The EU consolidated tape for equities: From inception to reality

This paper describes the search for a single data source on equity trading in the European Union (EU), which concluded at the end of 2025 with the selection of a consolidated tape provider (CTP) by the European Securities and Markets Authority (ESMA). The authors explain how the initial intention to spur market-driven innovation with a voluntary framework embedded in the second Markets in Financial Instruments Directive (MiFID II) from 2014 did not lead to the emergence of a CTP. Instead, the latest review of the Markets in Financial Instruments Regulation (MiFIR), concluded in 2024, opted for a binding selection procedure to appoint a single entity to operate the CTP for a period of five years. This paper then turns to how the evolution of ESMA’s role in establishing the CTP has evolved with this changed paradigm. Having shaped the building blocks of the equity transparency regime and of the equity CTP in technical standards, ESMA is now tasked with ensuring their convergent application, as part of the wider equity transparency rulebook. In running the selection procedure, ESMA has combined the criteria listed in MiFIR and the EU rules on public procurement in an unprecedented approach, striving for transparency and equal treatment between applicants. ESMA’s expertise in the European trading landscape will be leveraged for authorising and supervising the equity CTP. Finally, the authors outline how the CTP is poised to become a game-changer for EU equity markets, where data consolidation may prove even more decisive, due to a more fragmented market landscape in the EU compared to the US. Potential use cases range from increasing the visibility of European markets, remedying the fragmentation of markets and contributing to the creation of a genuine single market for equity trading in the EU, to deepening ex-post analysis of trading patterns to the ultimate benefit of all stakeholders, notably investors within as well as outside the EU.
