Flash2026-10-29

Anthropic filed its S-1 registration statement with the SEC on October 29, 2026, seeking a Nasdaq listing under ticker 'ANT'. Multiple sources report a potential $2 trillion valuation and up to $100 billion in proceeds. As a pre-revenue AI infrastructure company, its filing triggers heightened SEC scrutiny on revenue recognition policy, stock-based compensation accounting (ASC 718), and R&D capitalization methodology.
