Kalshi
The event tracks whether a specific public figure makes original posts, quote posts, or reposts on a social media platform during a particular month in the year 2026, excluding replies. It focuses on the activity level of this individual on the platform. The outcome depends solely on their posting behavior during that specified time frame.
If @realDonaldTrump posts, quote posts, and reposts on X above 0 times (not including replies) in Oct 2026, then the market resolves to Yes.
Currently, prediction market odds often reflect a different perspective than traditional polling averages. Polls capture stated preferences at a single point in time, while this market aggregates the beliefs of individuals who have ‘skin in the game’ – they are financially incentivized to accurately predict the future. This can lead to divergences, particularly on events with significant uncertainty or where respondents may be hesitant to express their true beliefs. It’s common to see this market adjust more quickly to new information than polls, as traders continuously update their assessments.
On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing the probability of @realDonaldTrump tweeting in October 2026. The price of a contract reflects the market's collective belief about that probability; a higher price indicates a greater likelihood. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market dynamically adjusts as traders place orders, creating a real-time assessment of the event's potential outcome. This mechanism allows for efficient price discovery and reflects the aggregated wisdom of the crowd.
This market resolves around Nov 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will depend on whether a tweet originating from the verified @realDonaldTrump account on X (formerly Twitter) is posted at any point during the month of October 2026. The outcome will be determined by a review of publicly available data and archival records to confirm the presence or absence of such a tweet. No further details on the verification process are available.
