Anthropic Files S-1, Targets Mid-November IPO With Valuation Up to $2 Trillion

Anthropic, the developer of the Claude AI model, has filed its S-1 paperwork publicly with the Securities and Exchange Commission, according to a report from Yahoo Finance cited by Breitbart News. The filing sets the stage for what could be one of the largest stock market listings in history, with a possible debut as early as the week of November 16.

The company has not confirmed an official IPO date, but SEC rules narrow the timeline. Anthropic released its filing to the public on October 26. Companies that used the private SEC draft review process must wait at least 15 calendar days after going public before starting a formal roadshow. That puts the earliest possible roadshow start at November 10. Yahoo Finance calculated that Friday, November 13, is the earliest date Anthropic could set its offering price, and Monday, November 16, is the earliest possible day it could begin trading.

SpaceX offers a recent comparison: it filed in June and went from public filing to first trade in 23 days. If Anthropic follows a similar timeline, it could debut Wednesday, November 18, according to the analysis cited by Breitbart.

Anthropic is trading under the placeholder ticker ANTH.PVT for now and plans to list as ANT on the Nasdaq Global Select Market, Yahoo Finance reported.

**Financials Show Rapid Growth, Heavy Spending**

Anthropic's S-1 reveals explosive revenue growth alongside enormous spending commitments. According to the filing, revenue grew 1,206 percent to $33.2 billion through the first nine months of the fiscal year ended September 30. Operating losses narrowed to $1.3 billion in that period, down from $5.2 billion a year earlier.

A separate analysis by the investment site Twelfth Magpie, citing the S-1 and amended paperwork, reported that in the first six months of 2026, Anthropic's revenue hit $16.3 billion, a 1,300% year-on-year increase, with a $974 million operating profit in the second quarter. The company's third-quarter revenue surged 1,127% to $17 billion, though that represented a slowdown from the second quarter's 144% quarter-on-quarter growth. Anthropic swung to an operating loss of $567 million in the third quarter, primarily due to securing $5 billion worth of short-term compute.

The dev.to newsletter ThursdAI, which analyzed the S-1, reported that Anthropic made $974 million in operating profit in Q2 2026 with an 85% gross margin. The newsletter noted that in 2025, Anthropic made a billion or two per quarter, then in Q1 2026 made about $4.7 billion, and in Q2 made $11.55 billion — more than doubling in a single quarter.

Anthropic disclosed spending commitments totaling $895.4 billion, overwhelmingly tied to compute and infrastructure, with $69.8 billion of that due within the next 12 months, according to the S-1 cited by Breitbart. Twelfth Magpie reported that roughly $70 billion of this is due by September 30, 2027, and almost $450 billion before the end of 2030. The company confirmed it will be building more of its own infrastructure rather than relying on third-party cloud service providers, some of whom are rivals.

**Risk Factors Include Existential Threats**

Among the risk factors Anthropic cited are a narrow customer base and dangers tied to advanced artificial intelligence, including what the filing describes as "existential risks to humanity," according to Breitbart. The S-1 includes a line that sufficiently advanced AI systems "could... pose catastrophic or existential risks to humanity," as noted by the ThursdAI newsletter.

Twelfth Magpie also noted that the company admits cheaper, good-enough models may eventually win over many enterprise workloads, pointing to a significant risk of commoditization, especially if low-cost Chinese AI labs proliferate globally.

**Investors and Valuation**

A long list of investors stands to benefit from the IPO. Amazon and Alphabet, both major backers, are likely among the financial winners, according to the S-1 cited by Breitbart. Other venture capital investors include Spark Capital, Menlo Ventures, Coatue Management, and Lightspeed Venture Partners, and funds managed by Fidelity and Blackstone also hold stakes.

In April, Anthropic ran a tender offer that let shareholders sell stock; CEO Dario Amodei, President Daniela Amodei, and other executives sold approximately $4.66 billion worth of shares in that sale, Breitbart reported.

Breitbart reported that Democrat mega-donor and former Google CEO Eric Schmidt is likely to make $10 billion from the IPO, based on his early investment in 2021 when the company was valued at $461 million. Using the $2 trillion valuation figure, Schmidt's stake would boost his net worth by about one-third, to nearly $80 billion, according to Bloomberg's wealth index cited by Breitbart. Schmidt and Anthropic both declined to comment.

Investors last week signaled a fair valuation for Anthropic of between $1.8 trillion and $2 trillion, according to Breitbart. Twelfth Magpie reported a valuation range of $1.5 trillion to $2 trillion.

**Market Commentary**

Jim Cramer said bears may derail Anthropic's IPO, making it a key test for AI valuations amid debates over losses, pricing and bubble risks, according to a Benzinga summary.

Michael Burry questioned whether Anthropic's cloud partners are helping polish expenses and margins ahead of its IPO, another Benzinga summary reported.

Anthropic hasn't disclosed how many shares it plans to sell or at what price range. The company's S-1 shows more than 1,900 customers with $1 million or more of revenue on a trailing-12-month basis, and roughly 250 customers with $10 million or more, according to Twelfth Magpie.
