About Constellation Energy
Constellation Energy operates the largest nuclear fleet in the United States. It makes money selling the electricity those plants generate, increasingly through long-term contracts with buyers who want reliable, carbon-free power.
Its AI-relevant offerings are power products: nuclear energy for AI data centers, carbon-free compute power, and grid-scale power solutions. The marquee example is its Crane clean energy deal with Microsoft, a restart of a retired reactor to supply an AI data center customer under a long-term agreement.
Formed in 2022 and headquartered in Baltimore, Maryland, Constellation trades on the NASDAQ, is led by CEO Joseph Dominguez, and employs roughly 15,300 people.
Constellation Energy in the AI buildout
Constellation anchors the Power & Energy layer of the buildout. AI data centers need enormous, always-on, carbon-free electricity, and nuclear plants are one of the few sources that fit. Constellation's fleet, the largest in the US, lets it sign long-term deals like the Microsoft Crane restart that convert AI demand into contracted volumes. Its growth story now hinges almost entirely on data center demand lifting power prices and contracts, which is why Supercycle scores its exposure as high.
CEG is tracked in Power & Energy, rated Strategic on the AI Exposure leaderboard.
