Anthropic Publicly Files for US IPO, Targeting Up to $100 Billion

AI research firm Anthropic publicly disclosed its U.S. initial public offering filing on Monday, moving the Claude chatbot developer a significant step closer to a landmark market debut. The company is seeking to raise as much as $100 billion in the offering, according to a Reuters report.

Filing Details Emerge

The public filing follows a confidential submission in June and provides the first official look at the company's ambitious financial plans. The move sets the stage for a potential investor roadshow and eventual listing.

According to Reuters, some current and prospective investors are valuing Anthropic at approximately $1.5 trillion. This figure is down from a previous expectation of roughly $2 trillion. The valuation follows a late May funding round where the company raised $65 billion at a post-money valuation of $965 billion.

AI Industry Heats Up

Anthropic's planned IPO is set to be a major test of public market appetite for the rapidly growing but capital-intensive AI industry. The move comes amid intense competition from other major players in the space.

• Rival OpenAI, the creator of ChatGPT, also reportedly filed confidentially for a U.S. IPO in June.
• OpenAI is said to be seeking investor commitments that could value it at over $1.4 trillion.
• However, OpenAI CEO Sam Altman stated in September that the company will not go public in 2026, creating a potential opening for Anthropic to debut first.

Potential Market Impact

A successful listing of this magnitude would be a pivotal event for U.S. equity markets. An IPO on the scale reported for Anthropic could potentially reshape benchmark indexes, alter investor fund flows, and solidify the broader narrative driving technology stocks. The debut will be closely watched as a barometer for sentiment toward high-valuation growth companies in the current economic environment.
