Market outcomes
| ASP Promitheas vs. Iraklis | 100% YES | 0% NO |
ASP Promitheas will face Iraklis in a Greek Basketball League match on 25 April at 11:15 AM ET. The current order book on Polymarket reflects a 100% implied probability for ASP Promitheas, indicating traders are pricing this as a near-certain outcome for the Promitheas side. This extreme probability typically emerges when one team holds a substantial competitive advantage or when market participants have converged on a dominant view of the matchup's likely result.
Greek Basketball League fixtures between these clubs historically show Promitheas as the stronger franchise in recent seasons. Promitheas competes at a higher level within Greek basketball and has maintained superior win rates against comparable opposition. The current probability formation suggests the market is treating this as a heavily favoured matchup for Promitheas, though such extreme probabilities leave minimal margin for upset scenarios or execution variance on match day.
Traders should monitor team news through the settlement window closing 2 May, particularly any late injury announcements or roster changes that could affect either side's competitive standing. The Greek Basketball League schedule occasionally experiences postponements due to administrative or logistical factors. Any confirmation of the fixture proceeding as scheduled, or conversely, any announcement of postponement or cancellation, would constitute material information. The settlement mechanism includes provisions for postponement (market remains open) and cancellation without rescheduling (50-50 resolution), creating distinct outcomes beyond the binary match result itself.
This market settles from the official outcome published at https://www.esake.gr/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "ASP Promitheas vs. Iraklis" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$3K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
As of today, traders on Polymarket price this outcome at 100%. The number updates continuously as the order book clears. PolyGram mirrors the same live odds with locale-aware formatting and USDC settlement.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
