The latest addition to the growing family of online casino Rainbet’s ambassadors is yet another big UFC name. It is not every day that a brand can secure a superstar of a popular sport, but Rainbet seems to have a knack for it. American mixed martial artist Sean Strickland, 35, will be joining the roster that already consists of a few of his fellow colleagues. He has signed on as the latest Ultimate Fighting Championship ambassador for the gambling platform as Rainbet continues positioning itself as a UFC focused sportsbook. 

An Explosive Video Announcement, Literally

In a brand new promotional video announcing the partnership between the fighter and the sportsbook, fans can see Strickland front and center in a fun and engaging piece. Quality and high tier cinematography are obvious as the brand spared no expense to let sports betting and UFC fans know the news. So, what happens in the video and how does the brand introduce their latest addition?

The 35 second promotion starts with a granny playing on a slot, a typical sight at any brick and mortar casino these days. It is a trope that only the elderly still play in physical casinos, something which Strickland aims to put an end to right here and now. With some wacky and funny dialog, complemented by actors doing their thing, he claims that gambling the old fashioned way is no longer viable. Instead, gambling the Rainbet way is far better, and he shows you why.

Not to spoil the fun of the video, Sean Strickland tells the viewers to join him and use the platform. Online casinos and sportsbooks are here to stay; they are the present and no longer the future, and with the growing list of big names joining the roster, Rainbet UFC Betting will never be the same now that the two time champion is here. The existing community will be happy with another star in their midst, while Sean’s huge following will surely be making their way to the platform and bringing their fandom along. Rainbet’s UFC betting markets are now bigger than ever, just in time for UFC Fight Night: Hernandez vs Rodrigues on August 22. 

Rainbet’s Growing Ambassadors Roster 

Before Strickland, Rainbet had already built its brand visibility largely through high profile influencers, streamers, esports and combat sports partnerships. The strategy became increasingly prominent in 2025. One of its most significant moves came in May 2025, when Rainbet became the main jersey partner of Ninjas in Pyjamas (NIP), putting its logo on the Counter-Strike 2 team’s official jerseys and connecting the casino brand directly with the global esports audience. NIP described the agreement as a major commercial partnership designed to support content, fan experiences and community initiatives.

The brand’s ambassador strategy has also centered heavily on internet personalities. Adin Ross became one of Rainbet’s most recognizable promotional figures after joining the company in 2025, with his gambling streams helping generate substantial exposure. Rainbet has also worked with a wider group of creators and streamer personalities, including Jay Ferrer, Lenny Miller, Louie Gambles and Nikola Mijomanovic, while its partnerships have extended to streamer collective SSB. Rainbet’s own promotional material emphasizes the idea of using personalities who already have established relationships with gaming and streaming audiences.

During 2026, Rainbet expanded beyond gaming and streaming into mainstream sports and entertainment. Ryan Garcia has appeared in Rainbet’s partnership activity, while UFC fighter Justin Gaethje was added as a brand ambassador in July 2026. The Gaethje collaboration was first publicly noticed during UFC Fight Night on July 18, when he appeared wearing Rainbet branding, before the company subsequently promoted the partnership. Around the same period, rapper Lil Pump was reported as a new Rainbet ambassador, although claims about the financial value of that agreement remain unverified.

Rainbet has simultaneously increased its sponsorship presence. In 2026, the company became the first official sponsor of the Slots section on Kick, strengthening its relationship with the livestreaming ecosystem. It has also moved into combat sports, becoming the title sponsor of a Bare Knuckle Fighting Championship event in Birmingham. Overall, Rainbet’s sponsorship history shows a deliberate shift from a primarily online gambling brand toward a broader entertainment identity built around influencers, esports, streaming, boxing and MMA, with celebrity ambassadors providing much of its visibility.
