Why Financial Services Needs AI-Ready Infrastructure
AI is no longer a test bed in finance. It's core infrastructure. More than half of industry leaders treat it as a strategic priority, and nearly 98% plan to increase investments in AI infrastructure by 2025, according to the NVIDIA 2025 Financial Services AI Report.
The takeaway is simple: speed, security, and scalability now decide winners. Institutions that modernise their data centres for real-time AI workloads will see faster insights, lower risk, and new revenue. Those that stall will feel it on P&L and market share.
What the leaders are doing
"Generative and agentic AI will reshape competitive dynamics across every industry, and we are embracing these tools as we have embraced robotic process automation and machine learning for years," says Charlie Scharf, Chairman and CEO of Wells Fargo. "The past year has been exciting as our world-class technology team has led us in building the technical foundation, training over 90,000 employees, deploying AI tools to over 180,000 desktops and we are now beginning to implement use cases more broadly."
This isn't experimentation. It's scale. And it starts with the right infrastructure.
Speed at the speed of markets
Markets don't wait for batch jobs. High-frequency trading targets sub-millisecond latency. Fraud detection has to process millions of transactions in real time. Algorithmic models need terabyte-per-second throughput to stay ahead of the tape.
Generic IT stacks can't meet those demands. Delayed fraud alerts, failed transactions, or slow model inference can trigger losses, reputational damage, and regulatory heat. Speed and resilience are now operational requirements.
The hybrid reality (done right)
Cloud-only doesn't fit every financial workload. Data residency, regulatory obligations, and internal risk policies keep sensitive data on-prem. At the same time, the cloud is useful for experimentation, retraining, and burst capacity.
The practical answer is hybrid: keep regulated data and mission-critical inference on-prem, and use cloud for elastic compute. That requires GPU infrastructure that spans both environments, unified orchestration, and native support for leading AI frameworks and tools.
Compliance by design
Regulators expect controls to be built into the stack, not bolted on. Encryption everywhere, role-based access, immutable audit logs, and data residency controls must be part of the baseline architecture. Standards like PCI-DSS and laws such as GDPR directly shape how you build and operate.
The best shops treat compliance as a feature. Event-driven architectures trigger AI workflows in response to live transactions and market signals, with full traceability for auditors. That reduces risk and speeds delivery.
"Agentic AI represents a step-change in how financial services organisations operate and innovate," says Matt Cloke, CTO at Endava. "The opportunity is clear, but so is the responsibility. Our research shows that those who build AI-native operating models, backed by strong governance, will be the ones to lead the next era of financial services."
An infrastructure checklist for finance teams
- Latency: Sub-millisecond targets for trading and authorisation paths; prioritise high-bandwidth, low-jitter interconnects.
- Throughput: NVMe, RDMA, and high-speed fabrics to feed GPUs without bottlenecks.
- Compute: GPU-accelerated clusters sized for training, fine-tuning, and low-latency inference.
- Orchestration: Unified scheduling across on-prem and cloud with workload-aware placement and cost controls.
- Data: Feature stores, vector databases, and streaming pipelines with schema governance and lineage.
- Security: Zero-trust principles, HSM-backed key management, tokenisation, and least-privilege access.
- Compliance: Built-in auditability, data residency controls, and model governance tied to policy.
- Observability: End-to-end monitoring for data drift, model performance, SLOs, and cost per prediction.
- Resilience: Active-active architectures, rapid failover, and tested incident response for AI pipelines.
- People: Upskill engineers, quants, and risk teams to operate AI-native platforms, not just use AI features.
Why this matters now
AI is changing how firms compete. Product differentiation is coming from models that learn faster, detect risk earlier, and serve clients with precision. Without the right infrastructure, those models never make it to production-at least not safely or profitably.
The institutions that move first will create advantages that are hard to copy: better spreads, lower fraud losses, faster onboarding, and tighter capital allocation. The ones that delay will pay twice-once in tech debt, and again in lost opportunity.
Next steps for finance leaders
- Benchmark latency, throughput, and GPU utilisation against target workloads.
- Prioritise use cases with measurable ROI: fraud, credit decisioning, trade execution, AML, and customer service.
- Stand up a governed hybrid platform with shared services: security, data, orchestration, and observability.
- Build a cross-functional working group (Tech, Risk, Compliance, Business) to accelerate approvals and reduce rework.
- Plan for cost transparency: track cost per model, per prediction, and per business line.

The path forward
AI-ready infrastructure is no longer a nice-to-have. It's a prerequisite for real-time decisioning at market pace-and a clear lever for growth and risk control.
