Highest temperature in Taipei on July 13?

Platform comparison

Market context

Taipei Songshan Airport will record its peak temperature for 13 July 2026, with settlement based on the highest Celsius reading at the station via Wunderground. The current crowd-implied probability of 0% YES suggests the market expects the temperature to fall outside the specific range offered, likely due to prevailing overcast conditions and moderate precipitation chances forecast for the morning, which typically suppress peak highs [3][5].

Historically, July is Taipei’s hottest month, with average highs reaching 92°F (32°C) and record extremes far exceeding typical summer levels, such as the 39.7°C peak recorded in 2020—the highest in 124 years [2][4]. The warmest low temperature ever recorded on 13 July at Songshan was 32.0°C in 2014, indicating that even overnight lows can approach the upper bounds of many temperature ranges, making a 0% probability unusual unless the offered range is implausibly low [1].

Traders should monitor real-time updates from the Central Weather Administration and Wunderground history pages as the day progresses, since thunderstorms expected overnight into Sunday could clear by afternoon, potentially allowing temperatures to peak near 97°F (36.1°C) [5]. The settlement depends entirely on the single highest reading across all 24 hours, meaning a brief afternoon heat spike after cloud cover dissipates could override morning overcast suppression [3]. No crypto macro events directly influence this weather contract, but USDC settlement and on-chain liquidity on btc-prediction.bet will determine execution speed once the 2026-07-13T12:00:00Z window closes.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.

FAQ

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

How does UMA secure the resolution?

The UMA Optimistic Oracle uses a bond system: a proposer posts a bond, a two-hour challenge window opens. On dispute the losing side forfeits the bond — financial incentive for honest resolution.

How volatile are crypto prediction markets?

Crypto markets react to spot prices — a 5% BTC move typically shifts a "BTC above X by date" market 10-20%. Polymarket crypto market liquidity is usually six-figure USD, sufficient for active trading.

Which crypto markets exist on Polymarket?

Currently active markets include BTC/ETH/SOL price targets, halving dates, ETF approvals, hard-fork outcomes and Layer-2 TVL thresholds. The list updates weekly; biggest volume sits on BTC and ETH price forecasts.
