Online gambling operator Sky Betting & Gaming (SB&G) has confirmed its status as a major UK player with the release of its fiscal 2017 report card.

Figures released Wednesday show SB&G generated revenue of £516m in the 12 months ending June 30, a 38% rise over the previous year’s sum and more than twice the £248m generated in fiscal 2015. Earnings were also up 38% to £146m.

SB&G reported 2.6m registered customers across its five betting and gaming brands, 31% more than the previous year. The company cited Kantar research indicating that nearly one-third (32%) of the UK’s monthly online gamblers are now using SB&G brands.

The customer growth helped push sportsbook stakes up 40% year-on-year to £3.4b, more than twice the £1.5b that Sky Bet handled in fiscal 2015. Average revenue per user rose 5% to £201.
