What Thomson Reuters does

Thomson Reuters Corporation is a Toronto-headquartered, publicly traded (TSX/Nasdaq: TRI) information services and AI-software company that delivers content, workflow tools, and AI-enabled assistants to professional markets including legal, tax, accounting, audit, compliance, risk, news, and international trade. The modern corporation was formed in 2008 when Thomson Corporation acquired Reuters Group; after divesting its Financial & Risk business to LSEG in 2021, the company has repositioned around AI-augmented professional information, with roots tracing back 175 years to the 1851 founding of Reuters.

The product portfolio is organized around four disciplines: Legal (Westlaw, Westlaw Advantage, Westlaw Edge, Practical Law, CoCounsel Legal, HighQ, Legal Tracker), Tax/Audit/Accounting (CoCounsel Tax, CoCounsel Audit, ONESOURCE suite, Guided Assurance, SurePrep, SafeSend, Additive), Risk & Fraud (CLEAR, Fraud Detect, with a strategic Socure partnership), and International Trade (ONESOURCE Global Trade Management, Global Trade Research AI, Global Classification AI) — supported by Reuters news and the Thomson Reuters Institute. The technology stack centers on CoCounsel (now rebuilt on Anthropic's Claude Agent SDK), a proprietary legal-focused LLM ("Thomson"), and a Fiduciary-Grade AI standard aligned to ISO 27001 and ISO 42001, all grounded in 1.9 billion Westlaw/Practical Law documents and 1.4 billion KeyCite signals curated by 2,700 attorney-editors. The data estate is consolidated on Snowflake across 37,500+ governed tables and 350 sources, and ONESOURCE+ delivers native integrations into Oracle Fusion Cloud ERP, Workday, and SAP.

Revenue is generated primarily through recurring annual subscriptions (Westlaw, CoCounsel, ONESOURCE, CLEAR, Reuters Connect) sold via an enterprise field-sales motion to law firms, corporates, tax/audit firms, and government, supplemented by professional services, ProView e-book sales, and API/data licensing. Q1 2026 reported $2.087B in revenue (+10% YoY) with 8% organic growth; FY2025 revenue was approximately $7.7B. The company is executing an aggressive AI-focused acquisition program (Casetext $650M in 2023, SurePrep $500M in 2023, plus SST, Materia, Additive, and Noetica) alongside Thomson Reuters Ventures, a $150M corporate venture fund launched in February 2025.
