Bottom line
The sleeper story is nuclear co-location becoming the only viable path for hyperscale AI deployment - Comanche Peak's 1,200 MW for 20 years signals customers prioritizing speed and reliability over cost optimization. The obvious headline is strong guidance raises, but the real story is Vistra's unique position with 7,000 MW of nuclear capacity when competitors are scrambling for any available power. The binding constraint isn't demand (record engagement levels) but execution bandwidth - hence the $50M SG&A investment in people and development. Burke's confidence jump from 'testing monetization' to 'I feel very good about where things stand' on Comanche Peak reveals deals are accelerating. My view changes if they start missing their hedging discipline or if customer contract terms deteriorate.

The 30-second version

  • Co-located nuclear is quietly becoming the ONLY game in town - Comanche Peak PPA signals fundamental shift
  • West Texas premium flipped the script - they're building because location beats scale
  • Hedging discipline creates hidden option value while peers chase spot exposure
