The stock opened with a 2.0% gap up and reached a session high of $48.50 by the close of the trading day.

What Happened

Oklo and X-Energy have been selected to participate in a program led by the Trump administration aimed at fast-tracking the development of new nuclear power plants tailored for AI data centers. Bloomberg reported the initiative, which includes collaboration with major technology firms. The news comes as part of a broader industry push to secure reliable energy sources for high-demand computing applications. The involvement of Oklo, a pre-revenue company with a market cap of $7.2 billion, has drawn attention from institutional traders, who are reportedly buying call options on the stock. Options trader Andrew Keene highlighted the move, noting large institutional call buying in Oklo and similar firms, all of which trade at significant discounts to their 52-week highs.

The stock has traded between $42.17 and $48.50 in intraday trading, with volume reaching 8.0 million shares, or 0.7 times the 3-month average. The stock has been volatile recently, falling 9.2% over the past eight sessions. Oklo remains unprofitable, with a trailing twelve-month earnings per share of -0.83. The stock is currently trading within its 52-week range of $39.53 to $193.84. Unusual options activity has also been noted, with a notable call premium of $1.7 million in the last 36 hours. Meanwhile, recent insider transactions show three executives sold shares totaling $55.0 million in the last 90 days.

What To Watch

The stock is currently without an imminent earnings date. Investors should monitor the breadth of institutional interest and any follow-up developments from the Trump administration initiative.
