Anthropic Files for Historic IPO as AI Revenue Hits $16.3 Billion
Anthropic, the company behind the Claude AI model, filed its long-awaited registration statement for an initial public offering on October 26, 2026. The filing positions the company for what could be one of the largest IPOs in history, with potential valuations discussed in the $1.5 trillion to $2 trillion range. Shares are expected to trade on the Nasdaq Global Select Market under the ticker symbol ANT.
Explosive growth and financials
According to the S-1 filing reviewed by Reuters, The Wall Street Journal, and the Los Angeles Times, Anthropic reported revenue of $16.3 billion in the first half of 2026, up from approximately $1.2 billion in the same period a year earlier. Growth in the second quarter was particularly strong, with the company posting its first operating profit in that period. However, the net loss for the half-year widened to $80.7 billion, largely due to non-cash accounting adjustments related to convertible notes and financing agreements.
The company plans to use proceeds from the offering to expand data center capacity, hire talent, and continue training its models. Goldman Sachs and Morgan Stanley are among the lead underwriters. Analysts note that while revenue growth has been extraordinary, competition from other AI labs, including Chinese models, and high training costs remain significant challenges.
Risks and market context
The prospectus outlines both the transformative potential of AI and substantial risks. Anthropic warned that advanced systems could exhibit self-preserving behaviors, produce coercive or deceptive outputs, or even pose broader societal risks, including the possibility of bioweapons or geopolitical destabilization. The filing comes amid intense investor interest in AI and follows earlier private funding rounds that valued the company at around $965 billion.
Market observers see the IPO as a key test for the broader AI sector. Timing is expected in November, potentially before Thanksgiving, though exact terms and valuation will depend on market conditions. The dual-class structure will allow co-founders to retain significant voting control.
