Resolution source: This market settles from the official publication at https://www.wunderground.com/history/daily/kr/incheon/RKSI. A proposer submits the result to the UMA Optimistic Oracle on Polygon, the two-hour challenge window opens, and the smart contract pays out in USDC.

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. PolyGram has a different geo footprint.
Do I need to KYC for PolyGram?
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.
What happens during a tax audit?
You're responsible for documenting your trades. PolyGram 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.
