This market will resolve according to the number of times NYC Mayor Zohran Mamdani (@NYCMayor), posts on X between July 7, 12:00 PM ET and July 14, 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.

Prediction markets and traditional polls measure different phenomena. While polls ask respondents directly about expectations or preferences, this market aggregates real-money trader bets on an observable outcome—the actual count of mayoral social media posts. Traders often incorporate polling data, news, and historical patterns into their positions, but the market price reflects collective financial commitment rather than survey responses. Over time, prediction markets have proven competitive with or more accurate than polls for event-based outcomes, since traders face direct financial incentives to price information correctly.
On Polymarket, traders buy and sell shares representing different post-count ranges, with the price of each outcome reflecting its implied probability. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market uses an automated market maker (AMM) mechanism, meaning prices adjust continuously as traders place orders, and liquidity is provided through the platform's smart contract. Shares in higher post-count brackets trade at lower prices if traders believe fewer posts are likely, and vice versa. Settlement occurs when the actual count is verified, and winning shares are redeemed at full value.
This market resolves around Jul 14, 2026, once the trading window closes and the week of July 7–14, 2026 concludes. The outcome is determined by the total number of social media posts published by the NYC Mayor across all platforms during that seven-day period. Resolution is confirmed once the count is verifiable from credible public sources, including official social media accounts and reputable news archives. Traders holding shares in the outcome bracket matching the final count receive their payout.
Several factors could shift trader positioning before resolution. Major political announcements, scheduled press conferences, or public crises during the week of July 7–14 may prompt increased mayoral communication. Changes in the incumbent's communication strategy, staffing, or media relations could alter expected post frequency. Real-time social media activity in the days leading up to and during the resolution window will provide concrete signals, causing traders to adjust positions as actual post counts accumulate. News coverage of the mayor's office and broader political developments may also influence expectations.
