Perplexity AI’s last confirmed post-money valuation stands at $20.39 billion following its September 2025 Series E-6 round, with secondary-market and implied marks recently around $19.7–22.5 billion as of early October 2026. Annualized recurring revenue reached roughly $750 million by August 2026, driven by the Perplexity Computer AI-agent launch and usage-based pricing, though no new priced equity round has closed since then. Nvidia reportedly explored participation in a potential round above $30 billion in late August, but that transaction remains unconfirmed. With the October 31 resolution date only weeks away and the company’s stated IPO target in 2028, near-term valuation shifts hinge primarily on whether any interim funding or secondary transaction materializes before month-end.
