Highest temperature in Wellington on July 9?

Platform comparison

Market context

The real-world event is the daily high temperature at Wellington International Airport on 9 July 2026, with current crowd-implied probability of 0% for any outcome above the lowest range. Historical data shows July is Wellington’s coldest month, with average lows near 47°F (4°C) and typical highs rarely exceeding 15°C (59°F), as confirmed by long-term climate records for the station[4]. Comparable cases from July 2024 and prior years show consistent cool, wet conditions with strong south-westerly winds, making extreme warmth highly improbable and aligning with the market’s near-zero pricing for higher ranges[9].

Traders should monitor real-time updates from Wunderground and the National Weather Service for any anomalous shifts, though current forecasts predict strong winds and rain with a high of 52°F (11°C) for the day[2]. The market leans heavily on the absence of any heatwave catalysts—no scheduled climate declarations, campaign-finance disclosures, or political debates are expected to influence weather patterns in Wellington this week. Recent news from the BBC confirms persistent cool conditions with no deviation from seasonal norms, reinforcing the 0% probability for higher temperature outcomes[2].

FAQ

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

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.
