Investors are expressing skepticism about Anthropic’s planned or expected IPO prospects, particularly around whether the company could justify a $1.5 trillion valuation. Several outlets report that potential investors are signaling caution and are pushing for terms and valuations they view as more attractive before committing to the offering.

The coverage frames this as part of a broader “AI backlash” or investor hesitation that could affect timing and price. One report points to doubts that the IPO could proceed on a valuation seen as at the top of expectations, while another describes investor concerns about whether recent discussions of the figure are realistic. Overall, outlets largely align on the core theme: major investors are not fully convinced by the $1.5T valuation premise and want to see better economics or clearer conditions before participating.
