Anthropic Files for Historic $2 Trillion IPO Amid Massive Losses and Safety Warnings

Claude maker Anthropic revealed a striking paradox in its S-1 filing on October 26: explosive revenue growth alongside staggering losses and frank warnings that the AI models it is developing could pose existential risks to humanity. The San Francisco-based AI company, seeking a Nasdaq listing under the ticker ANT with a valuation between $1.5 trillion and $2 trillion, reported first-half 2026 revenue of $16.3 billion—a 1,300% increase from the prior year—yet accumulated a net loss of $80.7 billion in the same period, most of it non-cash charges tied to convertible notes. The company's operating loss, stripping away accounting adjustments, totaled $693 million.
