FactSet sees potential AI stock sell-off if Anthropic valuation plunges after IPO

By Public Technologies
  • FactSet's November 12, 2026 analysis found a hypothetical post-IPO Anthropic valuation plunge could trigger a broader AI sell-off.
  • The severe one-day scenario projects a 6.4% Nasdaq 100 decline and a 7.3% drop in the S&P Information Technology index.
  • That scenario also models a 70% VIX spike and a 0.1% decline in US corporate bonds.
  • A moderate one-month scenario projects losses of 4% for the Nasdaq 100 and 5% for the S&P Information Technology index.
  • Equity-heavy strategies face the largest losses across scenarios, while bond-tilted portfolios show small to negligible reactions.
