Although 2026 is a midterm year for a Republican president, which typically favors the opposition, I...

Significant divergence exists. Mainstream political forecasting models (like Cook or Sabato) typically rate open seats in such deep red states as 'Likely Republican' (implying >80% win probability), whereas the prediction market currently prices it at only 63%. The market appears to be over-hedging against the midterm penalty for the President's party while underestimating the stickiness of Iowa's rightward shift.

March 22, 2026: The price of '16°C' crashed from a morning peak of 40¢ to 23¢, suggesting the market realized earlier bets on 'extreme warmth' were overly aggressive and is correcting. Simultaneously, '14°C' experienced high volatility, recovering to 27¢ after a flash crash to 12¢ earlier in the day, indicating capital is rediscovering the value of this middle-ground option. March 21-22, 2026: '15°C' climbed from 35¢ to 40¢ before retracing to 36.5¢, highlighting its status as the battleground option anchored by the AccuWeather forecast.

Polymarket prices imply a much higher probability for '16°C' (23%) compared to '13°C' (6%), which sharply diverges from the mainstream forecast by Google/The Weather Channel (56°F/13°C). The market is effectively ignoring the TWC forecast, lopsidedly betting on outcomes even warmer than AccuWeather (15°C), indicating a significant irrational bias.

This is an extreme case of market mispricing. With less than 24 hours to settlement, the resolution ...

March 21-22, 2026, the price of '16°C or higher' surged from ~8c to 56.8c, as the market erroneously traded on KMA's high-temperature forecasts for downtown Seoul (16-18°C), ignoring the temperature differential at the airport location. March 21-22, 2026, the price of '13°C' crashed from ~30c to 2.3c, as herd mentality drove capital into the high-temp options, leaving the option most aligned with meteorological models (Wunderground forecasts 13°C) severely oversold.

There is a total divergence between market implied probabilities (16°C+ > 50%) and the resolution source weather forecast (13°C). Mainstream media is reporting warming in Seoul (~17°C), but traders are ignoring that the prediction market specifies Incheon Airport (13°C) as the resolution location.

The resolution source Wunderground (based on IBM/TWC data) and Google Weather (same source) currentl...

Weather prediction is a niche market. While temperature is a common topic, betting on the exact temperature of a specific city on a specific date is relatively vertical. Most people wouldn't participate unless they specifically track local forecasts.

From March 20 to March 21, 2026, the price of '23°C' crashed from 26c to 7.5c, '22°C' dropped from 26c to 12c, and '14°C or below' fell from 26c to 9c. The reason is that weather models have converged on the 17-18°C range as the date approaches, causing the market to discard the previously uniform pricing on extreme high and low temperature options.

While the market correctly identifies 17°C and 18°C as favorites, it still implies a ~60% combined probability for temperatures 19°C and above. However, forecasts from Wunderground and CMA predict highs of 17-18°C with rain, making temperatures above 20°C highly improbable. Market pricing is lagging significantly behind the updated, cooler forecast.
