Anthropic Files for IPO, Kicking Off Landmark AI Public Listing Race
Anthropic, the artificial intelligence company behind the Claude chatbot, has confidentially submitted a draft registration statement with the U.S. Securities and Exchange Commission for an initial public offering, positioning itself as the first frontier AI lab to formally begin the journey toward a Wall Street debut. The move, announced on June 1, signals the start of what analysts are calling the most dramatic tech IPO wave since the dot-com era.
According to AP News, the confidential filing gives Anthropic the option to go public after the SEC completes its review, though the company cautioned that the offering depends on market conditions and other factors. The number of shares to be offered and the price have not yet been determined.
A $965 Billion AI Powerhouse
Anthropic’s IPO filing follows a staggering $65 billion Series H funding round in late May that pushed the company’s post-money valuation to $965 billion — vaulting it ahead of chief rival OpenAI, which is valued at $852 billion. The funding round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital.
The company reports annualized revenue of $47 billion, up from $10 billion the prior year, driven by surging demand for Claude across coding, professional work, and personal tasks. Anthropic recently launched Claude Opus 4.8, boasting improved capabilities in coding and professional workflows.
Founded in 2021 by former OpenAI employees including CEO Dario Amodei, who left over concerns about OpenAI’s direction, Anthropic operates as a Public Benefit Corporation (PBC) — a structure explicitly designed to balance profit motives with broader societal benefits, particularly around AI safety.
The AI IPO Race Takes Shape
Anthropic’s filing sets the stage for a high-stakes race to public markets involving three of the most valuable private companies in the world. Elon Musk’s SpaceX, valued at approximately $1.75 trillion following its merger with xAI, is expected to launch its IPO roadshow on June 4. OpenAI is targeting an IPO as soon as fall 2026, working with Goldman Sachs and Morgan Stanley.
“Anthropic’s move marks a major step for the company to get ahead of OpenAI and an opening of the floodgates for the IPO market, which has been relatively dormant for a few years,” Dan Ives, an analyst at Wedbush Securities, told AP News.
Goldman Sachs has predicted that U.S. IPO proceeds could reach a record $160 billion in 2026, should these marquee names go public this year, according to Fox Business.
Patrick Corrigan, a law professor at Notre Dame University, noted the strategic significance of being first. “I think we were all expecting OpenAI to go first, so it was a little bit surprising,” he told AP News. “Public investors are going to be comparing them roughly around the same time, and so there seems to be a bit of a first movers’ advantage here.”
The Safety Question
Anthropic’s IPO raises fundamental questions about whether a company built on AI safety principles can maintain its mission under the pressure of quarterly earnings expectations. As a Public Benefit Corporation, Anthropic is explicitly designed to prevent short-term profit motives from affecting safety priorities — but going public could test that structure.
According to Straight Arrow News, an IPO would likely compel the company to choose between prioritizing shareholder interests over its current mission and implementing a dual-class share structure similar to Google’s model, which would allow founders to maintain voting authority even with a smaller financial stake.
Tim Law, an analyst at IDC, offered perspective on the industry’s rapid maturation. “We think of these as very mature organizations, but they’ve had to mature in a very short period,” he told AP News. On AI demand, he added: “There are some skeptics around demand. I thoroughly believe the demand is there and will grow.”
Pentagon Blacklisting Casts Shadow
A significant risk factor for the IPO is Anthropic’s ongoing dispute with the U.S. Department of Defense. In late February 2026, the Pentagon labeled Anthropic a “supply chain risk,” effectively blacklisting the company after CEO Dario Amodei refused to remove safety safeguards from the company’s AI model. Defense Secretary Pete Hegseth stated that the company’s refusal “effectively allows a private company to seize veto power over the operational decisions of the United States military.”
Anthropic sued the Trump administration over the designation, but a federal judge ultimately allowed the blacklisting to stand. While the SEC is unlikely to deny the offering based on this dispute alone, the tension with the administration could affect investor sentiment.
What to Watch For
The coming months will determine whether Anthropic’s safety-first approach is rewarded or penalized by public markets. If the market rewards Anthropic with a premium valuation, it could signal that safety is a competitive advantage. If not, it could pressure the company to cut corners — a tension that will define not just Anthropic’s future, but the broader AI industry’s relationship with public investors.
Corrigan offered a cautionary note on the AI IPO wave, drawing parallels to the dot-com era. “Whenever there is speculation, there’s also usually substance and fundamentals,” he said. “The question here is whether the price investors are going to end up paying is going to match up to the substance and fundamentals of what AI is really going to do in the real economy and as a business.”
Key developments to watch include the SEC’s review timeline, the potential public filing of the S-1, Anthropic’s IPO roadshow, and how OpenAI and SpaceX respond to Anthropic’s first-mover advantage.
