London betting shop coup costs UK bookmakers up to £800,000 on US horse races

On 9 August 2026, five horses from Maryland's Fair Hill Training Center won or placed at Monmouth Park and Saratoga after poor form and long layoffs. Coordinated wagers placed in person across at least 12 London betting shops cost British bookmakers up to £800,000 ($1.08 million), Racing Post reported. HISA is investigating whether the bets were sharp punting or something more serious. No charges have been filed.
