CEG's role in the 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.

VST's role in the buildout

Vistra sits in the Power & Energy layer of the AI buildout. Data centers are adding load to markets where Vistra sells power, and its nuclear fleet offers the constant, carbon-free supply AI operators want. The investment case now hinges on AI power demand lifting electricity prices and producing long-term compute-related contracts, which puts the company squarely in the energy leg of the AI trade. Supercycle scores Vistra's AI exposure at 65 out of 100.

Both stocks sit in Power & Energy, so they compete for the same slice of AI spending.
