Anthropic files for Nasdaq IPO under ticker ANT

Anthropic's filing comes after a period in which the company has positioned itself as highly safety-conscious, founded in 2021 by seven former OpenAI employees who had reportedly lost faith in that lab's ability to develop advanced AI safely. The S-1 leans into that identity: it warns that advanced AI systems could pose catastrophic or existential risks to humanity, be abused by threat actors for cyberattacks or biological weapons, or be used by authoritarian governments to surveil citizens. The company also flags the risk that it could lose control of the models it develops.

The financial picture in the filing shows rapid revenue growth alongside continuing losses. Revenue grew to more than $16 billion in the first half of 2026 from about $4.5 billion in 2025, while the net loss was $80.7 million, compared to $13 billion in the same period last year. The prospectus emphasizes the enterprise business, noting that more than 11,900 customers spent at least $100,000 in the past twelve months, more than 1,900 spent $1 million or more, and roughly 250 spent $10 million or more. The filing does not disclose how much Anthropic plans to raise or its targeted valuation; The New York Times reported in August that it was looking to raise more than $100 billion with a valuation around $2 trillion.

The filing also highlights government risk, specifically noting the Trump Administration's decision to designate the company as a supply-chain risk. Anthropic writes that it cannot be certain resolution of related lawsuits will not adversely affect its ability to sell to government agencies and other customers. The timing stands in contrast to rival OpenAI, which filed confidentially for an IPO in the summer but announced in September that it no longer intended to go public this year, citing concerns over the risks posed to humanity by AI.
