Perplexity AI's valuation, currently marked around $19-20 billion on secondary platforms with the last priced round near $20-23 billion in early 2026, hinges primarily on progress toward a potential new equity round amid reported Nvidia investment discussions targeting above $30 billion. Revenue has scaled rapidly to roughly $750 million annualized run rate by August 2026, driven by agent products and enterprise usage, supporting higher multiples in a market pricing AI growth. Secondary share prices have eased modestly in recent months, reflecting tempered sentiment absent fresh primary capital. Key near-term catalysts include any closure of strategic funding before year-end or further ARR updates, though limited time remains through December 31 and broader private-market liquidity conditions could constrain upside. Trader consensus on near-term thresholds will reflect these execution and capital-raising dynamics.
