Anthropic’s advanced IPO preparations, including its November 10 S-1/A filing that set a $70–$78 per share range for 825 million Class A shares and a concurrent $26 billion private placement with investors including Google, Nvidia, and AMD, have driven overwhelming trader consensus around a November 2026 listing. The company launched its roadshow shortly after, with expectations for pricing on November 18 and first Nasdaq trading as ANT on November 19, supported by run-rate revenue reaching $81 billion and strong AI sector positioning relative to peers. While the filings and timeline indicate high likelihood of completion this month, realistic challenges such as last-minute regulatory scrutiny, broader market volatility, or shifts in investor demand could still affect the exact launch window.
