America’s nuclear sector just received something rarer than bipartisan kumbaya on Capitol Hill: a first-of-its-kind commercial construction permit for an advanced reactor, signaling that the atomic age is getting a sequel with better graphics, tighter scripting—and, this time, a climate mandate. For Wall Street and Silicon Valley alike, the message is straightforward: the Nuclear Regulatory Commission is no longer a museum; it is open for new business in electrons.
Gates’ TerraPower Steps Onto Center Stage
At the center of this shift is the Natrium project in Kemmerer, Wyoming, developed by TerraPower, the nuclear innovation company founded by Bill Gates. The Natrium design is a 345 megawatt sodium-cooled fast reactor paired with a molten-salt energy storage system that can flex output to 500 megawatts—enough to power roughly 400,000 homes during peak periods. That built-in storage allows the plant to ramp like a battery while still behaving like dependable baseload, giving grid operators the kind of dispatchable, carbon-free power they usually only dream about in PowerPoint.
The Wyoming site, being built near a retiring coal plant, is the country’s flagship “coal-to-nuclear” conversion and the first utility-scale advanced nuclear project to clear a full environmental impact statement from the NRC with a recommendation that a construction permit be issued. For a technology class long trapped in pilot purgatory, breaking ground on a next-gen plant backed by Gates amounts to ringing the opening bell on an entirely new subsector of energy infrastructure.
Oklo: Microreactors for the AI Era
If TerraPower’s Natrium is the blue-chip utility play, Oklo (OKLO) is the growth stock pitching nuclear as a product for the AI age. Oklo is developing compact fast reactors—initially sub-100 megawatt units—that are designed to be factory-built, sited close to customers, and capable of running for years without refueling, eventually on recycled nuclear material. The goal is simple and audacious: turn nuclear power into something you buy in modular increments rather than as a once-in-a-generation mega-project.terrapower+1
That vision is already attracting data-center scale demand. Oklo has signed a framework agreement to deliver up to 12 gigawatts of nuclear capacity to Switch, a major data center operator whose client list includes the likes of Google and Nvidia, envisioning a fleet of microreactors rolled out through the 2040s. In parallel, Meta has lined up nuclear partnerships with Oklo, TerraPower, and others to secure roughly 6.6 gigawatts of power for its AI data centers by 2035—roughly the consumption of an entire small country. In effect, Oklo is sketching the blueprint for nuclear-powered digital campuses where the plant and the racks are designed as a single ecosystem, not separate line item.
Microsoft, Gates, and the AI Power Squeeze
All of this is unfolding against an uncomfortable arithmetic problem: AI is devouring electricity faster than grids can comfortably supply it. Forecasts suggest that data center demand could roughly double mid-decade, with AI-capable capacity growing north of 30% annually through 2030. Bill Gates has been blunt that nuclear energy is one of the few technologies capable of meeting that surge while keeping emissions in check, and TerraPower has already inked deals to serve next-generation data centers in regions where local power systems are stretched.
Microsoft, the company Gates co-founded and still influences as its most prominent alumnus, is increasingly vocal about needing new nuclear to power its cloud and AI ambitions, even going so far as to recruit small modular reactor expertise and explore nuclear-backed data center projects. That creates a neat symmetry: on one side, Gates’ TerraPower is building flexible, utility-scale reactors like Natrium; on the other, advanced players such as Oklo are designing microreactors and nuclear campuses that can plug almost directly into hyperscale facilities from Microsoft and its peers.
The result is a new strategic map where “compute” and “kilowatts” are no longer separate boardroom conversations. TerraPower’s Natrium plant in Wyoming shows that advanced reactors can clear regulatory hurdles and break ground; Oklo’s multi-gigawatt data center deals show that hyperscalers are ready to be anchor tenants; and the AI power squeeze ensures that Microsoft-level demand for firm, clean energy is not a passing fad but a structural feature of the next decade. For investors, the punchline is that nuclear is quietly reinventing itself as the backbone of the AI grid—with Bill Gates’ TerraPower providing the marquee project, Oklo supplying the modular edge, and Microsoft and its Big Tech cohort emerging as the sector’s most important new customers.
