Although Environment Canada (EC) downgraded Saturday's high forecast to 5°C (with some tables still ...

March 19, 2026 - March 20, 2026, the price of '6°C or higher' crashed from 66c to 28.5c, while '4°C' surged from 10c to 33.5c and '5°C' rose from 14c to 30c. The driver was Environment Canada updating Saturday's forecast, downgrading the expected high from 9°C to 5°C (some sources say 7°C) and warning of mixed precipitation or lingering cold air, triggering panic selling of the high-temp option in favor of cooler outcomes. March 18, 2026 - March 19, 2026, the price of '6°C or higher' rallied from 26c to 66c as short-term models briefly indicated a warm front would dominate, alleviating cold air concerns.

Significant divergence exists: Mainstream outlet The Weather Network (TWN) still forecasts a high of 9°C for Saturday, whereas Polymarket pricing implies the most likely temperature is only 4°C. The market is positioned more pessimistically than even the official Environment Canada forecast (5°C) and is completely fading the warmer TWN outlook.

March 17, 2026 - March 19, 2026, the price of '14°C or higher' crashed from 27c to ~3c, as weather models firmly ruled out the warm front scenario, confirming a cooler weather pattern. March 17, 2026 - March 19, 2026, the price of '11°C' surged from 10c to over 30c, as earlier model consensus pointed towards the 11-12 degree range, establishing it as the market favorite (despite very recent data suggesting slightly cooler temps).

Significant divergence exists. The market currently prices '11°C' as the highest probability (~30%), reflecting the model consensus from previous days. However, the latest mainstream forecasts as of the evening of March 19 (e.g., The Weather Channel and AccuWeather) have adjusted their expectations down to 9°C-10°C. The market price has not yet fully absorbed this 'cooling' trend, leaving 10°C and 9°C relatively undervalued.

According to the latest forecast from the Taipei Central Weather Administration (CWA) for March 21, ...

March 18, 2026 - March 19, 2026, the price of the 22°C option plummeted from 48.5c to 26c, while 20°C, 21°C, and 23°C also saw corrections exceeding 15c. The reason is a 'valuation correction'; the panic buying triggered by the warming forecast the previous day inflated all prices (sum >> 100), and now, as the resolution date nears, capital is acting more rationally, squeezing out the market premium. March 17, 2026 - March 18, 2026, the price of the 22°C option skyrocketed from 8c to 41c (peaking at 48.5c). The reason was a significant shift in weather models from 'Rain/19°C' to 'Cloudy/18-22°C', triggering a buying frenzy for the warmer range options.

Significant divergence exists. The CWA official forecast caps the high at 22°C, yet the prediction market still assigns a substantial probability (combined ~45%) to temperatures of 23°C and higher. This implies market participants are either hedging against extreme weather risks or betting on non-official meteorological sources, causing market prices to deviate noticeably from official guidance.

While a mayoral election is a standard political event, Toulon is a specific French city. For non-French or non-European political observers, this topic is relatively niche and lacks universal global attention.

March 17, 2026 - March 20, 2026, Josée Massi's price dropped from 66c to 52.5c, with Laure Lavalette rebounding accordingly. The reason was that although Michel Bonnus (LR) withdrew to block the RN, he refused to explicitly call for his supporters to vote for Massi, citing their fractured relationship. This 'soft endorsement' sparked fears that LR votes (~16%) might not effectively transfer to Massi, reigniting panic given the RN's high Round 1 score (42%). March 15, 2026 - March 16, 2026, Josée Massi's price surged from 25c to 63c. The reason was the post-Round 1 announcement that critical 3rd-place candidate Michel Bonnus would withdraw, transforming the race from a 'Triangular' contest (favorable to RN) into a 'Head-to-Head' duel (structurally difficult for RN).
