Oklo is one of the two nuclear stocks investors are being told to consider buying today, and its pitch rests on a reactor design that looks nothing like the massive plants that have long defined the industry. The company’s Aurora microreactor generates just 1.5 MW on its own, but additional units can be linked to reach as much as 75 MW per deployment.
The system uses metallic uranium fuel pellets and recycles its fuel in a closed loop, a setup Oklo says can keep a reactor running for roughly a decade without refueling. That is the kind of engineering meant to solve one of nuclear power’s oldest problems: how to deliver steady output without the size, cost and complexity that have slowed conventional reactor builds for years.
The weight behind the story is not the technology alone, but the gap between that promise and Oklo’s financial reality. The company has not deployed any of its reactors or generated any meaningful revenue yet, even as analysts expect revenue to rise from less than $1 million in 2026 to $36 million in 2028. At the same time, Oklo is valued at 233 times its 2028 revenue, a level that leaves little room for execution missteps.
That valuation is landing at a moment when the nuclear trade has a very different feel than it did after the 2011 Fukushima disaster, when uranium prices and investor appetite both cooled sharply. The backdrop has changed because demand for cloud computing, data centers and artificial intelligence has revived interest in reliable power, and smaller reactors have become the sector’s main source of momentum. Oklo is trying to ride that wave with a product built for places that need compact, long-duration generation rather than a traditional grid-scale plant.
The friction point is timing. Oklo expects to deploy its first 75 MW Aurora Powerhouse reactor in Idaho in 2027, and it also has a U.S. Department of Defense contract to build a small reactor for Eielson Air Force Base in Alaska. Those are real milestones, but they are still ahead of the revenue curve, which means investors are being asked to pay for a future that has not yet been proven in the field.
For now, Oklo stock is a bet that the company can turn an elegant reactor concept into operating assets faster than the market’s patience runs out.
