Trader consensus on Anthropic’s IPO timing reflects recent schedule adjustments and strong momentum in its artificial intelligence business. Reports from early September 2026 indicate the company now expects to file its public S-1 in late September, begin the roadshow in mid-October at the earliest, and target a listing days before the November U.S. midterm elections, aligning with the 59.5% implied probability for October and 24.4% for November. This follows a confidential June 2026 filing, a May Series H round at a $965 billion valuation, and revenue run-rate growth above $65 billion by July. Ongoing talks with Nvidia as a potential $10 billion anchor investor for a possible $100 billion raise at roughly $2 trillion further support the compressed fall window, while any additional delays or regulatory scrutiny could shift odds toward later 2026 or 2027 outcomes.
