Artificial Intelligence and Market Abuse Legislation presents a wide-reaching interdisciplinary examination of the impact of AI on the EU Market Abuse Regulation (MAR).Assessing the principles and rules governing the MAR disclosure regime as well as the mechanisms of market manipulation, Filippo Annunziata examines the important role of AI systems in the prompt disclosure of inside trading information. The author analyses the threat of breaches in disclosure protocol posed by technological malfunctions, as well as the opportunities and drawbacks presented by market manipulation in algorithmic trading. This incisive book goes on to argue for greater trading venue monitoring and the installation of adequate systems that can analyse, predict and thus anticipate situations that result in market manipulation.A state-of-the-art study analysing the impact of AI in relation to MAR from both a disclosure regime and an algorithmic trading perspective, this book will be critical reading for researchers interested in the law on AI, and in the regulation of global financial trading and market regulation. It will also be of interest to practitioners and policymakers working in the global financial sector.
