Hyperscalers Turn to Nuclear for AI Power as Grid Strains Mount
The shift away from intermittent renewables and natural gas has sparked a surge in nuclear-focused exchange-traded funds, with returns exceeding 60 per cent over the past year.
Major technology firms Microsoft, Amazon and Google have executed direct power purchase agreements with utilities and small modular reactor developers to secure round-the-clock baseload electricity for their expanding artificial intelligence infrastructure. This strategic move addresses severe grid constraints in Virginia, Texas and the Pacific Northwest, where hyperscalers require a zero-carbon power source that avoids the storage costs associated with renewables or the carbon emissions of natural gas.
Driven by the need for firm, continuous power that intermittent sources cannot provide economically, these companies view nuclear energy as the only scalable solution capable of meeting their specific demand profile. Consequently, the surge in demand has led to significant appreciation for nuclear-focused exchange-traded funds, including the Sprott Uranium Miners ETF, the Range Nuclear Renaissance Index ETF and the Themes Uranium and Nuclear ETF.
The Sprott Uranium Miners ETF has risen approximately 89 per cent over the past year, holding significant concentrations in Cameco, the Sprott Physical Uranium Trust and NexGen Energy. This fund offers the most direct leverage to rising uranium prices, with its portfolio leaning heavily on a small group of names that make up nearly half of its net assets.
In contrast, the Range Nuclear Renaissance Index ETF has gained about 73 per cent by taking a broader view of the sector. It holds reactor operators, small modular reactor developers and engineering firms alongside miners, capturing the full value chain from fuel demand to new-build work and utility contracts.
The Themes Uranium and Nuclear ETF has returned roughly 65 per cent, offering a blended, lower-cost alternative with a global mix of miners and nuclear companies. While it trades with wider bid-ask spreads than its larger peers, it serves as a reasonable substitute for investors seeking exposure without the premium associated with category-leading assets.
These performance figures reflect the underlying supply-demand setup where data centre load growth has broken previous grid-planning assumptions. As operators restart retired reactors and sign long-dated offtake agreements with cloud providers, the investment case for these funds flows directly from the expectation that uranium prices and nuclear buildout will continue to climb.
