Oklo Is Down 61% This Year Despite a Real Technical Milestone. Here's the Disconnect Between the Stock and the Science.

Oklo stock has plummeted 61% in 2026 as investor enthusiasm for nuclear energy and AI infrastructure spending has waned. However, the company has achieved significant technical milestones including first criticality of its Groves test reactor in Texas and NRC approval of design criteria for its Aurora powerhouse. Despite progress toward commercialization, Oklo remains unprofitable and cash-burning, with its 2028 launch target uncertain. The stock is considered speculative and suitable only for aggressive investors.
