S&P 500 component Constellation Energy announced Thursday it is in discussions with major companies to provide nuclear power for artificial intelligence (AI) data centers, with projects expected to scale up through the decade. Constellation Energy reported on its first-quarter earnings call Thursday that data centers at its nuclear reactors could come online in 2026-2028 and ramp up from there. "The data economy and Constellation's nuclear energy go together like peanut butter and jelly," Chief Executive Joe Dominguez said Thursday on the earnings call.
