Oddin.gg’s 2025 Esports Betting Review: Growth is up, but the story for operators is more complex
Oddin.gg has released The Oddin.gg Esports Betting Review 2025, its second annual analysis of global esports betting performance, drawing on billions of bets processed across its international partner network. The report finds that while major titles continued to post double-digit growth, the drivers behind that growth increasingly differ by title.
This year’s report covers five leading titles: Counter-Strike 2 (CS2), Dota 2, League of Legends (LoL), VALORANT and, for the first time, Mobile Legends: Bang Bang (MLBB). All five recorded between 18% and 62% year-over-year betting volume growth. However, according to analysis by Oddin.gg’s title experts, operators who treat esports as a single vertical risk misreading where growth is actually coming from.
As both the vertical and individual titles mature, the report highlights distinct behavioural patterns across the ecosystem, creating different strategic considerations for sportsbooks. Key trends and recommendations include prioritising player-focused markets for CS2 tournaments, strengthening in-play coverage for League of Legends – where the average stake at Worlds rose +166% YoY – and expanding combination markets in Dota 2, where these markets quadrupled in volume year-over-year.
Among the biggest developments this year was the performance of Mobile Legends: Bang Bang, which recorded +62% YoY bet count growth and +41% YoY betting volume growth. The data points to the growing commercial relevance of mobile esports, particularly in regionally driven ecosystems that do not rely solely on international tentpole events.
Another key finding of this year’s report is the significant impact of calendar and format changes on the overall betting performance, directly leading to increased opportunities for operators to bring in more handle over the course of the year. LoL’s 46% volume growth and 32% bet count growth could be attributed to the addition of a new international event and format innovations – both of which point to the growing demand by bettors for more engaging offerings.
Founded in 2018, Oddin.gg has grown alongside the esports betting market, combining an advanced infrastructure, innovative engagement solutions, proprietary modelling and a trading team that includes former esports professionals. Today, more than 300 operators and platform providers globally rely on its fully end-to-end esports betting ecosystem, spanning odds feed, risk management, iFrame solutions, widgets, 24/7 content, Bet Builder and interactive engagement products such as BetPeek, Penalty Arena and AI Avatars. The scale and diversity of that global network provide the data foundation behind the review’s conclusions.
Marek Suchar, co-founder and managing director at Oddin.gg, said: “Billions of bets flow through the Oddin.gg network annually, giving us a read on esports betting that’s hard to get anywhere else. What we saw in 2025 is that esports stopped behaving like a single vertical. The growth rates might look similar across titles, but what drives that growth is completely different. If operators continue to treat esports as one category, they’ll miss where the real leverage is. The next stage of growth comes from understanding the differences and building around them.”
