Founder Thomas Peterffy remains Chairman and key strategic voice; CEO Milan Galik has three decades at the company and became CEO in 2019. The team is deeply technical and frugal, consistent with the firm’s culture. Alignment is strong through controlling noncontrolling interests at IBG LLC, albeit with governance complexity.

Execution through market events, including handling of idiosyncratic losses (e.g., a 2024 NYSE anomaly) and continued platform enhancement, supports confidence. We deduct a few points for key‑person and control risk typical of founder‑controlled structures.
