Rainbet Casino names UFC champion Justin Gaethje as ambassador

Rainbet has added another well-known name from the UFC to its list of ambassadors. The company confirmed a partnership with former UFC lightweight champion Justin Gaethje after the fighter shared the news on his social media.

The announcement followed an appearance at UFC Fight Night on July 18. Fans watching the event noticed Gaethje sitting in the arena wearing a T-shirt featuring Rainbet branding, with the logo visible during the official UFC on Paramount+ broadcast.

That statement marked the first official confirmation from the fighter himself.

A New Deal Just Months After Duelbits

The move is notable because Gaethje only recently represented another crypto casino.

Earlier this year, in April, Duelbits introduced the UFC athlete as one of its ambassadors. His switch to Rainbet means the fighter has changed commercial partners within just a few months.

Neither side has disclosed how long the new agreement will run or what promotional activities are planned.

Casino Companies Continue to Target UFC Athletes

For UFC fans, deals like this are hardly unexpected. Casino brands have been signing well-known fighters for years, and new partnerships are usually announced through the athletes' own social media accounts or public appearances.

McGregor's story went even further. He didn't stop at sponsorship deals and later became a co-owner of REALBET.IO.

Rainbet's latest agreement with Gaethje follows the same approach, bringing another internationally recognised UFC athlete into the company's marketing lineup. For the casino, it is another opportunity to strengthen its profile among combat sports fans, while Gaethje adds another commercial partnership outside the Octagon.
