AI giant Anthropic files to make stock market debut

Anthropic publicly filed for an initial public offering (IPO) on Monday morning in what is expected to be a historic stock market debut.

The S-1 filing with the Securities and Exchange Commission (SEC) brings the Claude maker a step closer to becoming the first large frontier AI lab to go public. It is expected to be a major test for investors’ interest in the technology.

The stock will trade under the ticker ANT on the Nasdaq exchange, according to the filing, and could happen as soon as November.

The filing showed Anthropic’s revenue has drastically jumped in the past year, yet the company reported a net loss of $80.7 billion in the first half of this year. The company was valued earlier this year at $965 billion by private investors, The Associated Press reported .

It comes as AI safety concerns dominate headlines , following various security breaches and warnings from executives including Anthropic CEO Dario Amodei about the technology’s risks to society .

In Monday’s filing, Anthropic highlighted various risks of the technology, including the potential for cyberattacks, design of biological weapons or mass surveillance by government.

“We consider it our personal responsibility to help the world understand these risks, to prevent or mitigate them when they arise from our AI models, and to work with governments and the rest of the industry to address them at a societal level,” the company wrote.

Anthropic confidentially filed paperwork with the SEC in early June, though no other details were released at the time. A week later, rival AI company OpenAI also confidentially filed to go public , though it is not clear when the ChatGPT maker will take the next step.

Anthropic’s IPO could be the largest in history, beating the record recently set by Elon Musk’s SpaceX last June, in which shares opened at $150.

The AI firm has tried to set itself apart from its competitors as an advocate for public safety and clashed with the Trump administration this year over that position.

Tucked into the 335-page document, Anthropic alludes to this, telling investors, “The political environment and our engagement with policymakers and public positions on AI regulation and safety could subject us to heightened scrutiny, political backlash, or disproportionate regulatory action.”

The Pentagon took the unprecedented move in February of labeling Anthropic a supply chain risk after the company demanded its technology not be used in fully autonomous lethal weapons or for the mass surveillance of Americans.

Anthropic sued the Pentagon in California and Washington, D.C., arguing the Defense Department retaliated against the AI firm for what it believes is a “protected viewpoint” of the company. A federal judge in California ruled the blacklist was illegal and that it violated the First Amendment and the due process clause of the Fifth Amendment.

A three-judge panel at the D.C. Circuit Court of Appeals sided with the Trump administration, setting the stage for a potential Supreme Court fight.
