Market context
On 17 August 2026, the highest temperature recorded at Ninoy Aquino International Airport in Manila will fall into one of several defined ranges. The resolution will draw exclusively from the Daily Observations table on Weather Underground, not the summary Day High & Low section, ensuring granular accuracy where discrepancies exist. Manila's August climate typically sees daily highs between 28–34 °C, with monsoon influence and occasional tropical systems affecting intra-day peaks.
Historical August temperatures at the airport station show clustering around 31–33 °C on most days, though extreme heat events pushing above 34 °C occur roughly once per decade during particularly dry or heat-dome conditions. The current crowd-implied probability of 0% for the highest range suggests traders expect a typical mid-range outcome rather than anomalous heat. Comparable August 2023 and 2024 data from the same station would anchor baseline expectations, though inter-annual variability remains substantial given the Philippines' exposure to both monsoon patterns and El Niño–Southern Oscillation cycles.
Traders should monitor the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) forecasts issued in early August 2026, which typically flag heat advisories or tropical cyclone activity weeks in advance. The settlement window closes at 12:00 UTC on 17 August, meaning final observations must be recorded by that deadline; any station outages or data delays could affect resolution timing. From a regulatory standpoint, this market operates under German GlüStV rules where applicable; US CFTC reach extends to US persons regardless of domicile, and the no-KYC threshold of $1,500 USD applies to aggregate positions across prediction markets on this platform, affecting accessibility for smaller traders in jurisdictions with stricter identification requirements.

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 Germany Legal 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.
- Can I trade anonymously?
- Pseudonymously, yes — up to the KYC threshold. Polymarket Germany Legal 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).
