The rules rely on a specific third-party tracker (xtracker) rather than checking the X platform directly. Nuances regarding 'replies recorded on the main feed' and 'deleted posts captured within 5 minutes' can cause discrepancies between the tracker's data and the publicly visible tweet count, requiring users to closely monitor the tracker.

This is a classic exotic/novelty market. The vast majority of people do not naturally care about or predict the exact number of tweets the NYC Mayor makes in a specific week. Such metrics are micro-entertainment events created purely for trading purposes.

April 22, 2026 - April 25, 2026: The dominance of the 20-39 bracket was fully established, surging from 49.5c to stabilize above 97c. Simultaneously, the <20 bracket crashed from 26.9c to around 1.9c, and the 40-59 bracket plummeted from 22c to 2.75c. The reason is that halfway through the tracked period, live post counts virtually guaranteed the final total would land in the 20-39 range, eliminating the possibility of both extremely low and moderately high totals. April 21, 2026 - April 23, 2026: The price of the <20 bracket plummeted from 48c to 2.65c, and the 40-59 bracket crashed from 31c to 2.1c, while the 20-39 bracket surged from around 50c to stabilize above 86c. The reason is that two days into the market period, real-time post tracking data heavily reinforced the certainty of the final count landing in the 20-39 range. April 19, 2026 - April 21, 2026: Multiple unlikely brackets (e.g., 100-119, 140-159, 180-199) experienced extreme volatility and surges exceeding 10c. For instance, the 100-119 bracket skyrocketed from 1.45c to 18.8c. The reason is likely erratic trading due to thin liquidity or attempts by some traders to manipulate the prices of long-shot options.
