AI-Cafe presents: Exit the Needle, Enter the Haystack: Supervised Machine Learning for Aggregate Data

As in other sectors of our economy, AI has entered the financial trading scene as a real game changer. AI is proposed to deliver several benefits to capital markets, making them faster, more liquid and cost-effective, thus perhaps more efficient. Yet AI-powered trading may expose capital markets to new sources of instability and failure. In the latter regard, increasingly capable and autonomous AI trading systems and strategies threaten market integrity in unique and significant ways.

Focusing on the dark side of AI trading, this talk will address innovative and challenging questions such as: Can AI autonomously discover and perpetrate forms of market manipulation without any prior human intent? And how does existing financial regulation address the risks associated with autonomous, black-box AI? In particular, who will be held liable for damages and crimes committed by AI? How to monitor AI trading behaviour and prevent misconduct? Are financial supervisors able to detect abnormal trading activities and investigate suspected cases of AI-optimized manipulation? In other words, where do financial regulators stand on protecting market integrity in algorithm-dominated capital markets?
