Oklo is trading 12.89% up at $47.67 after its Groves Isotope Test Reactor achieved first criticality in Texas on August 5, announced August 6.

  • A controlled, self-sustaining chain reaction under the U.S. Department of Energy’s Reactor Pilot Program marked its first privately built reactor on greenfield land.
  • The milestone provides major technical validation and is the clearest explanation for the sharp move.
  • Strong August 7 intraday momentum followed a 4.20% premarket gain; markets were mixed or weaker.
