Anthropic’s public S-1 filing on October 26, 2026, with strong third-quarter revenue reaching $17 billion and its first operating profit in Q2, has anchored trader expectations for a November 2026 listing. Reports consistently point to marketing beginning the week of November 9 and trading the week of November 16—before Thanksgiving—under the ticker ANT on Nasdaq, supported by a syndicate led by Goldman Sachs and Morgan Stanley. Explosive growth in its Claude large language models, alongside $1.5–2 trillion valuation targets, reinforces the near-term consensus, though recent AI-sector volatility and investor pushback on pricing have introduced modest uncertainty around exact timing. The roadshow and any final regulatory clearances remain the key near-term catalysts.
