Market outcomes

| Draw | 0% YES | 100% NO |
| Samsunspor | 0% YES | 100% NO |
Rams Başakşehir FK will host Samsunspor in a Süper Lig fixture on 9 May 2026, with settlement determined by the halftime scoreline after 45 minutes plus stoppage time. The current orderbook on Polymarket is pricing a home halftime win at 100% implied probability, reflecting either extreme confidence in Başakşehir's first-half dominance or minimal liquidity in the market at present.
Halftime markets in Turkish football have historically shown volatility when one side carries significant form advantage or tactical reputation for early pressure. Başakşehir, as Istanbul's second-largest club by infrastructure, typically commands stronger squad depth and often establishes early control in home fixtures. However, a 100% probability across any three-way halftime outcome is uncommon in established markets and usually signals either a data feed issue, thin order book depth, or settlement mechanics that traders should verify before committing capital. Comparable Süper Lig halftime markets have typically settled with home results in the 45–55% range depending on opponent quality.
Key variables include team news announcements in the week prior to 9 May, any fixture postponements affecting preparation schedules, and whether either side faces competing domestic or European commitments that might influence squad rotation. Traders should monitor official Süper Lig communications and club statements for injury updates or tactical shifts. The settlement window closes at 17:00 UTC on match day, allowing only the halftime whistle to determine outcome—no late-match reversals apply.
This market settles from the official outcome published at https://tff.org/. 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 "Rams Başakşehir FK vs. Samsunspor - Halftime Result" 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.
$415 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.
Resolution is sourced from https://tff.org/. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 9 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
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.
