Zhejiang Lions vs. Shanghai Sharks

Platform comparison

Market context

The Chinese Basketball Association (CBA) will host a regular-season matchup between Zhejiang Lions and Shanghai Sharks on 2 June at 7:35 AM ET. The market resolves to the winner's name if the game concludes; if postponed, settlement extends until completion; if cancelled without rescheduling, the market splits 50–50. The settlement window closes 9 June at 11:35 UTC, allowing a week-long buffer for fixture confirmation and result publication.

A 100% implied probability for either outcome is unusual in two-team binary markets and typically reflects either extreme confidence in one side or liquidity constraints limiting price discovery. Historical CBA fixtures show cancellation or postponement is rare but not unprecedented—weather, administrative scheduling, or health protocols have occasionally disrupted the calendar. Comparable sports prediction markets on established platforms have resolved 50–50 only when fixtures were formally cancelled; postponements trigger market extension rather than settlement. The current probability should be interpreted cautiously given the settlement window's length relative to the fixture date.

Traders should monitor CBA official announcements for fixture confirmation, team roster updates, or scheduling changes. Recent reporting from CBA media channels and the league's official website typically confirms or alters match schedules 7–10 days prior. Injury disclosures or administrative notices from either franchise could shift market sentiment before the event. Under German GlüStV regulations, this market would require KYC verification for positions exceeding €1,500 notional value; US CFTC reach extends to certain prediction market operators, though treatment of sports contracts remains jurisdictionally variable. No-KYC access up to $1,500 means traders can establish positions without identity verification on compliant platforms, though larger exposures trigger standard regulatory documentation 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. 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.

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).
