Anthropic files to go public on Nasdaq under the ticker ANT

Anthropic has filed publicly for its IPO. The S-1 went to the SEC on 26 Oct. The company plans to list its Class A common stock on the Nasdaq Global Select Market under the ticker ANT. It hasn't set a share count or price range yet, but reports say the offering could value the Claude maker at more than $2 trillion, above SpaceX's $2.1T June raise.

The numbers are large in both directions. Revenue grew 1,368% year over year for the quarter ended 30 June. Over the same stretch, cloud costs rose about 300%. Anthropic posted a $80.7B net loss for the first half of 2026, almost double its $42B loss for all of 2025. Goldman Sachs and Morgan Stanley are leading the deal, as they did on SpaceX's record listing. The risk factors cover safety, reliable compute and an "evolving, uncertain, and at times divergent" global regulatory landscape.

Trading is expected in mid-November, slightly later than first planned because of recent market volatility. Some reports point to 19 or 20 Nov.

Why it matters: this is the first time public-market investors can buy a frontier AI lab directly, and the price they pay for ANT will set a benchmark for what AI growth is worth against losses this size.
