Enterprise AI deployment spend hit $177B. Coding apps alone are $34B.

Menlo Ventures published its fourth annual State of Enterprise AI report on November 3, 2026. The headline number: enterprise AI deployment spending reached $176.8 billion by September 2026 — often rounded to $177B — up 5.4x from $33B in 2025. Growth accelerated versus last year's 3.9x. These are Menlo estimates (survey + bottoms-up model + filings), not audited company totals.

Where the money goes. Of that deployment stack, Menlo splits roughly $99.5B infrastructure and $77.3B applications. Inside apps, two categories dominate 76% of spend: coding at $34.0B (up 7.7x) and enterprise chatbots / workplace assistants at $25.0B. Healthcare is a distant third at $3.7B. For builders, the punchline is blunt: coding is the biggest AI app category, and Menlo says AI-native providers capture 96% of that coding spend (including lab products like Claude Code and Codex, which together are about $24B / 70% of coding).

Who wins the API bill. Frontier labs (Anthropic, OpenAI, Google) command 69% of deployment dollars, up from 50%. On enterprise LLM API spend specifically, Anthropic rose from 40% to 55%, OpenAI from 27% to 31%, and Google fell from 21% to 9%. Open-source is 19% of usage but only 4% of spend.

Agents — with a caveat. Menlo's agent story leans on OpenRouter data: agents now generate 80% of OpenRouter tokens (~7x human-driven), and agent traffic is up 37x since overtaking humans in February. Menlo itself notes OpenRouter skews toward developers and startups more than the enterprise buyers in its survey — so treat that as a usage channel signal, not a census of every corporate seat.

How they got the numbers. Nearly 400 U.S. enterprise decision-makers overseeing more than $4B in AI spend, fielded by Morning Consult (Sept 8–26, 2026), plus Menlo's market model. Average reported spend hit 4.7x last year versus a planned 1.9x. Menlo also says 55% of incremental AI dollars came from net-new budgets rather than ripping out Salesforce or Workday.

Catch. Menlo is a venture firm with portfolio companies across this stack (including Anthropic, OpenRouter, and several infra/app names it flags with asterisks). The $177B figure is their estimate of annualized run-rate deployment spend. MODEL has not tested any product named in the report. Not sponsored. Not investment advice.
