Highest temperature in NYC on August 2?

Platform comparison

Market context

The key event is the day’s maximum temperature at LaGuardia Airport, which is usually driven by the broader New York metro weather setup rather than any political or campaign development. Wunderground is the settlement source, and its history page is already showing an **83°F** daily high for LaGuardia, which sits in the middle of a fairly normal August range rather than an extreme-heat regime.[2]

For context, New York’s early-August highs often land in the low to mid-80s, and the current market pricing appears more consistent with that climatology than with a record-chasing spike. AccuWeather’s monthly view shows recent and nearby highs clustered around the low-to-upper 80s, while Wunderground’s daily history for the date indicates 83°F, suggesting the market is leaning on an ordinary summer profile rather than a severe-heat analogue.[1][2]

The main catalyst a trader should watch is the short-term forecast and any last-minute changes in cloud cover, humidity, wind, or storm timing, because these factors can shift the realised high by a few degrees even on otherwise similar days. There is no obvious election-style announcement or scheduled political event to anchor this market; instead, the decisive inputs are weather model updates and how close the afternoon temperature gets to the airport station’s observed maximum, with recent New York heat reporting from major outlets underscoring how quickly the city can swing from moderate to exceptional in summer.[4][9]

With a clearly defined outcome the USDC payout lands within minutes of the final confirmation.

FAQ

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
