Five US tech giants outspend their own cash flow on AI infrastructure

The five American technology groups at the centre of the AI buildout — Microsoft, Alphabet, Amazon, Meta and Oracle — invested more than their operations generated in cash during the first nine months of 2026, the first such gap in a data series beginning in 2011, according to a Reuters analysis. The money is going into data centres, servers and computing gear for artificial intelligence, and the shortfall means the buildout is now financed partly from outside capital rather than from the advertising, software and retail businesses that fund it.

The arithmetic is stark. Operating cash flow across the five rose 29 per cent to $542.9bn while capital expenditure almost doubled to $556.9bn, turning a free cash flow surplus of $143.5bn a year earlier into an aggregate deficit of $14bn. The share of operating cash returned to shareholders through dividends and buybacks fell from 27.4 per cent to 9.3 per cent, the lowest in the 15-year series; buybacks dropped 83 per cent and neither Meta nor Alphabet repurchased shares in the nine months. Depreciation is following the spending: Meta's charge for servers and networking equipment rose from $9.34bn to $14.34bn, and it carries $89.5bn of assets under construction. Economists cited by Reuters said concern is growing over both the scale of the sums and how they are financed, though recourse to external funding does not by itself indicate distress, since terms vary widely between companies.

In the latest reporting round, only Microsoft remained free-cash-flow positive in the quarter among the four hyperscalers covered by CNBC, at $18.63bn, itself a 27 per cent decline; Meta posted negative free cash flow of $2.12bn and Alphabet $9.07bn for the quarter, while Amazon's free cash flow over the twelve months to September was negative $42.4bn, against positive $14.8bn a year earlier. Microsoft raised $25bn in the bond market on Thursday against roughly $115bn of demand, Bloomberg reported, its 2066 bond priced at 1.05 percentage points over US Treasuries, against about 1.33 points at which Alphabet's 40-year debt traded — not identical transactions, and the Alphabet figure a trading rather than a new-issue spread. S&P Global Ratings cut its outlook on Meta from stable to negative on Friday while affirming its AA- rating, projecting a $71bn free cash flow deficit in 2027 and expecting the 2028 deficit to be funded entirely with debt; Meta disputes that assessment. Meta plans to raise up to $97.5bn — $25bn in common stock, $12.5bn in convertible preferred carrying a 6.5 per cent cumulative dividend and up to $60bn from future non-voting share sales — with Nvidia and AMD investing $3bn and $1bn respectively.

Strain is visible in the legacy businesses. AWS revenue grew 39 per cent in the third quarter, but Amazon's online sales rose 2 per cent against 10 per cent a year earlier, and the midpoint of its revenue guidance fell below the $244.5bn analysts expected. Alphabet's core search business slowed for a third consecutive quarter and YouTube advertising came in light. Mark Mahaney of Evercore called cloud revenue “good news” and the decelerating advertising business “the overwhelming bad news”; Forrester's Tracy Woo said Alphabet's capex had been “tolerated for now” but that it “is walking a fine line”. On Friday the Nasdaq fell 2.86 per cent and the S&P 500 1.82 per cent, with Intel down almost 30 per cent.

The unresolved question, which S&P cites as uncertain and Meta contests, is when the investment produces revenue exceeding its cost. Microsoft has said it will return to the bond market as it ramps AI infrastructure spending, and rising interest rates are making debt costlier for the cash-burning neoclouds on which the global buildout depends.
