Highest temperature in NYC on August 6?

Platform comparison

Market context

New York City’s late-summer heat is the real-world driver here, with the market settling on the day’s highest reading at LaGuardia rather than a citywide average. Current public forecasts for 6 August point to an upper-80s to near-90s Celsius-free high range for New York, while a heat advisory has been in place for the metro area and local reporting has described dangerous heat and humidity with “feels like” values above the actual air temperature.[3][10][15]

The 0% implied probability should be read against both the forecast and the contract design. LaGuardia often runs a little cooler or warmer than Central Park depending on wind and sea-breeze effects, but a top-end outcome in the forecast band is still plausible in August, when daily highs in New York commonly sit in the low-to-mid 80s Fahrenheit and can push into the 90s on hotter days.[15] For context, similar weather markets on the same date have been priced well above zero on other venues, including a Robinhood temperature market showing 75¢ for an 88°F outcome bucket at the time of capture.[7]

On accessibility, the regulatory overlay matters as much as the weather. A German user-facing venue can be affected by the GlüStV framework if the activity is viewed as gambling-linked rather than pure financial speculation, while the US CFTC’s reach is relevant whenever a product is deemed a derivatives-style contract offered to US persons.[1] “No-KYC up to $1,500” usually means a smaller account can trade or withdraw within that cumulative ceiling before identity checks are triggered, which makes the market easier to access but does not remove tax, source-of-funds, or residency restrictions where they apply.[1]

UK Frequently Asked Questions

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.

No. Polymarket is not licensed by the UK Gambling Commission (UKGC). It is a decentralised prediction market operated under US regulation. UK traders can use it but do not benefit from UKGC dispute resolution or player protection requirements.

What are the HMRC tax rules on Polymarket profits for UK traders?

Polymarket profits are treated as cryptocurrency disposal events by HMRC. Each USDC settlement is a taxable event subject to Capital Gains Tax (CGT).
