Anthropic Investors Reassess Valuation Toward $1.5 Trillion Ahead of Planned November IPO
Anthropic is facing a reduced valuation target ahead of its planned public listing in November. Current and prospective investors discussed a valuation of around $1.5 trillion at a San Francisco investor event, down $500 billion from the $2 trillion estimate previously expected. The reassessment comes after disclosures showed sequential revenue growth slowed to 45% in the third quarter, reaching $16.8 billion with adjusted profitability, following a quarter where revenue had more than doubled.
The reset underscores growing caution over the massive capital requirements of AI developers. Anthropic recorded a $42 billion loss in 2025 and has committed to spending at least $518 billion over ten years on cloud and computing infrastructure. Investors are scrutinizing these obligations amid rising competition from OpenAI and Meta Platforms (META), as well as increased corporate adoption of lower-cost open-source models.
Investors will closely monitor reception for Anthropic's share sale in November as an indicator of public market appetite for frontier AI developers. Attention will also focus on whether cloud infrastructure leaders, including Amazon (AMZN), Microsoft (MSFT), and Alphabet (GOOGL), see sustained demand from broader AI token consumption even if developer growth rates balance out.
