The selloff in pre-revenue nuclear stocks is widening, with Oklo leading a 28% monthly decline that has erased nearly half the company's year-to-date value. Oklo Inc. shares fell 9.6% to $41.31 on Thursday, extending a month-long slide that has wiped 28% from the stock and 42% year to date, as investors rotate out of speculative nuclear developers. "The market is drawing a sharp line between pre-revenue reactor developers and profitable nuclear utilities," said Omar Tariq, energy analyst at Edgen. "Oklo and NuScale trade on milestones and sentiment, not earnings — and sentiment has shifted." NuScale Power Corp. has dropped 23% over the same period, while Uranium Energy Corp. fell 18% in the past month and another 5% Thursday to $9.56. The VanEck Uranium and Nuclear ETF, which counts Oklo as its second-largest holding at 6.37% behind Cameco Corp.'s 23.46% weighting, declined 16% for the month and 4.4% on the day to $39.10. The divergence tells the story: Constellation Energy Corp., which trades at 22 times earnings with $11.51 in EPS, fell just 2% over the past month. Vistra Corp. gained 5%. Oklo holds $275 million in cash but posted a $73.6 million net loss in fiscal 2024 and targets first commercial power no earlier than late 2027 — a timeline that leaves the stock exposed to sentiment swings with no revenue to anchor valuation. **Why Pre-Revenue Names Are Getting Hit Hardest** Oklo's slide has no single confirmed catalyst. The selloff reflects a broader de-rating of high-beta nuclear names as investors weigh missed milestone deadlines, regulatory uncertainty around NRC licensing, and insider selling — though those sales are frequently routine 10b5-1 plan transactions and not necessarily directional signals. The company's bull case rests on a 12-gigawatt agreement with Switch and a $25 million pre-payment from Equinix Inc., signaling data-center demand for nuclear-powered AI infrastructure. But with zero revenue and a consensus analyst price target of $86.95 — more than double the current $41 stock price — the gap between narrative and financial reality has widened. **Profitable Utilities Hold Their Ground** The contrast with Constellation and Vistra highlights the market's preference for cash flow over promises. Constellation reaffirmed 2026 adjusted EPS guidance of $11 to $12, while Vistra reaffirmed adjusted EBITDA guidance of $6.8 billion to $7.6 billion and was recently upgraded to investment grade by Fitch Ratings. For investors seeking nuclear exposure without single-stock risk, the VanEck Uranium and Nuclear ETF offers a diversified basket. But its 16% monthly decline shows that even broad-based funds are not immune to the sector's rotation. The nuclear trade is splitting into two distinct narratives. Profitable utilities with real earnings and hyperscaler power-purchase agreements are holding value. Pre-revenue developers like Oklo and NuScale remain high-conviction bets on a 2027-2028 payoff timeline — but with no earnings to absorb shocks, position sizing matters. The next catalyst for Oklo will be its NRC licensing update, which could either restore confidence or deepen the selloff.

**Oklo's Groves reactor became the first privately-owned advanced nuclear project to clear final safety review by the U.S. Department of Energy.** Oklo Inc. secured U.S. Department of Energy approval for the final safety analysis of its Groves Isotope Test Reactor in Texas, clearing the path for first criticality this month and marking a milestone for privately-developed advanced nuclear. "This is a truly representative facility of future commercial facilities that Oklo intends to build and operate," Jacob DeWitte, co-founder and chief executive officer of Oklo, said. The Documented Safety Analysis, the facility's final safety basis grounded in detailed technical analysis of potential hazards and safety controls, follows the preliminary DSA approved during design and construction. Groves now enters the DOE's final pre-startup review, including a readiness assessment and startup authorization. Once approved, the facility can receive and load nuclear fuel, conduct startup testing, and achieve first criticality — the point at which a reactor sustains a controlled, self-sustaining nuclear chain reaction. Oklo is targeting that milestone for July 2026, less than a year after breaking ground in Texas. Oklo shares rose 5.1% in pre-market trading Wednesday. The company has more than 15 gigawatts under contract, including a deal with Meta Platforms, and holds more than $2 billion in cash. Oklo plans full commercial operations by late 2027 or early 2028, with analysts projecting the stock could trade above $100 per share, roughly double its current level. **A Blueprint for Private-Sector Nuclear** The Groves project is the first advanced reactor to receive DSA approval on privately owned land using wholly commercially sourced fuel, equipment, and systems, according to Oklo. The facility operates under the DOE's Reactor Pilot Program, established after an executive order calling for multiple advanced reactors to go critical outside national laboratories. "Groves provides a blueprint for how the United States can accelerate advanced reactor deployment while maintaining a rigorous, practical safety process," DeWitte said. Oklo was the first company to receive a site use permit from the DOE for a commercial advanced fission plant and was awarded fuel from Idaho National Laboratory. It also submitted the first custom combined license application for an advanced reactor to the Nuclear Regulatory Commission, though that licensing process remains a key risk factor for its commercial fleet. The Groves reactor uses a fast fission design, which differs from conventional light-water reactors by using fast neutrons to sustain the chain reaction, enabling higher fuel efficiency and the potential to recycle used nuclear fuel. **Isotope Production and the Commercial Roadmap** Groves supports Oklo's isotope business, producing materials used in cancer diagnosis and treatment, advanced manufacturing, scientific research, space exploration, and national security. Many critical isotopes are currently sourced from overseas suppliers or aging domestic facilities, creating supply-chain risks for hospitals, industry, and government users. The pilot facility will validate production processes and operating procedures before Oklo scales to commercial operations, targeted for late 2027 or early 2028. The company is also developing advanced fuel recycling technologies in collaboration with the DOE and U.S. national laboratories. **Investment Angle** Oklo's progress on Groves strengthens its position in the nuclear energy market, where demand from AI data centers is driving interest in dispatchable clean power. The company's Aurora fast fission powerhouse is designed to deliver reliable electricity at commercial scale. With $2 billion in cash and more than 15 GW under contract, Oklo is well-capitalized relative to peers in the small modular reactor space, though NRC licensing for its commercial reactors remains a key uncertainty. Analysts see the stock potentially reaching $100 per share, implying roughly 100% upside from current levels, as the company moves from pilot to commercial deployment.

**Oklo's Aurora powerhouse — a 15-MW advanced fission reactor using HALEU fuel — could become one of the first commercial small modular reactors in the US, with a signed Meta Platforms deal and more than 15 GW of customer commitments already in hand.** Oklo Inc. and Meta Platforms entered a long-term clean energy agreement to develop nuclear powerhouses in Ohio, marking one of the largest corporate offtake deals for advanced nuclear technology. The partnership centers on Oklo's Aurora-Ohio project, a 1.2-GW power campus that will supply Meta's data centers with carbon-free baseload electricity. "This agreement validates our business model and demonstrates that advanced nuclear can meet the scale requirements of hyperscale data center operators," Jacob DeWitte, co-founder and chief executive officer of Oklo, said in a statement. "Meta's commitment gives us a clear demand signal for the Aurora platform." Oklo's Aurora powerhouse is a 15-MW fast reactor that uses HALEU — high-assay low-enriched uranium, enriched to 19.75%, compared with 3% to 5% for conventional reactors. The company plans to deploy multiple Aurora units at the Ohio site to reach the 1.2-GW total capacity. First commercial operation is targeted for late 2027 or early 2028. The company has secured more than 15 GW of customer commitments across data center, industrial, and government customers. It also signed a letter of intent with Centrus Energy Corp. for HALEU fuel supply covering up to five Aurora reactors starting in 2029, strengthening its fuel supply chain for the Ohio project. **Regulatory progress and financial runway** Oklo received Nuclear Regulatory Commission approval for its Principal Design Criteria topical report, a key step toward a full construction permit application. The company also acquired ARMEC, an engineering and manufacturing firm, to reduce supplier dependence and bring reactor component production in-house. Oklo holds more than $2 billion in cash, giving it a multi-year runway as it works through the NRC licensing process. The company's burn rate remains manageable relative to its cash position, according to its most recent filings. Shares have fallen 30.3% year to date, compared with a 17.3% decline at peer NANO Nuclear Energy Inc., which trades at 1.74 times book value versus Oklo's 3.3 times. **The competitive landscape** Oklo faces competition from NANO Nuclear, whose KRONOS MMR microreactor has entered formal NRC review for a construction permit tied to the University of Illinois Urbana-Champaign. NANO Nuclear reported $569 million in cash and has a partnership with Supermicro to explore AI data center power solutions. Its regulatory timeline could allow initial construction in the second half of 2027. Centrus Energy, the sole US-owned supplier of HALEU, also stands to benefit from Oklo's deployment timeline. The LOI with Oklo reinforces Centrus's position as the domestic fuel supplier for the advanced reactor ecosystem, though the agreement is not yet a definitive contract. **What's at stake for investors** Oklo's success hinges on NRC licensing timelines. Any delay in approval could allow competitors to close the gap and force Oklo to dilute shareholders to raise additional capital. But if the company delivers on its 2028 target, the Meta deal alone represents a multi-gigawatt revenue stream that few pre-revenue nuclear developers can match. Analysts' high-end estimates project Oklo trading above $100 per share within five years, roughly double its current price near $50. For risk-tolerant investors betting on AI's insatiable demand for dispatchable clean power, Oklo offers one of the most direct plays on the convergence of nuclear energy and data center infrastructure.

**Oklo's acquisition of Creative Engineers brings three decades of sodium-handling expertise in-house, accelerating the path to commercializing its sodium-cooled Aurora fast reactor.** Oklo Inc. acquired Creative Engineers Inc., a specialist in sodium and alkali-metal systems with about 20 engineers and fabricators, to internalize critical capabilities for its Aurora sodium-cooled fast reactor. The deal brings CEI's expertise in liquid-metal systems, component development, fabrication, and applied research and development into Oklo's expanding technical organization. "CEI brings specialized sodium- and alkali-metal engineering capabilities that are directly relevant to Oklo," co-founder and Chief Executive Officer Jacob DeWitte said. "They have already been a strong technical partner, and bringing that expertise in-house will help accelerate our path to commercialization." Founded in 1996, CEI has worked on landmark US sodium reactor programs including the Fast Flux Test Facility, Fermi 1, and Experimental Breeder Reactor II. The company has generated positive free cash flow for more than five years and manufactures pumps, flow meters, and pressure transmitters for liquid-metal systems. CEI President Rich VanLieshout said the team has "built its reputation around solving difficult engineering challenges involving sodium and other alkali metals." The acquisition strengthens Oklo's ability to handle sodium systems — a core requirement for its Aurora powerhouse, a sodium-cooled fast reactor that uses passive safety characteristics and natural circulation for decay heat removal. Oklo submitted the first custom combined license application for an advanced reactor to the US Nuclear Regulatory Commission and has a site use permit from the Department of Energy. Bringing CEI's expertise in-house reduces execution risk on specialized equipment, fabrication, and testing as the company moves toward deployment. CEI's capabilities extend beyond sodium to include sodium-potassium alloy and lithium systems, as well as applied research in reactive metals. The company also works with metallization of high-value materials including silicon, titanium, tantalum, hafnium, scandium, and rare earth elements. CEI will maintain its existing commercial relationships across the nuclear sector while supporting Oklo's programs. The Aurora design is a liquid-metal fast reactor that operates at atmospheric pressure and uses sodium as a coolant. Unlike conventional light-water reactors that require pressurized systems, sodium-cooled fast reactors can achieve higher fuel efficiency and produce less long-lived waste. The technology also supports Oklo's broader strategy of developing fuel recycling capabilities to convert used nuclear fuel into clean energy, a process the company is pursuing in collaboration with the Department of Energy and US National Laboratories. For investors, the deal reflects Oklo's commitment to building in-house technical capacity for its reactor design rather than relying solely on external contractors. Oklo, which went public via a SPAC merger in 2024, trades on the New York Stock Exchange under the ticker OKLO. The company has not disclosed the financial terms of the acquisition, though CEI's positive free cash flow profile means the deal adds a revenue-generating business while strengthening Oklo's specialized engineering capabilities.

Advanced nuclear developers Oklo Inc. and NANO Nuclear Energy are competing for a slice of the surging demand for carbon-free baseload power, as AI data centers, reshoring and grid reliability needs push electricity demand higher. The two early-stage companies offer investors different bets on how the nuclear renaissance will unfold — one built around a vertically integrated platform with customer-linked projects, the other around regulatory momentum and a stronger balance sheet. "Both companies are pre-revenue and carry execution risk, but the market is starting to differentiate based on timeline visibility and cash position," said Omar Tariq, energy transition analyst at Edgen. "NANO Nuclear has a clearer near-term regulatory path, while Oklo has the more ambitious platform story." Oklo is developing the Aurora powerhouse, a fission plant capable of producing 15 to 75 megawatts of electricity, and plans to own and operate its reactors rather than just sell the technology. The Santa Clara, California-based company, backed by Chairman Sam Altman and led by CEO Jacob DeWitte, has secured a partnership with Meta Platforms to build a 1.2-gigawatt nuclear campus in Pike County, Ohio, to supply clean energy for Meta's regional data centers, including its AI supercluster in New Albany. A separate collaboration with Nvidia at Los Alamos National Laboratory advances nuclear fuel validation for AI-powered data centers. Oklo reported a first-quarter 2026 net loss of $33.1 million, widening from $9.8 million a year earlier, with no revenue recognized. It ended the quarter with $2.5 billion in cash after a $1.2 billion at-the-market equity offering. NANO Nuclear is developing microreactors for data centers, remote communities and military applications. Its lead KRONOS MMR is a stationary high-temperature gas-cooled microreactor, while ZEUS and LOKI expand into portable and space-capable designs. The Nuclear Regulatory Commission has started formal review of the KRONOS construction permit application tied to the University of Illinois Urbana-Champaign, with environmental assessment work scheduled for spring 2027 and safety evaluation in early fall 2027, keeping open the possibility of initial construction in the second half of 2027. The company holds $569 million in cash and short-term investments, giving it a longer runway than many early-stage nuclear developers. NANO Nuclear reported a fiscal 2025 net loss of about $43.5 million, with no revenue. The two stocks have diverged in 2026 as investors have grown more selective after the nuclear trade ran hot last year. Oklo has fallen 30.3% year to date and trades 70% below its 52-week high of $193.84, reflecting a sharp de-rating as the market priced in persistent cash burn and a distant commercialization timeline. NANO Nuclear has declined 17.3% over the same period, holding up better on the strength of its cash position and visible regulatory milestones. On a price-to-book basis, Oklo trades at 3.3 times while NANO Nuclear trades at 1.74 times, giving NNE the cheaper valuation starting point. The key difference lies in fuel strategy and timeline. Oklo is building a vertically integrated fuel cycle, including the Aurora Fuel Fabrication Facility at Idaho National Laboratory, the Tennessee Advanced Fuel Center, and fuel recycling technology that converts used nuclear fuel into usable reactor fuel. A letter of intent with Centrus for high-assay low-enriched uranium (HALEU) supply for up to five Aurora reactors from 2029 adds credibility to the Ohio plan. HALEU, enriched to 19.75% compared with 3% to 5% for conventional reactor fuel, allows reactors to operate longer between refueling cycles but remains scarce, with limited domestic production capacity. NANO Nuclear is also building HALEU fuel fabrication capabilities and recently acquired Secured Transportation Services to strengthen its nuclear logistics chain. For investors, the choice comes down to platform breadth versus timeline visibility. Oklo's build-own-operate model and customer-linked projects — including the Meta campus and a partnership pipeline spanning data centers, industrial users and government customers — offer a larger addressable market but require years of capital, permitting and construction discipline before generating revenue. NANO Nuclear's focused microreactor strategy, stronger cash position and clearer regulatory milestones for KRONOS provide a more defined near-term catalyst, though its total addressable market is narrower. Neither company is expected to generate meaningful revenue before 2029, making funding, regulatory progress and project execution the critical factors to watch.

**The surge in AI data-center power demand is redirecting investor attention from SpaceX's blockbuster IPO to the nuclear energy stocks that could fuel the next phase of compute growth.** SpaceX's initial public offering, which sent shares up 6% on its first day of trading, has drawn fresh scrutiny to the company's prospectus claim that it has identified a $28.5 trillion total addressable market, more than 90% of which hinges on artificial intelligence. The catch, as SpaceX itself warned in its IPO filing, is that "energy supply is constrained globally due to the significant increase in demand for, and limited availability of, energy to power AI compute." That constraint is pushing investors toward small modular reactor developers Oklo and NuScale Power as potential beneficiaries of the AI infrastructure build-out. "The economics of SMRs are a bit complex," Bank of America analysts wrote in a recent report, noting that "when compared to traditional, large-scale NPPs, SMRs require less land, shorter construction periods, and have enhanced safety features." The bank said advancements in SMR technology "could likely reshape nuclear power supply chains over the next decade." Oklo, backed by OpenAI Chief Executive Officer Sam Altman, is targeting data center operators directly with its reactor designs, while NuScale is focused on grid-scale deployments through partnerships with electric utilities. Neither company has commercialized a single SMR system, though both maintain pipelines of prospective customers. The challenge is that SMR demonstration projects have faced cost overruns and delays, and renewable energy sources like solar and wind are becoming increasingly cost-competitive, potentially undercutting the economic case for small nuclear reactors. **Why AI needs nuclear power** The scale of the energy problem is difficult to overstate. AI data centers consume vastly more electricity than traditional computing facilities, and the pace of deployment is accelerating. Alphabet, Google's parent company, is already involved in the construction and rehabilitation of several nuclear energy sites, signaling that big tech sees atomic power as a viable solution for baseload generation without additional carbon emissions. Conventional nuclear power plants, however, take a decade or more to build — far too slow to keep pace with AI's energy demands. SMRs, typically defined as reactors under 300 megawatts electric that can be factory-built and assembled on site, offer a faster alternative. HALEU, or high-assay low-enriched uranium — enriched to 19.75 percent compared with 3 percent to 5 percent for conventional reactor fuel — is the fuel type most SMR designs require, adding another layer of supply chain complexity. **The investment case and its risks** Oklo shares rose 2.6 percent and NuScale gained 0.64 percent in recent trading as the SpaceX IPO narrative broadened into a wider conversation about AI infrastructure. Both stocks remain highly speculative. NuScale trades on the promise of utility-scale deployments that have yet to materialize, while Oklo's direct-to-data-center model depends on winning contracts from hyperscale operators that have historically preferred to build their own power solutions. For investors, the bull case rests on a simple premise: AI compute demand is growing faster than the grid can supply, and SMRs represent one of the few scalable, carbon-free baseload power sources that can be deployed on a timeline measured in years rather than decades. The bear case is equally straightforward — neither Oklo nor NuScale has proven its technology at commercial scale, and the cost trajectory of renewables continues to improve, narrowing the window for nuclear to compete on price. SpaceX's own long-term solution — orbital data centers powered by solar energy — remains years away from commercialization, if it ever arrives. In the meantime, the terrestrial energy demands of AI will need to be met by whatever technology can deliver, and SMR developers are positioning themselves as the answer. Whether the market agrees will depend on whether these companies can move from pipeline to production before the window of opportunity closes.

Oklo Inc. secured a fuel supply agreement with Centrus Energy Corp. to power up to five Aurora fast fission reactors at a planned 1.2-gigawatt campus in southern Ohio. Centrus will deliver high-assay low-enriched uranium from its Ohio facility starting in 2029. The deal addresses a critical bottleneck in the advanced nuclear sector: access to domestically sourced HALEU. Oklo Inc. secured a fuel supply agreement with Centrus Energy Corp. to power up to five Aurora fast fission reactors at a planned 1.2-gigawatt campus in southern Ohio, with deliveries of high-assay low-enriched uranium scheduled to begin in 2029. "This agreement aligns core elements of advanced nuclear deployment: power generation, fuel, and customer demand," Oklo co-founder and Chief Executive Officer Jacob DeWitte said. Centrus will supply HALEU from its American Centrifuge Plant in Pike County, Ohio, under a letter of intent that may include prepayments from Oklo to support the campus buildout. The deal follows Oklo's January 2026 agreement with Meta Platforms Inc., which also included prepayment provisions. Centrus plans to combine billions in private capital with a $900 million HALEU task order from the US Department of Energy. The agreement addresses one of the central constraints facing the advanced nuclear sector: access to domestically sourced HALEU, which is enriched to 19.75 percent compared with 3 percent to 5 percent for conventional reactor fuel. Oklo's Aurora powerhouses use liquid-metal cooling with low-water requirements and inherent safety characteristics, making them suited for industrial applications. The project is expected to require more than 700 full-time construction workers over multiple years, with each powerhouse supporting 40 to 50 permanent jobs. Centrus' expansion at Piketon is expected to create 1,000 construction jobs and 300 new operating positions in Ohio while retaining 150 existing roles. For every eight Aurora powerhouses deployed, an additional 80 to 120 permanent roles will support site-wide operations. Oklo was the first company to receive a site use permit from the DOE for a commercial advanced fission plant and submitted the first custom combined license application for an advanced reactor to the Nuclear Regulatory Commission. The company is also developing advanced fuel recycling technologies in collaboration with the DOE and US national laboratories. The deal strengthens fuel supply certainty for Oklo's Aurora deployments at a time when HALEU availability remains a bottleneck for the advanced nuclear industry. Kiewit Corp., one of North America's largest construction and engineering organizations, is providing engineering and construction experience for the project. Oklo shares, which trade on the New York Stock Exchange under the ticker OKLO, are likely to benefit from the reduced fuel supply risk. Centrus (NYSE: LEU) gains a marquee customer for its HALEU production capabilities, validating the commercial viability of its American Centrifuge Plant expansion. Oklo trades at a valuation that reflects the early-stage nature of its technology, and the fuel agreement removes one layer of execution uncertainty for investors tracking the advanced nuclear sector.
