpLink (SBET): ETH per share (ETH Concentration) has doubled from 2.0 to 4.02 since strategy inception in June 2025. Despite this metric improvement, the stock faced pressure from a $685.6 million net loss.
The NAV compression reflects a broader trend. Multiple DATs now trade below their net asset values, including Semler Scientific, Strive, KindlyMD, and Empery Digital. The premium-to-NAV that investors paid during 2024-2025 has compressed back to roughly fair-value pricing or below.
ETH's 33% decline in June 2026 amplified the disconnect. Companies that raised equity capital to buy ETH at $2,000-$2,400 now hold tokens priced at $1,666 — an immediate loss of 17-31% on deployed capital before accounting for issuance costs and dilution.
Staking is the primary economic differentiation between ETH and BTC treasury strategies. BitMine has staked 4.72 million ETH (85% of holdings), primarily via its MAVAN platform. SharpLink has generated 18,800 ETH in staking rewards since June 2025 through native and liquid staking programs.
Current network staking metrics as of June 2026:
At 2.78% APR, BitMine's 4.72 million staked ETH generates approximately 131,216 ETH annually, or $218 million at current prices. This yield offsets the 9.5% preferred dividend obligation ($26 million annually on $273.8 million) but does not address the $9.2 billion unrealized loss.
Staking revenue now accounts for an average of 60% of reported revenue among six treasury companies that disclose staking-related income. Some firms deploy staked ETH into restaking protocols such as EigenLayer, which dominates the sector with $15.3 billion in TVL and 93.9% market share.
Monthly DAT inflows fell 95% from $4.4 billion in April to $180 million in May 2026, according to Cointelegraph. Bitcoin treasuries captured 98% of May's reduced total ($177 million), while non-BTC assets barely registered.
Galaxy Digital argued in its June research note that the "raise-and-hold" era for digital asset treasuries is over. The firm contends that ETF products — which offer comparable exposure without equity dilution risk — have structurally weakened the DAT investment thesis. Spot ETH ETFs provide 1:1 token exposure without the management fees, operational losses, or dilution that accompany the corporate treasury model.
VanEck's analysis reinforced this concern, noting that DAT valuations require continual market turbulence to enable further purchases — what the firm termed "volatility reactors" dependent on a finite "volatility well." When volatility subsides or turns adverse, the funding mechanism breaks down.
The contrast with Strategy (MSTR) is instructive. Strategy holds 845,256 BTC valued at $53.09 billion — and notably, chairman Michael Saylor stated it is "not unlikely" that the company will sell some Bitcoin before end of 2026 to manage financial obligations and dividends. This marked a departure from the firm's long-standing "never sell" stance.
The corporate Ethereum treasury trade has produced the largest concentrated holder of ETH outside of exchanges — BitMine alone controls more ETH than most DeFi protocols lock in total value. The 77% growth in corporate ETH holdings between September 2025 and March 2026 represented the fastest institutional adoption of any crypto asset outside Bitcoin.
The model's sustainability is now in question. The 95% collapse in monthly inflows, 87% stock price declines, and NAV compression below book value suggest the market has repriced the strategy from a growth premium to a discount. The staking yield that differentiates ETH from BTC as a treasury asset generates insufficient returns (2.78% APR) to offset the cost of equity capital deployed (implied by 9.5% preferred dividends and 33%+ unrealized losses).
Whether the ETH treasury model recovers depends on one variable: the price of ETH. If the token returns to $2,400-$4,900 range, unrealized losses reverse and the staking yield story holds. If ETH remains below $2,000, the firms face a structural mismatch between fixed obligations and declining asset values — the same dynamic that collapsed leveraged crypto lenders in 2022.
