Bitmine Extends Lead as Largest Corporate Ethereum Holder with $145M Kraken Purchase
Bitmine Immersion Technologies (Nasdaq: BMNR) purchased 67,111 ETH worth approximately $145 million from crypto exchange Kraken on March 25, further extending its lead as the world's largest corporate holder of Ethereum.
On-chain analyst Lookonchain flagged the transaction within five hours of execution. The implied purchase price works out to roughly $2,160 per ETH, a level well below the asset's August 2025 peak of approximately $4,953. The buy brings Bitmine's estimated total holdings to around 4.66 million ETH, equivalent to about 3.86 percent of Ethereum's entire circulating supply.
A Buying Pattern That Is Accelerating
The March 25 transaction is the largest single weekly purchase Bitmine has made in 2026, but it fits into a clear pattern. Over the preceding three weeks, the company added roughly 61,000 ETH in early March, then approximately 60,999 ETH around March 16, a figure essentially unchanged from the prior week. The pace then stepped up materially: 65,341 ETH around March 23, followed by 67,111 ETH on March 25. The first two tranches were nearly identical in size; the acceleration becomes pronounced only in the third and fourth purchases.
Bitmine chairman Tom Lee, who co-founded the financial research firm Fundstrat Global Advisors, has framed the buying spree as a bet on a market recovery. "Our base case is ETH is in the final stages of the 'mini-crypto winter,'" Lee told CoinDesk on March 23.
He has also pointed to recent geopolitical volatility as a tailwind for crypto. On March 16, Lee cited price performance since the outbreak of armed conflict involving Iran as evidence of crypto's role as a hedge against geopolitical disruption. "Since the start of the Iran war, crypto prices have outperformed and Ethereum has outperformed the S&P 500 by 2,450 basis points," he said.
The strategy carries significant paper losses at current prices. Lookonchain had previously estimated Bitmine's unrealized losses at approximately $4.25 billion when the company held 3.63 million ETH at a higher ETH price. With holdings now at approximately 4.66 million ETH and prices near $2,141, that figure has grown to roughly $7 billion. Bitmine's average acquisition cost stands at approximately $3,997 per ETH.
Modelled on MicroStrategy, Funded by Staking Yield
Bitmine began as a Bitcoin mining company before pivoting to an Ethereum accumulation strategy in 2024 and 2025. The company has publicly stated its goal is to control 5 percent of Ethereum's circulating supply, a model it consciously draws from Strategy Inc. (formerly MicroStrategy), which holds 712,647 Bitcoin.
Unlike a passive holder, Bitmine is generating revenue from its position. The company currently stakes approximately 3.14 million ETH, about 67 percent of its total holdings. At a 7-day network yield of 2.83 percent, that staking activity generates an estimated $184 million in annualized income. Staking refers to locking ETH to help validate transactions on Ethereum's network, in exchange for a share of newly issued tokens and a portion of transaction fees paid by users.
The company is also developing MAVAN, short for Made in America Validator Network, an in-house staking infrastructure platform it plans to launch in the first half of 2026. Bitmine is working with three external staking providers in the interim.
The broader corporate ETH landscape has grown substantially. SharpLink Gaming (Nasdaq: SBET) holds approximately 863,840 ETH (about 0.71 percent of supply). SharpLink's chairman is Joseph Lubin, co-founder of Ethereum, and the company has stated it prioritises yield productivity over raw accumulation, positioning it as a contrast to Bitmine's scale-first approach. The Ether Machine (Nasdaq: ETHM) holds roughly 496,712 ETH, Bit Digital (Nasdaq: BTBT) holds around 153,546 ETH, and Coinbase Global (Nasdaq: COIN) holds approximately 148,715 ETH. The top five corporate holders together control more than 6.1 million ETH, valued above $19 billion.
What This Means for Retail Users in South Asia and Africa
Bitmine's removal of 67,111 ETH from Kraken in a single session is not a trivial supply event. Each large institutional withdrawal reduces the volume of ETH available on exchanges, which can create structural disadvantages during price discovery periods for smaller buyers.
The effect is felt unevenly. India currently leads the 2026 Global Crypto Adoption Index, and South Asia as a region recorded an 80 percent increase in crypto adoption over the past year, with transaction volumes exceeding $300 billion. Pakistan and Bangladesh have also seen growing Ethereum Layer 2 penetration alongside India. Many of those transactions flow through Ethereum Layer 2 networks such as Base and Arbitrum, which offer much lower fees than Ethereum's main chain.
Rising ETH prices driven by institutional treasury accumulation could divert retail DeFi (decentralized finance) activity further toward Layer 2 networks. Readers should note that post-EIP-4844, Layer 2 transaction costs are partly determined by blob fees denominated in ETH. A significant appreciation in ETH's price can therefore raise Layer 2 costs in USD terms even when the ETH-denominated cost remains low, a dynamic that affects collateral and gas economics for DeFi users.
Sub-Saharan Africa has seen stablecoin volumes grow 180 percent year-over-year, driven largely by remittances and cross-border payments. Most of that activity runs on Ethereum-compatible infrastructure. Rising mainnet fees during price surges tend to push African users toward cheaper alternatives, including Layer 2 networks and other EVM-compatible chains such as Polygon. In Nigeria, crypto communities have been closely monitoring ETH/USD price movements amid ongoing naira volatility.
For developers building staking or yield products in India, Kenya, or Nigeria, Bitmine's $184 million annual staking revenue figure provides a useful benchmark. It demonstrates that Ethereum's proof-of-stake mechanism can generate institutional-grade revenue at scale, a data point of growing relevance to those evaluating validator infrastructure investments in these markets.
What Comes Next
Ethereum's network activity reached record highs as recently as March 11, according to CoinDesk, even as mainnet fee revenue has lagged because users have migrated to Layer 2 networks. ETH's market capitalization stands at approximately $233 billion, keeping it in the second position by market cap across all cryptocurrencies.
The company's total assets are valued at approximately $11 billion, including 196 Bitcoin, roughly $1.1 billion in cash, and minority stakes in other companies.
In theory, if ETH prices recover toward Bitmine's average cost basis near $4,000, the company's paper loss position would flip into significant unrealized gains. That scenario could attract further corporate interest in Ethereum as a balance-sheet asset, though this observation reflects editorial analysis rather than a sourced market forecast and would depend heavily on broader market conditions.
