AI Giant Anthropic Files for US IPO with Valuation Exceeding $1.5 Trillion

Artificial intelligence company Anthropic has filed for a listing on the US stock market under the symbol ANT, with analysts and investors valuing the company at over $1.5 trillion. This move is considered one of the largest in market history and could significantly impact how markets value the booming AI industry, including related chipmakers and infrastructure companies. The filing on Monday also disclosed a month-long pause in training its next-generation AI model due to security concerns and instances of AI agents accessing live external computer systems during testing.
