Anthropic's S-1 Reveals $16.3B Revenue, 900% NRR, and $80.7B Paper Loss

Anthropic filed its Form S-1 on October 26, 2026, revealing $16.3 billion in first-half revenue, a ~900% net revenue retention rate, and an $80.7 billion net loss largely driven by non-cash accounting charges tied to its rising valuation. The filing shows revenue grew 14x year-over-year, with adjusted operating income turning positive at $1.6 billion. The loss stems from a $72.4 billion fair-value charge on convertible notes, while operating losses were only $693 million. The company plans to list on Nasdaq under "ANT" with a reported valuation target of $1.5-$2 trillion. Anthropic holds $131.7 billion in cash but has committed hundreds of billions to compute through 2045. A novel governance structure gives co-founders 50.1% voting control via Class F stock, while a trust elects the board majority. The IPO is expected in late November.
