Large Language Models in Finance: Our Paper at ISBM 2026

Our paper, "Large Language Models in Finance: A Survey of Foundations, Applications, Adoption Strategies, and Open Challenges," was presented at the 5th World Conference on Information Systems for Business Management (ISBM 2026) in Bangkok. It has been selected for publication in the ISBM Conference Proceedings by Springer Nature. It was a privilege to work with my co-authors, Aparna Krishna Bhat and Pankaj Pant. Why we wrote it Financial institutions are no longer asking whether large language models are useful. They are asking how to actually get one. To answer that, a whole family of financial LLMs (FinLLMs) has emerged, and they are built in very different ways. Some are foundation models trained from scratch on proprietary data. Others take an open-source model and fine-tune it at a fraction of the cost. We didn't try to catalog every published system. We organized the field around the decision an institution actually faces: not which model is best in the abstract, but which construction approach fits its own constraints. What the paper covers Foundations: the adaptation techniques behind the differences between models. These range from full fine-tuning, prompt-based methods and instruction tuning to RLHF, parameter-efficient methods like LoRA, and retrieval-augmented generation (RAG). Applications: the finance work FinLLMs are inheriting, not inventing: trading, risk modeling, text mining and advisory. These set the performance baselines any model has to beat. Systems compared: BloombergGPT, FinMA, InvestLM, FinGPT and FinTral. We compare them by how they were built, because that choice drives cost, openness and fit for real deployments. A decision framework: practical guidance for institutions deciding whether to build, fine-tune, or buy. What the evidence says The benchmark picture is mixed. On sentiment analysis and classification, FinLLMs now hold their own against much larger general-purpose models. On multi-step numerical reasoning, they still fall well short, and none of the adaptation strategies we reviewed has closed that gap. The biggest open obstacles are hallucination, knowledge that stops at the training cutoff, and the lack of a shared evaluation framework. So we argue that retrieval grounding, contamination-checked benchmarks, and auditable fine-tuning should come before simply scaling models up. Why it matters to me My day job is helping insurers and financial services firms modernize their core platforms. There, the questions in this paper are concrete: what to build, what to buy, how to govern it, and how to trust the output. This research was another chance to connect academic work with what we see in the industry every day, and to keep learning as AI keeps changing. I'm grateful to my co-authors and to everyone who supported this work. I'll share a link here once the Springer Nature proceedings are published.
