Anthropic’s S-1 filing on October 26 positions the company for a potential Nasdaq listing under ticker ANT as soon as mid-November, with formal marketing expected to begin the week of November 9 and trading targeted before Thanksgiving. First-half 2026 revenue reached $16.3 billion, reflecting over 1,300% year-over-year growth and a first operating profit in Q2, though the period produced an $80.7 billion net loss driven largely by non-cash note revaluations. Market-implied valuation expectations have moderated to $1.5–1.6 trillion amid recent AI-sector volatility and elevated Treasury yields, below earlier $2 trillion speculation. Key upcoming catalysts include the roadshow launch and final pricing decisions, with the window narrowing before holiday market closures.
