Highest temperature in San Francisco on July 12?

Platform comparison

Market context

San Francisco’s highest temperature on 12 July 2026 will be recorded at the San Francisco International Airport Station (KSFO), with resolution based on Wunderground’s daily high. The market currently shows 0% implied probability for any YES outcome, suggesting the crowd expects the temperature to fall outside the listed range, though the specific range is not disclosed here. Historical July highs at KSFO typically span 67°F to 79°F, with recent 2026 data showing daily peaks between 68°F and 79°F in early July [2][9]. Comparable prediction markets, such as the July 9 2026 SF high temp event, show fragmented probability distributions where mid-range bands like 68–69°F hold leading implied probabilities (37.5%), indicating how traders weigh moderate outcomes against outliers [1].

Traders should monitor the National Weather Service’s daily climatological reports for KSFO, issued each morning, which include climate normals and record highs that frame expectations for extreme heat events [7][8]. While no immediate heatwave announcements have been made for mid-July 2026, the AccuWeather July forecast for KSFO notes a potential upper bound of 79°F, a threshold that could trigger re-pricing if exceeded [2]. Accessibility hinges on regulatory framing: under Germany’s GlüStV, prediction markets face strict licensing, whereas US CFTC reach remains limited to commodity-linked bets. The “no-KYC up to $1,500” clause allows UK and EU users to access this weather market without identity verification, provided they stay under the threshold, enhancing liquidity for small-scale traders while avoiding full KYC burdens.

FAQ

Do I need to KYC for Polymarket Tax UK?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Tax UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

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 Tax UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
