Maria Sharapova promotes Polymarket amid rising tennis prediction market integration

Former world number one Maria Sharapova is appearing in a new promotional campaign for Polymarket, a prediction market platform. The campaign features Sharapova trading live positions while watching tennis matches, highlighting the platform's ability to react to real-time match developments.

This marketing push coincides with a growing integration of prediction markets within professional tennis. Polymarket has become the official prediction market provider for the ATP Tour through an agreement with Tennis Data Innovations, granting access to data and streaming rights for approximately 20,000 matches annually. Similarly, the platform Kalshi has established a multi-year partnership with the United States Tennis Association (USTA) as the exclusive prediction market partner for the US Open.

The involvement of high-profile figures like Sharapova has reignited discussions regarding the ethics and consistency of betting regulations in the sport. While governing bodies and tournaments enter commercial partnerships with prediction platforms, strict anti-corruption rules continue to prohibit active players and their teams from engaging in betting-related sponsorships.
