Trader consensus heavily favors no Anthropic IPO by June 30, 2026 (94.3% implied probability), driven by the absence of any official filing or announcement from the privately held AI firm, which recently raised funds at an $18.4 billion valuation in a March 2024 round led by Amazon and Google, providing ample runway without public market pressures. Anthropic's focus remains on scaling Claude models amid high compute costs and regulatory headwinds like potential AI safety rules, mirroring OpenAI's prolonged private status. Challenges could arise from explosive revenue growth exceeding $5 billion annually, a broader tech IPO resurgence, or investor demands for liquidity events, though no such catalysts have emerged.
