Oklo<\/strong> (NYSE: OKLO)<\/span> and Nano Nuclear Energy<\/strong> (NASDAQ: NNE)<\/span> are both pre-revenue nuclear start-ups chasing the same multitrillion-dollar opportunity: small nuclear reactors that could one day provide clean, always-on power to artificial intelligence (AI) data centers and other power-hungry customers.<\/p>\n

Between the two, Oklo has the edge on partnerships, while Nano’s valuation looks more reasonable. Let’s take a closer at both to see which one is the better nuclear energy stock<\/a> today.<\/p>\n

Oklo: A rich valuation with big-name backers <\/h2>\n

Oklo<\/a> is designing a small nuclear reactor called an Aurora powerhouse. These reactors are engineered to run on both recycled fuel and high-assay low-enriched uranium (HALEU), a one-two punch that could make them more efficient, more flexible, and less dependent on the traditional nuclear fuel supply chain.<\/p>\n

Oklo’s strength is its partnerships. Never mind early backing by OpenAI CEO Sam Altman, Oklo now has major partnerships with Meta Platforms<\/strong>, Switch, Equinix<\/strong>, Nvidia<\/strong>, Vertiv<\/strong>, Liberty Energy<\/strong>, Blykalla, and RPower.<\/p>\n

The biggest opportunities for future revenue growth are the first three — Meta, Switch, and Equinix — which together equal about 14 gigawatts (GW) of potential power demand, or enough to require about 187 full-sized 75 megawatt (MW) Aurora powerhouses, if Oklo were to supply it all.<\/p>\n

If we assume about $40 to $90 per megawatt-hour, Oklo’s stated target price range, a full-sized 75 MW powerhouse could generate about $26 million to $59 million in annual revenue. At that rate, its 14 GW backlog clocks in around $4.9 billion to $11 billion — still below its $12.5 billion market cap.<\/p>\n

With a price-to-book ratio around 8 and zero revenue to its name, Oklo already commands a premium valuation. It’s not cheap, but the size of its potential demand explains why investors are still willing to pay up.<\/p>\n

Nano: An earlier play in a burgeoning industry <\/h2>\n

Nano Nuclear Energy is also designing small nuclear reactors. Like Oklo, the company is pre-revenue and lacks the regulatory approval to operate commercially.<\/p>\n

Nano doesn’t have as many star-studded partners as Oklo, but it does have a fairly big one: Super Micro Computer<\/strong> (NASDAQ: SMCI)<\/span>. Earlier in May 2026, the two companies signed a memorandum of understanding to deploy Nano’s microreactors for Super Micro Computers’ data centers.<\/p>\n<\/p><\/div>\n
