Perplexity AI's most recent priced round closed at approximately $20B post-money in early 2026, with secondary market marks holding near $19.7B as of October 2026 amid $1.7B total funding raised. Trader focus centers on whether a new equity round materializes by month-end, following August 2026 reports of Nvidia discussing participation above $30B—talks that remain unclosed with no subsequent regulatory filings or announcements. Annualized revenue has scaled rapidly to roughly $750M by August 2026, driven by the Computer AI agent launch and usage-based pricing, supporting a premium multiple near 25-40x but not yet translating into an updated priced valuation. With only 24 days until the October 31 resolution date, any shift would require swift closure of a high-valuation financing or a credible third-party mark exceeding the target threshold, while current secondary pricing and lack of recent catalysts keep implied probabilities anchored to the existing $20B base.
