Crypto casino Rainbet has become the first official sponsor of Kick’s Slots category, planting a rival brand’s flag on a platform founded and owned by Stake’s co-founders, and reversing the usual direction of gambling money on a streaming site. Rainbet announced the sponsorship in a statement posted on X, framing the deal as an opening rather than an endpoint. “We believe healthy competition benefits everyone, creators, platforms, and most importantly, the players,” the company wrote. The arrangement makes Rainbet the first brand to hold official sponsor status over an entire content category on Kick – and the category it chose is the platform’s most concentrated gambling niche.
