Pronóstico: Highest temperature in Buenos Aires on July 18?

Platform comparison

Market context

On 18 July 2026, the highest temperature recorded at Minister Pistarini International Airport in Buenos Aires will fall into one of several defined ranges. The market currently prices all outcomes at 0% YES, reflecting either a technical settlement issue or extremely sparse liquidity on Polygon. Resolution depends on historical data from Wunderground's weather station at Ezeiza, with the settlement window closing at midday UTC on that date—a constraint that matters if intraday temperature swings occur late in the day.

Buenos Aires in mid-July sits in the Southern Hemisphere's winter, when daily highs typically range between 12°C and 17°C. Historical records from the same airport station show July temperatures rarely exceed 20°C; the coldest readings cluster around 8–10°C. This seasonal consistency means the market's outcome space is relatively narrow compared to summer months. Traders should reference Wunderground's historical daily records for Minister Pistarini to establish baseline expectations; the station's elevation and proximity to the Río de la Plata influence local microclimates.

No scheduled weather events or atmospheric anomalies are forecast for mid-July 2026 at this stage. Traders monitoring this contract should track long-range forecasts as the date approaches, particularly any unusual cold fronts or warm air masses moving across Argentina. The 0% pricing suggests either no conditional token liquidity has formed yet or the market has not attracted sufficient trader interest to establish meaningful price discovery on Polygon.

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.
