Highest temperature in San Francisco on August 5?

Platform comparison

Market context

The real-world event is the highest temperature recorded at San Francisco International Airport on 5 August, measured in Fahrenheit and ultimately taken from the Wunderground daily history page for KSFO. In practice, this is a narrow airport-observation question rather than a citywide weather call, so the relevant reference point is the official station high on the day, not conditions elsewhere in San Francisco.[3][11]

The current 0% YES pricing is hard to reconcile with the city’s climate baseline: August highs in San Francisco are typically around the upper 60s to low 70s Fahrenheit, with marine influence often keeping daytime temperatures subdued. Comparable market pricing elsewhere has also centred on the low-70s band, with one live listing showing the main probability mass around 72–73°F and 74–75°F as the next bucket, which is consistent with a normal coastal summer rather than an extreme heat setup.[2][10][15] The main legal-access frame is that German GlüStV restrictions can materially limit participation from German users even when the underlying event is straightforward, while US CFTC reach matters because some prediction-market activity sits within a broader US regulatory perimeter rather than ordinary sports-style wagering.[13]

For accessibility, “no-KYC up to $1,500” means a user can usually trade or hold positions below that threshold without completing full identity verification, but the exemption is capped and platform-specific, so it does not remove the underlying geo, sanctions, or eligibility screening. Traders should watch for late-afternoon station updates, any revisions to Wunderground’s history feed, and the point at which the next day’s first datapoint is published, because market rules typically freeze the settling observation once that boundary is crossed; in warmer Pacific setups, the only material upside risk comes from a stronger-than-expected marine layer breakdown or inland flow, not from a major forecast regime shift.[2][3]

FAQ

How are winnings taxed?

Tax treatment varies by jurisdiction. In most countries, prediction market gains are treated as ordinary income or capital gains. We cannot provide tax advice — consult a tax professional for your specific situation.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Germany Legal exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Are prediction markets gambling?

Legally unclear in most jurisdictions. Some interpretations classify them as wagering (gambling regulation applies), others as derivatives (financial regulation applies). There's no global precedent specifically for on-chain prediction markets.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Germany Legal would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
