Highest temperature in Beijing on July 13?

Platform comparison

Market context

Beijing’s highest temperature on 13 July 2026 will be measured in degrees Celsius at the Beijing Capital International Airport Station, with settlement determined by Wunderground’s daily record. The crowd-implied probability of 0% YES suggests traders expect the peak to fall outside the market’s defined range, though July is historically Beijing’s hottest month, averaging a high of 31.1°C (88°F) with frequent spikes above 35°C [5]. In 2023, July temperatures reached 40°C, and the city’s all-time record of 41.9°C was set on 24 July 1999, while some datasets cite a 42.1°C peak on 5 July 2010 [1][3][9]. These comparable extremes indicate that a 0% probability may understate the likelihood of a heatwave, especially as mid-July often delivers the year’s most intense solar heating.

Traders should monitor the China Meteorological Administration’s daily forecasts and real-time Wunderground updates for the ZBAA station, as heatwaves in Beijing are frequently driven by southerly airflow and high humidity that amplify perceived and recorded temperatures [1]. Recent reports from June 2023 noted Beijing soaring above 41°C, prompting authorities to urge outdoor limits, signalling that official warnings often precede record-breaking days [2]. On-chain, the market settles in USDC with resolution tied to a fixed UTC window ending 12:00 on 13 July 2026; any BTC or ETH volatility around that time could influence whale positioning, though weather contracts typically remain uncorrelated with crypto macro unless funding rates shift sharply. Watch for sudden announcements from Chinese climate agencies, as policy responses to extreme heat can accelerate temperature spikes.

Methodology

This page reads Highest temperature in Beijing on July 13? on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. 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

What are crypto prediction markets?

Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.

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.

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.

Are crypto prediction markets taxable in the US?

In the US, prediction market gains are typically treated as ordinary income or short-term capital gains depending on holding period. Consult a tax professional for your specific situation — we cannot provide tax advice.
