Anthropic unveiled its U.S. initial public offering paperwork on Monday, setting up for a market debut that would test investors' willingness to fund the AI juggernaut's expenses amid growing concerns over debt-fueled spending. The company, founded in 2021 by former OpenAI researchers, is known for its Claude family of AI models.
Revenue has surged to $4.59 billion in 2025 and $16.29 billion in the first six months of 2026, but operating losses also widened to $8.06 billion in 2025 and $693 million in the first half of 2026.

Anthropic is pressing ahead with its IPO plans even as a once-busy fall listing calendar has thinned out, with market volatility prompting companies to delay offerings. The IPO would give Anthropic access to a deep pool of capital to fund its costly AI ambitions, which require heavy investment in computing infrastructure to develop and operate sophisticated models. Global equities have sold off sharply as investors grow uneasy with the debt-fueled AI investment boom and start to doubt if the trillions being poured into data centers, chips and computing capacity will generate returns fast enough to support lofty valuations. Higher borrowing costs and rising bond yields have added to their caution.
Some current and prospective investors are valuing Anthropic at about $1.5 trillion, down from roughly $2 trillion a week ago, after the AI startup disclosed some financial details at a recent investor event, Reuters reported. The filing confirmed a ser
