Perplexity

Perplexity is an AI search and agent company whose Comet browser acts autonomously to browse, compare, and complete purchases across merchant sites on behalf of consumers. Its product triggered a federal injunction by Amazon that is setting early legal precedent for the boundaries of agentic commerce. Perplexity reached a reported valuation of approximately $9 billion in 2025 following multiple funding rounds, placing it among the best-capitalized independent AI companies outside the foundational model tier. The Amazon injunction centers on whether an autonomous agent can access and transact within a retailer's website without explicit permission, a question whose resolution will determine the legal operating conditions for the entire agentic commerce category.
