1xBet Becomes First Betting Partner of MIBR in Riot Ecosystem

Operator 1xBet has become the first betting partner in the Riot Games ecosystem by signing a deal with the Brazilian esports organization MIBR for their VALORANT roster.

History and Significance of the Partnership

As of November 26, 2025, MIBR officially became the first organization across the entire Riot ecosystem to receive approval for a betting sponsorship. This achievement is the result of an extensive compliance process that began earlier this year after Riot announced the opening of the League of Legends and VALORANT markets in the Americas and EMEA to companies in the betting segment.

The partnership with 1xBet already had a successful track record with MIBR. It began in January 2022 with Counter-Strike and was expanded in early 2025 to include the MCs of the MIBR Rap Clube. Now, the agreement also incorporates the mixed VALORANT team, becoming a new pillar of the partnership.

Role of the Ambassador and Activities

The contract includes streamer Sacy as the ambassador and face of this new phase of the partnership. All activities will comply with the developer’s policies, uphold competitive integrity, and follow responsible communication principles.

Comments from MIBR Representatives

Raphael Castanheira, MIBR’s Director of Marketing and Partnerships, stated: “Becoming the first organization across the entire Riot ecosystem to gain approval for a betting sponsorship is a direct result of how MIBR operates today: an organized company with strong governance, clear processes, and policies that prioritize competitive integrity. This preparation shortened the approval process.”

Partnership Expansion and Future Plans

With the expansion of the collaboration with 1xBet and the inclusion of the mixed VALORANT lineup, MIBR ends the year entering a new phase of activities with Sacy, as well as with the CS, VALORANT, and MIBR Rap Clube rosters.

All initiatives will strictly follow Riot’s policies and best practices for fair play, reinforcing MIBR’s commitment to generating value for the community and its partners. More details will be shared on the club’s official channels.

Key Points of the Partnership

  • The first-ever approval of a betting sponsorship in the Riot ecosystem
  • Inclusion of the mixed VALORANT team
  • Previously successful collaboration in Counter-Strike and MIBR Rap Clube
  • Project ambassador — Sacy
