The big questions its S-1 leaves unanswered
Key Points:
- Anthropic's S-1 filing reveals the AI lab generated $16.29 billion in revenue with an 85% gross margin in the first half of 2026, but its rapid revenue growth slowed significantly in the third quarter.
- The company’s costs are heavily driven by compute and infrastructure, and investors lack clarity on how much compute is allocated to training new models versus serving customers, which affects future margins.
- Anthropic’s unique public benefit corporation structure grants CEO Dario Amodei and six co-founders special voting power controlling 50.1% of total votes, raising questions about investor control and its impact on share price.
- The AI lab is targeting a potential IPO valuation between $1 trillion and $2 trillion, which could significantly influence the AI sector’s market sentiment depending on where within that range the valuation falls.
- Anthropic holds an unprecedented amount of cash for a company going public, positioning it with more liquidity than nearly any other U.S. company at IPO.
