Why is Oklo stock surging today?
Oklo's stock rose 7.6% in pre-market trading after the U.S. Department of Energy lifted operational restrictions on its Groves-1 reactor, allowing research and testing. The company reported Q3 2026 revenue of $1.86M, exceeding estimates, and analysts maintained positive ratings. The broader market backdrop was mixed but improving. This milestone advances Oklo's commercialization plans.
