Why These Energy Stocks are Losing This Week

3. Oklo Inc. (NYSE:OKLO)

Share Price Decline Between Dec. 23 – Dec. 30: 12.53%

Backed by OpenAI’s Sam Altman, Oklo Inc. (NYSE:OKLO) develops advanced fission power plants to provide clean, reliable, and affordable energy at scale to customers in the United States.

Oklo Inc. (NYSE:OKLO) garnered massive investor attention during the AI boom as its Aurora small modular reactor, considered on the bleeding edge of nuclear technology, emerged as a potential solution to power the booming data center industry. The nuclear startup also managed to win multiple contracts from the Department of Energy, and as a result, its share price has shot up by an impressive 228% since the beginning of 2025.

However, Oklo Inc. (NYSE:OKLO) still needs regulatory approval for deploying and operating its reactors, and the process could take two to three years. As a result, the company still has zero revenue and isn’t expected to report any until at least 2027. Even then, it is projected to generate about $16 million, which is worrisome for a company that currently has a market cap of almost $11.2 billion.

The recent plunge in share price reflects investor concerns that Oklo Inc. (NYSE:OKLO)’s triple-digit gain over the last year may have been driven more by investor enthusiasm than by fundamentals. Moreover, recent fears of an AI bubble have further reinforced this sentiment, prompting investors to adjust their expectations somewhat.
