Will artificial intelligence infrastructure spending finally match its economic returns?
Core argument: The Big Seven’s 2026 capex guidance of $863 billion exceeds their combined operating cash flow for the first time, with roughly $282 billion—one-third of total spend—financed through debt, equity, and leases rather than internal cash generation.
In 2024, cash funded 85% of Alphabet, Amazon, CoreWeave, Meta, Microsoft, Nebius, and Oracle's (the Big Seven's) capex; it dropped to 70% in 2025 and is at two-thirds in 2026. Capex guidance of $863 billion for 2026 exceeds the Big Seven’s combined operating cash flow for the first time. Some $282 billion – around a third – is funded by debt, equity, and leases. Current capex reading is great news for anyone buying compute. A third of the buildout is about to come online – and its owners will be looking to earn with it.
