The U.S. and U.K. will invest $350 billion in nuclear and other technologies.
The biggest beneficiary of the nuclear side of this deal appears to be privately owned X-Energy.
X-Energy is backed by Amazon.
Nano Nuclear Energy (NASDAQ: NNE), the tiny nuclear power company developing even tinier "micro" nuclear power plants, saw its stock soar 19.8% through 1:15 p.m. ET Friday.
The U.S. and U.K. governments agreed Thursday to cooperate in developing the two countries' artificial intelligence, quantum computing, and nuclear energy sectors, and to spend $350 billion doing so.

The British government says 150 billion pounds (US$195 billion) will be invested in the U.K., which it calls a "record-breaking investment," leaving $155 billion for the American AI, quantum, and nuclear sectors. But how much of this money goes to Nano Nuclear?
That's all they have to say on the subject of nuclear investments -- no mention of Nano Nuclear Energy stock at all.
Fact is, the biggest beneficiary here appears to be X-Energy (and its partner Centrica). If you recall, X-Energy is a private company backed by Amazon, partnering to build several gigawatts-worth of nuclear reactors for Amazon's data centers in the Pacific Northwest.
That's good to know if you want to keep an eye on X-Energy as a potential investment, should it ever go public. But it's terrible news for investors betting on Nano Nuclear stock to benefit from the $350 billion U.S.-U.K. deal.
Nano Nuclear stock therefore remains a sell for me.
