Why This Matters
Constellation Energy Corporation (CEG) saw its stock price climb after announcing a landmark 20-year power purchase agreement with Meta on June 3, 2025. The deal, involving 1.1 gigawatts of nuclear energy from the Clinton Clean Energy Center, secures the plant’s future and highlights the tech industry’s shift toward clean energy. This development, trending on X, underscores CEG’s role in meeting rising energy demands, particularly for AI data centers, making it a focal point for investors.
Details of the Meta Agreement
The agreement ensures Meta will purchase the entire output of the Clinton Clean Energy Center’s nuclear reactor starting in June 2027. This commitment supports the plant’s relicensing and continued operation, which was at risk due to the expiration of its zero-emissions credit. The deal also includes a 30-megawatt capacity increase through plant uprates, preserving 1,100 jobs and generating $13.5 million in annual tax revenue, per Constellation Energy.
Stock Market Reaction

CEG stock opened at $342.00 on June 3, 2025, up from a previous close of $313.43, and hit a high of $358.47 before settling at $321.49 by mid-morning, a 2.57% gain. This volatility reflects strong initial investor enthusiasm, likely tempered by profit-taking, as the stock outperformed the S&P 500’s 0.92% daily return. The market cap stood at $96.86 billion, per finance data.
Industry Trends and Nuclear Energy
The Meta deal reflects a broader trend of tech giants like Amazon, Google, and Meta partnering with nuclear energy providers to power data centers. In March 2025, these companies pledged to triple global nuclear energy by 2050, per CNBC. Nuclear power’s reliability makes it ideal for AI-driven energy demands, positioning CEG as a key player in the clean energy transition.
Future Outlook
With this contract, CEG strengthens its position as America’s largest emissions-free energy producer. Analysts maintain a “Buy” rating, though the 12-month price target of $291.54 suggests caution due to high valuations, per Stock Analysis. The deal’s success could prompt further partnerships, but regulatory hurdles and market risks remain concerns.
