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, with resolution based on Wunderground’s daily high for that date. Historical July data shows typical highs between 67°F and 79°F at KSFO, with the warmest average day reaching 72.3°F [2][9]. The current 0% YES crowd-implied probability suggests traders expect the outcome to fall outside the specific range offered, likely due to SF’s characteristic marine cooling, which often keeps mid-July highs below 75°F [2]. Comparable markets, such as the July 9 2026 high where the 68–69°F band held 37.5% implied probability, illustrate how fragmented outcomes and low-confidence clustering shape pricing in weather prediction markets [1].

Traders should monitor the National Weather Service’s daily climatological reports issued for KSFO, particularly the summary released on 12 July, which confirms normal and record temperatures for the day [6]. Any deviation from the 1991–2020 climate normals—such as an unexpected heat dome or wind shift from the Pacific—could alter the high significantly. While no immediate news catalysts have been announced, the settlement window ends at 12:00 UTC on 12 July, meaning real-time Wunderground updates will be the final arbiter [10].

Regulatory access hinges on jurisdiction: German operators must comply with GlüStV licensing, while US participants face CFTC oversight on prediction contracts. The platform’s ‘no-KYC up to $1,500’ threshold allows traders in permitted regions to access this market without identity verification, provided they remain under the limit. This structure enhances accessibility for weather-focused speculation but does not override local gambling or financial regulations.

FAQ

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Is Kalshi Legit 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. Is Kalshi Legit 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), Is Kalshi Legit would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
