The Ether Machine, a major Ethereum treasury management firm, has filed a draft registration with the U.S. Securities and Exchange Commission (SEC) as it moves forward with plans to go public through a merger with Dynamix Corporation.
In a statement shared Tuesday on X, the company said it is “shifting into the next gear” as it prepares for full public status. The filing, submitted under Form S-4, is typically used to register securities tied to mergers, acquisitions, or similar business combinations.

Path to Nasdaq Listing
The filing relates to The Ether Machine’s proposed merger with Dynamix Corporation, a special-purpose acquisition company (SPAC) that trades on Nasdaq under the ticker ETHM. The Ether Machine first announced the plan in July, noting that it expects the deal to close in the fourth quarter of this year.
The merger remains subject to customary conditions, including approval from Dynamix shareholders at an upcoming extraordinary general meeting. If approved, the transaction would mark a key milestone in bringing one of Ethereum’s largest treasury holders to public markets.
Growing Ethereum Holdings
Alongside its public listing ambitions, The Ether Machine has continued to build its corporate treasury. Earlier this month, the firm disclosed it had added 150,000 ETH in August, lifting its total holdings to 495,362 ETH.
According to data from SER, this positions The Ether Machine as the third-largest corporate holder of Ethereum, behind Bitmine Immersion Tech and SharpLink Gaming.

Looking Ahead
With the SEC filing in progress and shareholder approval pending, The Ether Machine’s path to Nasdaq could make it one of the most prominent Ethereum-focused firms to go public in the U.S. Its growing ETH reserves underscore the company’s strategy of positioning itself as a leading player at the intersection of digital assets and traditional finance.
