B a c k g r o u n d . Artificial intelligence (AI) is a powerful driver of innovative transformation and proactive service delivery, generating demand based on the use of personalized information that clients can access in real time. The implementation of integrated solutions based on generative artificial intelligence (GenAI) and blockchain technologies lays the foundation for a synergistic effect through the transformation of traditional approaches M e t h o d s . To identify forms of integration and reveal the synergy between artificial intelligence and blockchain technologies in the financial sector, a combination of methods was applied, including expert assessment, analysis and synthesis, hierarchy structuring, rating, decomposition, and multicriteria analysis. Drawing on data from BIS, McKinsey & Company, and Deloitte, the benefits of implementing integrated GenAI and blockchain-based solutions were highlighted in terms of enhancing the transparency, security, and efficiency of financial operations and transactions. Based on methodological approaches from the IMF, OECD, Financial Stability Board, and the World Economic Forum, key areas for the practical application of integrated AI and blockchain solutions in the financial sector were identified. R e s u l t s . The article presents the evolution of artificial intelligence during 2022–2025 and defines its main models. It analyzes the costs of implementing AI platforms across different sectors of the economy and characterizes the main forms of integration of artificial intelligence and blockchain technologies in the financial sector, such as smart contracts, fraud and cyber threat detection, credit scoring and risk assessment, automation of financial processes, trading, and asset management. The benefits and risks of AI–blockchain synergy were outlined depending on the application domain. Particular attention is given to strengthening Ukraine's institutional readiness to adopt AI in the financial sector. The results obtained may be used in strategic planning for the digital development of the financial sector under the growing influence of technological innovation. C o n c l u s i o n s . The combination of GenAI and blockchain technologies generates a synergistic effect that acts as a catalyst for innovation in the financial sector, particularly in the areas of security, efficiency, and personalization of financial services. At the same time, the integration of GenAI and blockchain introduces a range of challenges related to scalability, system interoperability, and the management of decentralized structures, which require comprehensive implementation of OECD principles regarding the development and ethical use of AI, harmonized standards, and the creation of a flexible regulatory environment.
