Jockey Club updates past performances data after vets' list exposure

The Jockey Club said past performances distributed by an unknown party contained veterinarian’s list information, a disclosure that puts a sharper edge on how bettors read a horse’s recent form and whether health-related data in the line can change confidence before a race.

In a June 20 statement, The Jockey Club said its InCompass Track Manager software is used by racetrack personnel and veterinarians to access third-party horse-health information, and that access to veterinarian’s list information is tightly controlled. The organization said some of the vet’s list details that appeared in a pair of past performances were not available through Track Manager, and it was unclear whether Track Manager had been used at all.

The betting significance is straightforward. Past performances already shape how horseplayers judge layoffs, workout patterns, shipping, and recent effort. If vet’s list data begins appearing alongside a horse’s running lines, it can change the way a runner’s recent record is interpreted on a card, especially in situations where a short-priced contender suddenly looks less secure or a comeback horse appears more logical than the raw running lines suggest. That makes the source of the information as important as the information itself.

The Jockey Club also said InCompass does not provide computer-assisted wagering operations with access to any information or data, and that it had not identified any unusual, unauthorized, or suspicious activity so far. It said it would continue working with HISA and racetrack partners on possible additional safeguards around access to veterinarian’s list information.

The broader backdrop is already in motion. HISA has announced a comprehensive review of veterinarian’s list and stewards’ list categories across U.S. Thoroughbred racing, with changes targeted for 2026. It also began requiring, in June 2024, that horses shipped from Louisiana to tracks in other states be placed on the HISA veterinarian’s list as medically compromised and unfit to race.

That leaves the wagering market facing a more visible health layer in the records that power handicapping. The Jockey Club and Equibase remain central data providers in North American racing, with Equibase describing itself as the official source for race results, mobile racing data, statistics and past performances, while Daily Racing Form, Horse Racing Nation and other services continue to sell past performances as a core betting product. BloodHorse said on June 26 that The Jockey Club was continuing its investigation into misuse of vets’ list information provided to racetracks and regulators for official duties.
