The AI arms race is eating into Big Tech's cash flow: Chart of the Day

Big Tech’s AI build-out is consuming a larger share of operating cash flow as companies pour money into data centers, chips and other infrastructure. Amazon is spending nearly all of its operating cash flow on capital expenditures, while Alphabet and Meta are close behind; Microsoft is lower but increasing capex. That rising capex is squeezing free cash flow and lifting valuation multiples — Alphabet’s forward price-to-free-cash-flow has surged above 200x — turning the AI trade into a cash-flow test. Investors face a trade-off between funding growth and waiting for cash returns, raising scrutiny on how long markets will tolerate stretched cash generation before AI spending produces clear payoffs.
