Big Data Meets the Backstretch: The Professor's Edge and HISA's Digital Panopticon
In June 2026, the thoroughbred world was sent spinning when confidential veterinary health data leaked onto social media, displayed within augmented past-performances posted by a horse racing social media rabble rouser. It took weeks of frantic whispers, preliminary denials, and a digital manhunt before the story finally broke wide open: the source of the leak wasn’t an organized crime syndicate or a disgruntled groom, but Dr. Marshall Gramm, a Rhodes College economics professor, founding partner of Ten Strike Racing, and a ubiquitous figure across handicapping contests, claiming ranks, and industry governance committees. Gramm wasn’t just a casual observer; he was a horse owner, bettor, and had a media profile, an “insider” who had spent years analyzing racing information and participating in the very types of high-level industry circles where data privacy and oversight were hammered out.
For weeks after those custom past-performances for Deterministic and Griffin’s Wharf surfaced on X, posted by Justin Wunderler, who then started pulling the thread, HISA’s public line was that nothing had gone wrong on its end. On June 15, CEO Lisa Lazarus said flatly that the data “could not have come from the HISA portal.” It had. Reconstructing what happened took roughly two months of digital forensics, contractor interviews, and a third-party cyber investigation by the firm Arete. On August 17, 2026, HISA filed two disciplinary charges against Gramm, one under the rule governing access to veterinary records and one for fraud.
What tips this from a data-policy case into something stranger is a single scene. On the morning of July 17, Gramm joined an hour-long call convened by The Jockey Club, to which he had been elected in 2024. The subject was the leaked past-performances and whether the industry should start disclosing veterinary records to the public. On the call with him were Lazarus, Patrick Cummings of Mike Repole’s National Thoroughbred Alliance, and Jockey Club executives Jim Gagliano and Charlotte Clément. Gramm offered ideas. He did not mention that he was the reason the meeting was happening. Around 5 p.m. that same day, HISA investigators confronted him, and he acknowledged being the source. Lazarus already knew where the trail led while she sat on the morning call. Nobody else on the call did. A man was helping the industry craft its response to his own leak.
