Anthropic files for IPO with a possible $2 trillion valuation

By Elena Vasquez

Anthropic filed for an IPO that could value the Claude maker at roughly $2 trillion, placing the listing among the technology industry's largest potential stock market debuts. It submitted a Form S-1 registration statement to the U.S. Securities and Exchange Commission.

The filing reports $16.3 billion in first-half 2026 revenue and an $80.7 billion net loss. Accounting adjustments related to financing instruments contributed substantially, so the reported loss does not equal cash spent running the business.

Anthropic proposes listing Class A common stock on the Nasdaq Global Select Market under ticker ANT. It has not determined the number of shares to offer or the price range. Reuters reported that the company could seek as much as $100 billion, although those offering figures remain unconfirmed.

The company has not confirmed an offering timetable. Its S-1 also links planned expansion to model risk. Anthropic's S-1 says: “Our development of highly advanced models, platforms, and applications and expansion of use cases could further increase the risk that our models cause harm.”

What are the IPO's headline economics?

Anthropic generated $16.3 billion in revenue in the first half of 2026, compared with approximately $1.2 billion in the same period of 2025. The company says operating performance improved.

Anthropic says the revenue growth rate may not be sustainable and could decline. It may also need additional financing sooner than expected and does not anticipate paying dividends in the foreseeable future.

What did Anthropic disclose about existential risk?

Anthropic warns that advanced AI could cause catastrophic or existential risks to humanity. Its scenarios include dangerous capabilities, deceptive behavior, and systems that become difficult for humans to control.

The company describes three safeguards:

• Pre-release testing.
• Red-team assessments.
• Systems designed to detect harmful outputs.

Anthropic may delay training or restrict model releases when safety measures prove insufficient. The company also acknowledges that its mitigation efforts may not succeed.

What do investors see in the margins?

Bloomberg Intelligence technology research head Mandeep Singh said the worst-case scenarios resemble standard risk disclosures for emerging technology companies preparing to go public. He said such language helps address potential liabilities.

Singh cited improving compute efficiency and stronger gross margins as positive signals for investors. He said: “Gross margins are inching closer to 50%, whereas just a quarter back… it was like… sub 20%.” For investors, that shift matters as Anthropic's expansion depends on access to increasingly expensive computing resources.

How large are the compute commitments?

Anthropic expects to spend up to $120.5 billion on compute involving SpaceXAI and Nvidia, alongside up to $114.5 billion with Google through 2033. The commitments support infrastructure needed to train and run advanced models.

Infrastructure obligations of that scale could burden Anthropic if demand falls short of expectations. Investors must weigh rapid revenue growth against those large spending commitments, while the IPO still lacks a confirmed share count, price range and timetable.

Where does Anthropic stand among AI peers?

OpenAI, the maker of ChatGPT, is also preparing for a potential IPO. The company is expanding revenue and computing capacity ahead of a possible listing.

OpenAI CEO Sam Altman said in September that the company would not go public in 2026. He cited AI safety concerns and said the company had more work to do before pursuing a listing.

Cerebras, which develops wafer-scale processors for AI workloads, completed its Nasdaq IPO in May after filing a second time. Anthropic has reportedly targeted mid-November, with November 19 or 20 floated as possible listing dates, but the company has not confirmed either target.
