Anthropic’s IPO valuation of $965 billion and its confidential SEC filing make it one of the largest public offerings in US stock market history.
The Claude maker’s IPO filing comes after its revenue grew 30-fold in 16 months, from $1 billion to $30 billion in annualized run rate.
Anthropic IPO Filing: What the SEC Submission Means
Anthropic confidentially filed its S-1 IPO prospectus with the SEC on June 1, 2026, starting the formal process toward a public listing.
A confidential filing lets Anthropic finalize its financials privately before publicly revealing full details to retail investors and analysts.
Per Fortune reporting, Goldman Sachs, JPMorgan, and Morgan Stanley are leading an offering expected to raise more than $60 billion.
The targeted listing date is October 2026 on the Nasdaq, pending SEC review and market conditions remaining favorable for large tech offerings.
Anthropic’s IPO will be the first pure AI safety company ever to trade on a public stock exchange, a landmark in the AI industry.
Anthropic Valuation: How Did It Reach $965 Billion?
Anthropic’s $965 billion valuation comes from its May 2026 Series H-1 funding round, which eclipsed OpenAI’s valuation for the first time.
Amazon and Google are the two largest strategic investors in Anthropic, having collectively committed over $15 billion in cloud partnership deals.
The valuation reflects Anthropic’s position as the leading safety-focused AI lab and creator of the Claude model family used by millions.

At $965 billion, Anthropic would enter the public markets as one of the 10 most valuable companies ever listed in the United States.
Anthropic Revenue: $1 Billion to $30 Billion in 16 Months
Anthropic’s annualized revenue reached $30 billion by April 2026, up from just $1 billion at the end of 2024, a 30x increase in 16 months.
The primary revenue driver is Claude Pro, Max, and Team subscriptions combined with rapid enterprise adoption of the Claude API.
Anthropic has over 500 enterprise customers spending more than $1 million per year each, a critical metric for institutional investors.
Gross margins stand at approximately 40% today, with Anthropic projecting margins of 77% by 2028 as compute costs fall and scale grows.
The company is not yet profitable and expects to reach profitability in 2028, a timeline common for high-growth AI infrastructure companies.
How the Anthropic IPO Compares to OpenAI and Google DeepMind
OpenAI has not filed for an IPO as of mid-2026, making Anthropic the first major frontier AI lab to pursue a public listing.
Google DeepMind operates as a subsidiary of Alphabet, which is already public, so it will not have its own separate listing.
The talent flow from DeepMind to Anthropic in 2026 reflects investor confidence in Anthropic’s independent path to market.
SpaceX’s record-breaking IPO earlier in June 2026 has raised appetite on Wall Street for large technology listings in the second half.
Per CNBC coverage, the Anthropic IPO is expected to be among the largest tech offerings in Nasdaq history.
What the Anthropic IPO Means for Claude Users and Developers
Going public brings new financial scrutiny but also capital that Anthropic plans to use for compute expansion and model development.
As a public company, Anthropic will face quarterly earnings pressure that could influence pricing decisions on Claude Pro and API plans.
Developers building on the Claude API should expect continued investment in model capabilities but potentially less flexibility on long-term pricing.

The IPO will also require Anthropic to publish detailed financials, giving developers and users unprecedented transparency into the company’s operations.
