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".

Market outcomes
| Will Neymar play in the World Cup? | 81% YES | 20% NO |
The 2026 FIFA World Cup will take place across the United States, Canada, and Mexico from June to July. Neymar, currently 34 years old, will be 35 at tournament time. The market asks whether he will appear in at least one official match for Brazil during the competition. The 81% implied probability on Polymarket's order book reflects confidence in his participation, though this carries material uncertainty given his age, injury history, and the competitive depth of Brazil's squad.
Historical precedent suggests established players of Neymar's stature typically feature in World Cup tournaments when fit. Pelé played at age 34 in 1970; Ronaldinho appeared at 34 in 2006. However, Neymar's injury record—including serious ACL damage in 2014 and recurring muscular issues—distinguishes his case. Brazil's attacking options have deepened considerably, with younger talents like Vinícius Júnior and Rodrygo now established. The current probability likely reflects base-rate expectations for a player of his calibre rather than specific confidence in his fitness trajectory.
Key catalysts include Brazil's qualifying campaign performance and Neymar's club status heading into 2026. His current position at Al-Hilal in Saudi Arabia means limited exposure to European competition, potentially affecting match fitness assessments. Any significant injury during the 2025-26 season, or managerial changes at the CBF, could shift the probability materially. Confirmation of Brazil's final squad in June 2026 will be the decisive signal, though selection alone does not guarantee playing time.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.

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.
