Anthropic’s selection of Nasdaq as its listing venue for a planned November IPO underpins the overwhelming 94% market-implied odds, driven by multiple September confirmations from people familiar with the matter and alignment with the exchange’s recent capture of major AI debuts such as SpaceX. The company, maker of the Claude large language model, has advanced confidential S-1 filings and pre-IPO investor meetings while reporting rapid revenue growth to multi-billion annualized levels, positioning it alongside other high-growth technology firms that favor Nasdaq’s platform dynamics and index eligibility. A shift to NYSE or another venue remains possible only in the event of an unforeseen regulatory intervention or strategic pivot before trading begins, though no such developments have surfaced in recent reporting.
