Anthropic Prepares to File for Largest IPO on Record, Targeting $2 Trillion Valuation

Anthropic is moving toward a landmark initial public offering that could surpass SpaceX's record-breaking 2026 debut, with the company widely expected to file publicly as soon as late October and proceed to a November listing at a $2 trillion valuation. The AI safety company, which confidentially submitted its draft S-1 registration to the SEC in June, has been navigating the regulatory review process while preparing investor roadshows. Market analysts estimate that following an IPO at approximately $1.8 trillion, Anthropic's post-trading market capitalization could reach $2.4 trillion—exceeding SpaceX's current $2.1 trillion market cap set after that company's $75 billion June debut.
