Highest temperature in Sao Paulo on June 30?

Platform comparison

Market context

The real-world event this market tracks is the peak air temperature recorded at Sao Paulo-Guarulhos International Airport on 30 June 2026, measured in degrees Celsius. Historical data shows June is the coldest month in Sao Paulo, with average highs around 22°C (72°F) and lows near 13°C (56°F), while the city’s absolute record high is 38.5°C, set in November 2023. Recent Polymarket outcomes for late June 2026 (e.g., 24 and 26 June) resolved to “No” for ranges above 15–19°C, aligning with seasonal norms where temperatures rarely exceed 25°C. This supports the current 0% crowd-implied probability for any range significantly above typical June highs, as extreme heat events in this month are statistically negligible.

Traders should monitor daily Wunderground reports for SBGR, the official resolution source, and watch for any anomalous weather alerts from Brazil’s National Meteorology Institute (INMET), which occasionally issues heat advisories during unseasonal warm spells. While no recent news cites extreme June heat in Sao Paulo, PredictWind’s June 2026 historical records confirm stable, cool conditions with no temperature spikes above 24°C. Regulatory accessibility hinges on jurisdiction: German GlüStV may restrict unlicensed prediction markets, while US CFTC reach applies to platforms offering contracts on commodity-like variables. The “no-KYC up to $1,500” threshold allows retail traders in compliant regions to access this market without identity verification, provided they fall under local de minimis exemptions for low-stakes speculative instruments.

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.

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 Legal UK 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).
