Pronóstico: Highest temperature in Beijing on June 30?

Platform comparison

Market context

On 30 June 2026, the Beijing Capital International Airport Station will record its peak daily temperature, which determines the settlement of a prediction market focused on whether that maximum falls within the 27–29 °C range. Current crowd-implied probability for this outcome sits at 0%, suggesting traders expect a significantly higher or lower extreme.

Historical June climatology in Beijing typically shows daily maxima near 30 °C, with daytime averages reaching 30 °C and overnight lows around 19 °C [3]. Recent Polymarket data confirms this pattern: on 25 June, the highest temperature hit 32 °C [2], while on 29 June, the market settled at 27 °C [1]. A record-breaking heatwave earlier in the month saw temperatures reach 106 °F (41.1 °C), shattering June records [8]. These comparable cases indicate that while 27–29 °C is plausible, the 0% probability likely reflects expectations of either a hotter spike or a cooler dip due to variability.

Traders should monitor daily weather forecasts from AccuWeather for the Beijing Capital International Airport, which project daily highs between 82° and 93°F (27.8°–33.9°C) for June 2026 [4]. Key catalysts include sudden shifts in precipitation, as June brings about 114mm of rain and occasional windy or dust storm days that can temporarily lower temperatures [3]. Any official announcements regarding heatwave warnings or unusual cloud cover from Wunderground’s real-time data will directly impact the final settlement value [1].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
