Overview
RELX is a UK-listed information and analytics group spanning Risk, Scientific, Technical and Medical, Legal, Exhibitions, and legacy print. Its moat is strongest in Risk and Legal, where proprietary datasets, authoritative content, AI-enabled tools, and workflow integration support recurring revenue and switching costs. STM combines content rights with ScienceDirect and research workflows, but faces open-access and procurement pressure. In H1 2026, revenue rose 3% to GBP 4.871 billion, underlying growth was 7%, and adjusted operating profit rose 5% to GBP 1.727 billion. Legal underlying revenue grew 10%, Risk 8%, STM 6%, and Exhibitions 6%. Exhibitions remains cyclical and has no independently established segment moat; print is a small declining activity. Privacy rules, open access, AI competition, cybersecurity, and customer procurement remain the main risks.

Data Network Effects
Network
Data Network Effects
Strength
Durability
Confidence
Evidence
Fraud/identity and insurance risk decisioning improve with large proprietary and contributory datasets; RELX describes industry-wide insurance data and broad risk datasets as core to timely benchmarking and analytics.
Data Network Effects moat: definition, examples, and stocks
Erosion risks
- Data privacy/localisation rules reduce data availability or cross-border linkage
- Data breach or model failures reduce trust and trigger churn
- Large platforms/banks develop in-house decisioning stacks using cloud ML and first-party data
Leading indicators
- Digital Identity Network transaction volumes (daily/annual)
- Renewal/retention rates in Business Services and Insurance verticals
- Regulatory actions affecting data sharing (privacy, AML/KYC)
Counterarguments
- Other credit bureaus and risk vendors also have large datasets and model capabilities
- Some customers can multi-source data and commoditise decisioning logic
Data Workflow Lockin
Demand
Data Workflow Lockin
Strength
Durability
Confidence
Evidence
Products are designed to integrate into customer workflows and infrastructure (e.g., underwriting/claims, fraud prevention, AML screening), increasing switching costs and enabling expansion within accounts.
Data Workflow Lockin moat: definition, examples, and stocks
Erosion risks
- API standardisation makes vendor swaps easier
- Procurement pressure forces unbundling of platforms into commodity data feeds
- Model/feature parity reduces differentiation over time
Leading indicators
- Net revenue retention / expansion within top accounts
- Platform adoption metrics (e.g., platform modules per customer)
- Implementation times and integration depth with core systems
Counterarguments
- Some buyers prefer best-of-breed point solutions and integrate them via modern data stacks
- Large insurers/banks can negotiate and switch vendors when contracts renew
Scientific, Technical & Medical
Scientific & medical publishing, research platforms, and analytics (journals, databases/tools, research intelligence)
H1 2026 revenue share uses STM revenue of GBP 1,370m divided by group revenue of GBP 4,871m. Operating-profit share uses STM adjusted operating profit of GBP 519m divided by GBP 1,727m.

Content Rights Currency
Legal
Content Rights Currency
Strength
Durability
Confidence
Evidence
Ownership/control of a large portfolio of journals and authoritative reference content (distributed via owned platforms) underpins subscription and publishing revenues and strengthens bargaining position with institutions.
Content Rights Currency moat: definition, examples, and stocks
Erosion risks
- Open access mandates and funding models compress publisher economics
- Library consortia push back on pricing ('big deal' renegotiations/cancellations)
- Preprints and alternative dissemination reduce reliance on traditional journals
Leading indicators
- Renewal rates and pricing outcomes in large institutional contracts
- Share of revenue from open access publishing vs subscriptions
- Submission volumes and acceptance capacity/quality metrics
Counterarguments
- Authors and institutions can shift to open platforms or alternative publishers over time
- Publishing workflows are contestable; editorial boards can migrate journals
Data Workflow Lockin
Demand
Data Workflow Lockin
Strength
Durability
Confidence
Evidence
Research intelligence and database/tools (e.g., Scopus, SciVal, Pure) integrate into institutional research management and evaluation workflows, increasing switching costs and enabling cross-sell.
Data Workflow Lockin moat: definition, examples, and stocks
Erosion risks
- Standards-based interoperability reduces integration advantage
- Institutional preference for open bibliometrics/analytics alternatives
- Data quality challenges or bias concerns reduce trust in analytics outputs
Leading indicators
- Adoption and renewal of Scopus/SciVal/Pure contracts
- Product usage/engagement (searches, API calls, seats)
- Competitive displacement in research management systems
Counterarguments
- Institutions can use alternative bibliographic datasets and open analytics
- Multi-homing is common: customers may keep multiple databases/tools
Legal
Legal information, research, drafting, and analytics platforms (law firm, corporate legal, government, news & business)
H1 2026 revenue share uses Legal revenue of GBP 959m divided by group revenue of GBP 4,871m. Operating-profit share uses Legal adjusted operating profit of GBP 208m divided by GBP 1,727m.

Content Rights Currency
Legal
Content Rights Currency
Strength
Durability
Confidence
Evidence
Exclusive/authoritative primary and secondary legal content (case law, statutes, commentaries, citators) is the core input that differentiates answers and supports trust, especially for AI-assisted legal work where verifiable authority matters.
Content Rights Currency moat: definition, examples, and stocks
Erosion risks
- Courts/governments improve free access and APIs for primary law
- Litigation/regulation around AI outputs, privacy, or content licensing
- Content parity narrows if competitors secure similar primary/secondary rights
Leading indicators
- Content acquisition/renewal and exclusivity outcomes by jurisdiction
- Quality metrics for AI answers (hallucination rate, citation accuracy)
- Share of usage moving to non-proprietary sources
Counterarguments
- Primary law is increasingly available for free; value shifts to workflow and analytics
- Competing vendors also have deep content libraries and can integrate with AI tools
Data Workflow Lockin
Demand
Data Workflow Lockin
Strength
Durability
Confidence
Evidence
Lexis+ and Lexis+AI are positioned as core online research/drafting platforms; integration into document management and firm workflows increases switching costs and enables upsell of analytics and AI assistants.
Data Workflow Lockin moat: definition, examples, and stocks
Erosion risks
- Law firms adopt multi-platform AI copilots that abstract away the underlying research vendor
- Interoperability standards make switching easier across document management and citation tools
- New entrants bundle research + drafting at lower price points
Leading indicators
- Lexis+AI and assistant (Protege) adoption rates by customer segment
- Seat growth and module attachment (research, drafting, analytics)
- Churn/renewal outcomes among top 100 law firms
Counterarguments
- Large firms often subscribe to multiple research platforms (multi-homing)
- Large-firm bargaining power can cap price increases
Exhibitions
B2B exhibitions and events (marketplace connecting buyers and sellers; increasingly supported by digital/data products)
H1 2026 revenue share uses Exhibitions revenue of GBP 575m divided by group revenue of GBP 4,871m. Operating-profit share uses Exhibitions adjusted operating profit of GBP 226m divided by GBP 1,727m. Source: https://www.relx.com/~/media/Files/R/RELX-Group/documents/press-releases/2026/first-half-results-2026-pressrelease.pdf
Insufficient segment-specific evidence to assign a moat claim.
Print and print-related activities
Legacy print and print-related distribution for professional information content
H1 2026 revenue share uses print and print-related revenue of GBP 157m divided by group revenue of GBP 4,871m. The profit share uses the combined GBP 77m of print profit and unallocated costs divided by GBP 1,727m because RELX does not separate those items.
