Highest temperature in Helsinki on July 13?

Platform comparison

Market context

The market assesses the peak temperature recorded at Helsinki Vantaa Airport on 13 July 2026, with the crowd currently assigning zero probability to any specific outcome resolving as a definitive “YES” in isolation, though the frontrunner for the actual temperature is 23°C at 47% probability [1]. This 0% figure reflects the binary nature of the user’s view rather than the market’s actual distribution across the full range of possible temperatures, where 23°C dominates and 24°C follows at 22% [1].

Historical July highs in Helsinki typically cluster between 18°C and 26°C, with 23°C representing a common mid-range peak for the month rather than an extreme outlier. The current weighting toward 23°C aligns with long-term averages for the region, suggesting the market is leaning on climatological baselines rather than a specific weather anomaly or forecasted heatwave.

Traders should monitor real-time updates from Wunderground, the designated resolution source, which publishes the daily highest temperature for Helsinki Vantaa Airport [1]. Since the settlement window closes at 12:00 UTC on 13 July 2026, the final data point will be locked in shortly after the current time, making immediate weather observations the primary catalyst. No political debates, campaign disclosures, or scheduled conventions influence this weather market; the sole dependency is the recorded temperature at the airport station [1].

FAQ

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 Election Predictions UK 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.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

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.
