# What Exactly Happened at Fermi?

According to TechCrunch, Fermi's CEO and CFO both left the company on April 20, 2026, with no named successors announced. The report, authored by Kirsten Korosec, noted that the startup has "faced headwinds" with its AI campus in Texas, though it did not specify whether the departures were voluntary or board-driven. The timing is striking: Fermi had been positioning itself as a key player in the AI-nuclear boom, leveraging Rick Perry's political network to secure permits and partnerships.

Reuters separately reported that Fermi's board has formed a search committee, but insiders suggest the dual exit reflects deeper disagreements over project timelines and funding. Neither the CEO nor the CFO issued public statements, and Fermi's press office declined to comment beyond confirming the departures.

My take: This is not a routine leadership change. Losing both the top executive and the financial gatekeeper simultaneously is a classic sign of a distressed startup, where investors have lost confidence and key personnel see no path to success. The lack of a clear succession plan makes Fermi's near-term viability doubtful.

# Why Did the Departures Happen Now?

According to Reuters, Fermi had been struggling to secure the final tranche of its Series C funding, which was contingent on hitting regulatory milestones for its Texas campus. The company had reportedly missed two deadlines for submitting safety analyses to the Nuclear Regulatory Commission (NRC), and local community opposition had delayed site preparation.

The Texas campus was supposed to pair a small modular reactor (SMR) with an AI data center, a model that has attracted billions in investment across the sector. However, Fermi's technology partner, a lesser-known SMR designer, had failed to deliver its reactor design on schedule, forcing Fermi to revise its power purchase agreements with potential AI tenants.

This timeline suggests the CEO and CFO were unable to bridge the gap between Fermi's ambitious promises and its actual progress. When a startup's leadership can't deliver on milestones, the board typically loses patience—and the executives, facing burnout and reputational risk, often jump ship.

# What Does This Mean for the Texas AI Campus?

The Texas AI campus, Fermi's flagship project, now faces an uncertain future. According to TechCrunch, the project was already "facing headwinds," including regulatory delays and community lawsuits. With the CEO and CFO gone, the company lacks the leadership to navigate these challenges.

Fermi had planned to break ground in late 2026, but that timeline is now in jeopardy. The company will need to find a new CEO who can restore investor confidence and a CFO who can manage the financial restructuring that likely awaits. Even if replacements are found quickly, the project will lose at least six to nine months of momentum, according to industry analysts cited by Reuters.

The broader implication is that AI-nuclear projects are not just about having a famous name attached. They require deep technical and regulatory expertise. Fermi's political pedigree—Rick Perry's involvement—was a differentiator, but it cannot overcome engineering and financial realities.

# Who Benefits From Fermi's Turmoil?

Fermi's loss is likely to be its competitors' gain. Oklo, backed by Sam Altman, and Kairos Power, which has a contract with Google, are both further along in their NRC licensing processes. According to a recent industry report cited by Reuters, Oklo expects to submit its construction permit application by mid-2026, while Kairos has already received a permit for its Hermes test reactor.

These competitors can now pitch to the same AI hyperscalers that Fermi was courting, arguing that they have more credible timelines and proven leadership. Microsoft, Amazon, and Google are all hungry for nuclear power to meet their AI data center energy demands, and they will likely favor startups that can demonstrate progress rather than promise.

Here's a comparison of the three key players:

# What Are the Broader Risks for AI-Nuclear Startups?

The Fermi debacle highlights a systemic risk: many AI-nuclear startups are overpromising on timelines and underdelivering on engineering. According to a report from the Breakthrough Institute, the average SMR project takes 10-15 years from concept to operation, yet many startups claim they can do it in 5-7 years. Fermi's failure to meet NRC milestones is a case study in this mismatch.

Investors are beginning to notice. The same Reuters report noted that venture capital into nuclear startups fell 20% in Q1 2026 compared to Q4 2025, as firms become more cautious about the sector's execution risks. This could create a funding crunch for weaker players, forcing consolidation.

For the AI industry, this is a warning: nuclear power is not a quick fix for data center energy needs. Hyperscalers need to diversify their energy sources and not rely solely on startups that may not deliver.

# What Should Investors and AI Companies Watch Next?

Investors should monitor Fermi's next moves: whether it can appoint a credible CEO within 60 days, and whether it can secure bridge financing. According to TechCrunch, Fermi has not announced any interim leadership, which is a red flag.

AI companies like Microsoft and Amazon should take note: they need to demand more rigorous due diligence when partnering with nuclear startups. A startup's board composition and the CEO's track record in regulated industries matter more than a famous co-founder.

Finally, regulators like the NRC should see Fermi's failure as a validation of their cautious approach. The agency's slow but thorough review process is designed to prevent exactly this kind of collapse, and it should not be rushed to accommodate AI's energy demands.

# What Are the Predictions for Fermi and the Sector?

1. Fermi will announce a merger or acquisition by Q2 2027, likely with a larger energy company that can absorb its assets and licenses.
2. Kairos Power will secure at least two additional AI data center partnerships by the end of 2026, cementing its leadership.
3. The NRC will cite Fermi's failure in its upcoming rulemaking on SMR licensing, effectively slowing down approval timelines for other startups.
