  • Alphabet lifted 2025 capex guidance to $91 billion–$93 billion as Google Cloud revenue climbed 34% to $15.16 billion and the backlog expanded to $155 billion.
  • Reuters reported Amazon projects $125 billion in 2025 capital spending and noted Nvidia’s valuation topped $5 trillion as analysts estimate AI infrastructure outlays could reach $3–$4 trillion by 2030.
