Predicting the highest temperature of a specific city on a given day is a niche but standard weather market. For the general public, it is not a daily concern unless they have a specific interest, but it is not completely bizarre.

Resolution primarily relies on a third-party tracker (xtracker) and involves technical nuances like whether 'replies appear on the main feed' and if deleted posts survive for more than ~5 minutes. These technical definitions may deviate from intuitive manual counting on Truth Social, creating a moderate rule trap.

Predicting the exact number of posts a politician makes in a specific week is a classic niche novelty topic. The general public usually doesn't care about such hyper-granular data, although it is relatively common among political prediction market participants.

Between May 8 and May 9, 2026, as Trump's posting frequency on the first day of the tracking period was significantly lower than his recent norm, multiple high-frequency options (140-159, 160-179, 200+) plummeted to below 10c after briefly spiking to around 30c on May 8. Simultaneously, mid-to-low frequency options (60-79, 80-99, 100-119) surged, with '60-79' jumping from ~2c to 15c and '100-119' rebounding from 9.5c to 26.5c, showing a sharp downward revision of total expected posts based on real-time data. Between May 7 and May 8, 2026, the '80-99' option crashed from 28.5c to 7.5c, while the '120-139' option spiked from 17c to 30c before falling back to 20.5c, driven by expectation adjustments as the start date approached and exacerbated by low liquidity. Between May 5 and May 6, 2026, several low-frequency options (e.g., <20, 20-39, 40-59, 60-79) plummeted from around 25c. This occurred because early market illiquidity, which uniformly priced all options, was corrected as traders priced in Trump's true, highly active posting habits.

Betting on the specific daily high temperature of a single city is a niche, novelty market typically used for daily platform engagement rather than serious, macro-level forecasting.

The market rules contain notable nuances: it counts main feed posts, quote posts, and reposts, but excludes normal replies. However, replies on the main feed are counted by the tracker. Furthermore, deleted posts are counted if they remain available long enough to be captured (~5 minutes). X itself acts as a secondary source if the tracker fails. These specific definitions and potential tracker discrepancies present a moderate risk.

While betting on Elon Musk's actions is somewhat common in prediction markets, predicting the exact number of tweets he makes within a specific one-week timeframe is highly trivial and novel. Few people would naturally ponder this exact number.

May 8, 2026 - May 10, 2026, the price of the 140-159 bucket surged consistently from ~18.5c to 33.5c, and the 120-139 bucket rose from ~8.25c to 26.55c. This is because real-time tracking data indicated Musk's posting frequency is at a moderate-to-low pace, prompting the market to further upgrade the probabilities of the lower-mid ranges. May 6, 2026 - May 9, 2026, the price of the 140-159 bucket surged consistently from 13c to 31.5c, and the 120-139 bucket rose from 4c to 17.65c. The reason is that real-time tracking data indicated Musk's posting frequency is at a moderate-to-low pace, prompting the market to heavily upgrade the probabilities of the lower-mid ranges. May 5, 2026 - May 9, 2026, the price of the 100-119 bucket plummeted from 23c to ~5.85c, the 200-219 bucket dropped from 26c to 4.5c, and the 220-239 bucket dropped from 29.5c to 2.15c. This was caused by the sharp reduction in uncertainty as time progressed, consolidating the probability mass tightly into the mid-range (120-179).

The rules rely heavily on a specific third-party tracker (xtracker) and have nuanced conditions for deleted tweets (must survive ~5 mins) and replies. This introduces the risk of discrepancies between manual counting and tracker data, as well as potential API downtime.

The general public absolutely does not care about or track the exact weekly tweet count of a government social media account. This is a classic novelty market artificially manufactured purely for prediction market speculators.

May 8, 2026 - May 9, 2026, the price of the '160-179' option rose from 34.5c to 42.5c, and the '200+' option rose from 18c to 28c. This is because the actual posting frequency increased the probability of higher frequency ranges, causing market funds to concentrate in the higher ranges. May 6, 2026 - May 8, 2026, the price of the '120-139' option plummeted from 22c to 9.5c, and the '200+' option fell from 31.5c to 9c. This is because as time progresses, the actual posting frequency stabilized in a higher median range (e.g., 160-199), causing the market to sell off overly low or extreme options. May 5, 2026 - May 6, 2026, all options quickly diverged from their initial disorganized state (around 40c), as the market rapidly adjusted to a fair valuation based on the latest average daily tweets by the White House (about 20-30).
