Market context
On 25 July 2026, the highest temperature recorded at Taipei Songshan Airport Station will fall into one of several defined ranges in Celsius. The settlement will draw from Wunderground's historical weather database, which archives daily extremes for this official meteorological station. The current crowd-implied probability of 0% suggests traders are not yet pricing in any particular temperature band, reflecting either early-stage market formation or consensus uncertainty about which range will ultimately resolve.
Taipei's July temperatures historically cluster between 32–36°C, with occasional peaks above 37°C during heat waves. The 2015 heat event saw Taipei reach 38.3°C in mid-July; more recently, July 2023 recorded sustained highs in the 35–37°C band. These precedents matter because they establish the plausible range: extreme outliers (sub-30°C or above 40°C) remain meteorologically possible but statistically rare for this season and location. The absence of early trading activity may reflect that traders are awaiting clearer seasonal forecasts or waiting to see whether tropical systems develop in late June that could suppress temperatures.
From a regulatory standpoint, this market operates under frameworks that vary by jurisdiction. Under German GlüStV rules, prediction markets on weather events may face stricter classification depending on whether they're deemed gambling or financial instruments. US CFTC oversight typically exempts small-scale prediction markets, though binary weather contracts can fall under commodity derivatives rules if notional value exceeds thresholds. For traders in no-KYC jurisdictions where position limits cap at $1,500 USD equivalent, this market's relatively narrow settlement window (single day) and defined outcome space make it accessible without identity verification on many platforms, though settlement certainty depends entirely on Wunderground data availability on the resolution date.

FAQ
- 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.
- 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.
- 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).
