Anthropic IPO drew demand for 6 times shares on offer

Anthropic's planned initial public offering has attracted orders for about six times the shares available, signaling intense demand for what could become the biggest stock market debut on record. The Claude maker and its co-founders are seeking to raise as much as $64.4 billion in the IPO and another $26 billion in a concurrent private placement, according to company filings. Anthropic is targeting a fully diluted valuation of about $1.4 trillion. Nvidia has agreed to buy roughly $10 billion of shares in the private placement. Anthropic reported an $81 billion revenue run rate as of Oct. 31, up from $71 billion at the end of September.
