Nuclear Startup Deep Fission Goes Public via Reverse Merger, Raises $30M for Underground Reactor Vision

In a move that marks a significant step forward for next-generation nuclear energy, Deep Fission, a startup developing compact underground nuclear reactors, announced Monday that it has gone public through a reverse merger, securing $30 million in fresh capital.

Deep Fission has taken an unconventional path to the public markets, merging with Surfside Acquisition Inc., a four-year-old special purpose acquisition company (SPAC). While many SPAC deals in the past have been priced at $10 per share, this offering came in at a notably lower $3 per share, signaling a shift in market expectations and valuation strategies for early-stage deep-tech startups.

A Bold Vision for Underground Nuclear Power

Deep Fission aims to revolutionize the nuclear industry by building small, cylindrical reactors that can be lowered into 30-inch-wide boreholes drilled one mile beneath the Earth’s surface. This underground deployment strategy is not just a novel engineering feat—it’s a direct response to longstanding safety, security, and regulatory concerns.

By burying reactors deep underground, the company hopes to mitigate the risk of meltdowns, protect installations from terrorist attacks, and reduce the need for large above-ground containment structures. These advancements could significantly lower the cost, permitting friction, and public resistance historically associated with nuclear energy.

The reactors, designed to produce 15 megawatts of power each, use pressurized water-cooling systems—a well-understood and proven technology already in use in nuclear submarines and many terrestrial power plants.

Momentum Building: Partnerships and Government Backing

Earlier this year, Deep Fission made headlines with a major partnership deal: a commitment with data center developer Endeavor to deploy 2 gigawatts of underground nuclear capacity. The deal reflects growing demand for low-carbon, high-density, and reliable power sources for energy-intensive industries like cloud computing and AI.

As recently as April, the company had been pursuing a $15 million seed round, highlighting how quickly its trajectory has shifted. By August, Deep Fission was selected as one of 10 advanced fission startups to participate in the U.S. Department of Energy’s Reactor Pilot Program—a streamlined regulatory pathway designed to accelerate the demonstration and deployment of new reactor technologies.

Trading Plans and Future Outlook

Following the reverse merger, the new public entity will retain the Deep Fission name. While its shares are not yet actively trading, the company has stated its intention to list on the OTCQB, an over-the-counter market aimed at emerging growth companies.

This development marks a rare public market debut in the nuclear space and underscores the broader momentum building around advanced nuclear technologies as governments, tech companies, and industrial players seek scalable clean energy solutions.
