Highest temperature in Amsterdam on August 15?

Platform comparison

Market context

Amsterdam's weather on 15 August 2026 will be measured against historical August temperatures at Schiphol Airport, the official meteorological station serving the city. The market resolves based on the highest temperature recorded in Weather Underground's Daily Observations table for that date, with settlement occurring at noon UTC on the day itself.

August temperatures in Amsterdam typically range between 17°C and 23°C, with occasional peaks above 25°C during warm spells. Historical data from the Royal Netherlands Meteorological Institute shows that temperatures exceeding 28°C on any single August day occur roughly once every three to five years in the region. The current 0% crowd probability suggests traders are pricing in an expectation below the lowest historical threshold for that specific date, or reflecting genuine uncertainty about conditions two years forward. Comparable August 15th observations from the past decade show highs between 19°C and 26°C, establishing a baseline for typical conditions.

The primary catalyst affecting this market's resolution will be European summer weather patterns in August 2026, particularly high-pressure systems moving across the continent. Traders should monitor seasonal forecasting models released in July 2026 and any significant climate anomalies reported by meteorological services in the weeks preceding the settlement date. Real-time conditions on 15 August itself will determine the final outcome, with no intermediate announcements or declarations altering the underlying weather measurement.

UK Frequently Asked Questions

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Which platform has the deepest political liquidity?

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.

How fast do political markets react to news?

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.
