This study examines the impact of Artificial Intelligence (AI) on performance of listed deposit money banks in Nigeria, focusing on AI-driven fraud detection systems (ADFDS), risk management (RM), and customer satisfaction (CS). This research employs a survey design with data collected from staff and management of 14 listed Nigerian banks, analyzing the relationship between ADFDS, RM, and customer satisfaction. The regression analysis reveals that both AI-driven fraud detection systems and risk management practices have a positive and significant impact on customer satisfaction. Specifically, ADFDS contributes to improving customer trust and satisfaction by enhancing fraud detection, while RM practices bolster customer confidence in banks' ability to manage risks. The study concludes that AI technologies are essential for improving performance in Nigerian banks, particularly in enhancing customer satisfaction. Banks are encouraged to invest further in AI technologies to improve fraud detection and risk management, while also ensuring that these innovations align with customer needs for convenience and security.
