Anthropic is filing confidentially on what could be the largest initial public offering ever

Make Anthropy Secret Paperwork for an initial public offering on Monday, the first step in what could be a successful debut for A $965 billion company. Filing with US regulators is another entry in what appears to be a dossier A historic year for public offerings like artificial intelligence Laboratories compete to fund their expensive research.

Anthropic announced the submission in an unsigned two-paragraph piece Blog postNoting that the amount of money it seeks to raise – and at what valuation – has not been specified. The timing of the IPO “depends on market conditions and other factors,” the company said. The announcement comes just days after Anthropic revealed a 65 billion dollars Fundraising tour.

The company declined to comment beyond its blog.

Anthropic, led by CEO Dario Amodei, joins a crowded space. OpenAI is rumored to be targeting its own IPO as soon as September. SpaceX, which owns Elon Musk’s xAI company, secretly filed its IPO paperwork in April and published it on May 20. It is now targeting a stock market debut on June 12 and seeking a valuation of $1.75 trillion. Reuters reported.

The three companies are racing to secure access to funding that would help pay for the computing resources needed to train frontier AI models with increased capabilities. Anthropic’s annual revenue, based on sales from an unspecified time frame last month, is $47 billion, the company said last week. But it spent more money on cloud computing and thousands of employees, resulting in losses.

Monday’s filing with the U.S. Securities and Exchange Commission allows regulators to provide comments on the lengthy document, which talks about Anthropic’s goals, financing and challenges. (The company can then make adjustments based on that feedback.) Preparing for an IPO is complex, requiring companies to shore up their accounts, tighten various internal policies, and have a clear sales pitch to investors.

The long-awaited debut could unleash a wave of wealth throughout San Francisco, where Anthropic is based. Some Anthropic employees previously converted a portion of their shares into cash by selling them privately to investors before the IPO. But more Anthropic employees may cash out or sell larger stakes as part of the IPO process, turning dozens or even hundreds of paper millionaires and billionaires into actual billionaires.

The IPO could also be a boon for major shareholders like Amazon and investors who made some of the first bets on the company, including Skype co-founder Jan Tallinn.

If all goes well, Anthropic’s IPO could rival SpaceX’s as the largest ever. But Anthropic’s complex corporate structure and management, including its status as a public benefit corporation that responds in part to a committee the company calls the Long-Term Benefit Fund, can lead to delays and loss in valuation.

Anthropic has distinguished itself from other AI labs by focusing heavily on courting business clients. Its code writing model, Claude Code, is widely considered best-in-class.

But the company faced some setbacks. Earlier this year, US Defense Secretary Pete Hegseth sanctioned Anthropic under two different government supply chain laws to remove the company’s AI cloud models from the military and other federal agencies. Hegseth viewed the company’s ethical positions—including its resistance to unsupervised use of Claude in high-stakes scenarios—as a threat to national security. Specifically, Anthropic executives emphasized that the government’s desire to unilaterally deploy emerging AI models for tasks like weapons targeting and mass domestic surveillance is not a use case the company will allow.

The labels threaten to lose billions of dollars in sales this year. The executives said. Anthropic has filed a lawsuit to overthrow it Ongoing legal battles.
