Highest temperature in Tokyo on July 14?

Platform comparison

Market context

On 14 July 2026, Tokyo's highest temperature will be recorded at Haneda Airport Station and sorted into one of several defined ranges. The settlement depends entirely on historical weather data from Wunderground, with the measurement window closing at midday UTC on that date. This is a straightforward meteorological event with no political dimension, though temperature records do inform climate policy discussions and infrastructure planning across Japan.

Tokyo's July temperatures have historically ranged between 28°C and 37°C, with extreme heat events becoming more frequent in recent decades. The Japan Meteorological Agency's records show that mid-July typically experiences peak summer heat, with 2023 seeing temperatures exceed 35°C on multiple days. The 0% crowd probability suggests traders are either uncertain about the market mechanics or have not yet engaged with this weather-based contract. Comparable temperature markets on other platforms show meaningful trading activity when settlement criteria are transparent and historical baselines are established.

Traders should monitor Japan's seasonal weather forecasts as July 2026 approaches, particularly any alerts from the Japan Meteorological Agency regarding heat waves or unusual atmospheric patterns. Long-range forecasts become more reliable within two weeks of the settlement date. The specific choice of Haneda Airport Station as the measurement point matters, as urban heat island effects can create localised variations across Tokyo's metropolitan area. Wunderground's historical data archive will be the definitive source, making familiarity with that platform's interface essential for accurate settlement interpretation.

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.

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.
