Anthropic Files for IPO, Overtaking OpenAI in Valuation Race

The AI Arms Race Hits Wall Street
After months of industry speculation regarding which AI powerhouse would first blink in the race toward a public offering, Anthropic has made the first move. On Monday, the company officially submitted a draft registration statement to the U.S. Securities and Exchange Commission (SEC), signaling the start of its transition from a venture-backed darling to a publicly traded entity.
The move isn’t just a bureaucratic milestone; it is a statement of dominance in valuation. According to data from its most recent funding round last week, Anthropic is now being valued at $965 billion post-money. This figure pushes the company past its primary rival, OpenAI, which currently holds a post-money valuation of $852 billion. If these numbers hold through the IPO process, Anthropic will enter the public market as the most valuable startup in history.
The Strategy of Confidentiality
Anthropic has opted to file its registration statement confidentially. While a common tactic for high-profile tech debuts, this choice means the public will be kept in the dark regarding the company’s internal machinery for the time being. Crucial disclosures—including executive compensation packages, detailed financial statements, and a comprehensive list of business risks—will remain shielded from the public eye until the SEC clears the filing for a formal launch.
This strategic opacity allows Anthropic to refine its narrative and pricing before facing the scrutiny of institutional investors and retail traders. Given the volatility of the AI sector, where burn rates are astronomical and revenue models are still being stress-tested, the ability to control the flow of financial data is a significant tactical advantage.
Intertwined Interests: The SpaceX Connection
The timing of the filing is as much about market positioning as it is about capital. Anthropic is hitting the tape just two weeks before SpaceX’s highly anticipated June 12 IPO. The relationship between the two companies has evolved into a critical piece of infrastructure; Anthropic recently inked a massive deal to pay $15 billion annually to utilize SpaceX’s specialized data centers.
This symbiotic relationship highlights a broader trend in the AI industry: the shift from software agility to hardware dependency. By securing massive compute capacity through SpaceX, Anthropic is attempting to solve the ‘compute bottleneck’ that has plagued the scaling of Large Language Models (LLMs). SpaceX, meanwhile, is poised to raise $80 billion in its own debut, potentially the largest IPO in global history.
A Shift in the Competitive Landscape
For years, the narrative surrounding AI has been a binary struggle between OpenAI and Anthropic. However, the legal and financial landscape is shifting. OpenAI recently secured a victory in a high-profile legal battle with Elon Musk, with a judge dismissing Musk’s claims based on the statute of limitations. While that legal cloud has cleared for OpenAI, the financial momentum appears to be swinging toward Anthropic.
The move to go public represents a fundamental shift in how AI companies are viewed. No longer just research labs chasing AGI (Artificial General Intelligence), these firms are now being valued as the primary utility providers of the next industrial revolution. The market’s reaction to Anthropic’s valuation will serve as a litmus test for whether the ‘AI bubble’ has a sustainable floor or if the valuations have finally outpaced the actual utility of the software.
