Highest temperature in Amsterdam on August 15?

Platform comparison

Market context

On 15 August 2026, the highest temperature recorded at Amsterdam Airport Schiphol Station will determine the settlement outcome for this market. The 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 current crowd probability of 0% suggests traders are either awaiting specific temperature thresholds to be defined or treating the market as nascent pending clarification of the exact range brackets.

Historical August temperatures in Amsterdam cluster between 18–24°C on average, with occasional peaks above 25°C during heat waves. The summer of 2022 saw multiple days exceed 30°C across the Netherlands, whilst 2021 remained cooler. The 0% reading reflects uncertainty about which temperature bands the market will ultimately offer as settlement options rather than scepticism about the event itself occurring. Comparable weather markets on this platform have typically seen probability mass concentrate once range definitions are published.

Regulatory accessibility for this market varies by jurisdiction. Under German GlüStV rules, prediction markets on weather events fall outside gaming licensing if they meet information-market criteria, though operators must register with BaFin. US CFTC oversight applies to derivatives on weather indices, though non-leveraged prediction markets under $1,500 notional exposure per trader often operate in a grey zone. The "no-KYC up to $1,500" threshold means traders in certain jurisdictions can participate without identity verification provided their position size remains modest, though this does not override underlying regulatory obligations in their home territory.

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 Kalshi Legal in California has a different geo footprint.

Do I need to KYC for Is Kalshi Legal in California?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

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).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Kalshi Legal in California would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
