MLB

History and Legal Structure

The modern MLB structure grew out of the 1903 National Agreement between the National League, founded in New York City on February 2, 1876, and the American League, which achieved major-league status in 1901. The Office of the Commissioner was created in 1920 in response to the Black Sox scandal and became the central executive authority for the sport. In 2000, MLB was consolidated as a single legal entity, with the AL and NL effectively reduced to divisions of the league. The commissioner’s office sits at 1271 Avenue of the Americas in New York and negotiates national media, sponsorship, licensing, data, and gaming agreements on behalf of all 30 clubs.

Business Model and iGaming Position

MLB is not a betting operator or platform supplier. It is the ultimate upstream rights-holder in the baseball wagering chain, selling official brand rights, exclusive game data, and live content to regulated sportsbooks and media companies. This model took its modern form after the fall of PASPA: in August 2018 MLB and MGM Resorts announced a multi-year deal naming MGM its Official Gaming Partner and Official Daily Fantasy Partner, one of the first major league-operator partnerships of the post-PASPA era. In 2021 the league shifted to a multi-partner approach, adding DraftKings, FanDuel, and bet365 as Official Sports Betting Partners while BetMGM continued through the MGM relationship. Official game data reaches licensees through MLB’s long-standing relationship with Sportradar. The commercial gaming unit is led by Executive Vice President Kenny Gersh, whose remit includes betting partnerships and the MLB Play product.

Product and Platform Stack

MLB’s consumer and media portfolio includes MLB.com, MLB.tv, the MLB app (formerly At Bat), MLB Network, the Ballpark app, and Statcast, the Hawk-Eye optical tracking system that feeds advanced analytics to clubs, broadcasters, and content licensees. The league also operates MLB Play, a free-to-play prediction platform launched in 2022 that functions as MLB’s own betting-adjacent fan product. These assets support a broad licensing business, and official data and video feeds are sold into the regulated betting ecosystem to power pricing, in-play products, and content.

Integrity and Regulatory Role

Because MLB’s players, umpires, and staff are the subject of wagering, the league runs a highly visible integrity program. MLB personnel are barred from betting on baseball; betting on other sports is allowed for big-league employees where state law permits, while Minor League players and umpires face a total ban on all sports betting. The regime was underscored in 2024, when MLB issued a lifetime ban to San Diego Padres infielder Tucupita Marcano for betting on baseball and suspended four Minor League players. It also investigated gambling activity by Shohei Ohtani’s former interpreter, Ippei Mizuhara. At the policy level, MLB has joined the NFL and other leagues in pressing for integrity safeguards in federal debates over event-based contracts, including CFTC rulemaking on sports and political prediction markets—the context in which MLB was first surfaced in this database.

Market Position and Competitive Landscape

Within the sports-betting rights market, MLB competes with the NFL, NBA, and NHL for operator sponsorship budgets and official data deals, but its revenue from gambling is concentrated in rights, data, and integrity services rather than handle. The league’s large domestic fan base, 30-club footprint, and daily summer schedule make its inventory particularly valuable for in-play and daily-fantasy products. Its partnerships with DraftKings, FanDuel, bet365, and BetMGM give it representation across nearly all major regulated US sportsbooks, and its international growth ambitions point toward additional operator relationships outside North America.

Recent Developments and Outlook

MLB’s betting strategy is expected to deepen alongside legalisation: the league has signalled interest in data-rich products built on Statcast, closer integration between broadcasts and betting content, and expansion of official-partner deals internationally. The principal constraints are regulatory fragmentation across US states, the unsettled federal status of event contracts, and the permanent integrity risk that legalised wagering creates for a sport whose past gambling scandals—from the Black Sox to Pete Rose—remain central to its institutional memory.
