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.

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.

While monitoring global shipping chokepoints is standard for macro supply chain and geopolitical analysts, predicting the exact number of ship transits for the Strait of Hormuz is moderately niche and rarely considered by the general public.

The Strait of Hormuz is the most critical global chokepoint for energy transport. A sharp drop in transits (e.g., falling into the 0-10 bracket) would typically indicate an extreme military blockade or war, triggering a structural spike in Crude Oil prices and dragging down broad equity indices like the S&P 500 due to macro shock. It serves as an excellent hedge for geopolitical tail risks.

The rules exclude normal replies but state that replies recorded on the main feed by the tracker (xtracker) will count, as will deleted posts if they remain for ~5 minutes. This technical reliance on a specific tracking tool creates a moderate risk of discrepancy compared to direct manual observation on X.

Predicting the exact number of posts from a government social media account within a specific week is a very niche and novel topic that falls far outside the general public's normal sphere of interest.

May 11, 2026 - May 12, 2026, the 180-199 option climbed further from 81c to 98.75c, as extreme proximity to settlement and tracking data almost completely locked in this range. May 10, 2026 - May 11, 2026, the 180-199 option climbed further from 77.5c to 87.5c, as the approaching settlement and tracking data further locked in this range. May 9, 2026 - May 11, 2026, the 160-179 option plummeted from 42c to 1.25c, the 180-199 option surged from 50c to 81.5c, and the 140-159 option completely flatlined to 0.05c. This is because with only 1 day left until settlement, the base post count has effectively ruled out counts below 180, pointing heavily to the 180-199 range. May 9, 2026 - May 10, 2026, the YES price for 180-199 surged from 43c to 77.5c, while 160-179 plummeted from 38c to 7.5c. This is because with less than 2 days until expiration, the consistent high-frequency posting data from the White House account has given the market extremely high confidence that the final count will fall in the 180-199 range. May 8, 2026 - May 9, 2026, the YES price for 180-199 surged from 19.5c to a peak of 58c (before settling at 45.5c), while 160-179 dropped from 55.5c to 31c (then recovering to 40c). This is because as expiration nears, the actual tracked post count is trending higher than previously expected, shifting probabilities toward the 180-199 bracket. May 8, 2026, the YES price for 140-159 plummeted from 35.5c to 6.5c, 180-199 rose from 24c to 45c, and 200+ dropped from 14.95c to 6.45c. This is because participants adjusted expectations based on the latest post tracker data, causing extreme mispricings to collapse and redistribute. May 5, 2026 - May 8, 2026, the 160-179 option surged from 28c to a peak of 62.5c, 140-159 bounced to 34.5c after dropping to 19.5c, and the 200+ option spiked from 4c to 20c. This is due to a lack of market liquidity and irrational capital placing chaotic bets across high-frequency brackets, causing a severe premium in aggregate prices. May 2, 2026 - May 3, 2026, the prices of all low-probability high-frequency posting options saw varied movements. Notably, the Yes price for 140-159 fell from 48c to 37c, and 100-119 fell from 48c to 29.5c. This is likely due to the market initially being in an extremely illiquid and randomly priced state, followed by a slight regression towards reality.
