Bets on eSports accept both traditional and specialized bookmakers. Action line is usually not very rich at fundamental companies. Hence, players usually turn to cybersports bookmakers.
The most famous example of a sports bookmaker with bets on eSports is Pinnacle Sports. For example, in 2015 this company became the official sponsor of the Russian eSports Team Empire.
Egamingbets and Gamebets are popular, too.
The action line even at eSports bookmakers is relatively narrow compared to betting on sports at fundamental bookmakers. It is often limited to bets on a match result and Asian handicap.
