Britain's betting scene could be in for a huge shake-up after a report the Coates family are considering a sale of bet365. Their online gambling empire could be valued at £9 billion. The Guardian reports that bet365, which is headed by Denise Coates, has held talks with Wall Street banks and US advisers about a full or partial sale. It is suggested that one option is a medium-term plan to float the business on a US stock exchange. Another is a partial sale to a private equity investor, with the Coates family retaining a stake before an eventual listing. Any move to sell bet365 would cause anxious moments for racecourse executives as it is a massive supporter of the sport through its big programme of race sponsorship. In April alone the bet365 Gold Cup, which brings the curtain down on the jumps season, was the highlight of its backing of a two-day meeting at Sandown, while Field Of Gold is favourite for this weekend's 2,000 Guineas after his win in the bet365 Craven Stakes at Newmarket. Similarly, Desert Flower is favourite for the 1,000 Guineas on the back of her success in the bet365 Fillies' Mile. Among many other races backed by bet365 are the Cambridgeshire, the Morebattle Hurdle, the Charlie Hall Chase and the Lancashire Oaks. Bet365 has also recently become a major sponsor of greyhound racing.
