Oklo (OKLO) Stock Falls on Dec. 17, 2025 as Plutonium Test Milestone Collides With Dilution and AI Data-Center Fears
Oklo Inc. shares fell nearly 9% to $76.04 in late U.S. trading on December 17, 2025, despite the company announcing plutonium fast-reactor experiments with Los Alamos National Laboratory. The drop follows ongoing investor concerns over a $1.5 billion at-the-market equity offering disclosed earlier this month.
