A boxing promotion is essentially the sponsor(s) putting on a given bout. Professional boxers sign contracts with these promotions, and fighters often primarily fight other pugilists within their own promotions. However, for the biggest fights, you will see boxing cross promotions, as one agency’s top dog with face off against another’s. These are usually the biggest fights in boxing, and they always generate the most online boxing betting odds. Some of the most notable promotions in pro boxing today are the following (managers/owners in parentheses): Golden Boy Promotions (Oscar de la Hoya) Top Rank (Bob Arum) Matchroom (Eddie Hearn) Main Events (Cathy Duva) Mayweather Promotions (Floyd Mayweather, Leonard Ellerbe) Hayemaker Ringstar (Richard Schaeffer) K2 (Tom Loeffler) Premier Boxing Champions (Al Haymon)
