Nuclear stocks rally as Oklo and NuScale Power results lift reactor developers

what happened

Shares of nuclear energy companies rose sharply on Friday after quarterly reports from Oklo and NuScale Power, according to Seeking Alpha. Oklo shares gained about 23%, NuScale Power rose 16%, Centrus Energy climbed 17%, Vistra advanced 11%, X-Energy added 16% and Nano Nuclear Energy gained 15%.

Oklo posted a third-quarter net loss of $41.7 million, narrower than analysts expected, with revenue of $1.86 million. Vistra reported adjusted EBITDA of $2.38 billion, above the roughly $2.1 billion forecast, and executives said demand from data centers stayed strong in Texas and the PJM market.

The jump followed a difficult stretch after Democrats won control of Congress in the midterm elections. Investors had worried that tighter scrutiny of data centers could delay power projects, and electricity producers had fallen sharply before the rebound.

why it matters

For investors, the key distinction is between established generators such as Vistra, which already earn operating profits, and reactor developers that still need approvals, construction milestones and long-term contracts. Raymond James suggested investors may have overreacted to the election, but Oklo remains about 67% below its level at the start of 2026.
