Sportingbet, a renowned online wagering operator, is currently owned by Entain plc, a prominent British wagering company. Previously listed on the London Stock Exchange and part of the FTSE SmallCap Index, Sportingbet was acquired by GVC Holdings.

Out of each wager placed through OTB, approximately 77 percent goes into the parimutuel pools for distribution to winning bettors. The remaining amount, known as the "takeout", is retained by the OTB operator. In addition, a surcharge of 5 or 6 percent is deducted from most payouts to winning OTB bettors.
