Highest temperature in Hong Kong on July 11?

Platform comparison

Market context

Hong Kong is set to experience typical midsummer heat on 11 July 2026, with forecasts from the Hong Kong Observatory and climate models indicating a maximum temperature between 32°C and 35°C[1][10]. The current crowd-implied probability of 0% for a YES outcome appears misaligned with these projections, as the market’s frontrunner is the 34°C range at 40%, followed closely by 35°C at 27%[1]. This suggests traders are pricing in a high likelihood of temperatures reaching the upper end of the seasonal norm rather than an absence of heat.

Historically, July and August are Hong Kong’s hottest months, with average temperatures hovering around 32°C and frequent peaks reaching 35°C or higher due to climate warming trends[4][5]. The Observatory’s seasonal forecast for July–September 2026 explicitly predicts normal to above-normal temperatures, reinforcing the expectation of intense heat[4]. Comparable cases from recent years show that daily maximums in early July often exceed 33°C, making a 0% probability for significant heat statistically anomalous given the long-term warming trajectory.

Traders should monitor the Hong Kong Observatory’s “Daily Extract” for the finalized “Absolute Daily Max (deg. C)” once published, as this is the sole resolution source[1]. The market leans on the official observational data rather than model forecasts, meaning any deviation from the 32–35°C range would only be confirmed post-settlement. Recent weather updates from the Southern China Morning Post note temperatures hitting 35°C on similar dates, underscoring the plausibility of the 34–35°C outcomes currently favoured by the market[7].

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.

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 Election Predictions UK 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.

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.
