Oklo Inc stock dropped 7.75% as investors weigh the company’s nuclear energy progress against financial uncertainties. The decline comes after a major insider sale and mixed analyst reactions to the company’s recent developments.

Director Michael Klein Stuart, who owns more than 10% of Oklo, sold 50,000 shares worth $6.6 million on September 22. The sale happened through two transactions executed at different price points.
The first batch involved 40,000 shares at a weighted average price of $133.40 per share. These trades ranged from $133.26 to $133.57 per share, totaling $5.34 million.
Klein then sold another 10,000 shares at $135.20 each, bringing in $1.35 million. The shares were held through M. Klein Associates, Inc., where Klein serves as controlling stockholder.
After the sales, Klein still indirectly owns 150,000 Oklo shares. The timing of these transactions raises questions given Oklo’s recent 500% year-to-date surge.
Oklo currently trades with a market cap of $19.39 billion despite being a pre-revenue company. This valuation has drawn scrutiny from Wall Street analysts who question the sustainability of such levels.
Nuclear Progress Moves Forward
The company recently broke ground on its first Aurora Powerhouse reactor at Idaho National Laboratory. This project represents a key milestone in Oklo’s nuclear energy ambitions.
The reactor is part of the Department of Energy’s Reactor Pilot Program, which aims to reduce execution risks. Oklo expects to complete the project by late 2027 or early 2028.
Beyond the Idaho facility, Oklo announced plans for a major investment in Tennessee. The company will spend up to $1.68 billion on a nuclear fuel recycling and fabrication facility in Oak Ridge.
This Tennessee facility will focus on producing high-assay low enriched uranium fuel. The investment shows Oklo’s commitment to controlling its entire nuclear fuel supply chain.
Analyst Opinions Remain Split
Wall Street analysts have delivered mixed verdicts on Oklo’s recent moves. Seaport Global Securities downgraded the stock from Buy to Neutral due to valuation concerns.
The downgrade came despite positive business developments at the company. Seaport cited the stock’s rapid price appreciation as a reason for caution.
Wedbush took the opposite approach, raising its price target to $150 from a lower level. The firm maintained its Outperform rating on increased confidence in Oklo’s nuclear strategy.
UBS stayed neutral with a $65 price target, reflecting skepticism about the company’s fuel plans. The wide range of price targets shows the uncertainty surrounding Oklo’s valuation.
Analysts remain concerned about Oklo’s unique own-and-operate business model. This approach differs from traditional nuclear companies and creates new financial risks.
The company’s pre-revenue status adds another layer of uncertainty. Investors must bet on future execution rather than current financial performance.
Oklo’s stock shows technical buy signals despite the recent pullback. The average trading volume has reached over 18 million shares, indicating high investor interest.
The company’s current market cap of $19.36 billion reflects the market’s expectations for nuclear energy growth. Recent nuclear energy agreements between the U.S. and U.K. have boosted sector optimism.
