Riot Games, the Tencent-owned publisher behind League of Legends and Valorant, has held discussions with prediction market operators Kalshi and Polymarket about potential esports sponsorship deals, Bloomberg reported on September 10, 2026, citing people with knowledge of the conversations. No agreement has been finalized, and the talks remain ongoing.
Riot Evaluates Prediction Markets for Esports Ecosystem
Riot Games spokesperson Joe Hixson confirmed the company’s interest in the space. “Prediction markets are an emerging space that we’re evaluating with a focus on safeguarding competitive integrity, potential value for teams, impact on the fan experience, and alignment with our broader ecosystem goals,” Hixson told Bloomberg.
The discussions come ahead of the 2026 League of Legends World Championship, which is scheduled to begin in October. The timing suggests Riot may be exploring whether prediction market sponsorships could be activated around one of esports’ highest-profile annual events. Kalshi declined to comment on the talks, according to Bloomberg’s report. Polymarket has not publicly responded.
GRID Esports Data Requirement Signals Integrity Focus
A source familiar with the discussions told Bloomberg that any approved prediction market sponsor would be required to use official betting data supplied by GRID Esports, Riot’s existing data partner. The condition points to a structured approach: rather than simply selling sponsorship inventory, Riot appears to be setting guardrails that would channel prediction activity through monitored, official data channels.
GRID already provides real-time esports data to betting operators and has separately announced a partnership with Polymarket to supply livestreams and real-time esports data. That existing relationship between GRID and Polymarket could simplify the data infrastructure side of any eventual Riot sponsorship deal.
What Kalshi and Polymarket Bring to the Table
Kalshi and Polymarket are two of the most prominent prediction market platforms operating in North America. Both allow users to trade contracts on the outcomes of real-world events, including sports and entertainment. Kalshi is a regulated exchange approved by the Commodity Futures Trading Commission (CFTC) in the United States, while Polymarket has operated primarily in the crypto-adjacent prediction space.
The two platforms have been expanding aggressively into sports. Kalshi recently signed a deal with ADI Predicstreet, FIFA’s official World Cup prediction market partner, gaining co-branding rights at the tournament. The push into esports represents a natural extension for both companies, given the demographic overlap between prediction market users and competitive gaming audiences.
Industry Reaction: Control Over Revenue
Early analysis from industry observers framed the talks as a move by Riot to bring structure to a space that already exists in an unregulated form. Analysts at AInvest noted that Riot’s approach appears focused on channeling what they described as an estimated USD 10.7 billion in unregulated gambling activity on its games into monitored systems, prioritizing observability over traditional advertising revenue.
“This is about control, not ads,” AInvest’s analysis stated, arguing that Riot’s insistence on GRID data usage and competitive integrity safeguards suggests the publisher views prediction market partnerships as a way to gain visibility into betting patterns that currently operate outside its oversight.
The esports industry has long grappled with the question of how to handle betting-adjacent partnerships. Traditional sportsbooks have sponsored esports leagues and teams for years, but prediction markets occupy a legally distinct category. In the United States, prediction markets are generally structured as event contracts rather than traditional sportsbook wagers, and their regulatory treatment varies by jurisdiction.

Singapore and Southeast Asia Implications
While the Bloomberg report focused on Riot’s North American discussions, the implications extend to Southeast Asia. Singapore serves as a major hub for esports operations in the region, and both League of Legends and Valorant maintain significant competitive ecosystems across the Asia-Pacific. Any shift in Riot’s global sponsorship policy on prediction markets could affect regional tournament sponsorship packages, broadcast deals, and fan engagement strategies.
Singapore’s regulatory environment around gambling and prediction markets is notably strict. The Gambling Regulatory Authority of Singapore oversees all gambling-related activity, and any prediction market sponsorship visible in Singapore-based tournaments or broadcasts would need to navigate that framework. The Esports World Cup 2026 and other major events have already demonstrated that sponsorship compliance varies significantly across host jurisdictions.
Broader Precedent for Esports Betting Partnerships
Riot’s exploration of prediction market sponsorships follows a broader trend across esports. Traditional betting operators have held sponsorship positions in leagues such as the LEC in Europe and various Counter-Strike circuits. However, prediction markets represent a newer category that blurs the line between financial instruments and sports wagering.
The move also comes as Riot prepares for the VCT Champions 2026, scheduled from September 24 to October 18 in Shanghai. With both the League of Legends Worlds and VCT Champions approaching, any sponsorship deal struck in the coming weeks would gain immediate visibility across two of esports’ largest annual events.
What Comes Next
The talks between Riot, Kalshi, and Polymarket remain in the discussion phase with no confirmed timeline for a decision. Hixson’s statement framing prediction markets as an area under evaluation, rather than a committed partnership direction, leaves room for the talks to stall or evolve.
Key factors to watch include whether Riot formalizes a sponsorship ahead of the League of Legends World Championship in October, how other major esports publishers respond if Riot moves forward, and whether regulators in key markets raise objections to prediction market branding in competitive gaming broadcasts. For now, the story signals that one of esports’ most influential publishers is seriously weighing a category of sponsor that would have been unthinkable just a few years ago.
