For the purposes of this market, only main feed posts, quote posts and reposts will count.

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 displays the current odds of various outcomes regarding the number of posts made by the NYC Mayor between September 11 and September 18, 2026. You’ll find a price history chart illustrating how those odds have changed over time, giving insight into trader sentiment. The dashboard also shows the 24-hour trading volume, currently at $617, and the total market volume, which is $15,125. This provides a clear picture of market activity and interest in this specific event.

Currently, it’s difficult to directly compare the odds in this market to traditional polling averages, as polls focusing on the specific number of social media posts from the NYC Mayor are unlikely to exist. However, this market reflects a collective assessment of the mayor’s likely behavior and communication strategy during that week. If public opinion polls were to indicate a shift in the mayor’s popularity or a change in communication priorities, we might expect to see corresponding movements in the odds offered within this market. The market offers a unique, forward-looking perspective beyond simple approval ratings.

This market resolves around Sep 18, 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 during the specified period, from September 11 to September 18, 2026. The exact count will be determined by publicly available data, ensuring a transparent and objective resolution process. 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 from the NYC Mayor, particularly those related to communication or public engagement, could influence trader expectations. Unexpected events requiring the mayor’s immediate attention – such as a natural disaster or public health crisis – might lead to increased or decreased posting activity. Changes in the mayor’s staffing or communication strategy could also be a catalyst. Finally, any significant shifts in public sentiment towards the mayor, even if not directly related to posting frequency, could impact the odds in this market.
