Report: Anthropic May File IPO Application as Early as Friday Sanyan Finance Download the App for Exclusive Early Access October 22, 2026, 10:00:40 From Hubei Updated October 22, 2026, 10:26:39
October 22 news, according to Yahoo Finance, three people familiar with the matter said that AI company Anthropic will publicly submit its S-1 investor prospectus as early as this Friday. The move will be a key step for the company and is expected to become the largest IPO in history.
The highly anticipated IPO is expected to surpass SpaceX's (SPCX) June IPO and is widely seen as a key test of investors' interest in the AI boom, as investors grow increasingly concerned about the industry's massive spending.
Anthropic confidentially submitted a draft IPO registration statement to the U.S. Securities and Exchange Commission (SEC) in June. Under SEC rules, companies using the confidential process must make their registration materials public 15 calendar days before the formal investor roadshow begins.
Anthropic did not respond to a request for comment on the timing of its S-1 filing.
The public filing will clear a key procedural hurdle for a November listing, but the exact timing will still depend on market conditions and other factors. Crucially, it will also give ordinary investors their first look at the financial details and risks of one of the fastest-growing companies in the AI industry.
Anthropic is spending billions of dollars on AI infrastructure to train and run its Claude model suite. This includes partnerships with Google (GOOG, GOOGL) and Amazon (AMZN), as well as renting graphics processing unit (GPU) capacity from SpaceX's Colossus 1 data center.
According to The Wall Street Journal on Tuesday, the company's revenue in the first half of 2026 was $16.3 billion, with a net loss of more than $80 billion. Reuters previously reported that Wall Street expects the company's valuation to reach $2 trillion, with fundraising of up to $100 billion.
According to the Financial Times, last week Anthropic told investors at its San Francisco office that its third-quarter revenue climbed to $16.8 billion, up from $11.5 billion in the second quarter, and noted that the company was also profitable on an adjusted basis.
The massive fundraising stands out amid increasingly fierce competition in this year's IPO market. Earlier this week, South Korean data center provider Elice plunged 32% on its first day of trading after raising $151 million. Nvidia-backed Firmus Grid abruptly shelved its listing plan earlier this month after investors objected to its proposed valuation. Several other companies have also postponed listing plans, citing market conditions.
In recent days, shares of listed AI-related companies have also fluctuated as investors have become more cautious about the AI industry's enormous spending needs. CoreWeave in particular has come under close scrutiny as investors question the relationship between its future revenue prospects and its debt burden.
This shift highlights that investors who enthusiastically bought AI-related companies earlier this year have now become more selective.
One person familiar with the matter said that given Anthropic's enormous size, the timing of its IPO is also expected to have a significant impact on other companies seeking to list in the coming weeks.
Anthropic has established a foothold in the enterprise market with its Claude chatbot, the popular AI coding tool Claude Code and Claude Cowork.
Competitor OpenAI originally planned to hold an IPO this year, but is now expected to list in early 2027.
