How much of the AI data centre buildout needs outside financing?
Core argument: Google, Amazon, Microsoft and Meta will spend more than $400bn on data centres in 2026, on top of more than $350bn this year, as generative AI's computing demands shift hyperscalers away from the self-funded model that historically covered such spending.
Google, Amazon, Microsoft and Meta will spend more than $400bn on data centres in 2026 — on top of more than $350bn this year. Historically, most of the spending by the “hyperscalers” — Amazon Web Services, Microsoft Azure and Google Cloud — building data centres for their cloud services businesses was self-funded. But the scale of computing power needed for generative AI is changing that. While internal cash flows largely covered costs of up to $200bn last year, costs are projected to double this year and increase further next. Hyperscalers’ generative AI revenues were just $45bn last year, according to Morgan Stanley analysts — although they predicted revenues would exceed $1tn by 2028. Between now and 2029, however, global spending on data centres will hit almost $3tn, according to Morgan Stanley analysts. Of that, just $1.4tn is forecast to come from capital expenditure by Big Tech groups, leaving a mammoth $1.5tn of financing required from investors and developers.
