Highest temperature in Lucknow on July 7?

Platform comparison

Market context

The real-world event at hand is the peak temperature recorded at Chaudhary Charan Singh International Airport in Lucknow on 7 July 2026, with the market currently pricing a 0% chance that the high will reach 33°C. This near-zero probability starkly contrasts with historical July patterns, where Lucknow routinely sees highs between 36°C and 41°C, as confirmed by AccuWeather’s monthly forecast showing daily highs from 86°F to 93°F [4] and WorldWeatherAI noting 7 July as the warmest day at +41°C [9]. The Indian Meteorological Department’s press note from 6 July recorded a maximum of 36.5°C, already 1.6°C above normal, suggesting that 33°C is far too low for this season [5].

Traders should monitor immediate weather updates, particularly the 66% probability of patchy rain forecast for 8 July, which could suppress temperatures slightly but not to 33°C levels [1]. Recent weather bulletins indicate heavy rain and thunderstorms may begin between 8–10 July across Uttar Pradesh, potentially affecting Lucknow’s heat profile, though daytime highs are still expected to reach 37–38°C [3]. On-chain, the contract settles via USDC on Polygon using conditional tokens, meaning liquidity and price movements will reflect real-time shifts in Wunderground’s official temperature data for the airport station. No structural catalysts suggest a drop to 33°C; the prevailing meteorological trend points firmly toward significantly higher temperatures.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is PolyGram. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
