The Ethereum Foundation has finalized the sale of 5,000 Ether (ETH) to BitMine Immersion Technologies through an over-the-counter transaction, a deal worth roughly $10.2 million. The sale price was set at an average of $2,042.96 per ETH, according to details shared by the foundation. The organization confirmed the agreement in a post on X, explaining that the transaction had been completed with BitMine acting as the direct counterparty. Unlike trades conducted on public exchanges, OTC deals allow large transactions to occur privately without significantly affecting market prices. In the announcement, the Ethereum Foundation stated:
The foundation also clarified how the proceeds from the transaction will be used, noting that the funds are intended to support key activities across the Ethereum ecosystem.
According to the announcement, the on-chain transfer will originate from an Ethereum Foundation Safe multisignature wallet. Multisignature wallets require approval from multiple participants before transactions are executed, providing an extra layer of security and transparency for large treasury operations. The sale highlights the foundation’s approach to managing its crypto reserves while continuing to fund long-term development of the Ethereum network. Instead of selling assets directly on exchanges, OTC transactions allow the organization to convert portions of its holdings while minimizing sudden price volatility. BitMine Immersion Technologies, the buyer in this deal, is a publicly traded company listed on the NYSE American exchange under the ticker BMNR. The firm has increasingly positioned itself as a major corporate holder of Ether. Industry treasury trackers estimate that BitMine currently holds more than 4.5 million ETH, valued at approximately $9.3 billion at current market prices.
The company is chaired by Tom Lee, co-founder of Fundstrat, and has been steadily expanding its Ether reserves as part of a broader digital asset strategy.

A Growing Trend of Corporate Ether Treasuries
The latest transaction also highlights the growing interest among publicly traded companies in holding Ether as part of their corporate treasury strategies. BitMine has been accumulating ETH since mid-2025, adopting an approach that many observers compare to the strategy used by Strategy, formerly MicroStrategy, which famously built one of the world’s largest corporate Bitcoin holdings. Instead of focusing solely on Bitcoin, however, BitMine has concentrated on Ether, the native cryptocurrency of the Ethereum network. Ethereum powers a wide range of decentralized applications, including decentralized finance platforms, NFT marketplaces, and blockchain-based infrastructure projects. The company’s accumulation strategy has placed it among the largest institutional holders of Ether globally. For the Ethereum Foundation, the OTC sale marks the second time it has directly sold ETH to a corporate treasury buyer through a negotiated agreement.
A similar transaction occurred in July 2025, when the foundation sold 10,000 ETH to SharpLink Gaming. That deal was completed at an average price of $2,572.37 per ETH, giving the transaction a total value of around $25.7 million. Such deals reflect a growing connection between the Ethereum ecosystem and institutional investors. While Ethereum originally emerged as an open-source blockchain maintained by developers and volunteers, the network now supports billions of dollars in financial activity and has attracted significant corporate interest. For treasury buyers like BitMine, OTC purchases provide a direct method to accumulate large amounts of ETH without creating sudden swings in market price. These deals are typically negotiated privately between the buyer and seller before being executed on-chain.
Treasury Strategy and Ethereum’s Long-Term Development
The Ethereum Foundation’s recent sale is part of a broader treasury management strategy that the organization introduced in June 2025. Under this framework, the foundation periodically converts portions of its ETH reserves into fiat currency or other liquid resources to support ongoing operations. The policy aims to maintain a stable financial runway while ensuring the organization can continue funding research and development across the Ethereum ecosystem. According to the framework, the foundation targets annual spending equal to roughly 15% of its treasury holdings. This approach is designed to maintain a multi-year operating reserve while still supporting growth initiatives. Funds generated from these periodic sales help support several core areas of work, including protocol upgrades, security research, developer tools, and grant programs that assist teams building applications on Ethereum.
At the same time, the foundation has also been expanding its involvement in staking, the process used to help secure the Ethereum network. Earlier this year, the organization revealed plans to deploy approximately 70,000 ETH into validator nodes using open-source infrastructure. Validators help confirm transactions and maintain the network, earning rewards in return for participating in the process. By staking a portion of its treasury, the foundation aims to contribute to network security while generating sustainable returns that can support long-term operations. The OTC sale also comes shortly after the Ethereum Foundation released a new organizational mandate outlining its role in the broader ecosystem. In that document, the foundation emphasized that Ethereum should remain open source, censorship-resistant, and privacy-focused, while also scaling to support global adoption. The mandate also highlighted the organization’s intention to gradually reduce its direct influence over the network as the ecosystem matures.
Closing Thoughts
The foundation plans to focus on supporting core infrastructure such as protocol development, cybersecurity initiatives, and research that benefits the entire Ethereum community. This shift reflects the philosophy that Ethereum should ultimately operate as a decentralized network maintained by a wide range of contributors. As institutional interest in Ether continues to grow, similar treasury deals may become more common, linking the development of open blockchain infrastructure with corporate investment strategies.
