Saturday, November 14, 2026: The Anthropic IPO is set to become the second-biggest stock market debut on record. The company behind Claude expects to price its shares on Wednesday, November 18, and to begin trading on Nasdaq under the ticker ANT on Thursday, November 19, according to its IPO website (filed with the SEC). At the top of the $70 to $78 range, the 825 million shares on offer raise up to $64.4 billion, more than any IPO except SpaceX in June 2026.

SpaceX raised $75.0 billion at $135 per share in June 2026. Anthropic follows with up to $64.4 billion, well ahead of Saudi Aramco with $25.6 billion in 2019, Alibaba with $21.8 billion in 2014 and Facebook with $16.0 billion in 2012. Tesla raised $226 million in 2010.

After the offering Anthropic will have about 13.09 billion Class A and Class N shares outstanding. At $70 to $78 that is a market value of $916 billion to $1.02 trillion. New investors will hold only 6.3%, and the IPO plus a concurrent $26.0 billion private placement with AMD, Broadcom, Google, Micron, Microsoft, Nvidia and TSMC Partners brings in about $84.6 billion in net proceeds. Third-quarter 2026 revenue was $17.0 billion, more than twelve times the prior year.

That can push the first price far from the offer price, in either direction.
