## What was reported

The Ninth Circuit left in place its 4 Aug 2026 panel ruling that vacated the preliminary injunction barring Perplexity's Comet agent from Amazon.com. No judge requested an en banc vote. The panel had found Amazon unlikely to win its CFAA claim because users, not Perplexity, access Amazon's systems. The case returns to district court.
