Online gambling operator Kindred Group saw revenue rise nearly one-third in the second quarter of 2018 as customer activity hit an all-time high.

Wednesday saw the Stockholm-listed Kindred release its unaudited interim report for the second quarter and first half of 2018, which showed gross winning revenue of £219m in the three months ending June 30, up 31% from the same period last year. Earnings improved by one-quarter to £41.7m while after-tax profits rose one-fifth to £25.5m.

The company credited excitement over the first half of the 2018 FIFA World Cup for generating “a significant all-time high in customer activity,” with active customer ranks hitting 1.55m during Q2. This, coupled with “unexpected results” at the World Cup, pushed sports betting margins (after free bets) to 8.2%.

Kindred says the good times have continued into Q3, with average daily gross winnings revenue through July 22 rising 29% year-on-year. Despite the positive news, the company’s stock price dipped nearly 13% following the report.
