Is Oklo Stock Worth The Risk?

Oklo stock (NYSE:OKLO), the nuclear energy startup backed by OpenAI’s Sam Altman, has been a stellar performer, rising by over 140% year-to-date in 2025. There’s good reason for the optimism. Oklo is building compact, fast-spectrum microreactors that aim to deliver clean, safe, and cost-effective power, which could be a boon as electricity demand surges, while concerns around climate change and global warming intensify. However, the company is still pre-revenue, with its first commercial reactors not expected to go online until 2028 or 2029. Oklo stock, currently trading around $54 per share with a market cap of about $8 billion, is not just richly valued – it’s somewhat speculative. So what does Oklo do and how does the risk to reward tradeoff look for the stock?

Why Nuclear Looks Attractive

Electricity demand is set to rise sharply in the coming years, and nuclear energy looks like a compelling solution. Unlike intermittent renewables such as wind and solar energy, nuclear offers clean, stable, around-the-clock power. The tech industry is rapidly expanding data centers to support the energy-hungry demands of generative artificial intelligence, while President Trump’s big domestic manufacturing push and a broader shift toward electrification continue to drive up power needs. At the same time, environmental risks are mounting, with global warming calling for cleaner energy sources.

Oklo’s Promising Tech

Oklo is building compact, fast-spectrum microreactors that aim to deliver clean, safe, and cost-effective power. The company’s Aurora line of reactors aims for power capacity ranging from 15 to over 100 megawatts. This is a sharp departure from traditional nuclear power plants in the United States, which average about 1,000 megawatts. This translates into a smaller and much more flexible footprint. The reactors use fast neutrons and liquid-metal cooling, avoiding the complexity of high-pressure systems while improving fuel efficiency and safety.

One of Oklo’s signature innovations is its use of recycled nuclear waste as fuel, transforming a long-standing challenge into a valuable clean energy resource. With 10-year running times and no need for handling fuel on site, these microreactors could be well-suited to remote and high-demand use cases such as AI data centers, industrial sites, and defense installations. The company intends to sell electricity and not power plants, directly to customers under long-term contracts. This should provide recurring revenue and profits.

Regulatory Tailwinds

The U.S. regulatory environment also appears to be shifting in favor of advanced nuclear projects. Recent executive orders from President Trump aim for a fourfold increase in nuclear capacity from 100 GW to 400 GW by 2050. Notably, the Nuclear Regulatory Commission is undergoing streamlining, with new regulations mandating reactor licensing decisions within 18 months. These adjustments are intended to accelerate the rollout of advanced technologies such as those developed by Oklo. Additionally, the U.S. Department of Defense is becoming a key customer for Oklo, engaging the company to provide its reactor technology to power the Eielson Air Force Base in Alaska.

Risks

However, with no meaningful revenues expected until at least 2028, Oklo will be burning through significant cash to fund its R&D, licensing, and operational build-out over the next several years. The company had about $260 million in cash and marketable securities as of the end of Q1 2025, while it forecasts an annual cash burn of $65 to $80 million for the current fiscal year. At that rate, Oklo has roughly 3 to 4 years of funding runway, assuming that its costs don’t escalate. This means there is a likelihood that equity dilution or additional debt will be needed in the future.

Even if Oklo successfully clears regulatory hurdles, scaling up production and commercial deployment will be a major challenge. Plenty of high-profile energy and hardware startups have stumbled at this very stage, as they struggle to transition from promising prototypes to reliable, real-world performance at scale.

Not comfortable with the risky nature of OKLO stock? You could explore the Trefis Reinforced Value (RV) Portfolio, which has outperformed its all-cap stocks benchmark (combination of the S&P 500, S&P mid-cap, and Russell 2000 benchmark indices) to produce strong returns for investors. Why is that? The quarterly rebalanced mix of large-, mid- and small-cap RV Portfolio stocks provided a responsive way to make the most of upbeat market conditions while limiting losses when markets head south, as detailed in RV Portfolio performance metrics.
