Recent Bloomberg and Business Insider reporting citing sources familiar with preparations indicates Anthropic selected Nasdaq for its planned IPO, driving the market's strong 94.4% implied probability for that outcome. The choice aligns with the AI developer's growth profile, large-cap technology precedents such as SpaceX's listing, and eligibility for the Nasdaq-100 index, especially as the Claude maker advances confidential S-1 filings and targets a multibillion-dollar raise potentially exceeding $2 trillion valuation. Delays pushing the debut toward mid-November have not altered the reported venue. A shift to NYSE or another exchange would require a major reversal in banker guidance or strategic priorities, scenarios viewed as low-probability given the consistency of current signals.
