Trader consensus on Polymarket tilts strongly toward ChatGPT claiming the #2 spot among free US Apple App Store apps on March 20, with 57.5% implied probability, propelled by its explosive download surge amid viral AI experimentation and OpenAI's aggressive mobile optimizations. Anthropic's Claude follows at 21%, buoyed by recent app updates enhancing multimodal capabilities and positive user buzz on social platforms. Sports contenders like CBS Sports (13.5%) and NCAA March Madness Live (10.5%) reflect peak bracket frenzy during the tournament's opening weekend, but fading against AI momentum; historical data shows AI apps outpacing seasonal spikes. Lower-odds plays like Google Gemini hinge on late search integrations, while shopping and social apps lag without catalysts. Odds may shift with final Sensor Tower rankings.
