Ether Machine has called off its planned public debut, announcing the immediate termination of its merger agreement with Nasdaq-listed special purpose acquisition company Dynamix Corporation, citing deteriorating market conditions. The Ethereum treasury-focused firm said the decision to end the transaction was mutual. The SPAC deal had been structured to take Ether Machine public with participation from The Ether Reserve LLC.
A filing with the U.S. Securities and Exchange Commission states that an unnamed “Payor,” identified in an annex to the agreement but not publicly disclosed, must pay $50 million to Dynamix within 15 days after the termination becomes effective.
Ether Machine had unveiled plans in July to launch what it described as the largest institutional, yield-bearing Ether (ETH) fund. Co-founded by former Consensys executives Andrew Keys and David Merin, the company intended to list on Nasdaq under the ticker ETHM and start with more than 400,000 ETH under management (valued at over $1.5 billion at the time of the announcement).
In September, Ether Machine raised $654 million in a private financing round that included 150,000 ETH contributed by Ethereum supporter Jeffrey Berns, who subsequently joined the company’s board. That fundraising formed part of a broader plan to build a large Ether treasury ahead of the Nasdaq listing, which will no longer proceed.
Dynamix retains a limited window to complete an alternative business combination: per its charter, the SPAC has until Nov. 22, 2026 to secure another deal. If it fails to do so, Dynamix would be required to liquidate and return trust funds to shareholders.
The cancellation comes amid broader strains in Ethereum treasury strategies. Trend Research has fully unwound its Ethereum holdings, selling 651,757 ETH—about $1.34 billion—and realizing an estimated $747 million loss. Separately, ETHZilla, which shifted from biotech to an Ethereum treasury approach during 2025’s market hype, has moved away from Ether accumulation and rebranded as Forum Markets.
