This market will resolve according to the iOS app, ranked #2 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. If the chart is unavailable at 12:00 PM ET, this market may remain open for up to 48 hours to allow for the data to become available. If the data remains unavailable, this market will resolve according to the last published ranking. 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).Trader sentiment reflects a closely contested race among AI, social, and utility apps for the #2 free spot on the US Apple App Store on September 18, with ChatGPT, Vinted, TikTok Pro - Events, and similar options each carrying roughly 23% implied probability. Competitive dynamics center on recent feature updates, marketing pushes, and user engagement spikes that can rapidly alter download rankings.

Google Maps trails at 8.5% on steady but less volatile utility appeal. Proximity to the date heightens sensitivity to any final announcements or viral triggers that could tip the leaderboard.
