One of the biggest races in the nuclear power industry is to commercialize small modular reactors--which, at a fraction of the size of a traditional nuclear plant, can still produce about a third of the power of a standard reactor. The hype around this next generation of nuclear power hinges on the promise of providing AI data centers with all the energy they could possibly need. And with a market cap currently over $4 billion, at time of publishing, Oklo is one the hyperscalers are watching closely. Founded by couple Caroline and Jacob DeWitte in 2013, the company began construction last year on its Aurora "powerhouse" fast-fission power plant in Idaho and hopes to have it operational by 2028. Oklo, which was backed by Sam Altman before he launched OpenAI and has close ties to Energy Secretary Chris Wright, has benefitted from the Trump Administration's push to accelerate nuclear power development.
