Highest temperature in Tokyo on July 27?

Platform comparison

Market context

Tokyo’s midday heat on 27 July will be set against a forecast that points to a warm but not extreme day, with the city expected to reach **33°C** and showers or thunderstorms possible later in the day.[1] That matters because this market settles on the *highest* temperature recorded at Tokyo Haneda Airport Station, so a forecast high in the low 30s keeps the outcome clustered around the upper-end summer range rather than the hottest extremes seen during stronger heatwaves.[1][3]

Seasonally, late July in Tokyo usually sits near its summer peak, but the distribution is broad: average July daily highs are around the mid-to-upper 20s °C, while typical daytime maxima often reach the low-to-mid 30s °C.[2][3][4] In that context, a reading around 33°C is consistent with a normal hot-summer outcome rather than a rare spike, which helps explain why a **0% YES** price can persist if the market’s YES band requires something materially above the forecasted range.[2][3]

For traders, the main catalyst is the day’s **official airport observation** rather than citywide averages, so the key question is whether clearing, sunshine, or local heating briefly lifts Haneda above the forecast headline before cloud, rain, or sea-breeze effects cap temperatures.[1] FNN’s morning forecast for Tokyo leaves room for instability later, with clouds, sunshine, and some evening rain or thunder noted, which leans the market towards a contained peak rather than a late-session surge.[1]

FAQ

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.

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.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
