Big Tech cuts marketing budgets and shifts spend to AI as sales ratio drops 5.5 points

On October 31, 2026, TMTPost published an analysis of Alphabet, Meta, and Microsoft that showed how the three hyperscalers are shifting money away from marketing and toward AI infrastructure. The piece is built entirely from the companies' own figures, so it reads as a data-driven budgeting story rather than an announcement from any of the three firms.

In 2019, the three companies generated $358.4B in combined revenue and spent $46.55B on sales and marketing, or 13 cents of every revenue dollar. By 2025, combined revenue had risen to $885.5B while marketing spend reached $66.34B, bringing the ratio down to 7.5 cents per dollar - a 5.5 percentage point decline over six years.

The aggregate numbers, however, mask big differences in how each company moved. Alphabet's ratio dropped from 11.4% to 7.1%, with revenue up 148.9% while marketing spend rose only 55.4%. Meta went from 14.0% to 6.0%, with revenue up 184.3% against marketing growth of just 21.4%. Microsoft, measured on fiscal-year basis, fell from 14.5% to 9.1%, with revenue up 123.9% and marketing spend up 40.9%. Measured on the same basis, Microsoft's ratio for the fiscal year ending in June 2026 stood at 8.1%, still sliding.

The article stresses that lower ratios do not mean lower spending. All three raised marketing budgets over the six years. What changed is how much of each incremental revenue dollar went to promotion - on that dimension the decline was 42.3%.

Meanwhile, capital is flowing into compute, models, and talent. Alphabet's capex hit roughly $91.4B in 2025, up from about $52.5B a year earlier. Meta spent $72.2B on capex in 2025 and guided to $115B to $135B in 2026.

TMTPost concludes that mature products and first-party distribution channels let these companies promote AI products at little marginal cost, so new budget goes to compute, models, and talent. As the piece puts it, when a company can explain growth with models, it no longer needs to explain growth with media budgets.
