While it looks like OpenAI's IPO has been put on ice as they try to paint SpaceX as the scapegoat, there's still one sector that simply can't launch the IPOs and SPACs fast enough. 

After an announcement earlier this year that saw nuclear industrial company Holtec file privately for an IPO, one of the leading reactor developers X-energy debuted on the public market at an almost $10 billion valuation.

Since then, microreactor developer Hadron Energy has completed their SPAC merger and has subsequently been digging itself deeper into a hole every passing day…

There's now another reactor developer, NuCube, finding its way to the public market through a SPAC merger. This follows a similar announcement from European reactor developer newcleo that we detailed last month.

The company is joining a rapidly growing pool of startups looking to capitalize on the national energy security theme, with the added bonus of the AI revolution demanding a nuclear renaissance. Adding NuCube to the list, the number of public reactor development companies has now reached double digits:

• SMR - NuScale Power
• OKLO - Oklo Inc
• NNE - NANO Nuclear Energy 
• IMSR - Terrestrial Energy
• NKLR - Terra Innovatum
• HDRN - Hadron Energy
• XE - X-energy
• FISN - Deep Fission
• NHIC (NWCL) - Newcleo
• LPBB (tbd) - NuCube Energy

In the press release, the company highlights their current relationship with Halliburton as cause for differentiation from other reactor developers still working on their supply chain. Outside of recent acceptance for the Nuclear Energy Launch Pad program, the company doesn't appear to have any MOUs or LOIs lined up with potential off-takers. 

The reactor design is unique, but shares similarities with designs from Westinghouse and Antares. Their “solid-state microreactors” are not designed to utilize traditional coolants or pumps, but instead will rely on advanced heat wicking methods similar to what's used in electronics. 

With respect to historical precedence, this type of reactor design has some of the least operational experience in the nuclear industry's history. 

Some of the nuclear names have found themselves trading well above their entry price from going public, including Oklo and NANO Nuclear. But some of the other names have fared far more miserably…
