As seen on the 24/7 Wall St. homepage on November 1, 2026.
Four of the market's largest cash machines now spend $201.9 billion a quarter on AI buildout, so the free cash flow that funded buybacks and dividends is the line to watch next earnings season.

Free cash flow is the pool that funds buybacks and dividends, and when CapEx grows at this pace, that pool shrinks at the market's largest cash generators, so the effect is not marginal.
Watch free cash flow conversion next earnings season: how much of operating cash flow survives after the AI buildout bills are paid. A further acceleration in CapEx without a matching rise in revenue would compress that conversion rate and pressure capital return programs.
