Market context

On 7 June 2026, the highest temperature recorded at LaGuardia Airport will settle this market into one of several defined ranges. The settlement uses Wunderground's historical weather data for that specific station, measured in Fahrenheit, with the market resolving to whichever bracket contains the peak daily reading. The 0% crowd probability suggests either extreme confidence in a particular outcome or minimal liquidity and trader participation at present.

New York's early June climate typically ranges between 70–85°F, with occasional heat waves pushing into the low 90s. Historical June 7th data shows considerable variance: the city has recorded highs as low as 68°F and as high as 91°F on this calendar date across different years. The current nil probability likely reflects either a very narrow range being offered as the YES option, or traders waiting for closer-to-event pricing before committing capital. Comparing platforms, Polymarket displays implied probabilities directly whilst Kalshi uses decimal odds; both charge different fee structures (Polymarket's 2% taker fee versus Kalshi's variable maker/taker model), which affects breakeven thresholds on weather markets where historical distributions are well-documented.

The National Weather Service issues extended forecasts roughly 10–14 days before the event, with meaningful updates arriving in the final week of May 2026. Seasonal patterns—including Atlantic tropical systems, high-pressure systems, and urban heat island effects specific to the LaGuardia area—will shape actual conditions. Traders should monitor late-May meteorological outlooks and compare settlement mechanics across platforms, as Smarkets and Betfair may offer alternative temperature brackets or different closing times that affect final readings.

Methodology

We read Highest temperature in NYC on June 7? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live quote comes directly from the Polygon order book; the other three are listed with their platform attributes — fees, KYC, settlement currency, payment options — because a 1:1 contract comparison without API access would be guesswork.

Resolution & payout

Settlement is the biggest difference between the four platforms: Polymarket on-chain in USDC (instant), Kalshi USD via CFTC (T+1), Betfair and Smarkets in local currency via bank withdrawal (T+1 to T+3). Kalshi Alternative UK routes every trade directly into Polymarket's on-chain settlement, which is why payouts land fastest.
