News Summary:
Details emerged on October 1, 2026, from leaked regulatory documents from Curaçao, revealing that SIS, a racing live feed supplier whose shareholders include leading UK-licensed bookmakers, signed a B2B deal in 2022 with black-market operator Santeda. The arrangement, potentially still active this year, has angered its biggest shareholder, Entain. These revelations align with broader reporting on the same day that three UK bookmakers, who have warned against illicit markets, also profited from lucrative deals with one of the world’s largest offshore casinos, with these arrangements similarly emerging from the recent Casino Secrets leak. On September 28, the Racing Post/SIS Betting Shop Manager of the Year competition confirmed its Top 16 managers following mystery shopper visits to the Top 32. Previously, on September 17, Greyhound Racing Ireland announced Enniscorthy Greyhound Stadium was scheduled to debut on the SIS platform from October 1, subject to final preparations, introducing a new tea-time evening racing slot for national and international betting audiences. Earlier, on August 21, SIS began distributing live racing from Sandy Ridge Racing, Kentucky’s first dedicated Quarter Horse track, to its global network of operators, starting from the track's August 19 opening.
