1. Introduction

The hedge fund industry, managing over $5 trillion in assets [1], is undergoing a technological revolution driven by generative artificial intelligence. Since the launch of ChatGPT in 2022, 86% of hedge fund managers now grant staff access to AI tools [2], with adoption accelerating dramatically in 2024-2025 [3]. This paper synthesizes findings from 50 academic and industry sources to analyze how generative AI is transforming hedge fund operations, investment processes, and competitive dynamics.

The convergence of artificial intelligence and quantitative finance is reshaping investment management, with Generative AI (GenAI) emerging as a disruptive force in hedge fund operations. GenAI models, including large language models (LLMs), generative adversarial networks (GANs), and foundation models, offer new capabilities in interpreting unstructured financial data, automating analysis, and generating predictive signals. Despite growing interest, the practical integration of GenAI into hedge fund workflows remains an open challenge, especially in aligning data architectures, risk controls, and decision-making processes.

The hedge fund industry is experiencing a technological revolution, with Generative AI (GenAI) at the forefront of this transformation [4]. GenAI’s capabilities extend beyond traditional machine learning, enabling advanced portfolio optimization, predictive analytics, and the automation of complex tasks. As asset managers seek an edge in increasingly competitive markets, the adoption of GenAI tools is accelerating [5].

Our goal is to provide a reference architecture that supports scalable data ingestion, robust feature engineering, responsible AI modeling, and intuitive output interfaces. Figure 1 visualizes the diverse sources of literature and data types surveyed, emphasizing the academic and industry landscape shaping this proposal. Figure 7 outlines the modular pipeline—from data preprocessing to user-facing APIs—while highlighting the role of governance and security. A more detailed dataflow in Figure 5 maps structured and unstructured inputs to AI-driven outputs, connecting risk management, operations, and portfolio insights.

The remainder of the paper is organized as follows. This works surveys relevant GenAI applications in financial domains. We also introduces the proposed architecture with rationale for each layer. We also explores hedge fund use cases enabled by this architecture. We offer offers insights on implementation challenges, compliance, and model explainability. We conclude in with directions for future research and deployment.
