The rapid growth of esports has transformed competitive gaming into a global digital sports industry involving professional players, tournament organizers, and millions of spectators. However, this expansion has also introduced new challenges related to competitive integrity, particularly through the emergence of e-doping. E-doping refers to the use of technological or pharmacological interventions, including artificial intelligence-assisted software tools, automated scripts, and cognitive performance-enhancing substances, to gain unfair advantages in esports competitions. This study examines the legal and governance implications of AI-enabled cheating in esports and evaluates the adequacy of existing regulatory mechanisms designed to protect fair competition. Employing a mixed-method research design, the study combines doctrinal legal analysis with an empirical stakeholder questionnaire survey to assess perceptions regarding the prevalence and regulation of e-doping. The findings highlight significant regulatory gaps in esports governance and emphasize the need for stronger international cooperation, improved anti-cheat technologies, and clearer legal frameworks to safeguard integrity in digital sports.This paper argues that existing esports governance frameworks are structurally inadequate to address AI-enabled e-doping, and that the absence of binding contractual player protections, independent dispute resolution mechanisms, and a supranational regulatory authority constitutes a critical legal deficit requiring urgent reform. A central contribution of this paper is a principled legal distinction between permissible AI-assisted training and prohibited AI-enabled competitive cheating, which provides a normative foundation for future regulatory design..
