Menlo Ventures has released a report indicating that enterprise spending on AI has significantly surpassed expectations, driven largely by a subset of heavy users. The report states that AI deployment spending reached $176.8 billion by September 2026, a substantial increase from $33 billion in 2025. This represents a 4.7-fold increase, compared to the planned 1.9-fold increase. The acceleration is attributed to the widespread use of AI agents, particularly on platforms like OpenRouter, where agents account for 80% of the generated tokens.

Key Takeaways

• Menlo Ventures’ findings suggest a significant underestimation of enterprise AI spending, with a 4.7-fold increase observed.
• The report highlights that a small group of heavy users is responsible for the majority of the spending increase, indicating concentrated adoption.
• AI agents are a key driver of the spending surge, accounting for the majority of token generation on platforms like OpenRouter.

What to Watch

Market participants will be closely monitoring Anthropic’s valuation as the year-end approaches, particularly given the increased enterprise spending on AI. Developments such as new funding rounds or strategic partnerships could influence Anthropic’s valuation prospects. Observers are likely to focus on announcements from key actors like Dario Amodei and strategic partners such as Amazon and Google, which could provide further indication of future valuation trends.
