Anthropic’s quiet move toward Wall Street is colliding with an overheated AI market and mounting questions about whether customers are getting their money’s worth.

On June 1, Anthropic disclosed that it had confidentially submitted a draft registration statement on Form S-1 to the U.S. Securities and Exchange Commission, giving it “the option to go public after the SEC completes its review.”¹ The company emphasized that the number of shares and price “have not yet been set” and that the proposed offering will depend on “market conditions and other factors.”¹

Within hours, tech and financial media framed the filing as the start of an IPO race among the world’s largest AI labs. TechCrunch reported that Anthropic, maker of the Claude AI models, had filed confidentially for an IPO after a Series H round that valued it “close to $1 trillion,” with the listing timing dependent on “market conditions and other factors.”² Axios noted that Anthropic’s $65 billion raise at a $965 billion valuation was the largest venture round ever and “saw Anthropic leapfrog rival OpenAI on valuation.”³

Business Insider likewise described Anthropic as “blazing toward blockbuster IPO” territory after submitting its confidential S-1, with the filing cast as a “major step in the rush toward a public listing, as Anthropic and rival OpenAI race to claim billions of dollars and stake their claim on the AI narrative.”⁴ The Verge called it a “key milestone,” noting that last week’s fundraise put Anthropic at a $965 billion post-money valuation, making it “the world’s most valuable startup” ahead of OpenAI.⁵

By June 2, attention shifted to the risks behind the headline numbers. Axios highlighted how corporate customers — Anthropic’s core market — are rethinking AI bills, warning that this enterprise focus could become the company’s “Achilles heel if businesses start to rebel against AI costs.”⁶ A separate Axios analysis laid out IPO “storylines to watch,” including Anthropic’s early “pole position in the AI ‘race’” and the possibility that corporate cutbacks in AI spend turn its enterprise strategy into a “double-edged sword.”⁷

Market watchers are split on what comes next. Business Insider framed Anthropic’s listing as a test of how investors value enterprise AI, quoting analysts who say Claude is “poised to win enterprise AI” even as it trails consumer rivals — and that “how the markets value that will make or break Anthropic’s IPO.”⁸ Another Insider piece argued the move “adds fresh momentum to a surge of high-profile technology offerings that could reshape public markets.”⁸ The Financial Times, for its part, said Anthropic’s plan “sets up race with OpenAI and SpaceX, testing Wall Street’s appetite for the AI boom.”⁹

Industry competitors stress that going public is just one front in a broader contest. OpenAI chief executive Sam Altman, responding to Anthropic’s filing, told CNBC that “there is a race to deliver the best technology, build the best business,” while describing an IPO as simply “a financing event.”⁸ He argued that AI will not be winner-take-all, saying the world will “rightly demand…multiple providers” for such critical infrastructure.⁸

As the SEC review proceeds, investors will parse Anthropic’s eventual public S-1 for answers on growth, costs, regulation and governance. Axios notes that the confidential filing “officially started its IPO clock” and that Anthropic could potentially hit markets as soon as mid-August, depending on how it sequences its debut relative to SpaceX and OpenAI.⁷
