Oklo Inc. has skyrocketed to a $20 billion market cap, making it the largest pre-revenue company trading in the U.S. — a striking sign of how far investors are willing to go in search of the next big AI trade.
No sales, no problem. Shares of the nuclear technology company (OKLO) sit at $131, up more than 500% this year and nearly 1,500% over the past 12 months. That’s despite the company never booking a single dollar in revenue.
Investors aren’t buying fundamentals — they’re buying a story. And Oklo’s story is tied to AI. The company is developing small modular reactors (SMRs) that could supply the massive power demands of AI data centers. Backed by OpenAI CEO Sam Altman — who took Oklo public via his SPAC AltC Acquisition in 2024 and still owns a 5.5% stake — the stock has captured retail traders’ imagination. On StockTwits, message volume is “extremely high” and sentiment “bullish.”
“It’s a more speculative, growth-focused environment, with falling interest rates, rising markets and higher retail participation,” said Chris Tessin of Acuitas Investments.
Oklo broke ground this week on its first commercial SMR at Idaho National Laboratory under the Department of Energy’s Reactor Pilot Program. Still, Wall Street doesn’t expect revenue until late 2027. Like clinical-stage biotech firms, Oklo faces a binary outcome: either successful commercialization or the risk of its technology becoming worthless.
Other SMR players, like NuScale Power (SMR), have booked modest revenue through engineering and licensing services, but true nuclear power sales remain years away.
Big banks are split on Oklo. Bank of America recently initiated with a buy rating and $92 target, citing its “largest disclosed customer pipeline in the SMR space.” Wedbush’s Dan Ives is even more bullish, raising his target to $150. UBS analyst Jon Windham took a longer view, setting a $65 hold rating, noting steady growth may not arrive until 2034. Seaport’s Jeff Campbell struck a cautious note, downgrading the stock to neutral due to stretched valuation.
For now, Oklo is the ultimate “story stock” — a nuclear-powered AI dream that has captivated Wall Street and Main Street alike. The question is whether investors will wait nearly a decade for the company to turn that story into steady revenue.
