Highest temperature in Lucknow on July 7?

Platform comparison

Market context

On 7 July 2026, the Chaudhary Charan Singh International Airport in Lucknow will record its peak temperature for the day, a real-world event that determines the outcome of a prediction market where the crowd currently assigns zero probability to a 33°C outcome. This stark divergence from other platforms, such as Lines.com, which prices a roughly one-in-three chance for exactly 33°C, highlights a significant misalignment between sportsbook-style odds and prediction-market implied probabilities. While the crowd on this contract dismisses the lower temperature band entirely, historical data suggests July highs in Lucknow typically decrease from 96°F to 91°F, rarely falling below 85°F or exceeding 103°F, making the 33°C threshold (approximately 91.4°F) a plausible, if not guaranteed, ceiling for the day [1].

Traders should monitor the immediate progression of the monsoon season and any sudden shifts in cloud cover, as these are the primary catalysts that could suppress temperatures below the 33°C mark. Recent reports indicate Lucknow recorded its hottest day of the season so far on a Saturday, with the Met observatory in Amausi reaching 43.4°C, four degrees above normal, suggesting a trend of elevated heat that contradicts the zero-probability stance on lower bands [7]. Furthermore, the highest temperature recorded in the preceding fifteen days was 105.8°F on 26 June 2026, reinforcing the likelihood of sustained high heat rather than a sharp drop to 33°C [4]. Analyst consensus across platforms appears to favour higher temperature ranges, creating a clear opportunity to assess whether the zero-probability line represents a genuine market correction or an error in pricing logic.

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 Kalshi vs Polymarket. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
