"Computational antitrust” consists of using legal informatics (i.e., computational tools—such as AI and blockchain—applied to the legal field) to assist competition procedures and analyses. On the one hand, it benefits companies by increasing their ability to anticipate the anti-competitive effects of their practices and comply with competition rules. On the other hand, it allows competition agencies to speed up and improve their analyses, thus bringing more companies to comply with these rules. Overall, computational antitrust seeks to increase the level of legal certainty and accuracy of decisions, therefore benefiting both companies and agencies.
