Claude by Anthropic holds the strongest market-implied odds at 68% for the #2 free spot on June 5 due to its consistent top-three positioning in recent U.S. App Store charts and sustained download momentum from earlier 2026 benchmark leadership and user migration. The app’s large language model capabilities have driven steady engagement in the productivity category, where AI assistants dominate alongside ChatGPT at #1. Lower probabilities for ChatGPT (30.5%), Google Gemini (20.5%), and others like CapCut reflect their more stable but less surging trajectories amid fluctuating non-AI apps such as Planet Fitness currently holding #2. With resolution just days away, traders appear focused on whether Claude can maintain or improve its rank before the snapshot.
