"We accelerated purchases into recent market weakness and reiterate our goal of controlling 5% of ETH supply in 2026." — Tom Lee, Chairman, Bitmine Immersion Technologies
Thirty-seven publicly traded companies now hold a combined 7.7 million ETH — approximately 6.4% of Ethereum's 120.7 million circulating supply — according to tracker data as of June 14, 2026. The figure has grown from near zero in mid-2025 to over $13 billion in aggregate value at current prices, making corporate ETH treasuries the fastest-growing category of institutional crypto allocation outside of exchange-traded funds.
Bitmine Immersion Technologies (NYSE: BMNR) dominates the field. The company held 5,672,956 ETH as of June 21, 2026 — 4.7% of total supply — with total crypto, cash, and marketable securities of $10.7 billion. It has staked 4,718,677 ETH through its proprietary MAVAN platform, projecting $230–270 million in annualized staking revenue. The model replicates Strategy Inc.'s (formerly MicroStrategy) Bitcoin treasury playbook — equity and preferred stock issuance funding asset accumulation — but introduces a yield component absent from the BTC version.
The structural question is whether staking income can offset the dilution, preferred dividend obligations, and asset-price risk that define these vehicles. The data so far is mixed.
As of mid-June 2026, the top five public-company ETH holders account for over 95% of the category's total:
| Company | Ticker | ETH Held | Approx. Value | % of ETH Supply | |---|---|---|---|---| | Bitmine Immersion Technologies | BMNR | 5,620,754 | ~$9.7B | 4.66% | | SharpLink Gaming | SBET | 872,984 | ~$1.5B | 0.72% | | The Ether Machine | ETHM | 496,712 | ~$860M | 0.41% | | Galaxy Digital | GLXY | 169,489 | ~$293M | 0.14% | | Bit Digital | BTBT | 158,462 | ~$274M | 0.13% |
Values calculated at $1,733/ETH (Coinbase, June 21, 2026). Bitmine's weekly disclosure on June 21 reported 5,672,956 ETH, reflecting continued accumulation beyond the tracker snapshot.
The corporate ETH treasury phenomenon emerged in mid-2025 when Consensys led a $425 million private placement into SharpLink Gaming, installing Ethereum co-founder Joseph Lubin as chairman. Bitmine followed with its "Alchemy of 5%" initiative, publicly committing to acquire 5% of all ETH. The Ether Machine, founded by former ConsenSys executive Andrew Keys, raised $654 million from Jeffrey Berns of Blockchains Inc. in September 2025. A planned SPAC merger with Dynamix Corporation was later terminated.
The pattern is consistent: legacy small-cap companies pivoting their entire corporate identity toward holding and staking ETH, funded by capital markets rather than operating revenue.
Bitmine's trajectory illustrates the mechanics. The company — originally a small Bitcoin mining operation — began accumulating ETH in late 2025. By December 2025, it held 3.86 million ETH. By June 21, 2026, holdings reached 5,672,956 ETH. The company acquired 52,203 ETH in the week ending June 22 alone, worth approximately $92 million at purchase prices, according to a CoinDesk report citing company filings.
The accumulation has been funded primarily through equity dilution. According to Simply Wall St analysis, Bitmine's shares outstanding increased by more than 286 times over the past year. The company authorized an increase in common stock from 500 million to 50 billion shares — a 100x expansion of the share authorization ceiling. To partially offset dilution concerns, the board approved a $4 billion share repurchase program, among the ten largest buybacks announced in 2026.
In June 2026, Bitmine closed a 3.5-million-share offering of 9.50% Series A Perpetual Preferred Stock (NYSE: BMNP), raising $280 million in gross proceeds. This introduces a $350 million senior claim and 9.50% annual dividend obligation — payable regardless of ETH price performance.
The company launched MAVAN (Made in America VAlidator Network) in March 2026 as a proprietary staking platform. As of June 21, 4,718,677 ETH was staked through MAVAN — roughly 83% of total holdings. Management projects $230–270 million in annualized staking revenue at current yield rates, with plans to open the platform to institutional clients.
The corporate ETH treasury model borrows directly from the Strategy/MicroStrategy playbook for Bitcoin. Strategy holds 847,363 BTC as of June 22, 2026, acquired at an average cost of $66,385 per coin ($33.1 billion total), funded through convertible debt, common stock issuance, and preferred securities.
The ETH version adds structural complexity. Strategy's Bitcoin generates zero yield; it sits in cold storage. Bitmine's staked ETH produces a measurable return — 2.73% on a 7-day annualized basis as of June 21, according to company filings. The network-wide staking rate sits at 3.0–3.5%, according to Ethereum staking data aggregators, with 35.9 million ETH staked by 1.1 million active validators.
However, the cost of capital may exceed the staking yield. Bitmine's 9.50% preferred stock dividend alone requires roughly $33 million annually on the $350 million senior claim. Adding the dilution cost to common shareholders — whose per-share claim on ETH has been reduced by orders of magnitude — the effective cost of capital is substantially higher than the 2.7–3.5% staking yield the ETH generates.
SharpLink presents a marginally different model. The company stakes 100% of its 872,984 ETH and compounds rewards back into the treasury. In May 2026, it launched the Galaxy SharpLink Onchain Yield Fund to pursue yield optimization beyond vanilla staking. The company reports 3.87 ETH per 1,000 shares, up 94% since launch — though this metric reflects share issuance timing as much as ETH accumulation.
The central economic question for ETH treasury companies is whether staking yield covers their all-in cost of capital. A simplified analysis for Bitmine:
Revenue side:
Cost side:
The staking revenue appears to cover the preferred dividend. But the model's viability depends entirely on ETH price stability. A 30% decline in ETH from $1,733 to $1,213 would reduce the dollar value of staking rewards proportionally while preferred obligations remain fixed in dollar terms. A sustained drawdown below Bitmine's average cost basis — which the company does not publicly disclose in a single consolidated figure — could trigger the same reflexive unwind that hit Bitcoin treasury companies in June 2026, when a $62 billion combined market-cap wipeout struck public BTC holders during the decline toward $58,000.
Ethereum-specific risk factors compound the picture. Post-Dencun, the network issues approximately 920,000 net new ETH annually (960,000 issued to stakers minus ~40,000 burned). If corporate treasuries continue accumulating at the current rate — Bitmine alone added over 1.8 million ETH in six months — they absorb the entirety of new issuance and then some, concentrating supply in entities whose selling decisions are governed by equity-market dynamics rather than on-chain utility.
The Bitcoin treasury model provides a direct stress test. With BTC trading near $58,000–$62,000 in late June 2026 — down approximately 51% from its October 2025 high near $126,000 — Strategy's 847,363 BTC position has an unrealized loss relative to peak valuations exceeding $50 billion. The company made its first notable Bitcoin sale (32 BTC) in early June 2026 to cover preferred dividend obligations, breaking its longstanding "never sell" posture.
Corporate BTC holders collectively saw $62 billion in market capitalization erased during the June drawdown, according to CryptoNews. Strategy's funding structure — $8.2 billion in convertible debt and $7.5 billion in preferred stock generating $779 million in annual interest and dividend payments — demonstrates the fixed-cost burden these models carry.
The ETH treasury companies face the same structural risk in a smaller, more volatile asset. ETH traded at $1,670 on June 24 and $1,636 on June 25, according to Fortune, representing a significant decline from 2025 highs. The 37 corporate ETH holders collectively represent forced sellers if equity-market conditions require liquidity — a scenario that could amplify ETH price declines given the concentrated nature of their holdings.
The concentration numbers warrant attention. Bitmine alone holds 4.7% of ETH supply. The top five corporate holders control approximately 6.1%. Combined with the 28.91% of ETH already staked network-wide (35.9 million ETH across 1.1 million validators), a significant fraction of ETH supply is now locked or held by entities with multi-year holding horizons.
From a network-governance perspective, Bitmine's staked ETH (4.72 million) represents approximately 13.2% of all staked ETH on the network. This is a material concentration of validator power in a single corporate entity operating through its proprietary MAVAN platform. While Ethereum's proof-of-stake design distributes attestation duties across validators, the economic influence of a single entity controlling 13% of staked supply introduces questions about network neutrality that the Ethereum community has not yet fully addressed.
The Ethereum Foundation — which cut 54 jobs and 40% of its budget in June 2026, according to separate reporting — does not hold a treasury position comparable to these corporate entities. The Foundation's endowment model operates on a fundamentally different economic basis from the leveraged-accumulation approach of Bitmine and SharpLink.
The corporate ETH treasury phenomenon represents the second iteration of a financial model pioneered by MicroStrategy for Bitcoin: use public-market equity and debt issuance to accumulate a crypto asset, then pitch the company's stock as a leveraged proxy. The Ethereum version adds staking yield as a differentiator — a genuine structural advantage that generates measurable cash flow absent from the BTC model.
The question is arithmetic. At current yields of 2.7–3.5% and ETH prices near $1,700, the staking income is real but modest relative to the cost of capital embedded in 9.50% preferred dividends, 286x share dilution, and the operational expense of running a proprietary validator network. The model works if ETH appreciates. It does not work — and may unwind in the same reflexive manner as BTC treasuries — if ETH declines or stagnates.
The concentration risk is the less-discussed but potentially more consequential variable. A single company controlling 4.7% of ETH supply and 13.2% of staked ETH is an experiment in supply concentration that the crypto market has not previously tested at this scale. Whether this represents rational capital allocation or a fragility vector will depend on market conditions that no treasury model can control.
