LexisNexis
From AltData.wiki, The Alternative Data Encyclopedia
LexisNexis is an American data analytics company headquartered in New York City and a subsidiary of RELX, formerly Reed Elsevier. Its products are databases accessed through online portals, including computer-assisted legal research, news search and consumer and public-records information; as of 2006 it held what was described as the world's largest electronic database for legal and public-records-related information.[2][4].
The company's web presence is organized around two main businesses: Legal & Professional Solutions for law firms, corporations, government agencies and academic institutions, and Risk Solutions providing data analytics for compliance, fraud detection, identity and risk decisioning.[1]
History
The LEXIS service was created by Mead Data Central, emerging from the Ohio Bar Automated Research project, and was publicly launched on April 2, 1973 with libraries of New York and Ohio case law and federal tax materials. The NEXIS news database was added in 1980, the year LEXIS completed its hand-keyed database of all extant U.S. federal and state cases.[2]
In December 1994 Mead sold the business to Reed Elsevier for $1.5 billion, and it was renamed LexisNexis. The company later acquired the citation service Shepard's (1998) and, through its parent's $3.6 billion purchase of ChoicePoint in 2008, formed LexisNexis Risk Solutions. In February 2020 LexisNexis migrated its database services to the Amazon Web Services cloud and retired its legacy mainframes, and in 2025 it launched Protégé, a personalized AI-powered legal assistant.[2]
Products
Legal products include case law, statutes, court documents and law journal libraries for jurisdictions including the United States, United Kingdom, France, Australia and Canada, along with practice tools such as Lexis for Microsoft Office. In the UK the company publishes under the Butterworths and Tolley marks, including Halsbury's Laws of England and the All England Law Reports.[2]
Risk Solutions products cover areas such as fraud detection, identity resolution and investigation support for companies and government agencies.[1] The RELX ecosystem also includes securities-disclosure research through Intelligize, whose platform operates within LexisNexis.[3]
Data and Methodology
LexisNexis aggregates licensed and public sources: legal documents and case law, newspaper and news-wire content in the Nexis archive, and consumer and business records assembled for risk analytics. Services are delivered through subscription portals.[2]
Buyers and Use Cases
Core customers are legal professionals, compliance and risk teams, journalists and researchers, and government agencies. In alternative-data contexts, LexisNexis content is used for news and event histories, corporate legal records and public-records enrichment rather than as a trading signal in itself.[1][2]
Landscape
LexisNexis is one of the largest incumbents in legal and public-records information, with Westlaw (Thomson Reuters) as its principal legal-research competitor. Its scale contrasts with specialist alternative-data vendors, though it competes with them in adjacent areas such as filings analytics and entity data.[2]
