Four Companies Took Eighty Cents Of Every AI Dollar

September 3 – September 9, 2026 · Crunchbase · AI-only analysis
AI raised $12.42B this week, nearly three times last week’s $4.87B. Four rounds cleared a billion dollars each — Mistral $3.49B, Crusoe $3.0B, Cognition $2.0B, Fluidstack $1.5B — and together they are 80% of every AI dollar raised. Now take those four out. The rest of the AI market raised $2.43B against $4.87B last week, a 50% drop, and the typical round fell from $15.0M to $9.9M. More money arrived and most companies got less of it.

Analysis 1 · Overview

Of 221 funded companies this week, 71 (32.1%) were AI, taking $12.42B of the $24.01B total (51.7%). The top five took 84.8% of AI dollars, against 54.8% last week — the most concentrated week in months. The median AI round fell to $9.9M from $15.0M, and 36 of the 71 rounds came in under $10M. A handful of enormous cheques at the top, a thinner market underneath.

Every week since October 2025. The axis is compressed above $30B so ordinary weeks stay readable; the March 5 spike is the $112B OpenAI round. This week is the marked point on the right. Full table on the 41-week tracker.
