Highest temperature in Lucknow on July 7?

Platform comparison

Market context

The real-world event driving this market is the peak daily temperature recorded at Chaudhary Charan Singh International Airport in Lucknow on 7 July 2026, measured in degrees Celsius. Current crowd-implied probability sits at 0% for a specific outcome, yet historical patterns suggest this figure may be misleading if interpreted without context. In July, Lucknow’s daily highs typically decrease by 5°F, ranging from 96°F down to 91°F, rarely dipping below 85°F or exceeding 103°F[1]. Recent data shows the highest temperature in the preceding fortnight reached 105.8°F on 26 June 2026[3], while the city’s all-time seasonal peak hit 47.8°C on 12 June 2025[5]. A recent report noted a maximum of 43.4°C at the Amausa observatory, four degrees above normal, indicating active heat anomalies this season[6].

For a power-user approaching this programmatically, the key catalyst is the Wunderground daily maximum feed, which resolves the market by capturing the highest temperature recorded for all times on that day. Traders should monitor real-time weather updates from the India Meteorological Department and cross-reference with AQI.in’s historical extremes to validate conditional order triggers[5]. The settlement depends entirely on the Wunderground dataset for Chaudhary Charan Singh Airport, so any discrepancy between local observatory readings and this station’s data could shift probabilities rapidly[4]. Given the 1-in-3 chance priced for 33°C in related markets, a script should flag deviations above 35°C as high-probability settlement zones[2]. No moralising is needed; the facts show that July heat in Lucknow is volatile, and the 0% probability likely reflects a narrow range definition rather than an absence of heat.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.

Do I need to KYC for this market?

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