Will major AI companies successfully launch IPOs by the end of 2026?

Anthropic is preparing for an initial public offering in November 2026 after confidentially filing for the event on June 1, 2026. This move follows a significant increase in the company's revenue run rate, which reached $65 billion by July 2026.

Why it matters

The company’s rapid financial growth has facilitated plans for a public market debut that could potentially value the firm at $2 trillion. The scale of this offering underscores the massive capital intensity currently driving the leading edge of foundational model development.

Anthropic reached a $65 billion revenue run rate as of July 2026, a substantial increase from its $9 billion rate at the end of 2025. Projections suggest a potential IPO valuation of $2 trillion with a goal of raising $100 billion.

The players

Anthropic

An AI research and deployment company focused on building large-scale foundational models with an emphasis on safety and steerability.

OpenAI

A developer of generative AI models including the GPT series and a major competitor in the large language model space.

Sam Altman

The details

Anthropic has completed a confidential IPO filing, a regulatory process that allows companies to submit financial records to the U.S. Securities and Exchange Commission while keeping details private until closer to the public launch. The company is currently finalizing third-quarter financial results to support the upcoming market entry. While OpenAI also submitted a confidential IPO filing on June 8, 2026, CEO Sam Altman stated on September 11, 2026, that the firm will not hold an IPO this year.

The Tech Race

This move signals a major shift as leading AI companies move from private funding toward public market capitalization. While both Anthropic and OpenAI have filed confidentially, the divergent timelines between these competitors demonstrate different approaches to managing massive growth and transparency.

The IPO process will make Anthropic’s financial performance and operational details transparent to public investors and the wider technology community for the first time. Market participants should monitor the November 2026 timeline for official updates regarding share availability and public disclosures.

The takeaway

Anthropic’s push toward an IPO in November 2026 marks a significant milestone in the AI sector's transition to public market maturity. Investors and industry observers should monitor the upcoming third-quarter financial results for the latest indicators on the company's valuation trajectory.
