Home / Uranium market
Since 2018 the sentiment towards nuclear energy has improved in the context of net zero carbon commitments, concerns around concentration of supply and an increased focus on energy security following Russia’s invasion of Ukraine. The U3O8 price has started to respond positively as the supply/demand imbalance has become more widely recognised.
Demand side drivers
+ Long-term growth in global electricity demand
+ Strong growth forecast for nuclear in the large developing economies in Asia
+ Low carbon emission energy source supporting 2050/2060 country emission targets
+ Increased focus on energy security in light of geopolitical developments is driving a rethink in energy policies in countries that previously moved away from nuclear
+ Nuclear’s ability to provide reliable and predictable electricity to complement renewable sources
+ Progress in developing small modular reactors (“SMRs”) with reduced capital costs and footprint
+ Increased activity in the spot market from financial intermediaries
+ Contracting by nuclear power utilities for future uranium purchases has started to increase from historically low levels
+ Overhang of secondary supply has largely eroded
+ The growth of data centres and artificial intelligence, which requires greater amounts of reliable electricity
– Resistance regarding perceived potential environmental and safety impact is reducing
Supply side constraints
– Concentrated resources (three countries produce 68% of the world’s annual uranium production) increase the risk of supply disruptions due to geopolitical events or other factors
– Significant historical resources reached end of life in 2021 (Ranger and Akouta)
– Exploration and development of new resources has been uneconomic during an extended period of depressed uranium prices
– Cost inflation, supply chain disruptions for essential inputs and industry skills shortages are affecting producers’ ability to increase production, restart idled capacity and develop new resources
– Producers continue to show discipline at current prices

The front end of the nuclear fuel cycle is a complex process in which uranium can take up to 18 months to travel from mine to reactor*OECD-NEA, The Economics of the Nuclear Fuel Cycle (1994). While there are nuclear reactors in 32 countries around the world*World Nuclear Association/ World Nuclear Power Reactors & Uranium Requirements (May 2023), the majority of uranium production, conversion, enrichment and fabrication take place in relatively few places.
Uranium is mined using in-situ leaching, open pit and underground mining.
Heat from nuclear fission produces steam that drives turbines to generate electricity.
September was an important month for the nuclear energy sector, with developments around the globe pointing to the rapid revival of an energy source once sidelined due to safety and cost concerns.
This month I wanted to look at one of the main factors driving this revival: namely the rise of hyperscale datacentres and artificial intelligence (AI).
As technology giants such as Microsoft and Amazon look to power hugely energy-intensive infrastructure while balancing carbon reduction goals, it has sparked a resurgence of interest in nuclear. And as a result, the uranium market is seeing a parallel rise in demand.
Data centres, which power the modern digital world, are voracious consumers of electricity. The development of AI algorithms, machine learning models, and cloud-based services is also leading to a surge in energy demand.
After five years lying dormant, Three Mile Island in Pennsylvania was thrust back into the spotlight last month, following news that Constellation Energy is to restart and refurbish the 835 Mwe site. The decision, bolstered by a 20-year power off-take agreement with Microsoft, highlights the alignment between corporate climate goals and nuclear energy development.
Additionally, the rise of Small Modular Reactors (SMRs) represents a new frontier in nuclear technology. Oracle’s plan to power a gigawatt-scale data centre with three SMRs further illustrates how the private sector is increasingly leveraging nuclear energy for large-scale, carbon-neutral power solutions to meet this growing demand.
Multiple countries, particularly those in Asia and the Middle East, are expanding their nuclear programmes. South Korea, for example, has issued construction licenses for new reactors, signaling a reversal of its previous nuclear phase-out policy. Meanwhile, in the U.S., the Department of Energy’s analysis suggests that substantial new nuclear capacity could be built on existing and retired nuclear sites, further boosting demand for uranium.
Investor sentiment towards uranium and nuclear energy has also shifted positively. A group of major international banks, including Bank of America, Goldman Sachs, and Morgan Stanley, recently expressed support for the expansion of commercial nuclear power. This endorsement from the financial sector could lead to increased capital flows into nuclear projects, both conventional and SMR-based, further driving uranium demand.
Moreover, nuclear energy offers an essential advantage in the race to meet climate goals. The International Atomic Energy Agency (IAEA) projects that global nuclear capacity could increase by 2.5 times by 2050 to reach 950 gigawatts-electric (GWe), fuelled by the urgent need to decarbonize the global economy. SMRs, in particular, are gaining attention because they can be built faster and at a lower cost compared to traditional reactors, making them a flexible and scalable option for industrial energy users like data centres.
This nuclear revival has triggered a corresponding increase in uranium demand. The global uranium spot market saw stable activity in 2024 to date, with prices rising to $81.75 per pound in September, marking an increase of $3.75 from August. Forward prices are also continuing to strengthen, signalling the market’s reaction to pending green-fields uranium developments which will only occur at higher price levels.
Despite the optimistic outlook, the uranium market is not without risk, not least the obvious geopolitical factors, such as Russia’s role in the global nuclear supply chain, which could create supply disruptions, potentially driving prices higher but also causing market volatility.
As data centres multiply and AI continues to expand, the role of nuclear energy—and by extension, uranium—is poised to expand, perhaps significantly.
I remain positive on the outlook for uranium, bolstered by the global push for clean energy, expanding nuclear programmes, and strong investor interest.
