This market will resolve according to the number of times NYC Mayor Zohran Mamdani (@NYCMayor), posts on X between September 4, 12:00 PM ET and September 11, 2026, 12:00 PM ET. For the purposes of this market, only main feed posts, quote posts and reposts will count. Replies will NOT count towards the total - however, replies which are recorded on the main feed will be counted by the tracker. Deleted posts will count as long as they remain available long enough to be captured by the tracker (~5 minutes). The resolution source for this market is the "Post Counter" figure for posts found at https://xtracker.polymarket.com. Individual posts can be viewed by clicking "Export Data". If the tracker does not update correctly in accordance with the rules, X itself may be used as a secondary resolution source.
