Highest temperature in Madrid on July 12?

Platform comparison

Market context

The underlying event is the peak temperature recorded at Madrid-Barajas Airport on 12 July 2026, a date falling within Spain’s confirmed 2026 heatwave season. Current crowd-implied probability of 0% YES suggests traders expect the temperature to fall outside the market’s defined range, likely due to recent extreme readings pushing expectations higher. Historical context shows Madrid hit 42°C on 5–6 July 2026, with authorities warning heat would persist above 40°C until at least 7 July [2][4]. The first half of 2026 was Spain’s hottest ever recorded, with temperatures 1.6°C above normal, reinforcing the likelihood of sustained extremes through mid-July [10].

Traders should monitor daily Wunderground updates for Barajas Airport and regional alert levels from Spain’s meteorological agency, as nine regions were already on extreme heat alert by 4 July [7]. The settlement window closes at 12:00 UTC on 12 July, meaning any late-day temperature spike could alter resolution. Regulatory accessibility hinges on jurisdiction: German GlüStV may restrict access for residents, while US CFTC reach could apply if the platform offers contracts to US persons. The ‘no-KYC up to $1,500’ threshold allows anonymous participation below that limit, enhancing accessibility for this weather-specific market without triggering full identity verification, provided local laws permit such activity.

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.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Tax UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

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).
