Breaking News》Anthropic「Secretly Submits S-1」Launches IPO! Valuation Approaches One Trillion Dollars to Compete with OpenAI

The Wave of AI Giants Going Public Has Arrived!
Anthropic, the AI startup famous worldwide for the Claude model, shockingly announced today (June 1) that it has submitted a confidential draft S-1 registration statement to the U.S. Securities and Exchange Commission (SEC), paving the way for an IPO.
Just days ago, the company completed a $65 billion funding round at an astonishing valuation close to $1 trillion.
As OpenAI and SpaceX also initiate their IPO processes one after another, the second half of 2026 is destined to see an unprecedented frenzy of tech stock IPOs.
(Background recap: Michael Burry of "The Big Short" criticizes SpaceX for not supporting a trillion-dollar valuation and harshly calls out Anthropic's compute frenzy as an illusion)

• Just completed $65 billion funding, valuation skyrockets to $965 billion
• An epic "AI and tech stock IPO frenzy" in 2026
• Why go public now?

The capital arms race in the global AI industry has officially spread from the private equity market to the halls of Wall Street in the public market.

This startup giant, known for developing one of the world's strongest AI models "Claude," has officially filed a confidential draft S-1 with the SEC, initiating the standard process for an initial public offering (IPO).

Just completed $65 billion funding, valuation skyrockets to $965 billion

Anthropic’s move to Wall Street is backed by strong confidence. Just at the end of May, the company completed a Series H funding round worth a staggering $65 billion.

This epic financing pushed Anthropic’s valuation to an astonishing $965 billion (approaching the $1 trillion mark), far surpassing the $380 billion valuation in February this year. The backers include top-tier institutions like Altimeter, Sequoia Capital, and cloud computing giants like Amazon (Hyperscaler).

In terms of financial performance, Anthropic has already demonstrated a strong ability to generate revenue:

• Profit milestone: Achieved operational profit in Q1 2026.
• Revenue explosion: With the excellent performance of the new Claude Opus and significant growth in enterprise clients, Q2 revenue is projected to reach $10.9 billion.

An epic "AI and tech stock IPO frenzy" in 2026

Anthropic’s big move perfectly completes the most critical piece of the puzzle for the global tech giant IPO wave in 2026. Currently, the three most anticipated unlisted giants are all fully on the IPO track:

| Tech Giants |
| --- | --- | --- |
| IPO Latest Progress & Status | Estimated Listing Timeline |
| --- | --- | --- |
| SpaceX | Public S-1 filing, valuation at $1.8 trillion | June 2026 |
| OpenAI | Confidential submission of S-1 draft at the end of May | Market expects Q4 2026 |
| Anthropic | Announced today "confidential submission" of S-1 draft | Market expects Q4 2026 |

Why go public now?

Market analysis indicates that both Anthropic and OpenAI have chosen to initiate their IPO processes at this time mainly to cope with the "astronomical" computational and infrastructure costs required to train the next generation of artificial general intelligence (AGI).

By heading to the public market, Anthropic can not only raise massive capital to ensure it stays competitive in the compute arms race but also provide early investors and employees with liquidity during the peak of the AI boom. Since it is currently in the confidential submission stage, the SEC will conduct a non-public review. Once approved and the company decides to proceed with the offering, the detailed financial data of this near-trillion-dollar giant will be made public.
