On May 26, Constellation Energy Corp rose 3.36% in regular trading, trading at $306.305/share, with trading volume of $167 million.

The rally was driven by a combination of sustained optimism around AI-related electricity demand and the lingering positive impact of the U.S. Department of Energy emergency order issued earlier. The DOE directive instructed regional grid operator PJM Interconnection to coordinate with Constellation Energy to ensure critical generating units at its Eddystone power station in Pennsylvania remain operational, underscoring the company's strategic importance within U.S. power infrastructure and grid reliability.

Within the Electric Utilities sector, Oklo Inc. led gains with a 5.43% rise, while American Electric Power edged up 0.05%, Exelon held flat, NextEra slipped 0.29%, and Southern declined 0.39%. Constellation Energy Corporation is the largest producer of carbon-free energy in the United States, with approximately 33,094 megawatts of generating capacity spanning nuclear, wind, solar, natural gas, and hydroelectric assets, serving distribution utilities, municipalities, and commercial customers nationwide.
