Highest temperature in Shenzhen on July 6?

Platform comparison

Market context

The underlying real-world event is the highest temperature recorded at Shenzhen Bao’an International Airport on 6 July 2026, measured in degrees Celsius. Historical data shows that mid-July in Shenzhen typically sees daily highs around 32–34°C, with 6 July specifically averaging 33°C [1]. Last year, the peak reached 33°C on 6 July, and the monthly maximum for July has consistently stayed near 32–34°C across recent years [1][6]. Given that 0% is the current crowd-implied probability for a “YES” outcome (likely meaning a temperature above a specific threshold, perhaps 35°C), this aligns with the fact that temperatures exceeding 35°C are rare in Shenzhen during this period, occurring only under extreme subtropical high pressure or typhoon-related anomalies [1].

Traders should monitor the subtropical high pressure system’s positioning and any incoming typhoon forecasts, as these are the primary catalysts for temperature spikes. The China Meteorological Administration has recently issued alerts for prolonged heatwaves in southern China, with 578 observatories recording new highs for the period [8]. Additionally, Wunderground’s hourly data for the Bao’an station will be the official resolution source, so real-time updates from that platform are critical [9]. While no official announcement has yet confirmed a record-breaking day, the combination of high humidity (79%) and 17 rainy days in July suggests that sudden heavy showers could temporarily suppress temperatures, making a 35°C+ event even less probable [1].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi UK, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
