Nuclear Stocks Crash, With A Potential Payoff Still Years Away

  • Uranium prices have surged amid a structural supply deficit and a global policy-driven nuclear revival, but the sector faces long project timelines and mounting volatility.

  • Despite major investment pledges like the U.S.–Canada $80 billion reactor partnership, nuclear and uranium stocks have plunged 15–45% in recent weeks.

  • Investors confront the industry’s slow path to revenue.

Over the past couple of years, uranium and nuclear energy markets have enjoyed a renaissance thanks to surging global power demand and the global energy crisis triggered by Russia’s war in Ukraine. Uranium is no longer trading on legacy sentiment, with prices moving more on fundamentals characterized by tight physical supply, underbuilt production pipelines, and a policy-driven nuclear revival that’s accelerating faster than commodity markets anticipated.

The uranium market is experiencing a structural supply deficit, creating potential challenges for nuclear operators. 

Unlike many commodities, uranium trading usually involves small volumes with specialized participants, making the nuclear fuel susceptible to significant uranium market volatility. Meanwhile, governments across the globe are repositioning nuclear as critical infrastructure rather than transitional tech. Last month, the Trump administration struck a partnership with Canada’s Cameco Corp. (NYSE:CCJ) and Brookfield Asset Management (NYSE:BAM) to build at least $80 billion in nuclear reactors.

However, the harsh reality of the long lead and construction times of nuclear facilities, coupled with the fact that some stocks in the space with zero revenues are in nosebleed territory, has sent the sector into a tailspin. Nuclear and uranium stocks have pulled back sharply from recent highs, with many seeing double-digit losses: the sector's popular benchmark, VanEck Uranium and Nuclear ETF (NYSEARCA:NLR) has declined -16.6% over the past 30 days, at a time when the S&P 500 has gained nearly 3%.

Meanwhile, shares of advanced fission power plant developer, Oklo Inc. (NYSE:OKLO), are down -42.0% over the past month; Centrus Energy (NYSE:LEU) -35.9%, Energy Fuels Inc. (NYSE:UUUU) -33.9%, NuScale Power Corp. (NYSE:SMR) -47.7%, Uranium Energy Corp. (NYSE:UEC) -22.9%, BWX Technologies (NYSE:BWXT) -9.6%, Cameco Corp. (NYSE:CCJ) -6.1%, Vistra Corp. (NYSE:VST) -14.2% and NANO Nuclear Energy (NASDAQ:NNE) -40.2% and NexGen Energy (NYSE:NXE) -7.9%.

The market appears to be waking up to the reality that it could be up to a decade before we start to reap the benefits from the billions of dollars flowing into the sector. Whereas $80 billion can build enough reactors to power Virginia’s Data Center Alley, traditional reactors typically take 10 years or more to build. Meanwhile, the frequently touted small, modular reactors (SMRs) by the likes of NuScale Power, TerraPower and X-energy are still far from going mainstream primarily because the technology is still in early development and faces significant economic and regulatory hurdles. 

While some prototype units are operational in countries like Russia and China, most designs are still in the theoretical or early construction phases. Indeed, NuScale is the first and only U.S. company to have its SMR design certified by the U.S. Nuclear Regulatory Commission. NuScale's SMR features include a factory-fabricated, modular design that is scalable from one to 12 modules, with each module producing 77 MWe of power. Key features are its passive safety systems relying on gravity and convection, flexibility for on-grid and off-grid use, redundancy through independent modules, and a smaller footprint than traditional plants. 

Amazon, on the other hand, has invested in X-energy with the goal of deploying up to 5 GW of SMRs by 2039.

Only Oklo Inc., Kairos Power and TerraPower have begun construction of their SMR plants; however, none have proven they can produce power at a commercial scale nor received regulatory approval to build a commercial system.

There’s a lot going on, and nothing is going on,” BloombergNEF’s head nuclear analyst Chris Gadomski recently quipped.

To exacerbate matters, the markets have bid up these companies to absurd valuations despite many having no revenues to show for their troubles. To wit, Oklo’s market cap has at times exceeded $20 billion, despite the company having no operating reactors, no licenses to operate commercially, and no binding contracts to supply power. Wall Street analysts currently project Oklo will not generate significant revenue until late 2027 or 2028. Oklo’s current market cap is $15.3 billion.

Similar to Oklo, NANO Nuclear Energy currently sports a market cap of $1.6 billion with no revenue, no commercial products, and no commercial operation timeline. Its valuation is purely based on investor optimism about the future potential of nuclear energy, particularly in powering artificial intelligence data centers.

That said, the nuclear sector could see a quicker turnaround from restarting abandoned nuclear plants. Holtec International has laid out plans for its Palisades plant in Michigan to resume service early 2026 while Constellation Energy Corp. (NYSE:CEG) is on track to switch on its Three Mile Island reactor in 2027. Further, NextEra Energy Inc. (NYSE:NEE) recently announced that its Duane Arnold plant in Iowa will come back online by 2029.

Iran Minister Claims Nuclear Enrichment Halted After U.S.-Israeli Attack

  • Iranian Foreign Minister Abbas Araghchi claimed that Iran has been unable to enrich uranium since the US-Israeli attacks in June because their nuclear facilities were damaged.

  • Araghchi asserted that all facilities are under IAEA monitoring and that there is no undeclared enrichment, yet he defended Iran's "inalienable" right to pursue peaceful nuclear technology including enrichment.

  • The article suggests Iran's admission could be a bluff, as the country now has an incentive to secretly develop nuclear weapons while publicly claiming no enrichment is happening.

Iran, having seen its key nuclear facilities blown up by the Israeli and US surprise attacks of last June, and having long been under Washington and Western-led sanctions, could now be signaling a major olive branch. It is telling the West that there is nothing to worry about in terms of allegations of uranium enrichment or that it is striving toward a nuclear weapon.

Iranian Foreign Minister Abbas Araghchi said Sunday that the Islamic Republic has been unable to enrich uranium since the 12-day US-Israeli war.

In a very blunt and direct answer given to an Associated Press journalist visiting Iran, Araghchi stated "There is no undeclared nuclear enrichment in Iran." He described that "All of our facilities are under the safeguards and monitoring" of the International Atomic Energy Agency (IAEA), Araghchi said.

"There is no enrichment right now because our facilities - our enrichment facilities - have been attacked," he asserted.

Still, he defended Iran's right to enrich uranium as a matter of national sovereignty, saying "Iran’s right for enrichment, for peaceful use of nuclear technology, including enrichment, is undeniable."

"We have this right, and we continue to exercise that, and we hope that the international community, including the United States, recognize our rights and understand that this is an inalienable right of Iran. And we would never give up our rights," he added.

This has remained a consistent and standard argument from Iranian leaders - that it is not seeking a nuke, and that all its efforts are for peaceful nuclear energy needs. Various Ayatollahs over the years have even called nuclear weapons 'unIslamic'.

Throughout its prior limited engagement with Washington on the nuclear issue, the Trump administration has continued to insist on zero enrichment and also sought limits on Iran's ballistic missile program.

But then the June war happened and all official dialogue has been off. President Trump has all along proclaimed the end of Iran's ability to enrich, and it is significant that Tehran is now admitting this is accurate.

However, it could also be a bluff. Iran now has every incentive to develop secret nuclear weapons while telling the world there is no enrichment happening.

Many analysts say that another round of fighting between Iran and Israel could be on the horizon. For starters, the Netanyahu government does not believe that Iran has given up its enrichment efforts, but Tel Aviv is likely being held back by the Trump White House.

Iran’s Hidden Nuclear Push Resumes Under Pickaxe Mountain

  • Iran is blocking IAEA access to key nuclear sites, including Fordow, Natanz, and the nearby Pickaxe Mountain.

  • Western intelligence fears Iran may be rebuilding centrifuge facilities or creating a new undeclared enrichment site.

  • The E.U. expects escalating tensions as Iran boosts its defense budget by 200% and accelerates long-range missile development

Iran is blocking the International Atomic Energy Agency (IAEA) from inspecting multiple sites of interest in its nuclear weapons development programme, a senior source in the European Union’s (E.U.’s) security complex exclusively told OilPrice.com late last week. “These include the major sites targeted during the U.S. and Israeli strikes on its nuclear programme facilities in June, including Fordow and Natanz, and another site in particular -- close to Natanz that seems to be the focus of significant Iranian activity since then,” he said. “The pace has picked up even more since the ‘Snapback Sanctions’ were reimposed,” he added. So, what is Iran doing that it does not want the IAEA or anyone else to see, and what have the newly reimposed sanctions going to do with it?

August 28 saw the U.K., France, and Germany (the ‘E3’) begin the process of triggering the ‘snapback’ mechanism of restoring sanctions on Iran for its “significant non-performance” in meeting the terms of the Joint Comprehensives Plan of Action (JCPOA, or colloquially ‘the nuclear deal’) agreed between Iran and the P5+1 group of nations (the U.S., U.K., France, Russia, and China, ‘plus’ Germany) in 2015. At the end of the 30-day period, with no blocking resolution adopted, the sanctions legally snapped back into force. These included an arms embargo, a ban on uranium enrichment and reprocessing, a ban on launches and other activities with ballistic missiles capable of delivering nuclear weapons, a ban on ballistic missile technology transfer and technical assistance, a targeted global asset freeze and a travel ban on Iranian individuals and entities. They also gave authorisation for countries to inspect Iran Air cargo and the cargoes of Iran’s Islamic Republic of Iran Shipping Lines for banned goods. Further sanctions relate to measures connected to the Financial Action Task Force (FATF). This has 40 active criteria and mechanisms in place to prevent money laundering -- an activity that is vital to Iran’s Islamic Revolutionary Guards Corps’ (IRGC) activities across the world, as analysed in full in my latest book on the new global oil market order. It also has nine criteria and mechanisms in place to do the same for the financing of terrorism and related activities -- again, a core of the IRGC’s role in promoting Iran’s brand of Islam around the globe. The FATF also has sweeping powers to wield against individuals, companies, or countries that transgress any of its standards and is extremely aggressive in using them by degrees, depending on whether the sanctioned entity is on its ‘grey’ or ‘black’ list

In response to this – and to the earlier U.S. and Israeli attacks on its sites connected to its nuclear weapons development programme -- Iran’s official stance has been that it is prepared to re-engage with the U.S. in talks aimed at constructing a new ‘nuclear deal’ of some kind, although it is “not in a hurry” to do so. This is despite a significant deterioration in the country’s economy, including projections that the unemployment rate in the key ‘Under-35’ demographic will hit 44% by the end of 2026, according to the E.U. source. Unofficially, according to a senior energy source who works closely with Iran’s Petroleum Ministry and exclusively spoken to by OilPrice.com last week, pressure is growing from the IRGC on Supreme Leader Ali Khamenei to expedite the rebuilding of those key elements in the nuclear programme that were damaged in June. Additional pressure is coming from the same quarters for the Supreme Leader to approve Iran’s formal withdrawal from the ‘Nuclear Non-Proliferation Treaty’ (NPT). “[Iranian President, Masoud] Pezeshkian has said that [Iran] won’t leave [the NPT], but it’s what the Supreme Leader thinks and does that is relevant here,” he said. “The NPT is crucial because the CSA [Comprehensive Safeguards Agreement] – which is overseen by the International Atomic Energy Agency -- is linked to the NPT, and Iran cannot advance its nuclear programme at this point without new builds [of nuclear facilities] and it can’t do this with the IAEA sniffing around on the ground,” he added.

The key reason why the IRGC is pushing for Iran’s withdrawal from the NPT is that all the new measures that would be included in any new nuclear deal negotiated now with the U.S. – from Iran’s current position of weakness – would be targeted at the eventual eradication of the IRGC as we know it, as also detailed in full in my latest book. “Washington has long made it clear – even under [former U.S. President, Barack] Obama -- that it wants the broader powers of the IRGC removed and for it to be rolled into the regular Iranian army,” said the E.U. source. “For the IRGC, and the Supreme Leader, this would remove the force from its primary role of protecting the legacy of the [1979 Iranian] Revolution and undermine the core purpose of that new Islamic order,” he added. “It’s the IRGC’s view that Iran needs to up the ante, and the best way for doing that right now is to leave the NPT, or at least make very serious threats to do it,” he underlined.

Prior to the June military strikes by the U.S. and Israel, the IAEA stated in February that Iran had further increased its stockpile of enriched uranium even after the Agency had announced just three months before that the Islamic Republic had been “dramatically accelerating enrichment of uranium”. According to the IAEA, Iran’s stock of uranium refined to up to 60% in the form of uranium hexafluoride grew by 92.5 kg from December 2024 to February 2025 to 274.8 kg. It underlined that the 60% level of purity was very close in practical terms to the 90% or so weapons-grade benchmark. The Agency added that the 274.8 kg of 60%-enriched uranium Iran had even then was sufficient, if enriched further, for six nuclear bombs, and that there was enough for more weapons at lower enrichment levels. That said, Iran’s Foreign Minister Abbas Araghchi said earlier this month that this figure had since increased to around 400kg, but that “almost all” of that was “buried under the rubble” of nuclear facilities bombed by the U.S. and Israel. He added: “We have no intention of removing them from under the rubble until conditions are ready. We have no information on how much of the 400kg is untouched and how much is destroyed, and we will have no information until we dig them out.”

The problem with that is that Washington, Tel Aviv, London, and Brussels are not so sure. They have little doubt that considerable damage was done to several key Iranian nuclear installations – most notably perhaps, at the Fordow uranium enrichment facility, located in a mountain near Qom. However, this is still one of the sites to which the IAEA has not been granted access since the June attacks, so even this is not fully corroborated. The same is true of another such site close to Natanz and its associated facilities, with one of these in particular having come under close international scrutiny in recent days. The Institute for Science and International Security highlighted in early October that satellite imagery of Pickaxe Mountain (Mount Kolang Gaz-La) – a site around a mile south of the Natanz enrichment facility, that has been under construction since about 2020 -- shows that Iran is continuing construction activities there, although it did not characterise this as an expansion of the site. At the end of last month, the Center for Strategic and International Studies reported satellite imagery showing a significant uptick in mining and drilling into the mountain, and the construction of a huge security perimeter around the site. The Center has posited that there are three explanations for this. The first is that Iran is preparing for a centrifuge assembly facility. The second is that the Pickaxe Mountain site has been expanded to include some of the facilities and research and metallurgy that the U.S. destroyed at Isfahan. And third, that it may be a future uranium enrichment site that Iran is building undeclared.

“The fact that we can’t answer any of these questions on this site, and on many others, sets Iran and us [the E.U., U.S., Israel, and Great Britain] on a collision course again, with more sanctions being the next step, after which we will have to reassess our options,” added the E.U. source. “This is likely to get worse quite quickly, as Iran will increase its military budget by more than 200% next year, with much of this to go on fast tracking the development of intercontinental ballistic missiles with multi-warhead delivery systems with a range of up to 10,000 kilometres,” he said. “[Supreme Leader, Ali] Khamenei is determined to take the missile delivery systems at least to the level of North Korea when it began intercontinental ballistic missiles with multi-warhead capabilities for the first time,” he concluded.

A research team has developed a synthetic microbial consortium that completely reduces soluble uranium [U(VI)] to insoluble U(IV) within 48 hours, showing nearly twice the efficiency of a single-strain system. The study reveals how Shewanella oneidensis MR-1 and Pseudomonas aeruginosa LXZ1 cooperate to accelerate extracellular electron transfer (EET). P. aeruginosa LXZ1 secretes pyocyanin, which interacts with the outer-membrane cytochrome OmcA in MR-1, while its extracellular DNA forms conductive networks within the biofilm. These mechanisms jointly enhance electron flow and energy metabolism, overcoming the limitations of conventional microbial reduction. The findings highlight a community-based approach for sustainable uranium bioremediation.

Uranium contamination from mining and natural leaching threatens groundwater safety due to the high solubility and mobility of hexavalent uranium [U(VI)]. Bioreduction by dissimilatory metal-reducing bacteria converts soluble U(VI) to insoluble U(IV), offering an environmentally friendly remediation strategy. However, this process is often limited by low redox mediator production and poor biofilm conductivity in single-species systems. Synthetic microbial communities that combine complementary metabolic and electron-transfer functions may provide a more efficient alternative. Due to these limitations, it is necessary to investigate cooperative microbial systems that can achieve faster and more complete uranium reduction.

A study by the University of South China and Xi’an University of Technology, published (DOI: 10.1016/j.ese.2025.100629) in Environmental Science and Ecotechnology in October 2025, reports a synthetic microbial consortium capable of complete uranium reduction within 48 hours. The system combines Shewanella oneidensis MR-1, a model metal-reducing bacterium, with Pseudomonas aeruginosa LXZ1 isolated from uranium-contaminated soil. Through electrochemical experiments, molecular simulations, and gene expression analysis, the researchers revealed how phenazine-mediated electron transfer and extracellular DNA jointly improve the efficiency of microbial uranium reduction.

The researchers co-cultured S. oneidensis MR-1 with P. aeruginosa LXZ1, forming a synthetic microbial community that removed 75% of uranium within 12 hours and achieved complete reduction after 48 hours, compared with 60% by MR-1 alone. This improvement arose from two complementary mechanisms. P. aeruginosa LXZ1 secreted pyocyanin, a redox-active phenazine, which bound to MR-1’s outer-membrane cytochrome OmcA and shifted its redox potential, facilitating directional electron flow and reducing proton-transfer constraints. Meanwhile, P. aeruginosa LXZ1 released extracellular DNA (eDNA) that organized into conductive structures, enhancing electron transport across the biofilm. Electrochemical gating tests showed a fourfold increase in current output, which decreased sharply after DNase I digestion, confirming the essential role of eDNA. Transcriptomic results indicated upregulation of metabolic and EET-related genes (ldhndhfdhpflBackA), along with higher NAD⁺/NADH ratios and ATP levels. Together, these processes established a stable and efficient electron-transfer network for uranium immobilization.

“Our results show how naturally occurring microbial interactions can be used to improve metal reduction efficiency,” said Dr. Xizi Long, corresponding author of the study. “By combining Shewanella and Pseudomonas, we achieved a balance between metabolic complementarity and electron transfer enhancement. Pyocyanin functions as an intercellular redox mediator, while extracellular DNA provides a conductive matrix. This cooperative design illustrates how microbial communities can be organized for more effective environmental remediation.”

The synthetic microbial consortium offers a feasible and sustainable method for uranium-contaminated soil and groundwater treatment. Its design demonstrates how interspecies electron exchange can improve the stability and conductivity of biofilms, potentially extending to other redox-active pollutants such as chromium, arsenic, or technetium. Beyond environmental cleanup, the findings deepen understanding of microbial electrochemical cooperation and may inform future developments in bioenergy conversion and microbial material design. This approach exemplifies how ecological cooperation principles can be applied to optimize bioremediation efficiency in complex environments.
