"There is no pressure to sell any ETH at these levels, because there are no debt covenants or other restrictions. BitMine is in a position to ride out crypto volatility while earning recurring income and staking rewards." — Thomas Lee, Chairman, BitMine Immersion Technologies
Corporate Ethereum treasuries added 2.88 million ETH in the six months ending March 2026, lifting aggregate public-company holdings to 6.47 million tokens — a 77% increase from September 2025. The acceleration is overwhelmingly concentrated in one firm: BitMine Immersion Technologies (BMNR), which now holds 4.73 million ETH (3.92% of total supply) after purchasing 71,179 ETH last week alone — its largest weekly buy of 2026.
Simultaneously, the Ethereum Foundation executed a record $46.2 million staking deposit on March 30, advancing its plan to stake 70,000 ETH from its 172,650 ETH treasury. The shift from periodic ETH sales to yield-generating staking marks a structural change in how the network's steward funds operations. These two developments — corporate accumulation and foundation staking — are rewriting the ownership and governance dynamics of the Ethereum network at a time when ETH trades near $2,070, down roughly 58% from its August 2025 peak near $5,000.
Publicly traded companies collectively held 6,468,808 ETH as of late February 2026, according to data aggregated by CoinGecko and bitcoinminingstock.io. At current prices (~$2,070), that positions corporate ETH treasuries at approximately $13.4 billion.
The top holders by ETH balance:
| Company | Ticker | ETH Holdings | Approx. Value | % of ETH Supply | |---------|--------|-------------|---------------|-----------------| | BitMine Immersion Technologies | BMNR | 4,732,082 | $9.8B | 3.92% | | SharpLink Gaming | SBET | ~863,424 | $1.8B | 0.72% | | Bit Digital | BTBT | ~120,306 | $249M | 0.10% | | BTCS Inc | BTCS | ~70,028 | $145M | 0.06% |
BitMine alone accounts for 73% of all publicly reported corporate ETH holdings. The concentration is without precedent in the Ethereum ecosystem.
Growth from September 2025 to March 2026 — from 3.7 million to 6.47 million ETH — occurred almost entirely during a period of declining prices. ETH fell from approximately $3,800 in September 2025 to $2,070 at the time of writing, meaning these firms were accumulating into a 45% drawdown.
BitMine Immersion Technologies, chaired by Fundstrat Global Advisors co-founder Tom Lee, has adopted a treasury model directly analogous to Strategy Inc.'s (formerly MicroStrategy) bitcoin accumulation framework. The numbers tell the story:
The paper losses are severe. In early February 2026, when ETH briefly traded below $2,000, BitMine sat on an estimated $8 billion unrealized deficit, according to CoinDesk reporting. BMNR shares have fallen 88% from their July 2025 peak.
Lee has maintained the position is by design. "BitMine's $6 billion ether paper loss is 'by design,'" he stated in February, according to CoinDesk, pointing to the absence of debt covenants and the company's staking income as reasons to hold through the drawdown.
The weekly buying cadence has not slowed. March 2026 purchases:
BitMine's proprietary staking infrastructure — the Made in America Validator Network (MAVAN) — launched in Q1 2026, designed to internalize validator operations and improve yield capture.
On March 30, 2026, the Ethereum Foundation deposited approximately 21,500 ETH ($46.2 million) into the Beacon Chain via eleven transactions — its largest single staking event. The deposit accelerates a strategy outlined in February to stake up to 70,000 ETH from its treasury.
Key details of the EF staking program:
The move represents a structural shift. For years, the EF funded operations — protocol research, ecosystem grants, developer support — through periodic ETH sales, a practice that drew sustained community criticism for creating sell pressure on the asset. The new approach generates yield without reducing the treasury balance.
According to The Block, projected annual yields from the full 70,000 ETH target range from 1,900 to 2,200 ETH, depending on network conditions. At current prices, that translates to roughly $3.9 million to $4.6 million in annual operational funding from staking alone.
The EF retains approximately 147,400 ETH ($303 million) in its treasury beyond the staking allocation, according to CoinDesk.
Total staked ETH on the Beacon Chain has reached 35.86 million tokens, or 28.91% of circulating supply, according to current network data. The CoinDesk Composite Ether Staking Rate (CESR) — the standardized benchmark for institutional staking products — shows an annualized yield of approximately 2.7% to 3.3%, varying with network activity and validator count.
The economic calculus for treasury holders:
| Entity | Staked ETH | Est. Annual Yield (ETH) | Est. Annual Yield (USD) | |--------|-----------|------------------------|------------------------| | BitMine | 3,142,643 | ~84,852 | ~$177M | | Ethereum Foundation | 70,000 (target) | ~1,900–2,200 | ~$3.9M–$4.6M | | SharpLink Gaming | Undisclosed portion | ~5,671 (earned to date) | ~$11.7M (to date) |
Staking income creates a structural floor under treasury operations. Even during severe price declines, staked ETH generates protocol-level rewards that offset operational costs. This mirrors the logic of holding dividend-paying equity through a drawdown — the income stream persists independent of mark-to-market losses.
For institutional allocators, the CESR benchmark has become a reference rate. As CoinDesk's Opinion section noted on March 24, 2026, "cautious TradFi firms love staked ether" precisely because the yield is protocol-embedded, not dependent on counterparty credit risk.
The divergence between bitcoin and ether corporate treasury strategies sharpened last week. Strategy Inc. (MSTR) — which holds 762,099 BTC at an average cost of $75,694 — paused its buying after 13 consecutive weeks of accumulation. Executive Chairman Michael Saylor skipped his customary Sunday "Orange Dot" purchase signal on X, instead promoting the company's new preferred equity offering (STRC).
Strategy filed a $42 billion at-the-market equity program on March 23 — split between $21 billion in MSTR common stock and $21 billion in STRC preferred shares — signaling a shift in financing strategy rather than a retreat from bitcoin, according to CoinDesk.
Meanwhile, BitMine accelerated. Its 71,179 ETH purchase last week was its largest of 2026. The firm has maintained a consecutive weekly buying streak even as Strategy's ended.
The contrast highlights a structural difference between BTC and ETH treasury models. Bitcoin treasuries generate no native yield; their thesis is pure price appreciation. Ether treasuries earn staking rewards, providing an income stream that partially offsets holding-period risk. BitMine's $177 million annualized staking revenue makes the ETH treasury model cash-flow positive at the protocol level, even as the underlying asset depreciates.
The concentration of ETH holdings raises governance and market-structure questions. BitMine's 3.92% of total supply is the largest known single-entity position in Ethereum history. Combined with the EF's 172,650 ETH (0.14%) and SharpLink's ~863,424 ETH (0.72%), the top three identifiable institutional holders control approximately 4.78% of all ETH.
If these entities stake the majority of their holdings — as BitMine already does with 66% — they represent a meaningful share of network validation. Total staked supply stands at 35.86 million ETH. BitMine's 3.14 million staked tokens alone represent 8.8% of all staked ETH.
This creates potential concerns:
These are not theoretical concerns. In February, when ETH briefly dipped below $2,000 and BitMine's unrealized losses exceeded $8 billion, BMNR shares traded at $3.20 — an 88% decline from peak. The stock has since recovered to approximately $18.50, but the episode demonstrated the reflexive risk when a levered treasury vehicle faces margin pressure.
The Ethereum network is experiencing a structural ownership shift. Corporate treasuries — led by a single dominant buyer — have absorbed nearly 5.4% of total ETH supply. Simultaneously, the Ethereum Foundation is transitioning from a net seller to a yield-generating staker, aligning its incentives more closely with network health.
The staking yield mechanism makes ETH corporate treasuries fundamentally different from their BTC counterparts. BitMine generates $177 million in annual staking income even while sitting on billions in paper losses. The Ethereum Foundation will generate roughly $4 million annually from its staking target, reducing its need for market sales.
Whether this concentration improves Ethereum's long-term stability — by creating committed, long-horizon holders — or introduces systemic risk through single-entity dominance remains the open question. The data shows ownership consolidating and circulating supply contracting. Markets will price the implications accordingly.
