Perplexity's firm commitment to a 2028 IPO, reaffirmed by CEO Aravind Srinivas in June 2026 regardless of OpenAI and Anthropic's confidential filings, drives the dominant 66.5% market-implied probability of no listing before then. The AI search startup has prioritized building a high-growth business with annualized revenue exceeding $750 million by August 2026, up sharply from earlier in the year, while its latest closed valuation sits near $20 billion amid reported talks for a higher round involving Nvidia. Traders appear to view this deliberate timeline as credible given the company's revenue traction and strategy of waiting for clearer AI sector performance data after peer debuts, with limited near-term catalysts expected to shift the outlook before 2028.
