Anthropic’s confidential S-1 filing in June and ongoing preparations for a November 2026 listing remain the dominant driver of market-implied odds. On October 14, the company hosted pre-IPO investor meetings that highlighted third-quarter revenue of $16.8 billion—up 45% sequentially from $11.6 billion—with adjusted profitability, supporting a targeted valuation above $2 trillion versus the $965 billion post-money valuation from its May Series H round. Lead underwriters Morgan Stanley, Goldman Sachs, and JPMorgan are guiding toward a roadshow the week of November 9 and trading before Thanksgiving, with a Nasdaq listing planned. Strong annualized revenue run-rates near $65 billion contrast with persistent operating losses, leaving execution on cost discipline and regulatory scrutiny as key variables ahead of the public S-1 release.
