Anthropic targets October IPO at $965B valuation as investor roadshow begins

Anthropic is preparing to go public as early as October 2026, with Goldman Sachs, Morgan Stanley, and JPMorgan Chase coordinating investor meetings for the Claude AI maker's anticipated debut at a $965 billion valuation, Bloomberg reported on July 15. If the listing proceeds on schedule, it would be the first major AI lab to reach public markets and overtake rival OpenAI in the race to go public.

The Path to Market

Anthropic confidentially filed a draft S-1 prospectus with the US Securities and Exchange Commission on June 1, 2026 — a standard step that allows a company to work through regulatory comments before committing to a public date. The company selected its three lead underwriters — Goldman Sachs, Morgan Stanley, and JPMorgan, the three largest US investment banks by revenue — two days later.

The investor meetings being organized now are a roadshow rehearsal, in which bank analysts introduce the company to institutional investors before a formal pricing process begins. Final timing depends on SEC review progress and market conditions.

Valuation and Context

Anthropic's $965 billion valuation stems from a $65 billion funding round closed in May 2026, which pushed it above OpenAI's $852 billion private valuation for the first time. The round included investments from Google, Amazon, Spark Capital, and others who have backed Anthropic since its 2021 founding.

A successful listing would represent one of the largest tech IPOs in history. For reference, SpaceX raised $86 billion in its June 2026 IPO — a record at the time — before its shares fell below the $135 IPO price in mid-July. Anthropic's target valuation near $1 trillion places it in a category alongside only a handful of public companies globally.

Why This Matters for AI

Going public before OpenAI would give Anthropic a significant strategic advantage: access to public markets for fundraising, a public currency for acquisitions, and a credibility signal for enterprise customers making multi-year AI procurement decisions. Enterprise contracts increasingly ask whether a vendor is financially stable enough to be around in five years.

Anthropic's flagship Claude Sonnet 5 model, released in July 2026, has gained traction in agentic coding and enterprise deployments. The company generated strong revenue growth in early 2026, though exact figures have not been disclosed. An S-1 filing, once made public, will reveal revenue, growth rates, burn rate, and major customer concentration for the first time.

What Could Delay It

A volatile market or SEC questions about Anthropic's unusual revenue recognition structure — the company receives large upfront cloud compute credits from Amazon and Google alongside cash — could push the timeline past October. OpenAI has also filed confidentially and could accelerate its own listing if Anthropic's roadshow generates strong demand.
