Global fund managers see this year’s surge in nuclear stocks continuing, on an improving regulatory outlook and demand drivers that extend beyond the voracious needs of artificial intelligence.

A Bloomberg gauge of nuclear stocks has jumped 38% in 2025, touching an all-time high and adding $566 billion in total market value. Shares of California-based small reactor builder Oklo Inc. have surged around 400%, while those of Korean equipment maker Doosan Enerbility Co. are up more than 330%.
