Oklo (OKLO) falls as first-quarter loss widens despite Nvidia (NVDA) partnership

Oklo (OKLO) shares fell 2% Wednesday morning, May 13, 2026, after the nuclear reactor developer reported a wider first-quarter loss, underscoring investor concerns over execution and costs. The company posted a loss of $0.19 per share on May 12, matching analyst expectations but widening from a $0.07 per-share loss in the year-earlier period. Oklo shares are down roughly 5% year to date. Oklo has benefited from U.S. government efforts to accelerate nuclear power development, including systems for space missions. In April 2026, the company announced a partnership with Nvidia (NVDA) and Los Alamos National Laboratory to work on next-generation nuclear power. CEO Jacob DeWitte said on the May 12 earnings call that Oklo has built a customer pipeline across data centers, industrials, energy and government customers since going public.
