Did I miss something? Or am I losing my mind?
This week a headline popped up that smelled like déjà vu. Deep Fission announced it was going public. They want investor money to build underground reactors. Specifically to power AI data centers, the industry’s current golden goose.
Wait.
Didn’t I just cover this? I swear I did.
I dug up my old notes. Last September. Deep Fission went public then too. Not the flashy Nasdaq style, though. They did a reverse merger with a Delaware shell called Surfside. Private company meets empty public entity, boom, stock ticker. They raised $30 million in a side deal, selling shares at $3 each. Now? They’re chasing a Nasdaq IPO. Pricing shares between $24 and $26. Aiming for $157 million.
See the confusion? I thought so.
Here is the kicker: That first listing was public in spirit only.
Technically, Deep Fission became an SEC reporting company after the merger with Surfside. But its stock never actually moved on any market. The plan was to list on OTCQB. That’s the graveyard for companies too small or rough-edged for the big boys like NYSE. Yet if you search for Deep Fission on the OTC website right now, nothing happens. Not even a whisper. The company’s new S-1 filing confirms this denial. No trading ever happened.
Deep Fission told TechCrunch to stay away during their “quiet period” before the big launch. Classic move.
This time they are walking the traditional path. The numbers look ambitious. The new IPO values Deep Fission at up to $1.6 billion. Think about that for a second. Just twelve months ago they couldn’t scrape together $15 million.
The S-1 filed in May paints a uglier picture than the December draft. The timeline for the first reactor slipped. Hard. Back in winter they promised “criticality”—when the chain reaction sustains itself—by July 2026. The May file? Silent on that. No date given. Just silence.
They are drilling a test well, which is something, I suppose.
They have also lost a fortune.
The “going concern” warning is still there. Same text as before. In plain English: If this IPO fails, Deep Fission runs out of cash in 12 months or less.
Their financials have deteriorated since last fall. The deficit hit $88.1 million in March. Up from $56 million before that. Cash reserves shrank by 7% in just six weeks. Burn rate is high. Drilling costs money. Time costs money.
Technically, the focus has shifted to getting holes in the ground.
Maybe making holes isn’t as easy as they thought.
They started drilling one of three test wells last March. This specific well goes 6,000 feet down. It is eight inches wide. Tiny. For a nuclear reactor.
Commercial scale will require boreholes between 30 and 50 inches wide. And a mile deep. These dimensions dwarf standard oil and gas drills. Deep Fission admits it hasn’t locked down the final size. You cannot finalize your reactor design if you do not know how wide the hole is going to be. Chicken and egg, but with uranium and high pressure.
So why the big swing for $160 million now? What changed since December?
One factor: Blue Owl, a data center heavy hitter, threw $20 million into the pot. Part of a larger $80 million round. Blue Owl even signed a non-binding memo to buy power later. It is good PR. It does not erase the cash burn. The “going concern” warning remains.
It is hard to imagine the company is hiding some secret technical breakthrough while pleading with regulators. Unlikely.
More probable explanation?
Everyone is hot on fission right now. Investors see “nuclear” and “AI” and their brains short circuit in the best way possible. X-energy, another nuclear startup, had an upsized IPO last month. The market loves it.
But there is a difference between hype and reality. X-energy makes revenue. X-energy is farther along in the NRC licensing maze. Deep Fission has neither. Valuation tracks progress sometimes. Often, it does not.
Why is Deep Fission forcing this IPO? Progress seems to be lagging. Money seems to be vanishing. The timeline is a blur.
They are selling a vision. Just hope the drill doesn’t hit something harder than rock.
