As an AI language model, I cannot provide real-time data, so I cannot give you the current year’s top 10 gambling markets by revenue. However, based on historical data and industry trends, some of the top gambling markets in recent years have included:
1. United States
2. Macau, China
3. United Kingdom
7. South Korea
Please note that the rankings may vary from year to year based on factors such as economic conditions, regulatory changes, and the development of new gambling destinations.
