Anthropic files confidentially for IPO ahead of OpenAI

Anthropic has taken the first formal step toward a public listing. On June 1, the Claude maker submitted a confidential IPO filing to the SEC, meaning regulators can review the paperwork before the company decides whether, when and at what price to go public.

The timing follows a dramatic funding round: Anthropic reportedly raised $65 billion at a $965 billion valuation, its first valuation above OpenAI’s. The company was founded five years ago by former OpenAI employees led by Dario Amodei, originally positioning itself as the AI lab with a heavier safety emphasis.

The numbers now look less like a small safety lab and more like a giant enterprise software business. Annualized revenue is said to have reached $47 billion, up from roughly $10 billion a year earlier, while Bloomberg’s cited second-quarter expectation is $10.9 billion, more than double the previous quarter.

Anthropic is not alone at the gate. OpenAI is also expected to pursue a listing this year, while SpaceX, linked in the source framing with xAI, has also filed recently. Analysts quoted by the source described the moment as an opening of the IPO market’s floodgates, with Anthropic’s possible window around late October if conditions hold.
