Perplexity AI’s last confirmed post-money valuation stands at approximately $20 billion following its September 2025 Series E extension. Annualized recurring revenue reached roughly $750 million by August 2026, more than tripling from early-year levels, driven by the February launch of its Computer AI agent and usage-based pricing. Secondary-market marks have remained near $19–20 billion through October 2026. Reports in August indicated Nvidia was discussing participation in a new round above $30 billion, though no closing has been announced. Traders monitoring December 31 resolution will focus on whether a priced financing or sustained secondary uplift materializes before year-end, alongside broader AI funding sentiment and any shifts in monetary policy or risk appetite that influence private-market multiples.
