DEEP FISSION, INC. IPO - What You Need to Know

Thinking about jumping into the Deep Fission IPO? It is an exciting space. Before you invest your hard-earned money, let’s break down what this company does in plain English.

1. What does this company actually do?

Traditional nuclear power plants are massive, expensive, and complex projects that take years to build. Deep Fission wants to change that with their "Gravity Reactor." Instead of building a giant facility above ground, they plan to place small nuclear reactors about a mile underground in deep boreholes.

They use the earth’s natural pressure to help run the reactor and water in the borehole to keep it cool. Because these reactors are modular, they can be grouped into "clusters" to create larger power plants as energy needs grow. Their primary target is the massive, consistent energy appetite of AI data centers. These centers require reliable, carbon-free power that wind or solar cannot provide.

2. How do they make money and are they growing?

Deep Fission is currently a pre-revenue company in the research phase. They have not yet earned any money from electricity sales. Their business model aims to generate profit through three streams:

• Ownership: Keeping a stake in individual borehole projects to share in long-term electricity sales.
• Upfront Fees: Charging developers for initial engineering, site design, and reactor setup.
• Recurring Revenue: Collecting fees for technology licensing, maintenance, and fuel management.

They are building a network of industrial partners to reduce risk. They secured a $20 million investment from Blue Owl, a major player in digital infrastructure. They also signed agreements with Halliburton for drilling expertise and Urenco for nuclear fuel. These partnerships are essential for moving from design to deployment.

3. What will they do with the money from this IPO?

Deep Fission is offering 2,500,000 shares. They will use the money to move from the drawing board to commercial success:

• Engineering: Funding the validation of reactor designs and building full-scale prototypes at their Kansas facility.
• Regulatory: Financing the intensive, multi-year application process with the Department of Energy (DOE) and the Nuclear Regulatory Commission (NRC). They aim to secure a license for a pilot reactor by 2027.
• Deployment: Investing in surface-level infrastructure to convert heat from the underground reactors into electricity for the grid.

4. What are the main risks I should worry about?

• Technological Uncertainty: The Gravity Reactor is still in early engineering. The company has not yet proven that the technology works safely or efficiently at scale.
• Regulatory Hurdles: The nuclear industry faces strict safety and environmental oversight. If the NRC denies or delays the pilot reactor license, the company’s path to making money will be blocked.
• Internal Control Issues: The company found "material weaknesses" in its financial reporting as of March 2026. This means their accounting systems are not yet strong, which could lead to errors in their financial reports.
• Non-Binding Agreements: Many strategic relationships, including those with partners like Endeavour Energy, are non-binding. These partners are not legally required to commit money or buy the technology. These deals may never result in actual revenue.

5. The IPO Details

• Where will it trade? Nasdaq Global Market under the symbol "FISN".
• What is the price? Estimated between $16.00 and $18.00 per share.

A quick word of advice: Investing in a pre-revenue tech company is high-risk. You are betting on future technology that hasn't been fully tested. Before you buy, ask yourself if you are comfortable with the possibility that this technology may take years to reach the market—or may not reach it at all. Only invest money you are comfortable losing, and make sure you do your own research!
