Considerations

• Player Participation: While top players like Jannik Sinner and Carlos Alcaraz are expected to participate, final player lists are subject to change due to injuries or scheduling decisions.

• Rankings Verification: For the market concerning players outside the top 10 reaching the finals, it's essential to verify the ATP rankings as of June 9, 2025, to determine eligibility.

• Surface Performance: Grass courts can favor certain playing styles. Historical performance on grass may influence outcomes, but upsets are possible, especially with emerging talents.

Traders should monitor official announcements and player conditions leading up to the tournaments for informed decision-making.
