Deirdre Bosa argues that Big Tech is becoming the new utilities as Alphabet, Microsoft, Meta, and Amazon build an AI intelligence grid that customers will rent rather than build. She says this utility-like shift changes valuation, with multiple compression, capex crowding out buybacks, a focus shift to ROIC, and closer regulatory scrutiny. She also warns that the current cloud/AI buildout differs from the prior cycle because hyperscalers and Meta are spending ahead of demand rather than serving already-paying customers.
