Anthropic’s October 26 S-1 filing with the SEC positions the company for a Nasdaq listing under ticker ANT as early as mid-November 2026, following Goldman Sachs and Morgan Stanley’s lead underwriting roles. Revenue reached $16.3 billion in the first half of 2026, reflecting over 1,200% year-over-year growth and a $47 billion-plus annualized run rate after the May Series H round at a $965 billion valuation. Operating losses narrowed to $693 million while adjusted operating income turned positive, though a reported $80.7 billion net loss stemmed largely from non-cash convertible bond accounting. Traders weigh this explosive AI-driven expansion and targeted $1.5–2 trillion IPO valuation against high compute costs, safety disclosures, and post-SpaceX market volatility ahead of the post-election window before Thanksgiving.
