The Data Defender: How RELX Turned the Generative AI Threat into a Growth Engine

LONDON – October 22, 2026 – Just a few years ago, the prevailing narrative in Silicon Valley was that generative artificial intelligence would disintermediate traditional data providers. The assumption was simple: if a large language model could instantly synthesize the world's information, the legacy gatekeepers of professional analytics would quickly find themselves obsolete.

Yet, the third-quarter 2026 trading update from RELX PLC tells a radically different story. Instead of being disrupted, the £51 billion British analytics and information giant has weaponized AI to accelerate its own expansion.

Reporting a 7% underlying revenue growth year-to-date across the group, RELX reaffirmed its full-year outlook for strong growth in underlying revenue, adjusted operating profit, and constant-currency adjusted earnings per share. But the real story lies beneath the headline figures, in the intricate mechanics of how the company is embedding "agentic" AI capabilities into the daily workflows of lawyers, scientists, and risk managers.

By marrying proprietary, verifiable data with advanced machine learning, RELX has successfully transformed an existential threat into a high-margin growth engine, proving that in the age of AI, the model is only as valuable as the data it is trained on.

The Legal Tech Arms Race: Proprietary Data Meets Agentic AI

The standout performer in RELX’s portfolio is its Legal division, which posted a remarkable 10% underlying revenue expansion for the first nine months of the year. This double-digit growth in a traditionally conservative sector underscores a massive behavioral shift among legal professionals.

Industry analysts note that roughly 79% of legal professionals now use AI in some capacity, up from just 19% in 2023. This represents one of the steepest technology adoption curves ever recorded in the corporate world. RELX’s LexisNexis unit has capitalized on this urgency through its Lexis+ AI platform, which has evolved beyond simple search and summarization into multi-practice matter tracking and customizable workflow automation.

The core challenge for legal AI has always been the hallucination problem—the tendency of large language models to invent case law. Recent independent audits of purpose-built legal AI tools revealed baseline error rates hovering between 17% and 33%. However, RELX has aggressively tackled this vulnerability by grounding its AI outputs in its proprietary Shepard’s citation validation system. Recent evaluations from October 2026 demonstrate that this closed-loop approach pushes audit accuracy to an impressive 99.4%.

This high-fidelity output is critical as the competitive landscape intensifies. Thomson Reuters continues to push its Westlaw Advantage and CoCounsel platforms, while a flood of venture capital—highlighted by recent $1 billion valuations for legal AI startups—has birthed a new ecosystem of "AI-native" law firms focused on fixed-fee, automated contract review. By providing the trusted "picks and shovels" for this gold rush, RELX ensures it profits regardless of which specific law firm or startup wins the market share battle.

Scientific and Risk Workflows: The LeapSpace Effect

The transition from traditional content publishing to mission-critical workflow software is equally evident in RELX’s Scientific, Technical & Medical (STM) division, which recorded a 6% underlying revenue growth.

For years, the academic publishing industry has been navigating the complex transition toward open-access models, a shift that threatened traditional subscription revenues. RELX’s response has been to pivot the value proposition from access to analysis. The recent rollout of LeapSpace, a research-grade AI workspace, exemplifies this strategy.

LeapSpace doesn't just provide access to academic papers; it actively assists researchers in synthesizing data, identifying literature gaps, and managing submission workflows. This evolution toward higher-growth, higher-value analytics effectively insulates the STM division from the commoditization of raw academic publishing.

Meanwhile, the company’s Risk division—which accounts for roughly 40% of the group's total profit—delivered an 8% underlying revenue growth. This unit operates quietly but forms the bedrock of RELX's exceptional 66% gross margins. The growth here is largely driven by deeply embedded Financial Crime Compliance and digital Fraud & Identity solutions. As financial fraud becomes increasingly sophisticated via AI-generated deepfakes and synthetic identities, RELX’s proprietary contributory datasets become indispensable for global insurance and banking institutions trying to manage systemic risk.

Geopolitical Friction in the Physical World

While RELX’s digital divisions are compounding at impressive rates, its physical operations offer a sobering reminder of global macroeconomic and geopolitical realities. The Exhibitions division (RX Global) lagged behind the rest of the company, posting a 4% underlying revenue growth.

This deceleration is directly attributable to ongoing disruptions in the Middle East, which have forced the delay or cancellation of key regional events. Despite this localized friction, the broader event portfolio maintains a strong growth profile. The company noted that, excluding the Middle East impact, it still expects strong underlying revenue growth and an improvement in adjusted operating margins over the prior year for the Exhibitions unit.

This physical-world drag highlights the strategic brilliance of RELX’s multi-decade digital transformation. Twenty years ago, a regional geopolitical crisis severely impacting the physical events business might have derailed the company's entire quarterly earnings. Today, it is merely a minor headwind, easily offset by the relentless, high-margin growth of its software and analytics divisions.

The New Economics of Professional Intelligence

As we look toward the remainder of 2026 and beyond, the financial implications of RELX's strategy are profound. The professional services industry is undergoing a structural transformation in how it bills and operates. Technology analysts forecast that specialized legal AI platforms will double corporate legal technology budgets by 2028, with a significant shift toward consumption-based pricing models.

RELX is perfectly positioned to capture this expanding wallet share. By ensuring that underlying adjusted operating profit growth exceeds underlying revenue growth across its Risk, STM, and Legal divisions, the company is demonstrating immense operational leverage. They are successfully managing the high computational costs associated with generative AI while simultaneously extracting premium pricing for their verified, trusted content.

The 2026 trading update confirms a vital lesson for the modern information economy: algorithms are rapidly becoming commoditized, but verified, proprietary data is not. By acting as the trusted arbiter of professional intelligence, RELX has not only survived the generative AI revolution—it has built an impenetrable moat right through the middle of it.
