This study examined the influence of artificial intelligence (AI) in fostering regional integration in the Economic Community of West African States (ECOWAS). The research achieved three objectives. It examined how artificial intelligence affected efforts at regional integration, evaluated its influence on economic diversification and identified the risks and challenges of using AI in the subregion. Descriptive-analytical research with secondary data was applied. The results show that artificial intelligence is a transforming agent in the economy of ECOWAS member countries. AI technologies are aiding digital shift in trade, health care, and governance sectors while helping economies become less dependent on traditional fields like agriculture and mining. Also, AI aids e-government efforts, making it easier for governments to communicate with citizens and improve governance. AI is important for changing the economy by boosting productivity and innovation in farming, healthcare, and finance. It improves resource utilization, supports data-driven decision-making, and helps resolve challenges related to regional integration by enhancing cross-border transactions and communication. In addition, the study identified significant risks, including job displacement, especially in low-skilled sectors, the digital divide, and trust issues in AI systems. These issues show the need for educational programs to boost AI knowledge and digital skills. The study concludes that AI presents excellent potential for regional and economic development in ECOWAS, but its success depends on addressing infrastructure, skills, and governance challenges.
