Description

This market will resolve according to the number of times NYC Mayor Zohran Mamdani (@NYCMayor), posts on X between October 2, 12:00 PM ET and October 9, 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

On Polymarket, the dashboard for the NYC mayoral posts market tracks the implied probability of various outcomes regarding the number of posts made by the NYC mayor between October 2nd and October 9th, 2026. You’ll find a real-time view of the current odds, the trading volume over the past 24 hours, and a price history chart illustrating how sentiment has shifted over time. Currently, the 24-hour volume is $1,190 and the total volume is $7,817. This provides a comprehensive overview of how traders are assessing the likelihood of different post counts.

Currently, it's difficult to directly compare the odds in this market to traditional polling data, as polls focusing on the specific number of social media posts by the NYC mayor are unlikely to exist. However, prediction markets often incorporate information *ahead* of polls, reflecting real-time events and expert opinions. If polling data emerges closer to the resolution date, it will be interesting to see if it aligns with the collective wisdom expressed through this market. Discrepancies could indicate that traders believe factors not captured in polls—such as the mayor’s communication strategy—will significantly influence the outcome.

On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in different outcomes. The price of a share directly reflects the implied probability of that outcome occurring. As more traders participate, the prices adjust to reflect the collective forecast. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price is determined solely by supply and demand, meaning that increased buying pressure will drive up prices, while increased selling pressure will lower them. This dynamic pricing ensures that the market reflects the most up-to-date information available to traders.

This market resolves around Oct 9, 2026, with the outcome confirmed once the total number of posts made by the NYC mayor between October 2nd and October 9th, 2026, is verifiable from credible public reporting. The resolution will be based on a count of official posts across the mayor’s verified social media accounts. The exact methodology for counting posts will be determined by Polymarket and will be publicly available prior to resolution. Traders should review the platform’s documentation for the specific criteria used to determine the final outcome of this market.

Several signals or events could significantly move this market. Major policy announcements from the mayor, shifts in public sentiment towards the mayor’s administration, or unexpected events requiring frequent communication could all influence the number of posts made. Any changes to the mayor’s communication strategy, such as a planned increase or decrease in social media activity, would also be a key driver. Additionally, external factors like a city-wide crisis or a major political event could prompt the mayor to increase their online presence, impacting the outcome of this market.
