Description

This market will resolve according to the number of times NYC Mayor Zohran Mamdani (@NYCMayor), posts on X between October 16, 12:00 PM ET and October 23, 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 different outcomes regarding the number of posts made by the NYC mayor between October 16 and October 23, 2026. You can view the current odds, price history, and 24-hour trading volume directly on the Polymarket interface. Currently, the 24-hour volume is $5,861 and the total volume is $11,056. This allows participants to see how the market is interpreting the likelihood of various posting frequencies.

Currently, it's difficult to directly compare this market to polling averages as polls focused on the specific number of mayoral posts made during a defined timeframe are unlikely to exist. However, broader polling data regarding the mayor’s approval rating and public sentiment towards their policies could offer some insight into potential activity on social media. If public opinion shifts dramatically, this market may reflect those changes before traditional polls do, as traders react to perceived impacts on the mayor’s communication strategy. This market represents a forward-looking assessment, unlike polls which capture a snapshot in time.

On Polymarket, this market is priced through a continuous double auction, meaning traders buy and sell shares representing their belief about the outcome. The price of a share reflects the implied probability of that outcome occurring. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information becomes available, the price will adjust accordingly, offering a real-time assessment of expectations. The current price indicates what the collective wisdom of the market believes the likelihood is of a specific number of posts being made by the mayor during the specified period.

This market resolves around Oct 23, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will be based on the total number of posts made by the NYC mayor on their official social media accounts (e.g., X, Facebook, Instagram) between October 16, 2026, and October 23, 2026, inclusive. The final count will be sourced from publicly available data and verified against credible public sources to ensure accuracy and transparency. Traders will then be able to claim their winnings based on the final outcome.

Several signals or events could significantly move this market. Major policy announcements, unexpected crises requiring the mayor’s immediate attention, or shifts in public opinion regarding key issues could all influence the mayor’s posting activity. A significant increase or decrease in the mayor’s approval ratings, as reflected in polling data, could also impact the market. Furthermore, any changes to the mayor’s social media strategy or the appointment of a new communications director could be catalysts for price movement in this market.
