Anthropic faces investor skepticism over its targeted $1.5 trillion IPO valuation. A recent selloff in technology and AI assets triggered this pushback.

Institutional investors suggest a $1 trillion valuation is more realistic. This sentiment may delay the offering, which was previously expected before Thanksgiving.

Google and Amazon provide significant backing for the OpenAI competitor. Investors await Anthropic's October financial results to evaluate growth momentum. These figures will determine commitments to what could be one of history's largest IPOs.
