Summary

Financial institutions are shifting from siloed AI models to unified transaction foundation models built on transformer architectures, as demonstrated by NVIDIA's report and Revolut's PRAGMA model, which improves fraud detection, credit scoring, and recommendations while reducing feature engineering effort.

<div id="bsf_rt_marker"></div>Financial institutions have spent years building AI: fraud models, credit models, recommendation engines and risk systems. While this sprawl of task-specific models has been effective, it’s also constrained by siloed systems. Siloed systems prevent institutions from developing a unified understanding of consumers’ financial behavior. As enterprise datasets keep growing, so does the gap between what institutions know and what their AI can reason over — creating a major opportunity for the industry to build intelligence using proprietary data. NVIDIA’s <a target="_blank" href="https://www.nvidia.com/en-us/industries/finance/ai-financial-services-report/">2026 State of AI in Financial Services</a> report shows 65% of institutions now use AI, with nearly 90% deploying or assessing it and almost all maintaining or increasing spend. But as AI scales, so does complexity, and fragmented model architectures become the limiting factor. Leading firms are tackling this challenge by rethinking the architecture itself. Where the industry once relied on statistical and machine learning algorithms purpose-built for each line of business, transformer-based transaction foundation models now make it possible to learn a single, unified representation of consumer behavior trained entirely on proprietary data. Transaction foundation models are large-scale AI systems trained on billions of financial events — such as payments, transfers, product interactions and behavioral signals — that transform raw data into intelligence, helping firms better serve their customers. The shift is structural. A traditional fraud model evaluates isolated signals. A foundation model interprets behavior in context where timing, device, location and prior activity shape meaning. More importantly, it brings the power of transformer architectures to tabular data, extracting signals previously invisible to traditional algorithms. A payment at midnight means something different when it’s the fourth in 10 minutes, on an unfamiliar device, in a city the customer’s never transacted from before. That contextual depth improves performance across tasks, not just within them. In collaboration with NVIDIA, Revolut built<a target="_blank" href="https://arxiv.org/pdf/2604.08649"> PRAGMA</a> — a family of transformer-based foundation models trained on 24 billion events across 26 million user records spanning over 100 countries.

Financial services firms can also work with services partners EXL, Infosys, GFT IT Consulting and Thoughtworks to apply the developer example to their specific use cases. EXL is integrating transaction foundation models into its EXLerate.ai platform to unify siloed financial data into a scalable, enterprise intelligence layer powered by proprietary transaction data. In collaboration with NVIDIA, EXL is using this architecture to help financial institutions accelerate model development, enhance contextual decisioning and operationalize agentic AI at scale. Thoughtworks is helping financial institutions operationalize transaction foundation models within complex banking environments, integrating them into payment, servicing and risk while establishing the necessary governance and AI operating models. The company will be showcasing a demo and presentation on transaction foundation models at the upcoming AWS Summit in New York City on Wednesday, June 17. GFT IT Consulting is integrating transaction foundation models into its flagship solutions: Wynxx, an agentic AI platform used by over 100 financial institutions for secure AI adoption in areas like credit risk, and Smaragd, a compliance engine that reduces false positives by up to 75% for major banks. Join NVIDIA at Money20/20 Europe from June 2-4 to learn how transaction foundation models are powering the next generation of AI in financial services.
