The overall utilities sector fell by 5.18% during the month of August, compared to the 2.62% gain for the overall market. The sector’s weakness was primarily attributed to a backup in long-term Treasury yields amid rising fiscal deficits and Treasury supply. At the same time, the growing AI-linked corporate debt also added to the competition for investor capital. The August decline pushed utilities into negative territory for the year, making it the only S&P 500 sector to post a year-to-date loss.
Despite the overall sector’s underperformance, Constellation Energy Corporation (NASDAQ:CEG) emerged as a winner in August with gains of just over 5%. The stock’s relative strength appears to reflect its improving fundamentals, particularly its exposure to the soaring power demand from AI data centers and the growing strength of its nuclear fleet.
In addition, Constellation delivered better-than-expected earnings in its Q2 2026 and even raised its full-year adjusted operating earnings guidance range by $0.50 per share, to $11.50 to $12.50 per share.

Nuclear Strength Fuels Constellation’s Upside:
Constellation Energy’s strongest advantage is its ownership of the largest fleet of operating nuclear reactors in the United States, which can provide reliable and clean electricity at a time when power demand is soaring to record highs. The company has leveraged these assets to secure long-term agreements with major technology customers and has also signed more long-term PPAs for 920 MW of nuclear energy for investment-grade customers in the second quarter. These contracts range from 15 to 20 years, providing long-term revenue visibility.
At the same time, Constellation is working on the extension and expansion of its existing nuclear facilities. The company recently filed applications with the Nuclear Regulatory Commission for a 20-year extension of the operating licenses of its Ginna Clean Energy Center and Nine Mile Point Unit 1 reactor in New York to 2049. This will allow the utility to continue capitalizing on the ongoing AI boom without relying exclusively on the lengthy and costly construction of new nuclear plants.
Another major growth catalyst for Constellation is the integration of its recent Calpine acquisition, which expanded the company’s generation portfolio by up to 22 GW through natural gas and geothermal power plants. The company noted in its Q1 earnings call that integrating Calpine contributed roughly $2 per share in accretion to its adjusted EPS, highlighting the deal’s early financial rewards.
AI Bubble Threatens CEG’s Growth:
Beyond regulatory and execution challenges, the concerns of a potential AI bubble present a significant risk for Constellation Energy, since a major part of its investment thesis is based on the rapidly growing power demand from data centers.
While hyperscalers are currently committing hundreds of billions of dollars to expand their data center infrastructure, the long-term returns on these investments remain uncertain. Any meaningful slowdown in AI adoption, weaker-than-expected returns, or a subsequent pullback in capital spending could significantly reduce the projected power demand and weaken one of Constellation’s key growth drivers.
Conclusion:
Constellation Energy’s outperformance in August highlights the market’s growing confidence in its nuclear-focused growth strategy. The company’s strong earnings, long-term power agreements, and the soaring AI-driven electricity demand further add to its appeal. However, investors should remain mindful that a potential slowdown in AI spending could weaken the data center power demand and weigh on Constellation’s growth prospects.
Market Sentiment:
Constellation Energy Corporation was held by 73 hedge funds in the Insider Monkey database at the end of Q2 2026, with a total investment value of just under $2.7 billion. This is down from 79 hedge fund investors with a total stake value of almost $3.38 billion in the previous quarter.
