This study examines artificial intelligence-structured investments and the financial performance of deposit money banks in Nigeria using Return on Assets (ROA) as a proxy for financial performance. This study specifically examines the impact of AI software book value, AI software expenses disclosure, AI operational automation using chatbots, and bank size on ROA. This paper uses an ex post facto research design and secondary data from ten purposively selected DMBs listed on the Nigerian Exchange Group from 2015 to 2024. From the empirical analysis, this paper finds that AI software book value, AI software expenses disclosure, and AI operational automation using chatbots have a positive and significant impact on the return on assets of banks in Nigeria. This paper also finds that bank size has a positive impact on return on assets. This paper concludes that AI-structured investments have a significant impact on asset utilization in Nigeria. This paper recommends that banks in Nigeria invest more in AI infrastructure and invest in staff capacity in AI technologies, and that the regulatory authority in Nigeria design guidelines for AI adoption in banks.
