The Ethereum Foundation moved 5,000 ETH to BitMine Immersion Technologies in an over-the-counter sale worth about $10.2 million, with the transaction executed between March 14 and March 16, 2026 at an average price of $2,042.96 per ETH. The deal shows how major crypto institutions are increasingly relying on private block trades to manage treasury exposure without using public exchange order books.

The sale was carried out under the treasury framework the Foundation introduced in June 2025, which allows for periodic conversions of Ethereum into fiat to maintain operating reserves. The transaction was not presented as an isolated liquidation, but as part of a broader treasury policy designed to preserve financial runway while continuing to fund the Foundation’s long-term work.

Treasury Strategy Is Now Driving Execution Choices

Under that framework, the Foundation targets annual spending equal to roughly 15% of treasury holdings in order to sustain a multi-year operating horizon. That policy links asset sales directly to operational planning, rather than leaving treasury decisions to ad hoc market timing.

The Foundation has paired that reserve-management approach with a broader institutional mandate centered on decentralization, open-source development, protocol security, and developer tooling. Its treasury activity is therefore being positioned as a mechanism to fund stewardship objectives while reducing governance concentration over time.

This was not the first sizable ETH transfer carried out under that strategy. The Foundation had previously sold 10,000 ETH to SharpLink Gaming in July 2025, while still retaining a substantial balance reported at around 170,000 ETH.

At the same time, the Foundation is not only selling Ether but also preparing to deploy part of its holdings into infrastructure. Its plan to place about 70,000 ETH into validator nodes shows that treasury management is being balanced between fiat conversion and long-term staking commitments.

BitMine’s Role Adds an Institutional Dimension

BitMine, which is listed on the NYSE American under the ticker BMNR, used the transaction to deepen its Ether position as part of a much larger accumulation strategy. The buyer is not acting as a passive counterparty, but as a corporate holder building a multi-million ETH reserve.

The report tied that positioning to BitMine’s broader market profile, including holdings above 4.5 million ETH and the visibility that comes from having Fundstrat co-founder Tom Lee as chairman. That combination turns BitMine into more than a purchaser of treasury inventory, making it a prominent institutional proxy for Ethereum exposure.

The choice to execute the trade over the counter reflects the priorities of both sides. OTC execution offers price certainty, lower slippage, and less visible market disruption when large positions need to change hands.

That preference is becoming more common across the market. The cited data showing crypto spot OTC volumes rising 109% year over year in 2025, far above the roughly 9% growth in major centralized exchange spot volumes, suggests that large transfers are increasingly being pushed away from lit venues.

The Trade Also Raises Governance and Compliance Questions

For compliance teams and institutional counterparties, the transaction highlights several practical issues at once. Large private sales by ecosystem stewards require clear recordkeeping, auditable disclosure practices, strong OTC counterparty due diligence, and governance approval structures that can withstand outside scrutiny.

The Foundation’s sale to BitMine therefore works as more than a treasury event. It is also a reminder that as foundations and major holders adopt more institutional trading practices, they face higher expectations around transparency, settlement controls, and the alignment between treasury decisions and stewardship responsibilities.
