Nuclear Stock Face-Off: Is Constellation Energy or Vistra the Better Buy Right Now?

Constellation Energy operates the largest U.S. nuclear portfolio with over 22 GW capacity and has signed major 20-year power agreements with Microsoft and Meta. Vistra has a smaller 6.4 GW nuclear portfolio but has secured substantial long-term contracts with Meta and AWS. While Constellation deserves a premium valuation, Vistra offers a stronger risk-reward proposition at 14.4x forward earnings compared to Constellation's 22.4x, combined with aggressive share buybacks and additional growth catalysts.
