Who makes uranium for AI data centers

Uranium mining is the front of the nuclear chain and the part of it that behaves most like a commodity business. Producers extract ore, mill it to concentrate, and sell into a market that has spent much of the last two decades with more supply than demand — which is why a meaningful share of global production capacity sat idle and why restarting it is not instantaneous. The demand side has changed on paper faster than the supply side can respond. Life extensions on existing reactors, new build in several countries, and the advanced-reactor programmes in the sibling parts of this catalog all point the same way, and AI operators contracting for nuclear power add to it. Mine development runs on a decade-scale timeline from discovery through permitting to production, so near-term response comes from restarting idled capacity rather than opening new mines. For this catalog, the honest framing is that uranium is the most distant link between an AI data center and the physical world — several steps removed, and driven by far more than data center demand. Production is also geographically concentrated in a small number of countries, which is a political exposure as much as a geological one. What to look for is producing capacity versus resource in the ground, the difference between a restart and a new mine, and how much of a producer's output is already committed under long-term contract rather than available.
