On 10 May 2026, the highest temperature recorded at Esenboğa International Airport in Ankara will settle this market into one of several predefined ranges. The resolution will draw from Weather Underground's historical data for that specific date and location, capturing the daily maximum temperature in degrees Celsius. Settlement occurs at 12:00 UTC on the day itself, once the meteorological record is finalised.
Ankara's May temperatures typically range between 20–28°C, with historical data showing considerable year-to-year variation depending on spring weather patterns across central Anatolia. The 0% implied probability currently reflected in Polymarket's order book suggests traders are pricing in either extreme confidence in a specific temperature band or minimal liquidity across the full range of outcomes. May represents a transitional period between spring and early summer in the region, with occasional heat waves pushing temperatures above 30°C, though such events remain statistically less frequent than moderate conditions.
Traders monitoring this market should track Turkish meteorological forecasts released in early May, particularly any warnings from Turkey's State Meteorological Service regarding high-pressure systems or heat advisories for the central Anatolian plateau. Seasonal climate patterns—including the North Atlantic Oscillation's influence on Mediterranean weather systems—typically become clearer 7–10 days before settlement. The current zero probability across the order book may reflect thin initial trading rather than genuine market consensus, creating potential arbitrage opportunities as May approaches and forecasts crystallise.
The highest temperature recorded on Earth has been measured in three major ways: air, ground, and via satellite observation. Air measurements are used as the standard measurement due to persistent issues with unreliable ground and satellite readings. Air measurements are noted by the World Meteorological Organization (WMO) and Guinness World Records among ot

This market settles from the official outcome published at https://www.wunderground.com/history/daily/tr/%C3%A7ubuk/LTAC. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "Highest temperature in Ankara on May 10?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$79K in lifetime turnover and $0 of resting liquidity puts this market in the above the median by volume for weather contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $2K in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
