Former insider trader Tom Hardin on the blind spots in finance’s fight against market abuse

Today’s guest is better known to the FBI as ‘Tipper X’, a former hedge fund analyst who became a key cooperating witness in the largest insider trading enforcement sweep in a generation, helping authorities bring cases against more than 80 individuals.

In this episode, he explains why market abuse is rarely a single rogue act. Instead, it’s an incremental process, driven by performance pressure, network drift and the quiet normalisation of ethical grey zones. Drawing on his experience inside a hedge fund, inside a federal investigation and now advising firms and regulators, he argues the industry remains too focused on detecting bad trades rather than preventing bad decisions.

He challenges compliance leaders to look beyond surveillance dashboards, to measure culture as seriously as they measure transactions, and to rethink escalation pathways before misconduct crystallises. And he urges regulators to invest as heavily in prevention and human insight as they do in enforcement technology.

Tom Hardin now works with boards and compliance teams globally, helping them spot the warning signs before misconduct becomes a headline. He is also the author of Wired on Wall Street, which tells the story behind the codename ‘Tipper X’.
