Highest temperature in Amsterdam on August 14?

Platform comparison

Market context

On 14 August 2026, the highest temperature recorded at Amsterdam Airport Schiphol Station will determine this market's outcome. Resolution relies on the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday peaks diverge from reported highs. The settlement window closes at 12:00 UTC on that date, meaning afternoon temperature spikes after the cutoff will not affect the result.

August temperatures in Amsterdam historically cluster between 18–24 °C, with extremes rarely exceeding 30 °C except during heat waves. The 0% crowd probability suggests traders expect the market's upper threshold to fall outside plausible August conditions for the region, or reflects low participation in a niche weather contract. Comparable Dutch summer forecasts from the Royal Netherlands Meteorological Institute (KNMI) show that temperatures above 28 °C occur in roughly one in four Augusts; anything above 32 °C would constitute an exceptional event. Current crowd sentiment may undervalue tail-risk scenarios, particularly if an Atlantic high-pressure system stalls over northern Europe in mid-August 2026.

Traders should monitor KNMI's extended forecasts from late July onwards and track European weather pattern indices such as the North Atlantic Oscillation. Heatwave warnings issued by Dutch authorities in early August would signal material upside risk. The specific reliance on Schiphol's automated station data—rather than city-centre observations—means that airport microclimates and sensor calibration become relevant; Schiphol's coastal proximity and open terrain typically yield slightly cooler readings than inland urban areas. No regulatory barriers exist under German GlüStV or US CFTC frameworks for this contract, and the sub-$1,500 accessibility threshold under most no-KYC regimes applies to individual positions.

FAQ

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Polymarket Legal in Canada has a different geo footprint.

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Polymarket Legal in Canada stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
