Highest temperature in Chengdu on July 11?

Platform comparison

Market context

Chengdu Shuangliu International Airport will record its peak daily temperature on 11 July 2026, with the market resolving to the Celsius range containing that high. Historical July climatology for the Sichuan Basin places average daily maxima near 30–32°C, though recent years show more frequent readings above 35°C due to humidity and monsoon influences [3]. Current trader consensus on comparable Polymarket events clusters around 32–34°C, with 34°C leading at 27% and 35°C following at 22%, suggesting the 0% YES probability for the current market likely reflects a mismatched range definition rather than an expectation of cold conditions [2].

Traders should monitor real-time meteorological updates from Wunderground, the designated resolution source, as ensemble spreads in global models remain tight amid midsummer conditions [2]. Key catalysts include daily forecast revisions from Yr and AccuWeather, which currently indicate maximums near 38°C with light rain showers possible, alongside humidity levels that can cap extreme heat despite high temperatures [4][6]. While crypto macro factors like BTC funding rates or whale flows do not directly influence weather outcomes, USDC settlement mechanics on btc-prediction.bet ensure on-chain transparency for this weather contract, aligning with the platform’s focus on verifiable, non-financial event resolution.

Methodology

This page reads Highest temperature in Chengdu on July 11? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement.

Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

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.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

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.

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.
