This partnership ensures MGM will become the first official sports betting sponsor for the league and an investor.

The main provisions of the agreement state MGM will make an investment in The Alliance and a three-year sponsorship agreement which makes MGM an exclusive gaming partner.

The Alliance was founded by Charlie Ebersol and Bill Polian and claims to have new technology which is “revolutionary” and will create a “state of the art experience for fans.”

This partnership will allow the alliance to benefit from MGM’s knowledge and experience with mobile gaming.

When the Alliance launches its league in February next year, fans will be able to stream live matches for free through the league's mobile app and access integrated gaming services within the app and in states where sports wagering is legal, they can place wagers on the app.

MGM Resorts Chairman and CEO Jim Murren said: “We are excited to team with The Alliance on this unprecedented partnership, which allows us to fully engage with fans and revolutionise the fan experience.”

Charlie Ebersol, CEO and Co-Founder of The Alliance of American Football said: “Our focus has always been to bring together best-in-class partners to build a spring football league that will change the landscape of professional sports.

“We realised our overall mission and vision were in complete alignment with MGM. As one of the world’s largest and most successful gaming companies, and an industry leader in innovation, together we can revolutionise the sports wagering experience for fans in a way that’s never been done before.”
