Abstract Online marketplaces’ expansion has completely transformed the way in which products and services are traded, benefiting both consumers and companies in a variety of ways. However, the decentralized nature of online markets, the problem of market domination, and the growing use of big data in digital marketplaces, has brought many difficulties related to competition law. Further complicating matters is the growth of platform-to-business (P2B) partnerships. This manuscript discusses recent competition cases involving online platforms and offers an outline of the difficulties faced by competition authorities in dealing with competition concerns in digital markets. The specific applicability of Articles 101 and 102 of the Treaty on the Functioning of the European Union to concerns involving digital platforms will be thoroughly examined. There will also be discussion of potential fixes for the concerns mentioned. The study outlines the raised concerns and offers potential solutions. Thus, it will provide a glimpse into a potential future strategy that the European Union competition authorities, including the Commission and National Competition Authorities, may adopt about online platforms.
