Denny Hamlin is involved in a federal antitrust lawsuit against NASCAR, filed by 23XI Racing (co-owned by Hamlin and Michael Jordan) and Front Row Motorsports. They allege NASCAR’s charter system and related agreements restrain trade and harm competition. A key development has been ongoing litigation, including a recent appellate ruling and ongoing negotiations toward settlement, with the parties pursuing or considering mediation and potential trial dates set for December 1, 2025. The core question driving the dispute centers on whether NASCAR’s charter framework unfairly limits competition and affects teams’ access to races and revenue. If you’d like, I can summarize the timeline of the case, the main legal arguments, and the latest status from reputable sources, with up-to-date references.
