Anthropic, the company behind AI chatbot Claude, has filed initial paperwork for an initial public offering. The filing did not disclose the size or terms of the offering, according to Al Jazeera.

The move comes as investor enthusiasm for artificial intelligence companies reaches a fever pitch. Anthropic's IPO, along with those of other AI firms like OpenAI, could rank among the largest in U.S. history, NPR reported.

The AI sector has seen a flood of capital in recent years, with companies racing to commercialize large language models and other generative technologies. Anthropic has positioned itself as a safety-focused alternative to competitors.

For investors, the offering represents a chance to bet on a fast-growing but still unprofitable industry. The company will need to demonstrate a clear path to sustained revenue amid fierce competition and regulatory scrutiny.

Some analysts warn that lofty valuations may not hold if the AI market cools or if regulatory hurdles emerge, particularly around data privacy and model safety.
