Market context
On 14 August 2026, the highest temperature recorded at Guangzhou Baiyun International Airport will determine this market's outcome. Resolution depends on the Daily Observations table from Weather Underground rather than the Day High & Low summary, a distinction that matters when station equipment logs micro-variations or when display rounding differs from raw sensor data. Guangzhou's August climate typically peaks between 32–35°C, though extreme heat events have pushed readings toward 37–38°C in recent summers.
Historical August temperatures at Baiyun Airport show the city rarely exceeds 36°C on any single day, making extreme-heat ranges statistically unlikely. The 0% crowd probability reflects baseline expectations: most August days in Guangzhou settle within the 33–35°C band. However, tropical systems, urban heat-island effects, and timing of afternoon peak readings can shift outcomes. Comparable markets on Guangzhou summer temperatures have resolved across the full range when monsoon patterns or heat domes arrive unexpectedly.
Traders should monitor China Meteorological Administration forecasts released in early August and any tropical cyclone activity in the South China Sea during the second week of the month. Typhoon season peaks in August, and even systems tracking away from Guangzhou can alter atmospheric pressure and cloud cover, suppressing or amplifying daily highs. Weather Underground's station data updates hourly; final resolution uses observations through the settlement window closing at 12:00 UTC on 14 August 2026. No regulatory KYC thresholds affect this market's accessibility across jurisdictions; the underlying event is purely meteorological.

FAQ
- Do I need to KYC for Is Polymarket Legal in Canada?
- Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.
- Can I trade anonymously?
- Pseudonymously, yes — up to the KYC threshold. Is Polymarket Legal in Canada stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.
- Are prediction markets gambling?
- Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.
- Is there a withdrawal cap?
- No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).
- What if regulation changes?
- If regulation changes in your jurisdiction (e.g. prediction markets are banned), Is Polymarket Legal in Canada would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
