Riot Games Evaluates Prediction Market Sponsors for Esports

Riot Games, the developer behind League of Legends and Valorant, is currently discussing potential sponsorship agreements with prediction market operators Kalshi and Polymarket. These talks are taking place ahead of the upcoming League of Legends World Championship in October. However, the company has not committed to either platform and is proceeding with caution.

The discussions highlight a shift in how esports monetizes fan engagement, moving from traditional sports betting toward prediction markets. Riot is evaluating these options based on their impact on competitive integrity, the value they provide to teams, and the overall fan experience. This approach reflects a broader trend in the industry to bring regulated or semi-regulated financial instruments closer to live competitive gaming.

Data Control Protects Competitive Integrity

A key condition in these potential deals is the requirement for any approved sponsor to use official betting data supplied through Riot’s partner, GRID Esports. This ensures that the data used for prediction markets is accurate and sourced directly from the game servers. By mandating this data flow, Riot aims to prevent the use of unreliable or manipulated information that could undermine the fairness of the competitions.

GRID Esports already has an existing relationship with Polymarket, having granted them access to official esports data in June. This infrastructure allows for faster data streams and a more accurate reflection of in-game events. For Riot, controlling the data source is a critical trade-off, as it limits the platforms' ability to rely on third-party or unverified feeds, but it safeguards the ecosystem from integrity issues.

Regulated Markets Challenge Unlicensed Bookmakers

According to data cited by Riot, betting tied to its major titles reached 10.7 billion dollars in 2024. Most of this activity occurred through unregulated markets and unlicensed bookmakers. By partnering with established prediction market operators, Riot seeks to bring a portion of this activity into a more controlled environment. This move aligns with the company's decision in 2025 to permit sponsorships from traditional sports betting operators, subject to strict restrictions.

Prediction markets differ from traditional betting in that they allow users to take positions on specific outcomes without necessarily placing a wager in the traditional sense. This distinction may appeal to a younger esports audience that is less familiar with conventional sports betting. However, the financial mechanics remain complex, and the platforms must navigate varying regulatory landscapes across different jurisdictions.

Prediction Markets Expand Into Sports

The interest from Riot Games is part of a larger trend where prediction market platforms are expanding their presence in professional sports and entertainment. Kalshi recently secured an exclusive partnership with the U.S. Tennis Association for the US Open, gaining prediction market partner status. This deal restricted competing platforms from advertising at the venue and during television coverage, signaling a push for exclusive, high-profile associations.

Polymarket has pursued a similar strategy, signing agreements with properties including Major League Baseball and the Bundesliga. These moves indicate that both companies are aggressively seeking to establish themselves as primary partners in major sporting events. For Riot, engaging with these platforms offers a way to tap into this growing market while maintaining strict control over how its games are represented in these financial instruments. As reported by GN technics/gaming, the outcome of these talks will set a precedent for how other esports organizations handle prediction market sponsorships.
