Highest temperature in Ankara on July 2?

Platform comparison

Market context

The underlying event is the peak daytime temperature recorded at Esenboğa International Airport on 2 July 2026, a date when Ankara typically experiences intense, dry heat with minimal rainfall. Long-term averages suggest a maximum of 29°C, yet recent meteorological data indicates temperatures often climb higher, frequently reaching 31°C to 33°C during mid-summer peaks[2][3]. The current crowd-implied probability of 0% for the "YES" outcome (likely a specific high threshold) appears starkly divergent from the volume-weighted odds on cross-platform markets, where 33°C commands the highest trading interest at £61.2K, followed closely by 31°C at £38.1K[1]. This discrepancy suggests the prediction market may be underpricing the likelihood of extreme heat compared to the consensus reflected in active sportsbook-style lines.

Traders should monitor the Turkish Meteorological Directorate’s (MGM) real-time forecasts for 2 July, as they have flagged "extreme temperatures peaking" for the capital on this specific date[9]. The primary catalyst is the absence of cloud cover and the dry conditions typical of July, which is Turkey’s driest month with only 17mm of average rainfall[3]. While the NATO summit in Ankara occurs later in the week (7–8 July), the atmospheric pressure systems driving that event may already be intensifying heat levels by 2 July[10]. No specific weather announcements are scheduled, but the lack of precipitation and the 12 hours of daily sunshine create a high-risk environment for temperatures exceeding the 29°C average, making the 0% probability line a significant outlier against historical and forecasted data[2].

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
