BREAKING: OpenAI Rival Anthropic Confidentially Files For IPO After Elon Musk’s SpaceX

Anthropic, the AI company rivaling OpenAI, has been submitting a draft registration statement for an initial public offering (IPO). The submission to the U.S. Securities and Exchange Commission (SEC), though the submission is under a confidentiality agreement.

Anthropic Files S-1 Draft For IPO Before OpenAI

Bloomberg ETF analyst Eric Balchunas wrote on X “Anthropic confidentially submitted S-1 draft IPO filing to SEC.” It could emerge as one of the most closely followed AI IPOs in history.

Moreover, it’s worth noting that the revelation follows Elon Musk-led SpaceX announcing an IPO plan. Since then, Anthropic has become one of the most valuable private tech companies in the world, thanks to a series of big fundraisers.

It recently raised $65 billion in Series A funding with a valuation of $965 billion, closing in toward the $1 billion mark. It overtook OpenAI, which has a valuation of around $852 billion. The Sam Altman-led AI firm is expected to confidentially file for an IPO. However, Anthropic ended up making the move before OpenAI.

The company has been able to lure a wide range of institutional investors. Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ and XN heavily invested in the firm. Other backers include Fidelity, Blackstone, Jane Street, Temasek, General Catalyst and Lightspeed Venture Partners.

The Surge In Demand For Claude

Growth in the use of its AI assistant Claude is driving the meteoric rise of Anthropic, officials say. It especially involves enterprise customers looking for AI capabilities for coding, research, workflow automation, and other operational support.

The firm said in a previous announcement, “Global enterprises across industries are deploying Claude in their core operations, and a growing number of people around the world use it for their everyday work.”

Anthropic’s revenue has also been strong this year, fueled by a rise in demand for AI services from companies. It includes partnerships with Google, Amazon, and SpaceX.

Chief Financial Officer Krishna Rao said, “Claude is increasingly indispensable to our growing global community of customers, and we work tirelessly to make tools like Claude Code and Cowork more helpful, more powerful, and more adaptable to their needs.”
