Artificial intelligence company Anthropic has taken a major step toward going public, filing a confidential draft registration statement with the U.S. Securities and Exchange Commission on June 1, 2026. The Form S-1, submitted under procedures that keep financial details private for now, targets a valuation of $965 billion for the stock offering.
What the confidential filing means
The SEC's confidential review process allows late-stage companies to prepare their public debut without immediately revealing sensitive information to competitors or the market. By filing under these rules, Anthropic can work through any SEC questions or revisions before making its prospectus public — a standard move for big IPOs. The filing confirms that the company, known for its Claude model family and safety-focused approach, is serious about listing shares on a U.S. exchange.
A $965 billion target — and what it signals
The reported valuation target of $965 billion would place Anthropic among the most valuable companies to ever hit the public markets. For context, that figure dwarfs the market caps of many established tech giants. The number reflects investor appetite for AI — a sector that's drawn enormous capital in recent years. But the confidential filing means outsiders can't yet see the revenue, profit, or user numbers that back that valuation. Those details will emerge once the S-1 becomes public.
What comes next
Anthropic hasn't said when its IPO roadshow might begin or on which exchange it plans to list. The confidential review process typically takes several weeks or months, and the company can choose to wait until market conditions are favorable. What's clear: the paperwork is in motion. The next milestone will be a public filing — an amended S-1 that lays out financials, use of proceeds, and risk factors for potential investors. Until then, the $965 billion figure remains an ambition on paper, not a lock.
