Abstract

Big data analytics has emerged as a transformative tool in the financial services industry, particularly in the United States, where institutions manage trillions of dollars in daily transactions. This study explores how financial institutions leverage big data analytics for risk 08 Jul 2025 (Published Online) management, with a specific focus on fraud detection and prevention. By integrating advanced Big Data Analytics; Financial Fraud; real-time processing of vast datasets to uncover hidden patterns, identify anomalies, and predict Fraud Detection; Machine Learning; potential threats. Traditional fraud detection methods often fail to address the growing Risk Management; USA; Financial complexity and sophistication of financial crimes. In contrast, machine learning models like Services; Data Privacy. Logistic Regression, Decision Trees, and Random Forests provide robust solutions by offering enhanced predictive accuracy and adaptability to evolving fraud tactics. This study examines a dataset comprising demographic, transactional, and geographical features, which are analyzed using machine learning algorithms. In order to guarantee fair and reliable fraud detection systems, the report emphasizes the need to strike a balance between regulatory compliance and technical improvements.
