Summary
The Ethereum Foundation completed an over-the-counter sale of 5,000 ETH to BitMine Immersion Technologies, the publicly traded treasury firm chaired by Fundstrat's Tom Lee, in a transaction valued at approximately $10.2 million. The sale cleared at an average price of $2,042.96 per token, according to an announcement by the Foundation on Saturday, March 14, 2026. The Foundation stated that proceeds from the sale will support its core operations, including protocol research and development, ecosystem development, community grant funding, and other activities aligned with its mission to support the Ethereum blockchain.
The sale forms part of the Ethereum Foundation's formal treasury management framework, which aims to balance holdings of ETH against maintaining sufficient fiat or fiat-like assets to cover operating costs. The Foundation targets maintaining annual operating expenses at approximately 15% of total treasury value with a 2.5-year operating buffer—a framework that determines the cadence of ETH sales. The transaction originated from an Ethereum Foundation Safe multisig wallet and is consistent with the organization's ongoing reserve management policy.
BitMine's acquisition continues the company's aggressive Ethereum accumulation strategy, which began when it adopted a dedicated Ethereum treasury strategy in mid-2025. As of the time of the sale announcement, BitMine held approximately 4.53 million ETH, valued at more than $9.4 billion, making it the largest publicly traded Ethereum treasury firm. The company's portfolio is predominantly composed of ETH, though it also holds approximately 195 BTC and over $1 billion in cash, along with equity stakes including a $200 million investment in Beast Industries and a 7% stake in cryptocurrency treasury firm Eightco. Despite unrealized losses estimated around $7.5 billion based on BitMine's average purchase price through late 2025, the company and Chairman Lee have maintained a bullish stance on Ethereum's prospects and continued purchasing during the downturn.
This transaction represents the second direct sale by the Ethereum Foundation to a corporate Ethereum treasury firm. In July 2025, the Foundation sold 10,000 ETH to SharpLink Gaming at an average price of $2,572, generating approximately $25.7 million. SharpLink currently holds the second-largest Ethereum treasury among corporate entities, with holdings valued around $1.75 billion. The pattern of Foundation sales to treasury firms reflects institutional engagement with Ethereum holdings during a period when the asset has declined substantially—falling approximately 58% from its August 2025 peak of $4,946.
