Trade: Primeira Liga: 16th Place (Relegation Survivor)
Resolution criteria on PolyGram: This market will resolve to "Yes" if the listed team finishes 16th in the 2025-26 Primeira Liga. Otherwise, the associated market will resolve to "No". If at any point it becomes impossible for the listed team to finish 16th in the 2025-26 Primeira Liga (e.g. they mathematically cannot finish in 16th), the associated market will resolve to "No". If the 2025-2026 Primeira Liga season is cancelled, postponed after May 31, 2026, 11:59 PM ET, or there is otherwise no 16th place team declared within that timeframe, this market will resolve to “Other”.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon.

Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

Market context
The 2025–26 Primeira Liga season will determine which Portuguese club finishes in 16th place and thus secures survival in the top flight through the play-off system. The market currently shows 0% implied probability on Polymarket's order book, indicating traders assess the listed team as having effectively no realistic path to that exact finishing position. This extreme pricing reflects either strong conviction that the team will finish higher, or conversely, that relegation or mathematical elimination is the more probable outcome.
Primeira Liga's 16th-place finisher enters a two-legged promotion–relegation play-off against the second-placed team from the second division. Historical precedent shows that teams finishing 16th typically face genuine jeopardy; since the play-off system's introduction, several top-flight clubs have dropped to the second tier after finishing in this position. The current 0% probability suggests market participants view the listed team's underlying quality, squad composition, or recent form as substantially stronger than a 16th-place trajectory, or alternatively, that downward momentum makes even 16th unattainable.
Traders should monitor squad changes during the January transfer window, managerial stability, and fixture congestion as the season approaches its May 2026 conclusion. Injury crises, unexpected managerial departures, or a sustained run of poor results could shift the probability upward. The settlement window closes 1 June 2026, allowing for any outstanding matches or administrative clarifications to be resolved before final standings are confirmed by the Portuguese Football Federation.

How active is this market?
$3K in lifetime turnover and $26 of resting liquidity puts this market in the below the median by volume for soccer 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 around 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.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.

- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token

Risk and regulatory note
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.
