Highest temperature in NYC on July 30?

Platform comparison

Market context

New York City’s hottest reading for 30 July 2026 will be set by the LaGuardia Airport station, so the market is really a bet on the day’s peak airport observation rather than a citywide average. The current 0% crowd-implied chance of a YES outcome points to traders expecting a maximum outside the market’s target range, despite late-July heat normally being the period when Manhattan and nearby borough stations are most likely to spike. Historical context matters here: New York’s all-time extremes are rare, and even in strong summer heat the city often tops out in the 80s or low 90s rather than producing a truly exceptional reading.[3][6][14]

Comparable weather markets tend to be decided by the difference between headline heat and the exact station used for settlement. That distinction is important because LaGuardia can run hotter or cooler than Central Park depending on sea breeze, cloud cover, and local wind shifts, while the settlement uses the station’s highest recorded temperature on the day, not a forecast or a citywide shorthand. Recent coverage showed New York briefly returning to 100°F in early July, with the National Weather Service recording Central Park at 100°F for the first time since 2012, underlining that short-lived spikes are possible even when the broader seasonal climate is less dramatic.[16][17]

For traders, the key catalysts are the day’s forecast updates, any heat advisories, and the timing of afternoon peak warming, which in summer often arrives after midday and can move the settlement result late in the session. The market closes at 12:00 UTC on 30 July, but the reported daily high on Wunderground can still be influenced by later official observations that become available after the settlement window, so the live weather setup into the afternoon is the main variable to watch.[4][5]

FAQ

Which entertainment markets are available?

Oscars / Academy Awards (Best Picture, Best Director, Best Actor/Actress), Eurovision Song Contest, Emmy Awards, Grammy Awards, Golden Globes, plus reality-TV outcomes (Bachelor, Survivor). Volume usually sits in the five- to six-figure range per market.

What was the top Oscar 2025 market?

Best Picture, with ~$2.8M volume on Polymarket. "Anora" started as an underdog at ~8% and closed at ~62% before the ceremony — the biggest single Oscar market swing since 2019.

Who can trade Eurovision markets?

Polymarket is globally accessible but geo-blocked in select jurisdictions — traders there use broker frontends with a different geo footprint to reach the order book. Eurovision markets have strong European liquidity; German/Austrian/Swiss flow often drives consensus.

How are reality-TV outcomes verified?

UMA Oracle uses the official show website or producer statement as the resolution source. Very narrowly defined markets (e.g. "Will X be voted off the island?") rely on the official show notes.

Are there politics-entertainment crossover markets?

Yes — e.g. "Will X be parodied on SNL?", "Who will host the next Oscars?". These have thinner liquidity but offer alpha for traders who read pop-culture and political worlds together.
