Market context
The market settles on the highest temperature recorded at Gimhae International Airport Station in Busan on 28 July 2026, measured in degrees Celsius. Resolution depends on historical weather data from Weather Underground, with the settlement window closing at 12:00 UTC on that date. The 0% crowd probability suggests either extreme confidence in a specific temperature band or insufficient liquidity to establish meaningful odds across the available ranges.
Busan's July climate is consistently hot and humid, with daily highs typically between 28–32°C during mid-to-late summer. Historical data from the Korea Meteorological Administration shows that extreme heat events—temperatures exceeding 35°C—occur sporadically but are not anomalous for the region. The 2018 heat wave saw Busan reach 34.5°C; comparable July readings from 2012–2022 cluster around 29–31°C. The current zero probability reading likely reflects either a narrow range selection or early-stage market formation rather than meteorological certainty.
Traders should monitor the Korean Meteorological Administration's extended forecasts as July 2026 approaches, particularly any alerts for heat waves or typhoon activity that could suppress temperatures. El Niño or La Niña conditions in the preceding months may influence regional pressure patterns. The settlement mechanism's reliance on a single airport station means localised weather variations—cloud cover, urban heat effects—become material; Gimhae Airport's coastal location can produce readings 1–2°C cooler than central Busan on clear days. No regulatory announcements or policy changes are expected to affect temperature measurement standards between now and settlement.

FAQ
- Is Polymarket legal in my country?
- Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Is Polymarket Legal in Canada has a different geo footprint.
- 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.
- How are winnings taxed?
- Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.
- 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.
- 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.
