Nuclear startup company Oklo, backed by OpenAI's Sam Altman, is surging pre-market, up over 10% as investors get their first taste of what will likely be the primary source of power for AI in the decades to come. 

Nuclear names like Cameco are also popping on the news before the cash open Friday morning.

This momentum continues our "Next AI Trade" that we pointed out in April of this year, where we outlined various investment opportunities for powering up America, playing out.

The restart of Three Mile Island, specifically to sell energy to Microsoft to power its data centers, will be the most material advancement in the nuclear/AI thesis since we first outlined it.

Constellation Energy Corp. plans to restart the Three Mile Island reactor by 2028, according to a Friday statement. The reactor, closed in 2019 due to economic challenges, will reopen despite the site's other unit being shut down nearly 50 years ago after a major nuclear accident, according to Bloomberg.

The Bloomberg report noted that Microsoft has committed to a 20-year energy purchase from a nuclear facility, its first dedicated 100% nuclear energy deal. Financial details were not disclosed.

Constellation Chief Executive Officer Joe Dominguez said: "Policymakers and the market have received a huge wake-up call. There's no version of the future of this country that doesn't rely on these nuclear assets."

Constellation began exploring a restart of the reactor in early 2023 and decided to move forward, attracting Microsoft's interest, the report says.
