If you're just noticing nuclear stock Oklo (OKLO +4.96%), you might be looking at its year-to-date performance through burning eyes.
The stock is up over 450% on the year, putting the company's market cap at about $18 billion. Investors might balk at a stock that's already seen such extraordinary gains, let alone a company like Oklo, which has no revenue and no reactor in operation.
For aggressive investors with a long time horizon, however, it might not be too late to capture upside from this nuclear darling.
Microreactors are built for this moment

Like other reactors, Oklo's powerhouses can provide reliable 24/7 power to clients. Unique to them, however, is the specialized fuel they will use, which could leave them operating for a decade or more without refueling.
Because of their size, Oklo's powerhouses will take less time (and money) to build. That, plus the reliability of their power, make them ideal companions to AI data centers, which is one reason Sam Altman has been an early supporter of Oklo.
All of this has contributed to Oklo's multibillion-dollar valuation. To grow from here, however, the company needs two major things to happen: It needs to make money, and it needs regulatory approval to commercialize its reactors.

Key Data Points
On the revenue side, Oklo recently acquired Atomic Alchemy, a radioisotope start-up. If successfully integrated, the business could generate revenue from radioisotope production as early as 2026. Oklo values the radioisotope market at about $55.7 billion, which sounds promising but is still just a projection.
Getting regulatory approval is still the big question mark. The company has been moving through an accelerated timeline, with the goal of turning on its first reactor in 2027. If it can switch on the revenue stream in 2026, it could bolster its cash position, which was about $227 million at the end of June.
If Oklo can execute on these (and that's still an if), patient investors could see more growth over the next decade.
