Resolution criteria on PolyGram: This market will resolve to "Yes" if Neymar da Silva Santos Júnior takes the field as a player in at least one official match for Brazil during the 2026 FIFA World Cup at the group stage or later. Otherwise, this market will resolve to "No". Any on-field appearance as a player will qualify, in regulation, stoppage time, extra time, for a shootout, etc. The primary resolution source for this market will be information from FIFA (https://www.fifa.com/), however a consensus of credible reporting will also be used.
Real-money prediction markets aggregate live odds from thousands of traders, surfacing a sharper probability than any single forecast. Current odds favour the YES side at 90%, making this a high-confidence market with 48 days to resolution — long enough that information asymmetry can still move the line meaningfully, backed by $82K of resting liquidity.

Market outcomes
| Will Neymar play in the World Cup? | 90% YES | 11% NO |
The 2026 FIFA World Cup will take place across North America in June and July, with Brazil expected to compete as one of the tournament favourites. Neymar, currently 34 years old, will be 35 during the competition. The market question hinges on whether he will appear in at least one official match for Brazil during the tournament. The 90% implied probability on Polymarket's order book reflects strong confidence in his participation, though this carries material uncertainty given the timeframe and his injury history.
Comparable cases suggest caution around ageing star players in World Cup cycles. Cristiano Ronaldo played in the 2022 Qatar World Cup at age 37, though his minutes were limited. Pelé never played in a World Cup past age 30. Neymar's recent career has been marked by recurring injuries—he missed significant portions of the 2022 World Cup cycle and has experienced multiple muscle and ligament injuries since joining Al-Hilal in Saudi Arabia in 2023. His availability for Brazil's qualifying campaign and club form through 2025–26 will be critical indicators of fitness levels heading into the tournament.
Key catalysts for traders to monitor include Neymar's performance and injury record during the 2025–26 club season, Brazil's official squad announcement (typically weeks before the tournament), and any statements from the Brazilian Football Confederation regarding his selection. His continued participation in competitive matches at club level will signal whether he remains in contention. Any significant injury during the qualifying period or immediately before the tournament could shift market expectations materially.

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. For "Will Neymar play in the World Cup?", the considerations above apply directly — Trade size should reflect the binary nature of the payoff: even a 70% probability event resolves NO 30% of the time, so any single position can lose 100% of staked capital.
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.
