Financial services firms are leading AI adoption, especially generative AI, focusing on real-world use cases such as fraud detection, claims automation, trading insights, and regulatory reporting. Unlike other sectors, these firms face strict compliance, high security needs, and rising cloud costs, driving a shift toward on-premises or co-location GPU clusters. Proprietary AI models are viewed as critical intellectual property, similar to trading algorithms. Advances in liquid cooling and dense GPU racks are making large-scale infrastructure viable. With agentic AI and supercomputing, financial institutions are set to define the future of intelligent, secure, and efficient financial systems.
