According to The Wall Street Journal, citing people familiar with the matter, major investors are growing increasingly skeptical about whether Anthropic's initial public offering (IPO) can achieve its expected $1.5 trillion valuation, following the cooling of AI-related investment trades and a sharp market downturn. The report stated that Anthropic has aimed for an IPO in the week prior to Thanksgiving, with previously anticipated fundraising of up to $100 billion and a potential valuation of around $1.5 trillion. These figures represent the listing plans and valuation expectations mentioned in the report, rather than completed financing or a final offering price.
