Anthropic, the maker of the AI chatbot Claude, files preliminary paperwork for a United States initial public offering (IPO), multiple outlets report. The company is described as doing so confidentially, starting a process that could lead to its stock being sold to the public. NPR and other sources note that the deal could become one of the largest IPOs in U.S. history, reflecting investor demand tied to the broader boom in artificial intelligence companies. Canadian outlets similarly frame the move as a test of investor appetite for the AI sector amid high expectations. Al Jazeera reports that Anthropic does not disclose key details of the offering, including the size or terms, in the information available so far. While the reports agree on the filing and the intent to pursue an IPO, they do not provide figures on valuation, pricing, or timing. The filings mark the start of a regulatory and market process that may culminate in a public offering if the company proceeds and regulators clear the offering terms.
