Will artificial intelligence investments ever generate enough revenue to pay for themselves?
Core argument: Five tech giants project $700bn in capital spending for 2026 alone, driving infrastructure demand that results in 40% growth for.
Alphabet, Microsoft, Amazon, Meta and Oracle [are] projecting $700bn in capital spending in 2026 alone. Questions are being raised over whether the wave of investment can last — particularly if demand from the relatively small number of companies driving the build-out slows. Bain & Company has estimated that the tech industry must generate $2tn in AI revenue per year to justify current data centre spending trends. Schneider Electric told the FT AI data centres were a “core growth driver” for the company, while Siemens’ head of data centres Ciaran Flanagan said AI demand was a “long-term, structural growth trend rather than a short-term cycle,” adding that its data centre business grew 40% in 2025.
