August 2026 update: The investor picture has shifted materially since this article was first published. Bloomberg reported on August 17, 2026 that Anthropic's annualized revenue run rate has surpassed $65 billion, up more than 7x from end-of-2025 levels, with some projections putting full-year 2026 revenue at $100 to $120 billion. Against that revenue trajectory, investors are now targeting a $2 trillion IPO valuation, which would make Anthropic's debut the largest IPO in history, surpassing SpaceX's $1.77 trillion offering in June 2026, according to Fortune (August 13, 2026). The October 2026 Nasdaq timeline remains intact, with the public S-1 filing now expected as early as late August 2026 (Yahoo Finance). In a notable commercial milestone, StartupHub.ai data shows Anthropic's enterprise LLM API market share reached 32% in Q2 2026, surpassing OpenAI's 25% for the first time across the companies we track. On August 21, 2026, CNBC reported that Anthropic's IPO filing will explicitly list "AI backlash" as a risk factor in the prospectus, a sign that the company is proactively disclosing regulatory and public-sentiment risk to investors ahead of the listing. Anthropic's COO Brad Lightcap also departed in August 2026. The original article below reflects the July 21 reporting.
