Key Takeaways
- • Enterprise AI spending reached $176.8 billion by September 2026, up 5.4x from $33 billion in 2025, according to Menlo Ventures' 2026: The State of Enterprise AI report.
- • Agents now generate 80% of all tokens on OpenRouter, roughly seven times human-driven usage, with agent token consumption up 37x since February compared with 5x growth in human usage.
- • Frontier labs Anthropic, OpenAI, and Google capture 69% of enterprise AI deployment spending, up from 50% in 2025; Anthropic's share of enterprise LLM API spend rose from 40% to 55%.
- • New budgets funded 55% of incremental enterprise AI spending, while 22% came from existing software budgets, suggesting AI is expanding the software market rather than cannibalizing incumbents.
- • Enterprise AI application spending reached approximately $77 billion, up from $19 billion, with coding ($34 billion) and AI assistants and productivity tools ($25 billion) making up 76% of that total.
Summary
Menlo Ventures released its 2026: The State of Enterprise AI report on November 3, 2026, finding that enterprise AI spending reached $176.8 billion, up 5.4x in a year as autonomous agents changed how businesses use and pay for AI. Tim Tully, Partner at Menlo Ventures, said enterprise spending jumped from $33 billion in 2025 to $177 billion in 2026 and that companies are not pulling back despite Wall Street skepticism about AI returns. Derek Xiao, Principal at Menlo Ventures, said companies budgeted nearly twice their 2025 spending for 2026 but ultimately spent 2.5 times what they had budgeted.
The report found that growth is driven primarily by greater spending among existing adopters rather than new buyers, as the share of enterprises paying for AI rose only modestly from 55% to 65%. Agents now account for 80% of tokens on OpenRouter, a single channel the firm cites as an indicator of broader consumption shifts. Agent token consumption overtook human traffic in February 2026 and has grown 37x since, compared with 5x growth in human-driven usage.
On the competitive landscape, Deedy Das, Partner at Menlo Ventures, said frontier labs capture nearly seven of every ten dollars spent on enterprise AI. Open-source models handle roughly one in five tokens but account for only about one in 25 dollars of model spending. Joff Redfern, Partner at Menlo Ventures, said AI-native companies hold 96% of coding spending, while incumbents lead IT (91%), data science (88%), and HR (68%).
The report also argues AI is expanding the software market rather than replacing it. New budgets funded 55% of incremental spending, and 22% came from existing software budgets, largely retained by incumbents converting licenses to AI offerings such as Microsoft Office to Copilot. The research found little evidence of enterprises replacing core systems such as Salesforce's CRM or Workday's HRIS. Healthcare remains the largest vertical market at $3.7 billion.
The 2026 edition is based on a survey of nearly 400 U.S. enterprise decision-makers overseeing more than $4 billion in AI spending, combined with a bottom-up market analysis. Total market size figures are Menlo Ventures estimates. Menlo Ventures is an investor in Anthropic and OpenRouter, a disclosure the firm made in the release.
