The artificial intelligence boom is unexpectedly benefiting the utilities sector, driving up power demand and stock prices. The S&P 500 Utility Index has rallied over 10% this year, making it one of the top-performing sectors. Companies like Vistra and Constellation Energy have seen significant gains, with valuations remaining attractive as earnings keep pace. However, power capacity concerns and the need for infrastructure investment could impact the sector's growth. If addressed, utilities are expected to continue their strong performance, potentially boosted by declining interest rates.
