Highest temperature in Taipei on August 20?

Platform comparison

Market context

The market concerns the highest temperature recorded at Taipei Songshan Airport Station on 20 August 2026, with settlement based on the Daily Observations table from Weather Underground rather than summary figures. The 0% crowd probability suggests traders expect the specified temperature range to fall outside historical norms for that date, or reflect uncertainty about which range the market has defined as the resolution target.

August temperatures in Taipei are consistently elevated, with historical daily highs typically ranging between 32–35°C during the peak summer season. The Songshan Airport station, located in the city's east district, records temperatures influenced by urban heat island effects and proximity to the Taipei Basin. Comparable August 20th observations from prior years provide the baseline: reviewing Weather Underground's historical data for Taipei shows that extreme heat days above 36°C occur but remain uncommon, whilst readings below 30°C are rare. The current zero probability implies the market's defined range sits either well above or below these typical August patterns.

Traders monitoring this market should track seasonal weather pattern forecasts released in the months preceding August 2026, particularly any advisory from Taiwan's Central Weather Administration regarding monsoon activity or heat dome formation. El Niño or La Niña conditions developing through 2025–2026 could shift baseline temperatures materially. Real-time forecast updates from meteorological services typically become reliable only 10–14 days before the settlement date, meaning the market will likely see significant probability shifts in mid-August as deterministic forecasts crystallise around specific temperature ranges.

How accurate are political prediction markets?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Trump Prediction route into the same order book at 0% fees.

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
