Bain & Co now puts AI's required annual revenue at $6 trillion by 2031—triple last year's estimate. The math: $1.5T in yearly AI infrastructure spending by 2031, assuming capex equals 25% of industry revenue. Consumer and enterprise AI markets could total $1.2–1.8T, leaving a $4.2T revenue gap that "must come from new sources of economic value." Bain adds that funding the buildout sustainably would require adding roughly 1 percentage point to annual global GDP growth.
