Perplexity AI’s current implied valuation sits near $20–22 billion based on secondary market prices around $70 per share and the September 2025 Series E at $20 billion post-money, while reports of a potential Nvidia-led round at a $30 billion pre-money valuation remain unconfirmed as of early October 2026. Revenue momentum provides the key support, with annualized recurring revenue reaching approximately $750 million by August–September 2026 after the February launch of its Computer AI agent and shift to usage-based pricing, representing roughly triple the level from late 2025. With the October 31 resolution date approaching rapidly, any closing of a new equity round, additional enterprise traction, or material secondary trading updates could shift market-implied odds before month-end, though historical precedent shows private valuation resets typically require formal funding announcements rather than incremental product news alone.
