Anthropic’s reported selection of Nasdaq for its planned IPO, backed by Bloomberg and other outlets citing people familiar with preparations, has driven the overwhelming 91.6% market-implied odds. The AI developer behind the Claude large language model has advanced confidential filings, secured major underwriters, and targeted a November debut at a potential $2 trillion-plus valuation, aligning with Nasdaq’s track record hosting recent mega-tech listings like SpaceX. Traders view this as settled given the company’s tech-sector ties and index eligibility benefits. Realistic challenges include last-minute regulatory hurdles, sharp market volatility delaying or altering the venue, or an unexpected shift toward NYSE for broader institutional appeal, though no credible signals support such changes.
