Ep 110 – Hyperscaler CapEx is going nuclear

March 3, 2025

This week’s guest

Charles Fitzgerald

Managing Director Platformonomics LLC

The Big Three hyperscalers each hit an all-time high in CapEx spending in 2024, collectively investing almost $200 billion. For this episode, I speak with Charles Fitzgerald, managing director at Platformonomics, whose annual “Follow the CAPEX” report tracks the cloud providers’ spending. He pulls back the curtain on what’s driving investments, how AI and nuclear power are coming into play, and whether telcos have what it takes to sell AI workload capacity at the edge. Listen now to hear:
