This market will resolve according to the iOS app, ranked #1 in the United States on the iPhone Apple App Store's overall Top Charts under "Free Apps", as of 12:00 PM ET on the specified date. To find the overall chart, click "Apps" at the bottom of the US iOS App Store app, scroll down to "Top Free Apps" and click "See All". Then under "Free Apps" in the "Top Charts" section, you'll see the list that will be used as the resolution source to this market (https://apps.apple.com/us/charts/iphone).ChatGPT's dominance as the leading free app on the US Apple App Store, with traders assigning it a 100% implied probability for April 28, stems from its current #1 ranking on real-time iPhone charts, ahead of rivals like Claude by Anthropic and Google Gemini. This positioning reflects sustained user adoption of OpenAI's AI chatbot app, bolstered by ongoing enhancements in large language model capabilities, image generation, and cross-device sync, which have reclaimed the top spot after brief challenges from competitors earlier in 2026. The app's sticky engagement in productivity and search outpaces social or gaming alternatives. While resolution hinges on end-of-day charts, realistic challengers include a surprise viral update from Meta AI or Claude, or abrupt shifts in App Store algorithms, though trader capital shows strong conviction in stability.
