Investors warn Anthropic could struggle to sustain revenues post-IPO

Investors and analysts told the FT that Anthropic's planned 2027 IPO faces a revenue sustainability problem. Its annualized revenue is about $5 billion, with over 70% coming from fewer than 10 large clients. API revenue has low switching costs, so if rival models catch up on performance, big customers can renegotiate or leave. The article does not disclose a specific IPO valuation target, but notes this revenue concentration will make public-market investors cautious.

Why it matters: FT exclusive: investors publicly question Anthropic's revenue concentration pre-IPO — over 70% of ~$5B annualized from fewer than 10 clients. Solid info, but the article doesn't disclose the IPO valuation target, so capped at 78.
