Anthropic, the AI firm behind Claude, has filed its IPO paperwork, revealing a unique corporate structure and massive spending on cloud services.
The filing shows that Anthropic plans to issue a single special share to an entity called the Anthropic Founder LLC, controlled by the company’s seven co-founders, which will hold 50.1% of the voting power.
This unusual setup means that the co-founders will have significant control over the company even after the IPO.
The filing also mentions that Anthropic recorded revenue growth of 1,368% year over year for the three months ended June 30, 2026, with the cost of renting servers and chips growing by 300% over the same period.
Anthropic expects to spend $115 billion with Google and $45 billion with Microsoft for computing infrastructure through 2033.
Despite the impressive revenue growth, the company reported a net loss of $80.7 billion for the first six months of 2026.
The filing highlights concerns over the potential risks of advanced AI systems, emphasizing the need for appropriate safeguards, oversight, and security measures.
Anthropic also noted that it may need to seek additional financing sooner than anticipated due to the high costs of infrastructure.
The company warned that future revenue growth depends on several factors, including the cost of infrastructure.
The filing also mentions the challenges of navigating an evolving regulatory landscape and obtaining insurance for AI-specific risks.

What's still developing
- What happened: Anthropic is gearing up for what could be the biggest IPO ever in a few weeks, and most of what’s in the filing was expected ( we’ve covered it here ).
- But the hefty document, which mentions “revenue” about 460 times and “profit” just three (make of that what you will), has a few surprises: One share to rule them all: Who gets to steer one of the world’s most powerful AI companies once it goes public?
- The first eight candidates must be current or former employees at Anthropic or a nonprofit, but there are no rules for the last two spots (yes, theoretically, one could be you).
- Bottom line: Anthropic is going public with its financials, but if investors want to have a deciding vote in how the company runs, they’ll need to get on a co-founder’s secret list first.
- TL;DR: Among the eye-popping numbers in Anthropic’s now-public IPO filing are some genuinely weird details, including a literal handful of very important customers, a strange corporate structure, and a secret line of succession that the Roy kids would kill for.
- Monday’s filing with the Securities and Exchange Commission showed that Anthropic, like other AI firms, is splashing out unprecedented amounts of cash on cloud services to run its AI models.
- “Profit margins are rising for the Mag 7 but are flat for the S&P 493,” he wrote Sunday, referring to the companies left in the benchmark S&P 500 after subtracting Meta, Microsoft, Alphabet, Apple, Amazon, Nvidia and Tesla.
- “Despite massive investments and widespread hype around artificial intelligence, the technology has delivered zero financial payoff to corporate America outside of tech,” said Torsten Slok, chief economist at investment firm Apollo Global Management.
- “Concerns have been raised both within our organization and by other researchers, regulators, policymakers, and industry participants that sufficiently advanced AI systems could, if not developed, deployed, and operated with appropriate safeguards, oversight, and security measures, pose catastrophic or existential risks to humanity,” the filing said.
- The filing did not include a potential share price, the number of shares to be offered or a valuation for the whole company, all of which will be determined after Anthropic holds a “road show” with investors, prospective investors and its bankers.
- “While we have experienced significant revenue growth in recent periods, our business is highly capital intensive,” the company said.
- Traditional policies provided so-called “silent” cyber coverage, insurers responded with increasingly specific exclusions, and a dedicated cyber insurance market ultimately developed to provide affirmative coverage.
