While weather prediction markets exist, forecasting the exact maximum daily temperature for a specific city remains a relatively niche topic that the general public does not typically ponder on a regular basis.

The rules contain specific pitfalls, heavily relying on a designated third-party tracker (xtracker) rather than the raw actual tweet count. It excludes normal replies but includes main-feed replies, and deleted tweets only count if they survive for ~5 minutes to be captured. These technical nuances can easily cause discrepancies between a bettor's manual count and the final resolution.

Forecasting the exact number of posts by a specific public figure within a mere 48-hour window is highly marginal. The general public does not think about or care for such highly fragmented and random data, making it a classic novelty market.

May 11, 2026 - May 12, 2026, the price of the <40 option rebounded from 44.5c and rose to 64.5c, while the 40-64 option further fell from 42.5c to 32.5c. This was because the real-time posting data early in the tracking window was low, significantly boosting market confidence that the total would be under 40. May 11, 2026, the price of the <40 option surged from 50c to 64.5c before dropping back to 44.5c within a single day, while the 40-64 option fell from 42.5c to 30.5c and rebounded to 42.5c. This was caused by the tracking period just starting, where Musk's real-time activity triggered intense speculation and position adjustments among traders. May 9, 2026 - May 11, 2026, the price of the <40 option surged from 25c to roughly 50c, while the 40-64 option dropped from 55c to 43c, and the 65-89 option dropped from 17.5c to 6.5c. This occurred as traders continued to observe clear signs of a recent slowdown in Musk's posting frequency, anticipating lower activity over the upcoming 48-hour window.

Predicting the highest temperature in a specific city on a given day is a typical weather-based prediction market. While normal for locals, it is a relatively niche and slightly quirky topic from a global macro perspective.

2026-05-12 - 2026-05-12, the price of 30°C surged from 7.65c to 80c, and 31°C or higher surged from 3.5c to 23.05c. This occurred because the actual observed temperature on the resolution day exceeded earlier forecasts, landing in the 30°C+ range. 2026-05-11 - 2026-05-11, the price of the 27°C option surged from 22.5c to a peak of 46c before settling back to 32c. The reason is that as the resolution day approaches, the latest hourly weather forecasts provided higher certainty for this specific temperature range. 2026-05-10 - 2026-05-11, prices for 26°C, 28°C, and 29°C experienced frequent fluctuations (e.g., 28°C rose from 23.5c to 34.5c), reflecting trading battles caused by the slight uncertainty in late-spring temperature forecasts near the coastal/inland boundary.

May 10, 2026 - May 11, 2026: The price for 37°C plunged from 21.5c to 7c, and '38°C or higher' dropped from a peak of 21.5c to 4.5c. This occurred because updated forecasts from the Pakistan Meteorological Department (PMD) confirmed that Karachi's maximum temperature will remain stable at 34-36°C, with extreme heatwave alerts targeted at upper Sindh rather than the coastal city, significantly reducing the likelihood of temperatures exceeding 37°C.
