Highest temperature in Beijing on July 10?

Platform comparison

Market context

The market hinges on whether Beijing’s Capital International Airport will record a high temperature above 29°C on 10 July 2026, with the crowd currently pricing a 94% chance of a “YES” outcome. Historical data shows July is Beijing’s hottest month, with daily highs averaging around 31°C (88°F) and rarely dipping below 27°C (81°F). In 1959, the airport recorded 37°C on 10 July, while in 2001, 11 July saw 40°C. Even in cooler years, July 10 temperatures typically exceed 29°C, reinforcing the high probability implied by current market pricing[1][3][4].

Traders should monitor real-time weather updates from Wunderground, the official resolution source, as well as any sudden shifts in humidity or cloud cover that could suppress peak temperatures. Authorities have recently urged residents to limit outdoor exposure during heatwaves, citing record-breaking temperatures across northern China, including a 41.8°C spike in Beijing in 2023[2][7]. While no scheduled political debates or campaign-finance disclosures directly influence weather, broader climate policy announcements from Beijing’s municipal government could signal future heat mitigation efforts. The market is leaning on immediate meteorological data rather than political catalysts, with Reuters confirming China’s national average temperature hit a record in July 2024, underscoring the trend of intensifying summer heat[10].

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 Beijing on July 10? 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.

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.

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.
