Anthropic Reportedly Preparing S-1 Filing Targeting a $2 Trillion IPO Valuation

Anthropic is reportedly preparing to publicly file its IPO prospectus as soon as the end of August 2026, following a confidential S-1 filed with the SEC on June 1. Investors cited by the Wall Street Journal and others are targeting an October 2026 debut at a valuation near $2 trillion — roughly double its last private valuation of $965 billion.

The Revenue Trajectory Behind the Number

Anthropic's annualized revenue was $47 billion in May 2026; investors expect it to reach $100-120 billion by year-end — a doubling-plus in roughly seven months. That trajectory is the actual argument for the valuation jump, not sentiment alone. Expected IPO proceeds exceed $60 billion, which would make it one of the largest tech IPOs ever, potentially rivaling SpaceX's record $75 billion raise earlier in 2026.

What's Confirmed and What Isn't

• Morgan Stanley, Goldman Sachs, and JPMorgan are reported as lead underwriters
• Anthropic has not publicly confirmed an October timeline, a specific valuation target, a ticker, or an exchange — everything beyond the confirmed confidential S-1 filing is investor and reporter speculation, however well-sourced
• The IPO would land amid Anthropic simultaneously securing separate infrastructure financing (see: Broadcom's reported debt package), meaning Anthropic's capital strategy is running on multiple tracks at once, not sequentially
