Highest temperature in San Francisco on July 12?

Platform comparison

Market context

San Francisco’s July 12, 2026 high temperature will be measured at the San Francisco International Airport (KSFO), with resolution based on Wunderground’s daily record. Historical July data shows mean highs near 72°F, with typical variability of 4–6°F, making extreme outliers uncommon but not impossible [2][4]. The current crowd-implied probability of 0% for any specific “YES” outcome likely reflects a fragmented market where no single temperature band dominates, rather than a belief that the event won’t occur; comparable markets for July 9 and July 13 show leading bands at 68–69°F (37.5%) and 78–79°F (50%) respectively, underscoring how July heat in SF can swing sharply day-to-day [1][3][4].

Traders should monitor the National Weather Service’s daily climatological reports issued by SFO, which publish official KSFO records shortly after each day closes, and watch for any heat-advisory announcements from NWS that could signal above-normal highs [7][8]. While no specific catalyst is scheduled for July 12, regional weather models updated daily by AccuWeather forecast July 2026 highs between 67°F and 79°F at KSFO, providing a practical range for outcome expectations [2]. The market’s 0% implied probability for a single outcome suggests liquidity is spread across multiple bands, with 72–73°F (30%) and 70–71°F (25%) as current frontrunners [3].

Regulatory access hinges on jurisdiction: German GlüStV rules may restrict participation for residents unless the platform holds a state licence, while US CFTC reach applies if the market is deemed a futures contract, though prediction markets often operate under a different framework. The “no-KYC up to $1,500” threshold means users can trade this weather market without identity verification below that limit, enhancing accessibility for casual traders, but larger positions will require full KYC compliance regardless of jurisdiction.

FAQ

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 Legal UK has a different geo footprint.

Do I need to KYC for Polymarket Legal 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.

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.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal 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.

What happens during a tax audit?

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