Tencent Holdings Ltd.'s Riot Games, maker of League of Legends and Valorant, has discussed esports sponsorship deals with Polymarket and Kalshi. The talks signal interest from a major gaming publisher in bringing prediction market branding into professional esports, though no deals have been announced. Riot operates some of the most-watched esports leagues globally, giving any eventual partnership significant reach.

A Riot deal would put prediction markets in front of tens of millions of young, digitally native viewers. It would also test whether CFTC-regulated platforms can advertise in gaming contexts without triggering gambling-ad restrictions that vary by state.
