Anthropic Files Final SEC IPO Papers, Targeting Up To $2 Trillion Valuation
On Monday, October 26, 2026, Anthropic filed a public Form S-1 with the Securities and Exchange Commission to launch an IPO under the ticker ANT.[1] Reports say the offering could value Anthropic between $1.5 trillion and $2 trillion, potentially making it one of the largest initial public offerings in history.[1]
The S-1 does not yet specify how many shares will be sold or the price range, and the filing says the offering could occur as soon as November 2026.[1] Reports compare the prospective valuation to SpaceX, which was valued near $1.8 trillion when it listed in June 2026.[1] CBS News framed the filing as part of a broader race for AI dominance and highlighted Anthropic's emphasis on safety.[2]
NPR noted the filing comes during a period of volatility for AI-related stocks, citing moves in shares of CoreWeave, Intel, Meta and Nvidia.[1] Those market swings could influence how aggressively Anthropic and its underwriters set price and timing if the deal proceeds.
Investors and regulators will watch the S-1 closely as the company transitions from private funding to public markets.
