The accelerated digitalization of financial systems, intensified by the strategic integration of artificial intelligence (AI), marks a profound paradigm shift in the global financial architecture. FinTech has evolved beyond its initial role as a driver of operational efficiency, emerging instead as a structural force to reshape economic systems, institutional arrangements, and social interactions. In this context, the present Special Issue brings together original and rigorous academic contributions that examine how innovative financial instruments and AI technologies are transforming banking, payment infrastructures, financial governance, and pathways toward sustainable development.

The articles included in this Special Issue adopt interdisciplinary perspectives that intersect finance, economics, data science, public policy, and ethics. Collectively, they highlight both the transformative potential of FinTech and AI and the systemic challenges associated with rapid digital transformation, including regulatory uncertainty, ethical risks, and institutional adaptation.

1. Thematic Directions and Scholarly Contributions

The thematic directions outlined in this Special Issue reflect the multidimensional nature of contemporary FinTech ecosystems and the growing interdependence between technological innovation, institutional transformation, and sustainable development. Rather than addressing isolated technological applications, the contributions collectively illustrate how artificial intelligence, digital financial infrastructures, and decentralized technologies interact across markets, institutions, and societies. From predictive analytics and risk management to banking transformation, financial inclusion, blockchain governance, and sustainability-oriented finance, the selected studies form an integrated analytical framework that captures both micro-level mechanisms and macro-level systemic effects. This structure enables a comprehensive understanding of how FinTech and strategic AI integration simultaneously reshape financial performance, regulatory paradigms, ethical considerations, and long-term development trajectories in diverse economic contexts.

1.6. FinTech, Artificial Intelligence, and Sustainable Development

In contribution 16, an integrative sustainability perspective is provided by Vasile V., Manta O. who examined the bidirectional relationship between FinTech, AI, and sustainable development. Their analysis highlights how digital financial technologies can support ESG objectives, green finance, and social inclusion, provided that technological innovation is aligned with coherent public policies and institutional support.

In contribution 15, this perspective is further reinforced by Zakia Siddiqui and Claudio Andres Rivera who developed a triangulated analytical framework for assessing sustainable FinTech models in Latvia, integrating Rogers’ Innovation Diffusion Theory (IDT), De Meyer’s Innovation Ecosystem framework, and Value Chain Theory. Their empirical findings show that the main competitive advantages of FinTech lie in flexibility, speed, customer-centricity, and trialability, while the main barriers remain regulatory complexity, uneven digital infrastructure, and institutional unreadiness. The study also emphasizes that strong collaboration among ecosystem actors supports innovation diffusion, but proactive regulatory engagement remains limited. Importantly, the authors argue that sustainable FinTech development depends not only on technological innovation itself, but also on institutional readiness, infrastructure capacity, agile public policy, and ESG integration. Their framework offers a replicable model for evaluating FinTech sustainability in small and highly regulated markets, demonstrating that long-term digital financial transformation requires a balance between innovation, compliance, and responsible governance.

2. Conclusions and Outlook Toward the Next Special Issue

The contributions assembled in this Special Issue provide compelling evidence that the strategic integration of FinTech and artificial intelligence represents a structural transformation of contemporary financial systems rather than a transient technological trend. Across diverse methodological approaches and geographical contexts, the studies demonstrate that AI-driven financial technologies are reshaping decision-making processes, risk assessment frameworks, institutional performance, and the architecture of financial intermediation. Collectively, the findings underscore the growing centrality of data-driven intelligence, digital infrastructures, and platform-based models in redefining how financial value is created, distributed, and governed.

Importantly, the insights generated in this Special Issue reveal that the impact of FinTech and AI extends well beyond efficiency gains and cost reduction. Several contributions highlight the emergence of new systemic interdependencies between financial institutions, markets, regulators, and users, raising fundamental questions related to transparency, algorithmic governance, ethical responsibility, and financial stability. At the same time, the evidence presented suggests that, when supported by adaptive regulatory frameworks and inclusive digital infrastructures, FinTech innovations can act as powerful enablers of financial inclusion, institutional resilience, and sustainable economic development.

These findings naturally open the path toward a broader and more integrative research agenda, addressed in the forthcoming Special Issue AI × DeFi × Sustainability: Redesigning the Operating System of Global Finance. While the current volume has primarily examined the strategic role of AI within evolving FinTech ecosystems, the next Special Issue advances the discussion by explicitly focusing on the convergence of artificial intelligence, decentralized finance (DeFi), and sustainability principles as a foundational redesign of the global financial “operating system.” This shift reflects a transition from digitally enhanced financial systems toward intelligent, decentralized, and sustainability-oriented financial architecture.

The upcoming Special Issue aims to examine how this convergence is fundamentally transforming financial institutions, markets, and payment systems, while simultaneously supporting long-term economic, social, and environmental sustainability. In this context, AI-driven analytics, decentralized financial infrastructures, and sustainable finance frameworks are no longer treated as parallel developments but as mutually reinforcing components of next-generation financial ecosystems. Such architectures challenge traditional models of intermediation, governance, and trust, introducing new paradigms based on algorithmic coordination, distributed consensus, and embedded sustainability metrics.

By encouraging interdisciplinary research that spans finance, economics, data science, blockchain studies, and public policy, the next Special Issue seeks to advance scholarly understanding of both the opportunities and challenges associated with this convergence. Contributions are expected to explore how FinTech innovations contribute to resilient, inclusive, and responsible financial ecosystems, while also addressing critical issues related to systemic risk, regulatory design, ethical AI, and the environmental footprint of digital finance.

In this sense, the present Special Issue establishes the conceptual and empirical foundation for the next stage of inquiry. Together, the two Special Issues form a coherent scholarly trajectory that moves from the strategic integration of AI in FinTech toward a deeper exploration of how AI, DeFi, and sustainability jointly redefine the future of global finance. This continuity not only strengthens academic discourse but also provides valuable insights for policymakers, financial institutions, and technology developers seeking to navigate—and shape—the rapidly evolving financial landscape.:
