mmurph · x · 2026-11-06

Menlo Ventures' 2026 State of Enterprise AI report shows deployment spend surged from $33B to $177B in a year (5.4x growth vs 3.9x prior), with every model-development dollar generating $1.70 in revenue.

Agent traffic on OpenRouter is up 37x since overtaking human traffic in February, tying spend to work performed.
Frontier labs command 69% of deployment dollars; Anthropic's enterprise API share rose from 40% to 55%, OpenAI's from 27% to 31%, while Google's fell from 21% to 9%. Open-source holds 19% of usage but only 4% of spend.
Coding ($34.0B) and chatbots ($25.0B) make up 76% of the $77.3B app market; coding is 96% AI-native, while incumbents gain share in IT, data science, and HR.
55% of AI dollars are net new spend, expanding the software economy rather than cannibalizing it.
