Oklo’s Soaring Stock Reverses, Down 40% After Q3 Loss at Pre-Revenue Reactor Maker

Analysts expect the company’s first revenue no earlier than 2027.

Overview

  • Oklo shares climbed roughly ninefold to a $166 peak in mid-October before sliding about 40% over the past month.
  • Q3 2025 results showed zero revenue and rising expenses, with $36.3 million in operating costs in the quarter and $82.2 million year to date.
  • The company reported approximately $923 million in cash and equivalents, with an implied annualized cash burn of about $73 million.
  • In October, the Department of Energy selected Oklo for three Advanced Nuclear Fuel Line Pilot Projects, adding to earlier DOE awards to build nuclear power plants.
  • Investor enthusiasm linked to potential AI data center demand contrasts with a long commercialization timeline, with analysts seeing cost coverage around 2030 and some suggesting free cash flow may not arrive before 2033.
