The deal will see WMG become the long-term exclusive marketing partner of USA Gymnastics, USA Swimming and USA Track & Field.
Aside from sponsorship, event and marketing opportunities, WMG will also develop digital platforms to broaden distribution and original programming.
The three bodies will work together to secure deals.
WMG will build and manage individual online community portals for each sport within the company's new online sports network, Sportnet.
Casey Wasserman, chairman and CEO, WMG, said: “It is a privilege to be in business with three of the leading national governing bodies in the United States. Through an evolving and fragmented marketplace, this group has joined together with the vision and leadership necessary to take their organisations to this next level.”
