Highest temperature in Chongqing on July 27?

Platform comparison

Market context

Chongqing’s weather on 27 July is normally driven by the city’s summer heat and monsoon humidity, with July averages around 33°C for the high and frequent rain or thunderstorms layered on top.[1][2] That makes the contest less about a single fixed forecast and more about whether the afternoon peak at Chongqing Jiangbei International Airport lands in the upper 30s or gets clipped by cloud cover and shower activity.

For framing, the market is leaning on the broader seasonal pattern rather than a one-day event calendar: Chongqing’s rainy season runs from May to September, and July is typically the hottest, wettest part of the year.[2][4] Travel guides for the city put typical July daytime temperatures in the mid-30s Celsius, while market pricing is currently concentrated in the 38°C-39°C band, suggesting traders expect at least one strong heat spike even if the exact airport reading is volatile.[1][3]

The main catalyst to watch is the local weather evolution through the daytime warming cycle rather than any scheduled announcement, since the settlement source is the daily high recorded at the airport station on Wunderground.[3] In practical terms, traders will be watching for changes in cloud cover, rainfall timing and thunderstorm development, because Chongqing’s July climate is described as humid, rainy and prone to heavy thunderstorms, all of which can suppress the eventual maximum temperature.[1][2]

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Highest temperature in Chongqing on July 27? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

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.

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.

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.

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.
