Nuclear energy stocks exploded higher on Friday after Meta Platforms Inc. (META) dropped what might be the biggest validation the atomic energy sector has seen in decades. The social media giant announced deals totaling more than 6 gigawatts of nuclear capacity, and the message was clear: Big Tech isn't just dabbling in nuclear power anymore. They're going all in.

Meta's Double Nuclear Bet

The company's strategy came in two flavors. First, the safe play: a 20-year agreement with Vistra Corp. (VST) to purchase 2.6 gigawatts of energy from existing nuclear plants in Ohio and Pennsylvania. This is the kind of deal that makes CFOs happy because the infrastructure already exists and the power is reliable.

Then came the more adventurous move. Meta partnered with Sam Altman-backed Oklo Inc. (OKLO) to develop a 1.2-gigawatt advanced nuclear technology campus in Southern Ohio. This is next-generation stuff, the kind of bet that says Meta believes these emerging reactor designs will actually work at scale.

The market loved both angles. Oklo shares rocketed nearly 20% in early trading, while Vistra climbed over 10%. Investors are treating these deals as proof that advanced nuclear deployments aren't just science fiction anymore.

When One Giant Moves, Everyone Follows

The "Meta effect" didn't stay contained to the companies that signed deals. The entire nuclear supply chain caught fire. NuScale Power Corp. (SMR), which holds the distinction of being the only company with a certified small modular reactor design in the United States, jumped as traders anticipated more hyperscale agreements coming down the pipeline.

The uranium producers joined the party too. Cameco Corp. (CCJ) and Energy Fuels Inc. (UUUU) ripped higher as the long-term demand picture for nuclear fuel became impossible to ignore. NexGen Energy Ltd. (NXE) pushed toward all-time highs, with investors suddenly focused on whether new uranium production can come online fast enough to meet the 2030–2035 energy targets that Big Tech is now setting.

Even the smaller, higher-risk names caught a bid. Centrus Energy Corp. (LEU), Terrestrial Energy Inc. (ISMR), and Nano Nuclear Energy Inc. (NNE) all rose sharply. The catalyst here is the federal government's $2.7 billion HALEU funding program, which is expected to accelerate the commercialization of exactly the kind of advanced reactors Meta is now backing with real money.

Why This Actually Matters

Here's the underlying reality: AI models are getting more complex, and the electricity required to train them is outpacing what's readily available. Traditional power sources aren't cutting it, and renewable energy alone can't provide the always-on, carbon-free baseload power that data centers need. So Big Tech is turning to nuclear.

Meta isn't the first. Microsoft and Google have already secured nuclear power agreements. But Meta's announcement confirms this is a trend, not a one-off experiment. The nuclear sector is transitioning from a speculative play into a critical infrastructure component of the AI revolution.

When major tech companies start signing 20-year power agreements measured in gigawatts, that's not a publicity stunt. That's a fundamental shift in how they're planning to power the next decade of innovation. And the nuclear stocks are pricing that in, fast.
