The Short Version
On Friday, shares of companies building new kinds of nuclear power plants jumped as much as 23% in a single day. The spark was Oklo, a company that hopes to switch on its first reactor in 2028 or 2029 and took in less than $2 million in its latest three months.
The surprise: a uranium fuel seller with $5.4 billion in orders on its books, some of them conditional, rose about as much as companies with almost no sales. Investors are treating very different businesses as one big bet on nuclear power for artificial intelligence data centers, the giant computer warehouses behind chatbots.
Seeking Alpha reported that nuclear energy stocks surged on Friday, November 6, after third-quarter results from Oklo and NuScale Power. Oklo rose about 23%, Centrus Energy 17%, NuScale 16%, X-Energy 16%, Nano Nuclear Energy 15% and Vistra 11%. The rally followed a selloff earlier in the week after the midterm elections gave Democrats control of Congress. Vistra fell about 14% on Wednesday. The report said bargain hunting and a reversal of bearish positioning contributed to Friday’s gains.
Oklo, whose quarterly report was filed with the SEC on November 6, posted a net loss of $41.7 million, narrower than analysts expected, on revenue of $1.86 million, and ended September with about $3.13 billion in cash. NuScale’s results release, filed November 5, reported $1.9 billion in cash and investments and a fabrication agreement with Doosan Enerbility. Centrus, which reported results on November 4, disclosed a $5.4 billion backlog that includes contingent orders.
Executive Summary
Two quarterly reports from pre-commercial reactor developers set off a broad move across the nuclear sector. The rally lifted companies with no operating reactors, a nuclear-fuel supplier and an established power producer by similar double-digit percentages. Oklo reported a narrower-than-expected loss and construction progress on its Aurora project in Idaho. NuScale reported a smaller-than-expected loss of 11 cents per share and said it had moved from design into physical production of its first commercial reactor module.
The more telling detail is how little the size of each move tracked the size of each business. Vistra generated $2.38 billion in adjusted operating earnings in the quarter. NuScale’s revenue was $281,000. Yet their stocks moved within a few percentage points of each other, and two companies with no news of their own, X-Energy and Nano Nuclear, kept pace. For anyone financing, contracting with or investing in nuclear supply for AI data centers, the market is still pricing this sector largely on one shared variable, AI-driven electricity demand and the policy outlook around it, rather than on company-by-company progress.
Different Businesses, One Price Move
Line up Friday’s gainers against their latest numbers and the spread is striking. Oklo, which has no operating reactor, booked $1.86 million of quarterly revenue and rose about 23%. NuScale, whose revenue fell to $281,000, gained 16%. Centrus, with $55.5 million of quarterly revenue and a $5.4 billion order backlog, rose 17%. Vistra reported $2.38 billion in adjusted EBITDA, which stands for earnings before interest, taxes, depreciation and amortization and is a common gauge of operating cash generation. It rose 11%. X-Energy and Nano Nuclear gained 16% and 15% with no comparable company-specific catalyst.
The mechanism is a shared narrative. Investors value all of these companies partly on the same question: how much reliable, around-the-clock power AI data centers will need, and whether policy will help or hinder supplying it. When that outlook shifts, every name reprices at once. The same thing happened in reverse two days earlier. After the midterm results raised concerns about energy policy and closer regulatory scrutiny of data centers, Vistra fell about 14% and other power producers dropped sharply. That makes two sector-wide moves in three trading days, each in the opposite direction. One week is not a long-run pattern, but it shows how tightly these stocks are currently coupled.
This coupling matters to more than traders. A utility or hyperscaler (the largest cloud operators, such as Meta) evaluating a nuclear supply partner cannot read much about a developer’s progress from its share price this week. A fuel supplier’s valuation is being pulled by sentiment toward reactors that are years from operation, even though it also serves the existing fleet.
For Reactor Developers, the Share Price Is the Financing Plan
The coupling bites hardest on developers that fund construction with equity. Oklo’s roughly $3.13 billion cash position is substantial against a $41.7 million quarterly loss. Its 10-Q includes at-the-market offering entries in its 2026 equity statements. An at-the-market offering is a program in which a company sells new shares gradually into the market at prevailing prices. With quarterly revenue under $2 million, equity is the engine of Oklo’s build. Even after Friday’s jump, the stock remains about 67% below where it started 2026, so any new share sales now dilute existing holders more for each dollar raised than they would have in January.
The practical consequence is that a sector-wide swing, whether an election selloff or a relief rally, changes a developer’s cost of capital without any change in its project. NuScale shows a related dynamic. Its results release reports $1.9 billion in cash and investments, and investment income rose $13.4 million year over year. That increase alone is about 48 times the company’s quarterly revenue, which illustrates how far these businesses still are from earning money by selling reactors or power.
Centrus Rides Two Fleets: Today’s Reactors and Tomorrow’s
Centrus sits upstream of the reactor developers. It supplies nuclear fuel and is expanding domestic uranium-enrichment capacity. Its 10-Q reports revenue in separate categories for separative work units (SWU) and uranium sales. A SWU measures the industrial effort needed to enrich uranium, which means raising the share of the fissile isotope that reactors burn. Demand for that work comes from both the operating reactor fleet and any new reactors that get built. Many advanced reactor developers plan around fuel enriched beyond today’s typical levels, so part of Centrus’s longer-term story depends on the same developers whose stocks it rallied alongside.
Centrus’s 17% gain was not purely sympathy with Oklo. Roth Capital upgraded the stock to Buy with a $115 price target, and the company recently reported progress manufacturing the centrifuges used to enrich uranium. Its quarterly figures point in two directions. Revenue fell to $55.5 million from $74.9 million a year earlier, and reported net income rose to $31.6 million, yet the company recorded an adjusted net loss of $9.4 million. The $5.4 billion backlog, which spans low-enriched uranium and higher-enrichment fuel contracts, includes contingent orders. That makes it a measure of potential demand rather than fully committed revenue.
What Actually Advanced This Quarter
Beneath the price moves, there was operational progress. Oklo said structural construction has begun on Aurora in Idaho and that the Department of Energy approved a preliminary safety analysis, an early review of the plant’s safety design. It is targeting initial operations in 2028 to 2029. NuScale signed an agreement with Doosan Enerbility to fabricate the upper reactor coolant system, which it calls the most complex component of its power module. It also reported fabricating first-of-a-kind safety components with MillenniTEK and deploying nuclear-specific AI tools developed with Nuclearn and NPX. NuScale says its design is the only small modular reactor certified by the Nuclear Regulatory Commission.
These are real steps, but they are steps toward capacity, not capacity. For data center operators, the nearer-term nuclear supply story remains with existing generators. Vistra executives said demand from data centers and other large customers remained strong in Texas and in PJM, the grid operator and wholesale market serving much of the mid-Atlantic and Midwest, and expressed confidence in securing more nuclear supply agreements. Raymond James analysts suggested the post-election selloff was an overreaction given the long-term outlook for electricity consumption. Friday’s gains combined earnings-driven buying with a rebound. They do not resolve the regulatory, cost and financing questions that will decide which developers deliver power.
Background
Nuclear power has drawn renewed investor attention as technology companies look for reliable, around-the-clock electricity for energy-intensive AI data centers. The publicly traded sector now spans several distinct business models. Established generators such as Vistra already run plants and earn operating profits. Advanced reactor developers such as Oklo, NuScale, X-Energy and Nano Nuclear are still designing, licensing and beginning to build. Fuel-cycle suppliers such as Centrus Energy provide the enriched uranium reactors burn.
NuScale, founded in 2007, says its power module is the only small modular reactor design certified by the US Nuclear Regulatory Commission. Oklo is building its first project, Aurora, in Idaho, and has a planned Ohio development associated with Meta. Centrus is expanding domestic enrichment capacity and manufacturing the centrifuges used to enrich uranium. X-Energy is developing high-temperature gas-cooled reactors.
