This article introduces and then examines a novel antidoping policy mechanism, based upon a conditional superannuation fund for professional athletes. It begins by presenting a theoretical case in favor of the scheme relative to the background of current policy. Consideration is given to the utility and benefits of a conditional superannuation mechanism to augment existing antidoping policy structures. The case is developed using results from a pilot experimental economics study testing the policy proposal, which suggests that the conditional superannuation mechanism has the potential to outperform existing measures, such as fines and bans. This article offers a policy variation that could supplement the existing arrangements as a contiguous mechanism. While no single policy intervention seems plausible in fully eliminating sport doping, a combination of incentive and punitive mechanisms may yield a superior policy mix to help attenuate doping’s prevalence in elite sport. The evidence presented here within the antidoping policy context may also recommend the utility of conditional superannuation as a mechanism to address other enduring challenges in sport, such as violence, gambling, and behavioral transgressions.
