Bet365 are privately owned by Coates, her brother and fellow joint chief executive John, and father Peter. Last year the family topped the British taxpayer list according to the Sunday Times. The company also made a contribution of 100m to the Denise Coates Foundation charity.

For example, Bet365 was taken to court for refusing to pay over 1 million in winnings to a horse bettor in Northern Ireland in 2024. The company refused a payout of 54,000 to a customer in England in 2024, a case which was still ongoing in 2024.
