Anthropic IPO Filing Puts “ANT” on Nasdaq: Could the Claude Maker Debut Bigger Than Bitcoin?

Anthropic, the company behind the Claude AI models, publicly filed for its IPO with the SEC on Monday, October 26, applying to list Class A shares on the Nasdaq Global Select Market under the ticker “ANT”. It could be the largest stock market debut on record, yet the filing leaves the price range blank. The numbers inside it are anything but. The Anthropic IPO prospectus shows revenue of $16.3 billion in the first half of 2026, up from $1.2 billion a year earlier.
