Ethereum Foundation bolsters fiat reserves
The Ethereum Foundation has completed a sale of 5,000 ETH to BitMine Immersion Technologies in an over-the-counter (OTC) transaction valued at approximately $10.2 million. Each ETH was priced at $2,042.96, with the on-chain transfer originating from the Foundation’s multisignature wallet at 0x9fC3dc011b461664c835F2527fffb1169b3C213e. The deal was announced by the Ethereum Foundation on March 14, 2026, marking its second major OTC sale to a corporate buyer within a year.
Proceeds from this sale are earmarked for core operations, including protocol research and development, ecosystem expansion initiatives, and community grant programs. The Foundation’s treasury management framework—introduced in June 2025—calls for periodic conversion of ETH holdings to maintain a fiat-based reserve and targets spending roughly 15% of its treasury annually. On paper, this approach is about stability; in practice, it means regular sales even during volatile market conditions.
The Foundation previously sold 10,000 ETH to SharpLink Gaming in July 2025 at an average price of $2,572.37 per coin.
The Foundation began staking up to 70,000 ETH less than a month ago as part of its operational support strategy, signaling a multi-pronged approach to treasury management that blends both crypto-native and traditional financial tactics.
BitMine’s ETH stash keeps growing
BitMine Immersion Technologies, led by Tom Lee and traded under the ticker BMNR on the NYSE American, has added another 5,000 ETH to its already substantial holdings through this latest deal. As of last week, BitMine held a total of 4,534,563 ETH—valued at roughly $9.41 billion when ETH traded at $2,076. This acquisition follows a recent spree in which BitMine bought 60,976 ETH in just weeks.
Despite these aggressive purchases, BitMine faces significant unrealized losses: the company has invested approximately $16.7 billion into Ethereum but currently sits on about $7.5 billion in unrealized losses due to lower average purchase prices compared to current market value. BMNR stock showed resilience amid these figures, climbing over 5% this week and closing Friday at $20.55 with an intraday range between $20.49 and $22.76.
BitMine’s appetite for ETH remains undiminished despite these paper losses.
OTC sale aims at ecosystem growth
The Ethereum Foundation’s decision to pursue OTC sales instead of open-market transactions is intended to minimize slippage and limit market disruption. This latest transaction is only the second known instance where the Foundation has sold directly to a corporate treasury; the previous deal involved selling 10,000 ETH to SharpLink Gaming in July 2025 at an average price of $2,572.37 per coin—totaling about $25.7 million.
SharpLink now ranks as the second-largest ETH treasury with around $1.75 billion in Ethereum holdings. In contrast to BitMine’s larger position (over four million coins), SharpLink’s more modest holdings underline just how concentrated large-scale ETH reserves have become among a handful of players.

Decentralization mandate, spending in spotlight
Recent months have seen the Ethereum Foundation emphasize its commitment to decentralization principles—including user sovereignty, censorship resistance, open source development, and privacy preservation—across all ecosystem activities. These priorities were outlined in a new mandate released alongside updates about treasury management practices.
According to cointelegraph.com, the Foundation explicitly links these values with its financial strategies: funds raised from asset sales are channeled into protocol R&D and grants aimed at strengthening decentralization and community control within Ethereum’s infrastructure.
Why it matters
For developers and users alike, these moves affect both short-term funding availability for grants and long-term stability for Ethereum’s core operations. The Foundation’s periodic sales—such as July’s 10,000 ETH deal or this March’s 5,000 ETH transaction—highlight an ongoing balancing act between holding native assets and ensuring sufficient fiat reserves for predictable budgeting.
At the time of writing, ETH trades at $2,077.04—down 2.7% over the past 24 hours—reflecting ongoing volatility that complicates large-scale treasury decisions for both buyers like BitMine and sellers like the Foundation.
Uncertainty persists around whether BitMine will continue increasing its exposure given current losses—or if further OTC deals might signal shifting strategies among other major holders seeking liquidity without spooking open markets.
What remains in focus
Market attention now turns to whether the Ethereum Foundation will execute further OTC sales following its March 14, 2026, transaction of 5,000 ETH to BitMine; if additional large-scale sales occur under its treasury management framework, immediate on-chain flows from the Foundation’s multisig wallet would be observable and could impact short-term liquidity.
