This market tracks whether Elon Musk will post between 220 and 239 times on X (formerly Twitter) between September 15th and September 22nd, 2026. Currently, Polymarket gives this outcome a 100.0% probability, while the second most likely outcome – 240 to 259 posts in the same timeframe – is at 0.1%. The market resolves based on the post count from Elon Musk’s X account, https://x.com/elonmusk. Traders should watch the activity on Musk’s X account as we approach September 22, 2026, which marks the end of the betting period and the final day for posts to be counted towards resolution.
This market will resolve according to the number of times Elon Musk (@elonmusk), posts on X from September 15 12:00 PM ET to September 22, 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 on the main feed such as https://x.com/elonmusk/status/1786073478711353576 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). Community reposts which are not counted by the tracker not count toward the total. 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.
Currently, it's difficult to directly compare the odds in this market to traditional polling averages, as predicting the tweet count of an individual is not a common subject for public opinion surveys. However, analysts who follow Elon Musk’s social media activity may offer estimates of his likely posting frequency. This market provides a different perspective, reflecting the collective wisdom of traders who are incentivized to accurately forecast the outcome. Discrepancies between expert predictions and this market’s probabilities could indicate areas where traders possess unique insights or anticipate unforeseen events influencing Musk’s activity.
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 reflects the probability of that outcome occurring, as determined by supply and demand. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The more traders believe an outcome is likely, the higher the price of its corresponding shares will rise. This dynamic pricing ensures that the market odds continuously adapt to new information and changing sentiment regarding Elon Musk’s potential tweet output during the specified period.
This market resolves around Sep 22, 2026, with the outcome confirmed once the total number of tweets posted by Elon Musk on X (formerly Twitter) between September 15 and September 22, 2026, is verifiable from credible public reporting. The final count will be sourced from publicly available data and assessed to determine which outcome corresponds most accurately to the actual number of tweets. The resolution will reflect the total number of posts, regardless of content or engagement, made during the defined timeframe.
Several signals or events could significantly impact this market. Major news events involving Elon Musk or his companies (Tesla, SpaceX, X) could influence his social media activity. Changes to X’s platform policies or Musk’s personal usage patterns could also be catalysts. Unexpected announcements, controversies, or periods of heightened public attention surrounding Musk are likely to drive trading activity in this market. Furthermore, any indication of Musk’s planned schedule or communication strategy during that week could cause shifts in the probabilities reflected in this market.
