Anthropic’s confidential S-1 filing in June 2026 and selection of Nasdaq for an October listing have anchored trader consensus at a 95.9% implied probability for a 600B+ closing market cap. The company’s May Series H round already valued it at $965 billion post-money on a $65 billion revenue run rate, with public targets now circling $2 trillion and Nvidia reportedly eyed as a major anchor investor. This positions the Claude developer for one of the largest IPOs on record, well above historical AI precedents. Key near-term catalysts include the expected public prospectus release in late September and the mid-October roadshow, though any slippage in regulatory review or a sharp market correction could still compress the debut valuation.
