Gambling in Esports Heats Up: Oddin Expands, BIG Joins Razed, LoL Gains at Kalshi

Gambling in esports is moving fast, with three notable developments reshaping how fans and bettors engage with competitive gaming. Oddin.gg is expanding its footprint, Berlin International Gaming has partnered with esports betting platform Razed, and League of Legends is seeing increased activity on prediction market platform Kalshi, according to reporting by Esports Insider.

Oddin.gg Pushes Further Into Esports Betting

Oddin.gg, a specialist esports odds feed provider, continues to grow its presence in the betting market. The company has been steadily working to position itself as a core infrastructure layer for sportsbooks looking to offer esports markets. Its expansion signals sustained commercial interest from traditional betting operators who want reliable, esports-specific data rather than relying on generic sports betting frameworks.

Oddin's model focuses on supplying odds feeds to licensed bookmakers rather than operating a consumer-facing sportsbook itself. That B2B approach has helped it build partnerships across regulated markets, where operators need data they can trust for fast-moving esports titles like CS2, Dota 2, and League of Legends.

BIG Strikes Partnership With Razed

Berlin International Gaming, one of Europe's more recognizable esports organizations, has entered into a partnership with Razed, a platform built specifically around esports betting. The deal adds BIG to a growing list of esports teams aligning with betting brands as sponsorship revenue in the sector continues to evolve.

Partnerships between esports clubs and betting platforms have become more common over the past several years. For organizations like BIG, these deals offer a revenue stream that can help fund rosters and operations. For platforms like Razed, the association with a known competitive brand provides visibility among an engaged, game-literate audience.

The specifics of the deal's financial terms were not disclosed in the original reporting.

League of Legends Betting Grows on Kalshi

Kalshi, a regulated prediction market platform operating in the United States, is seeing League of Legends gain traction among its users. Kalshi operates under a different regulatory structure than traditional sportsbooks, offering event contracts rather than conventional fixed-odds bets. That distinction has allowed it to offer markets on esports events in jurisdictions where standard esports betting remains legally complicated.

League of Legends is the world's most-played PC game by active player count and consistently draws large viewership for its regional leagues and international tournaments. Growing betting interest on Kalshi reflects both the title's broad audience and increasing mainstream comfort with esports wagering as a category.

The platform's growth in esports markets is part of a wider trend of prediction market sites testing appetite for competitive gaming content alongside traditional sports like baseball and basketball.

What This Means for the Esports Betting Market

Taken together, these three developments point to a sector that is maturing rather than simply expanding. Oddin's infrastructure growth, BIG's brand partnership, and Kalshi's market activity each represent a different layer of the gambling in esports ecosystem: data supply, team sponsorship, and consumer-facing wagering.

Regulatory complexity remains a real constraint. Esports betting is still not uniformly legal across U.S. states, and operators in Europe face varying licensing requirements by country. Despite that, commercial activity is clearly increasing, and more organizations, both on the team side and the platform side, are treating esports betting as a serious, long-term business line rather than a niche experiment.
