Biggest Bookmakers

A bookmaker having a large number of customers certainly suggests that the company is reliable and offers high quality services. If it were otherwise, it would not have been able to attract so many customers.

Bookmakers with more than 10 million customers are the most popular platforms for betting on sports.

Their names are generally recognized around the world.

These companies can surely be recommended for betting, to both novice and professional bettors.

In 2025, the largest bookmakers not only had a large number of clients, but also own websites that allow bettors from all over the world to participate regardless of their physical location and place their bets on sports in a fully online regime.

To truly understand just how large a betting company really is, you need to add up all of its main offline and online indicators and only then can you obtain a truly objective result.

  • OKThe total number of clients of the bookie
