Oklo catches a nuclear-rally tailwind

The rally wasn’t actually about Oklo

Oklo didn’t sign the deal, but it got to ride shotgun anyway. Alphabet’s Google just inked a 20-year agreement with Constellation Energy to add 890 megawatts of nuclear capacity to the PJM grid, and suddenly nuclear stocks were acting like they’d found the cheat code for the AI energy crunch.

Why the market cares

Here’s the basic plot twist: AI data centers are guzzling electricity, and utilities need serious, long-term power sources. Google’s commitment is the kind of multi-decade demand signal that tells the market nuclear isn’t just a nostalgia trade for people who still own old uranium charts.

The deal will help fund upgrades across 11 Constellation-owned reactors, with more than $4.3 billion in investment tied to it and the first increment expected by 2028. Google also signed a separate 15-year deal for 2,700 megawatts from Constellation’s PJM fleet. Translation: the AI power story keeps getting louder, not quieter.

Why Oklo gets a lift anyway

Oklo is building its own build-own-operate model, selling electricity directly to customers with its Aurora fast-fission reactors. It’s not in this Constellation pact, but the market is connecting the dots: if hyperscalers are signing 20-year nuclear contracts today, there may be a long runway for more deals tomorrow.

That matters because Oklo is aiming to start its first powerhouse at Idaho National Laboratory in 2028 and already has long-term arrangements with Switch and Meta. So even if this headline is about Google and Constellation, the broader message is: the nuclear power market just got another very expensive vote of confidence.

Big picture: sometimes the stock that moves most is the one not in the room — as long as it’s selling the same future.
