Capex growth plateaus under cash constraints
Free cash flow approaching zero removes the capacity for continued aggressive capex escalation. Speculative optionality in AI stocks rests on capex continuing to rise, so when hyperscalers hit physical cash constraints, capex growth must plateau or reverse, with aggregate 2027 guidance implying under 15% growth over 2026 actuals.

Capex growth stays at or above 15% as funding keeps pace
Usage deepens the ecosystem and makes the leader harder to displace, and because marginal serving cost is small once models exist, none of the majors can afford to be the one that waits, so spending stays aggressive. Executives who understand that failing to cannibalize their own business invites disruption keep spending heavily on AI infrastructure regardless of near-term earnings optics. Firms that can fund this growth internally rather than depending on external capital markets gain an extended runway that keeps the buildout pace intact. On this view aggregate 2027 capex guidance from Alphabet, Amazon, Microsoft and Meta implies year-over-year growth of 15% or more.
