"We continue to believe that crypto prices are in the late/final stages of the 'mini-crypto winter.'" — Tom Lee, Executive Chairman, Bitmine Immersion Technologies
Publicly traded companies now hold a combined 6.47 million ETH — approximately 5.4% of total circulating supply — up from near zero 12 months ago. Bitmine Immersion Technologies (NYSE: BMNR), led by Fundstrat co-founder Tom Lee, accounts for 4.66 million of those tokens, or 3.86% of supply, after purchasing 65,341 ETH for $138 million in the week ending March 22. The company's stated target is 5% of total ETH supply.
The ETH corporate treasury sector has reached $19 billion in aggregate holdings across at least 13 publicly traded firms. It represents a direct transplant of the Strategy (formerly MicroStrategy) Bitcoin playbook — raise equity capital, buy crypto, repeat — but with one structural difference: Ethereum generates protocol-level staking yield. That distinction has become the central thesis for ETH treasury proponents and the primary variable that separates the model's economics from its Bitcoin predecessor.
As of March 23, 2026, corporate ETH holdings — including ETFs — account for 7.98% of total Ethereum supply, according to CoinGecko treasury data. Of the 6.47 million ETH held by publicly traded firms, a single entity controls 72%: Bitmine.
This level of concentration has no precedent in the Ethereum ecosystem. Even the Ethereum Foundation, the network's primary steward, holds approximately 270,000 ETH. Bitmine's treasury is 17 times larger.
The three largest ETH treasury firms by holdings:
| Company | Ticker | ETH Held | USD Value | % of Supply | |---------|--------|----------|-----------|-------------| | Bitmine Immersion | BMNR | 4,660,903 | $9.7B | 3.86% | | SharpLink Gaming | SBET | 868,699 | $1.8B | 0.72% | | The Ether Machine | ETHM | 496,712 | $1.0B | 0.41% |
Combined, these three firms hold 6.03 million ETH — 4.99% of total supply — concentrated in the hands of three corporate entities that did not exist as ETH buyers 18 months ago.
Bitmine's ETH accumulation began in June 2025 with a $250 million PIPE (private investment in public equity) round. The company, previously a small Bitcoin mining operation, pivoted entirely to an ETH treasury model under Lee's direction.
The pace has been relentless. Weekly purchase data reported by Bitmine shows escalating acquisition volumes:
The company's total crypto and cash holdings stand at $11.0 billion as of March 22, including 4.66 million ETH, 196 BTC, $1.1 billion in cash, and $283 million in named equity stakes (including a $200 million investment in Beast Industries, MrBeast's platform).
Lee has branded the accumulation target the "Alchemy of 5%" — a goal to hold approximately 6 million ETH, representing 5% of total supply. The company is 77% of the way there after approximately nine months of buying.
The engine driving Bitmine's accumulation is equity dilution. The company has expanded its at-the-market (ATM) equity offering program to $24.5 billion in authorized capacity, facilitated by Cantor Fitzgerald and ThinkEquity. This allows Bitmine to sell shares directly into the market on an ongoing basis, using proceeds to purchase ETH.
The mechanism mirrors Strategy's Bitcoin playbook precisely: issue equity → buy crypto → report larger holdings → attract investors → repeat. Bitmine's share count has expanded to 454.86 million shares outstanding, and its market capitalization stands at $9.67 billion as of March 25.
The company's market cap grew from $15.48 million in January 2025 to $11.57 billion by December 2025 — a 74,634% increase — almost entirely attributable to the treasury pivot and associated capital raises.
A critical metric: Bitmine currently trades at approximately 0.80x book value, according to Seeking Alpha analysis. This represents a 20% discount to NAV — a significant departure from Strategy, which has historically traded at 1.5x to 2.5x its Bitcoin holdings. The sector median for crypto treasury companies sits at 3.64x NAV.
The structural argument for ETH over BTC in a treasury model rests on staking yield. Bitcoin generates zero protocol-level income; Ethereum validators currently earn approximately 3.3% annualized, according to The Block's reference rate data.
Bitmine reports 3,142,643 ETH currently staked — 67% of its total holdings — generating annualized staking revenue of $184 million at current rates. The company projects that once its MAVAN (Made in America Validator Network) is fully operational and all holdings are staked, annual staking income would reach $272 million.
SharpLink Gaming, the second-largest ETH treasury firm, provides a real-world data point on staking economics. The company generated $28.1 million in staking revenue for full-year 2025, up from $3.7 million in 2024 — a sevenfold increase. Q4 2025 staking revenue alone was $15.3 million, up nearly 50% from Q3.
However, SharpLink's full-year 2025 results also illustrate the model's fragility. The company reported a net loss of $734.6 million, driven by $616.2 million in unrealized losses on ETH price declines and a $140.2 million impairment charge on liquid staking positions. Staking revenue of $28.1 million offset approximately 3.8% of total losses.
The math is unforgiving: at 3.3% staking yield, ETH must not decline by more than 3.3% annually for staking revenue to produce a positive return. ETH traded at approximately $3,500 in mid-2025 and sits near $2,072 as of March 22, 2026 — a 41% decline. No amount of staking yield compensates for drawdowns of that magnitude.
The ETH treasury sector has attracted a diverse set of entrants:
SharpLink Gaming (SBET): Chaired by Ethereum co-founder Joseph Lubin, SharpLink holds 868,699 ETH with 95% staked. The company raised $3.2 billion in capital during 2025 and doubled its ETH-per-share metric to 4.01. Institutional ownership surged from 6% to 46% by year-end 2025.
The Ether Machine (ETHM): Formed through a SPAC combination with Dynamix Corporation, The Ether Machine holds 496,712 ETH. It received a $654 million ETH contribution from Blockchains Inc. founder Jeffrey Berns. The company generates returns through staking, restaking, and DeFi participation.
Others: At least 10 additional publicly traded companies hold smaller ETH positions, including BTCS, Fundamental Global, Intchains, and GameSquare, per CoinGecko treasury tracking data.
The sector's combined capital raising capacity exceeds $30 billion when including all authorized ATM programs — a figure that dwarfs the total daily trading volume of ETH on most centralized exchanges.
The MicroStrategy/Strategy playbook depends on a persistent market-to-NAV premium. When a company's stock trades above the value of its underlying crypto holdings, each equity issuance is accretive: the company raises more dollars per share than the crypto it could buy is worth, effectively acquiring crypto at a discount.
When the premium compresses below 1.0x, the flywheel reverses. Each share sold dilutes existing holders without proportionate crypto acquisition.
Bitmine trades at 0.80x NAV. This means the company is currently issuing equity at a discount to its underlying ETH holdings — every new share sold dilutes existing shareholders' claim on the treasury. For comparison, Strategy (MSTR) maintains a premium ranging from 1.5x to 2.5x NAV on its Bitcoin holdings.
According to VanEck's analysis, Strategy's own economics show diminishing returns: in August 2021, the company needed 2.6 BTC to generate one basis point of Bitcoin yield. By May 2025, that figure had ballooned to 58 BTC, with the capital required rising from $126,000 to $5.5 million for the same unit of yield. Strategy's annual interest payments are projected to reach $87 million by 2026, with preferred stock dividends expected at $904 million.
ETH treasury companies face the same dynamic, compounded by ETH's deeper price drawdown relative to Bitcoin over the trailing 12 months.
Three data points define the current state of the ETH treasury sector:
1. Concentration is extreme. One company controls 72% of all corporate ETH holdings. Three companies control 93%. This is not a broad institutional adoption trend — it is a small number of entities executing a leveraged bet on ETH price appreciation and staking yield.
2. Staking yield does not offset capital losses. At a 3.3% annualized yield, a 41% ETH price decline since mid-2025 requires approximately 12 years of staking returns to recover — assuming no further drawdown. SharpLink's 2025 results confirm this: $28.1 million in staking revenue against $734.6 million in total losses.
3. The funding model is under stress. Bitmine's sub-1.0x NAV multiple means equity issuance is dilutive at current prices. The $24.5 billion ATM program provides capacity, but deploying it at these multiples transfers value from existing shareholders to new buyers and, indirectly, to ETH sellers.
The ETH corporate treasury model is a leveraged bet dressed in institutional clothing. The staking yield thesis provides a narrative edge over Bitcoin treasuries, but the arithmetic is clear: at current yield levels, staking revenue is a rounding error relative to the capital at risk.
Bitmine's 3.86% supply concentration raises secondary questions about market impact — both on the way up and, potentially, on the way down. The company's ability to continue accumulating depends on equity issuance in a market where its stock trades below book value. That tension — between the stated goal of 5% supply ownership and the economics of issuing dilutive equity to get there — is the central unresolved question for the sector.
The data does not support a conclusion that staking yield alone justifies the capital structure. It does support a conclusion that a small number of public companies have accumulated a systemically significant share of Ethereum's supply in under a year, funded primarily by retail and institutional equity buyers. Whether that accumulation creates or destroys shareholder value depends almost entirely on the direction of ETH prices — a variable none of these companies control.
