Market context
Taipei’s July 2026 heatwave has cooled slightly in the last 48 hours, with mid-July highs dipping to 32–33°C instead of the typical 34°C peak, while humidity remains oppressive at 75–80% [6][10]. The 0% crowd-implied probability for any extreme high reflects this moderation: historical data shows July averages sit between 27–33°C, with only rare spikes above 37°C [6][9]. The highest ever recorded in Taipei was 39.3°C, but such extremes typically require sustained typhoon-free, cloudless conditions—currently absent as thunderstorms and cloud cover have interrupted sunshine [10].
Traders should monitor the weekly typhoon forecast and daily cloud-cover trends, as late-afternoon downpours regularly cap daytime highs in Taipei’s basin geography [10]. The key catalyst is the Wunderground daily report for RCSS on 20 July 2026, which will settle the market; any sudden shift to clear skies and high-pressure systems could push temperatures toward 35°C, though current forecasts suggest a stable 32°C peak [2][6]. With July 2026 already 0.9°C cooler than average, the probability of an extreme outlier remains negligible unless a rapid atmospheric change occurs [6].
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 Prediction Today, which mirrors the Polymarket order book directly.
Resolution & payout
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
