MEXICO CITY, Sept ⁠14 (Reuters) - Mexico's antitrust regulator, CNA, said on Monday it had ⁠opened a formal investigation into possible anti-competitive practices in the country's ‌professional soccer market, after finding enough evidence to examine whether companies or institutions may have abused their market power.

The probe puts a spotlight on the business structure of Liga MX, Mexico's ​top soccer division, where club ownership and broadcasting ⁠rights have long been concentrated ⁠among a small group of powerful media and business interests.

• For decades, two ⁠broadcasters, ‌Televisa and Grupo Salinas' TV Azteca, held outsize influence through cross-ownership of teams and control of television rights. Their holdings have ⁠since been cut back to one club each. Neither ​company immediately responded to ‌requests for comment.

• The investigation covers the market for the affiliation, ⁠organization and access ​to professional soccer competitions in Mexico, as well as related services. Liga MX did not immediately respond to a request for comment.

• The move follows earlier action ⁠by Mexican competition authorities. In 2021, Cofece, ​the CNA's predecessor, fined 17 clubs and the national soccer federation 177.6 million pesos (then $8.87 million) for monopolistic practices.

• If the CNA finds violations, those responsible could face ⁠fines of up to 10% of annual revenue, along with orders to halt or correct the conduct.

• Soccer is a major industry in Mexico. The CNA said the sector generated more than 52 billion pesos ($2.8 billion) in ​2024 and supported about 150,000 jobs a year. It ⁠added that Mexico has the world's second-largest base of soccer fans, with roughly ​250,000 people attending matches each weekend.

• The ‌final of the 2026 World Cup, in ​which Mexico was a co-host, drew an estimated 30.5 million viewers in the country alone.
