Investors in Anthropic, the AI safety company behind the Claude model family, expect the startup to pursue an initial public offering in October at a valuation of $2 trillion or more - a figure that would make it the largest IPO in history, surpassing the SpaceX (NASDAQ: SPCX) listing from June 2026, according to reporting by Fortune and Qz.com on August 13, 2026.
The $2 trillion figure comes from Anthropic backers, not company executives. Anthropic has not publicly confirmed an October timeline, a valuation target, or any specific exchange or ticker. The company filed a confidential draft registration statement with the Securities and Exchange Commission on June 1, 2026, per Fortune and Yahoo Finance, keeping detailed financials private until it chooses to publish a public prospectus.
A revenue story powering the valuation case
Anthropic disclosed in May 2026 that its annualized revenue had crossed $47 billion. Institutional investors participating in the company's Series H expect that figure to reach $100 billion to $120 billion by year-end, representing growth of more than 800% year-over-year, per Fortune. The Wall Street Journal has reported that Anthropic expects a 130% revenue surge to bring it to its first operating profit.
One investor told Fortune that at a 30-times-revenue multiple - conservative by the standards of high-growth AI infrastructure companies - Anthropic's implied valuation would exceed $3 trillion. The $2 trillion target represents a discount to that revenue-based comp.
If the IPO proceeds at $2 trillion, it would eclipse the SpaceX debut: SpaceX priced at $135 per share on June 12, 2026, raising approximately $75 billion at a valuation near $1.8 trillion. SPCX currently trades around $140, implying a market cap of roughly $1.84 trillion.
