What Is The Driver Of The Large Language Model (LLM) in Legal Market?

The growing volume and complexity of legal documents and regulations are expected to propel the growth of the large language model (LLM) in the legal market going forward. The volume and complexity of legal documents refer to the increasing number, length, and intricacy of laws, rules, and regulatory texts that organizations must interpret and comply with as part of routine legal and business operations. The volume and complexity of legal documents and regulations are increasing due to the rapid expansion of cross-border business operations, which require organizations to comply simultaneously with multiple jurisdictions, evolving regulatory frameworks, and overlapping legal standards. Large language models in legal services support the rising volume and complexity of legal documents and regulations by rapidly analyzing, summarizing, and extracting relevant insights from large sets of statutes, contracts, and case law across multiple jurisdictions, enabling legal teams to manage regulatory complexity efficiently. For instance, in August 2025, according to the Competitive Enterprise Institute, a US-based non-profit organization, data on U.S. Federal Register publications showed that the Federal Register contained 90,402 pages of rules and regulations, up from 80,756 pages in 2022, highlighting the rapid growth in regulatory documentation that legal professionals must manage. Therefore, the growing volume and complexity of legal documents and regulations are driving the growth of the large language model (LLM) in the legal market.
