Constellation Energy vs. Vistra: 2 Very Different Bets on the Same AI Power Boom. Here's Which One I'd Buy.

Constellation Energy and Vistra are both capitalizing on AI-driven electricity demand, with stocks up 137% and 330% respectively over three years. Constellation focuses on nuclear power (22 GW capacity), while Vistra is more diversified with natural gas (62% of capacity) and smaller nuclear operations (15%). The analyst recommends Vistra as the better buy due to its lower valuation (9x 2026 EBITDA vs. Constellation's 21x P/E), greater diversification, and stronger exposure to natural gas, which powers most U.S. data centers.
