Artificial intelligence giant Anthropic has engaged Morgan Stanley and Goldman Sachs to lead its initial public offering, with JPMorgan also participating, according to Beating monitoring. On June 2, the company announced it had confidentially submitted a draft S-1 registration statement to the U.S. Securities and Exchange Commission (SEC), formally launching its path to the public markets.
Top-tier underwriting and confidential filing
The selection of Morgan Stanley and Goldman Sachs as joint lead underwriters underscores the scale and anticipation surrounding the offering. Confidential submission of the S-1 allows the company to work with regulators on the document before it is made public, a common practice among large tech firms to minimize early market noise. The addition of JPMorgan brings further Wall Street heavyweight support to the syndicate.
Record $65 billion Series H round, near-trillion-dollar valuation
Anthropic’s IPO plans come on the heels of a massive $65 billion Series H funding round completed at the end of May 2026. That round was led by Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital, with participation from global strategic and financial investors including Amazon, Google, and Singapore’s Temasek. The post-money valuation reached $965 billion, making Anthropic the world’s most highly valued private AI startup, overtaking rival OpenAI.
Early investor windfall and surging revenue
As Anthropic prepares to go public, early backers are seeing substantial paper gains. Bloomberg reported that Salesforce, which began investing in the company in early 2023 with a cumulative outlay of around $50 million, now holds a stake worth approximately $5 billion—a nearly 100x return. The disclosure drove Salesforce shares up 10% in a single day. At the same time, Anthropic disclosed that its annualized revenue run rate has officially surpassed $47 billion, demonstrating powerful monetization momentum that adds further valuation support ahead of the IPO.
