Microsoft, Alphabet, Amazon to spend ~$600B on AI infrastructure in 2026

Peter Diamandis highlights a projection that Microsoft, Alphabet and Amazon will collectively spend roughly $600 billion on AI infrastructure capex in 2026. For scale: the US Interstate Highway System — 48,000 miles of road across 48 states — took 65 years to build and cost about $128 billion in today's dollars, meaning one year of Big Tech AI capex is nearly 5x that landmark project.
