The Anthropic IPO is shaping up to be one of the biggest stock market stories of late 2026. The firm that makes Claude has scaled up its revenues from $1 billion to around $47 billion in less than a year-and-a-half and just beaten OpenAI to the doors of the SEC. This is what we know for sure, what is just a hunch, and what you really need to know about Anthropic IPO 2026.
Anthropic IPO 2026: What Actually Happened
Anthropic filed its draft registration statement on Form S-1 confidentially with the U.S. Securities and Exchange Commission on June 1, 2026, thus officially marking the start of its journey to becoming a publicly-listed company. It was only the first big AI-safety lab to file the S-1 form as opposed to rival company, OpenAI, which filed on June 8, 2026.
Because the filing is confidential, the full S-1 isn't public yet. That means exact revenue breakdowns, customer concentration figures, and detailed financials are still shielded from competitors and the public until Anthropic chooses to release its public prospectus, which typically happens at least 15 days before the investor roadshow begins.
How We Got Here
Anthropic was formed in 2021 by brothers Dario and Daniela Amodei and some other researchers who quit from OpenAI because of differing views on the direction and priorities of the company’s work. The lab which focused mainly on safety turned into an unparalleled success story in the history of enterprise software growth – from roughly $1 billion annual revenue in the end of 2024 to about $47 billion in May 2026, i.e., in less than one and a half years.
Anthropic IPO Date: When Will It Actually List?
The most honest answer is that the Anthropic IPO date isn't locked in yet. What's known is the target: Anthropic is aiming for an October 2026 listing on the Nasdaq, based on reporting from multiple outlets tracking the underwriting process. The expected sequence looks roughly like this:
The submission of a confidential filing does not mean that the company is bound to any particular deadline; it only means that Anthropic has an opportunity to go public after the completion of the SEC review process. And the company has stated that "the offer will depend on market conditions and other factors.
Anthropic IPO Valuation: Why $965 Billion (and Maybe More)
Anthropic's most recent private valuation stands at $965 billion, set during a $65 billion Series H-1 funding round that closed in late May 2026, just days before the IPO filing. That figure already pushed Anthropic ahead of OpenAI, which was valued at $852 billion in a round earlier in the year.
Many investment bankers believe it is now the base case that Anthropic will cross the $1-trillion mark when it lists, given favorable market conditions and continued growth. "This is just the tip of the spear for the overall AI investment wave cycle," said Dan Ives of Wedbush Securities.
The Growth Behind the Number
The Risks Behind the Anthropic IPO News
Alongside the excitement, there's real Anthropic IPO news worth treating with caution. However, the firm is still unprofitable, with an estimated loss of around $11 billion expected in 2026 and again in 2027 despite generating revenues worth billions. This translates to a loss margin of around 23%.
That last point matters if you've seen "pre-IPO Anthropic shares" advertised anywhere. As of now, there is no tradable Anthropic stock. Any product claiming otherwise outside of an officially sanctioned channel deserves serious scrutiny.

How does the Anthropic IPO compare to OpenAI's?
Anthropic filed its confidential S-1 first, on June 1, 2026, with OpenAI following about a week later. Anthropic's reported $965 billion valuation currently sits above OpenAI's $852 billion figure, and Anthropic's revenue has grown roughly 10x annually compared to OpenAI's reported 3.4x — though the two companies report revenue using different accounting methods, which complicates a direct comparison.
