The Uranium Squeeze: Big Tech's Nuclear Bet Meets a Fuel Crisis

Big Tech is pouring hundreds of billions into AI data centers. But there's a problem nobody in Silicon Valley wants to talk about: the fuel that powers the nuclear plants they're betting on is running out — and the biggest supplier just got banned.

Uranium spot prices have surged 23% year-over-year to $86.20 per pound, with long-term contracts hitting $90 — the highest since 2008. Behind the numbers is a structural supply deficit that's widening by the month, a geopolitical standoff cutting off America's largest enrichment supplier, and a wave of demand that no amount of VC funding can wish into existence.

This isn't a commodity cycle. It's a strategic chokepoint — and the investors who understand it first will be positioned for what comes next.

The Demand Shock Nobody Priced In

The nuclear renaissance is no longer a talking point — it's a capital expenditure reality.

Microsoft signed a 20-year, $16 billion power purchase agreement with Constellation Energy to restart Three Mile Island's Unit 1 reactor, specifically to feed its AI data centers in Pennsylvania. Amazon acquired a data center campus next to Talen Energy's Susquehanna nuclear plant for $650 million, locking in nearly 1 gigawatt of nuclear capacity through 2042. Google cut a deal with Kairos Power for 500 megawatts from a fleet of small modular reactors.

In total, Big Tech has contracted over 10 gigawatts of new nuclear capacity in the United States alone over the past year. That's roughly the output of ten large nuclear plants — and most of them haven't broken ground.

The scale is staggering. Amazon's "Project Spectrum" in Texas, its $12 billion Louisiana data center push, and its Maryland proposal near Calvert Cliffs all integrate nuclear power. Google is funding three separate 600-megawatt nuclear sites through Elementl Power. Microsoft is collaborating with Nvidia on AI-optimized nuclear development.

These aren't speculative bets. These are binding contracts with delivery dates in the 2028–2035 window — and every single one of them assumes a reliable uranium fuel supply that doesn't currently exist.

The Supply Side Is Broken

Global uranium mine production trails reactor demand by roughly 20 million pounds per year. That deficit has been masked for over a decade by drawdowns from Cold War-era stockpiles and secondary supplies. Those buffers are running out.

Kazakhstan — which produces 43% of the world's uranium — has been cutting targets. Kazatomprom, the state-owned producer, has repeatedly revised production forecasts downward, citing sulfuric acid shortages and geological challenges. Canada's McArthur River mine, the world's highest-grade deposit operated by Cameco, has faced its own delays ramping back to full capacity after years of shutdowns.

In the United States, the picture is even bleaker. American reactors consume roughly 47 million pounds of uranium annually. Domestic mines produce fewer than 8 million. The gap — nearly 85% of fuel needs — must be imported.

And this is where geopolitics turns a tight market into a potential crisis.

The Russia Problem

Until recently, Russia supplied roughly 25–27% of America's enriched uranium fuel. Not just raw yellowcake — the enriched, reactor-ready low-enriched uranium (LEU) that keeps the lights on.

In May 2024, the U.S. enacted the Prohibiting Russian Uranium Imports Act, banning LEU produced by Russian entities. The ban took effect in August 2024, with temporary Department of Energy waivers allowing a phase-out period through at least early 2026. By January 2028, all waivers expire. No new Russian imports after that.

Russia retaliated in November 2024 with its own export ban to the United States, revoking licenses and allowing only case-by-case approvals.

The problem: American enrichment capacity covers only about 30% of domestic demand. The gap previously filled by Russia now needs to come from somewhere — but new enrichment facilities take years to build and billions to fund.

Washington allocated $2.7 billion in federal funding to expand domestic nuclear fuel production, including contracts to Centrus Energy and European partners. But the timeline reality is brutal. New enrichment capacity won't come online at scale until the late 2020s at the earliest, and the advanced fuel (HALEU) needed for next-generation reactors is even further behind.
