Anthropic Files for US IPO as AI Rivalry Heats Up

Anthropic filed its US IPO application on Monday, seeking new capital for its AI model Claude. The listing could occur in November under ticker ANT on the Nasdaq. The prospectus shows strong growth since 2025, with first-half 2026 revenue of $13.6 billion, fourteen times the prior-year period. However, investors increasingly doubt high AI valuations, and estimates of Anthropic's worth range from $1.5 trillion to $2 trillion. Anthropic posted a nearly $81 billion first-half loss, mostly accounting-related from convertible bonds, with an operating loss of $693 million. Founders will retain voting control via preferred shares despite holding only 10 percent after the IPO.
