Perplexity's valuation sits near $20–23 billion following its Series E rounds through early 2026, with secondary market prices implying roughly $20.5 billion as of early October 2026. Trader sentiment hinges on whether a rumored Nvidia-led round above $30 billion closes before month-end, building on annualized recurring revenue that reached approximately $750 million by August–September after the February launch of its AI agent product and usage-based pricing. The company’s rapid revenue expansion from under $250 million at the start of 2026 reflects strong user growth and enterprise adoption, though unresolved litigation and a planned 2028 IPO timeline limit near-term catalysts. Any funding confirmation or revised secondary quotes could shift implied probabilities ahead of the October 31 resolution.
