In 2018, Mastercard entered a groundbreaking partnership with Riot Games’ League of Legends esports and has since grown its marketing platform to reach more fans year over year. Initially focusing on on-site activation during events, Mastercard’s strategy evolved to encompass not only engaging with fans onsite but also online, leveraging the digital connectivity of the League of Legends audience year-round to build always-on fan engagement. In 2020, as the world moved into lockdown and physical activations were no longer possible, Mastercard shifted its focus to digital only and executed ambitious activations that put the fans at the center and brought them closer to their passion during these unprecedented times. The main objectives were to (1) drive awareness of the partnership via the @MastercardNexus Twitter handle, (2) build differentiation by providing value to the League community through, and (3) drive scale to truly tap into the global audience.


The League of Legends World Championship is the marquee tournament in League of Legends esports and is the most watched esports tournament in the world. 2020 marked its 10-Year Anniversary and represented an evolution not only of the event itself, but of the sport as a whole and everything players and fans have accomplished. To celebrate this important milestone, Mastercard put the spotlight on the fans who are the reason why League of Legends continues to be the most played and watched esport in the world. To thank them for everything they’ve done to elevate the esport and to recognize them for their contribution over the past decade, Mastercard launched the ‘Thank the Fans’ campaign on the day of the finals. Over the course of 10 hours, Mastercard celebrated the past 10 years of the esport by releasing Priceless digital experiences, exclusive items and in-game digital goods on


The core of Mastercard’s strategy is centered around the idea that every League of Legends fan has invested in the success of their passion’s meteoric rise.

As such, to celebrate the significance of the 2020 World Championship, Mastercard pushed out an ambitious activation plan that celebrated the power of the community with rewards that suited a variety of needs. This approach included Priceless experiences for fans to interact with key personalities, a bespoke Worlds capsule collection with gaming apparel company CLOAK, an exclusive content series highlighting the best plays in the esport, and in-game rewards for watching the broadcast. All efforts were amplified on the @MastercardNexus Twitter handle, which also served as the hub for constant fan interaction and engagement.
