The rules contain several potential pitfalls: standard replies do not count, but 'main feed replies' do, which can cause ambiguity. Deleted posts only count if caught by the tracker within a ~5-minute window, creating a technical risk. Furthermore, resolution strictly relies on Polymarket's proprietary tracker, which might desync from X's actual data.

Betting on the exact number of tweets a billionaire makes in a specific 48-hour window is a highly niche and novelty-driven entertainment market. The general public does not ponder this, though it serves as a typical, highly entertaining meme market within crypto prediction circles.

Between May 3, 2026, and May 4, 2026, the '40-64' option price fell from 73.5c to 66.5c, while the '65-89' option surged from 12.6c to 29.65c. This occurred because Musk's posting frequency continued to climb as the tracking period neared its end, increasing the tail risk of entering the 65-89 range. On May 3, 2026, the '<40' option plummeted from 61.5c to 0.05c, while the '40-64' option surged from 35.5c to 75.5c, and the '65-89' option recovered to 26.75c. This occurred because, as the tracking period progressed, Musk's posting volume increased significantly, breaking earlier expectations of an ultra-low count. The market confirmed the final total would easily exceed 40 posts, locking largely onto the 40-64 range. Between May 2, 2026, and May 3, 2026, the '<40' option surged from 13c to 61.5c, while the '65-89' option plummeted further from 22.5c to 3.7c. This occurred because, during the first dozen hours of the tracking period, Musk's actual posting volume was significantly lower than expected, prompting the market to heavily downgrade its forecast for his total posts. Between April 30, 2026, and May 2, 2026, the '40-64' option price continued to rise from 43.5c to 65.5c, while the '65-89' option fell further from 38c to 16.5c. This occurred as the tracking period was about to start, and the market adjusted expectations based on his latest activity levels, solidifying the belief in a moderate posting frequency. Between April 30, 2026, and May 1, 2026, the price of the '65-89' option dropped significantly from 38c to 26.5c, while the '40-64' option rose from 43.5c to 51.5c. This reflects an initial shift in market expectations regarding Musk's posting frequency, predicting it will more likely fall in the lower range.

While weather prediction markets and derivatives exist in professional fields, betting on the exact daily high temperature at a specific airport remains a relatively niche and novelty topic for general prediction market participants.

May 2, 2026 - May 3, 2026, the price of the 24°C option dropped from 32.5c to 8c, as weather forecasts increasingly ruled out lower temperatures as time progressed. May 2, 2026 - May 3, 2026, the price of the 26°C option surged from 21.5c up to 46c before settling at 34c, driven by expectations of higher temperatures in updated forecasts. May 2, 2026 - May 3, 2026, the 25°C option rose steadily from around 30c to 52.5c, as it emerged as the most likely outcome nearing the expiration date.

Predicting the daily high temperature for a specific city is a relatively niche weather derivative market. While weather forecasts are common, ordinary people rarely bet on the exact integer degree Celsius of a specific day unless they are weather enthusiasts or traders.

Predicting the exact highest temperature of a specific city on a given day is a relatively niche but common type of derivative in prediction markets. While the general public doesn't think about exact local temperatures daily, it is a standard topic among prediction market participants.

There is a moderate divergence. Mainstream weather forecasts predict a high of 16°C-17°C for May 4, yet the prediction market assigns over 40% probability combined to 14°C and 18°C, while 16°C is priced at only 12c. The market pricing deviates notably from the consensus meteorological forecasts.

Predicting the daily high temperature for a specific location is a relatively niche data prediction market. While everyone checks the weather, ordinary people rarely bet on the precise temperature range of a specific weather station on a given day.
