Abstract
The integrity of the market and investor con- fidence are seriously threatened by the prolif- eration of financial misinformation via digital media. Existing approaches such as fact check, lineage detection and others have demonstrated significant progress in detecting financial mis- information. In this paper, we present a novel two-stage framework leveraging large language models (LLMs) to identify and explain finan- cial misinformation. The framework first em- ploys a GPT-4 model fine-tuned on financial datasets to classify claims as “True,” “False,” or “Not Enough Information” by analyzing rel- evant financial context. To enhance classifi- cation reliability, a second LLM serves as a verification layer, examining and refining the initial model’s predictions. This dual-model approach ensures greater accuracy in misinfor- mation detection through cross-validation. Beyond classification, our methodology empha- sizes generating clear, concise, and actionable explanations that enable users to understand the reasoning behind each determination. By com- bining robust misinformation detection with interpretability, our paradigm advances AI sys- tem transparency and accountability, providing valuable support to investors, regulators, and financial stakeholders in mitigating misinfor- mation risks.
