**Anthropic’s reported selection of Nasdaq as the listing venue for its planned IPO drives the overwhelming 95.8% market-implied probability on that outcome.** Multiple credible reports from September 2026 confirm the AI company behind the Claude large language model chose Nasdaq for an October target that has since shifted toward a mid-November debut after delays, aligning with SpaceX’s recent Nasdaq listing and positioning Anthropic for potential Nasdaq-100 inclusion. Strong revenue growth to roughly $65 billion annualized run rate, major backers including Amazon and Nvidia, and a targeted valuation near $2 trillion reinforce trader consensus that the tech-heavy exchange remains the natural home. A shift to NYSE or another venue would require an unexpected reversal of these preparations, which appears improbable given the advanced stage and index eligibility factors.
