Description

This market will resolve according to the number of times NYC Mayor Zohran Mamdani (@NYCMayor), posts on X between July 14, 12:00 PM ET and July 21, 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.

Frequently asked questions

The NYC Mayor social media activity market dashboard on Polymarket tracks real-time odds and trading volume for predictions on how many posts the sitting NYC Mayor will publish across all social media platforms during the week of July 14–21, 2026. The interface displays current market prices, historical price movements, and 24-hour trading activity. This market aggregates trader sentiment into a probability estimate, allowing participants to buy or sell shares based on their forecast of mayoral social media output during that specific seven-day window. The dashboard updates continuously as new trades execute, reflecting the collective prediction of the market participants.

Prediction markets and polling serve different purposes in forecasting. While traditional polls measure public opinion on specific questions at a single point in time, this market reflects the aggregated financial commitments of traders who profit or lose based on accuracy. Traders often incorporate polling data, expert analysis, and real-time developments into their positions, making market odds dynamic and responsive. For mayoral social media activity, prediction markets may capture nuanced expectations about campaign intensity, news cycles, and communication strategies that static polls cannot. The market price represents a continuous, incentive-driven forecast rather than a snapshot of opinion.

On Polymarket, this market is priced through an automated market maker that converts trader buy and sell orders into real-time probability quotes. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders purchase shares representing different outcome ranges (for example, "15–20 posts" or "21–25 posts"), and the price of each share reflects the collective assessment of that outcome's likelihood. As more capital flows into a particular outcome, its price rises, and alternative outcomes become cheaper. The spread between bid and ask prices tightens with higher volume, rewarding active participation. Settlement occurs when the actual post count is verified, and winning shares are redeemed at full value.

This market resolves around Jul 21, 2026, after the conclusion of the July 14–21, 2026 observation period. The outcome is determined by counting the total number of posts published by the NYC Mayor across all social media accounts during that week. Once the event window closes, the actual post count is verified against credible public sources and official social media records. The market then settles based on which outcome bracket the final count falls into, and traders holding winning shares receive their payout. Resolution typically occurs within a few business days of the period's end.

Several factors could shift trader expectations before Jul 21, 2026. Major political announcements, campaign events, or crises involving the NYC Mayor could trigger increased social media activity. Changes in the mayor's communication strategy, staff turnover, or shifts in local political dynamics may also influence posting frequency. Media coverage of the mayor's office and public controversies often correlate with heightened online engagement. Additionally, broader trends in political communication and social media adoption could affect baseline activity levels. Traders monitor news, polling, and historical posting patterns to adjust their positions, so any unexpected developments during the observation week itself will drive real-time price movements.
