Why Thomson Reuters (TRI) and RELX are the ultimate "Pick and Shovel" plays for the AI Regulation Era (Deep Dive 2026)

AI Summary

Author presents a long thesis on Thomson Reuters and RELX as regulatory/legal AI 'pick-and-shovel' plays, with Wolters Kluwer as a cheaper value alternative.

TRI — LONG Author says Thomson Reuters is a Strong Buy and is long TRI as a 'pick and shovel' play for the AI regulation era. Mechanism: more regulation (EU AI Act fully in 2026, US state data-privacy fights) increases demand for trusted legal data, and TRI's Westlaw/CoCounsel RAG walled garden avoids AI hallucinations and strengthens its moat. Catalysts/evidence: Q3 2025 organic growth accelerated to 7%, margins are expanding to ~40%, and it recently completed a $1B buyback with 0.6x leverage. Main stated risk: TRI's ~33x P/E may look historically expensive.

TL;DR: Long TRI and RELX. They are the utilities of the AI age. Regulation is their fuel, and AI is their engine.

RELX — LONG Author names RELX as one of the ultimate 'pick and shovel' plays for the AI regulation era and says he is long RELX. Mechanism: RELX owns 'ground truth' legal data via Lexis, which is indispensable for high-stakes law; increasing regulation and the need for RAG over trusted databases should reinforce its moat. Catalyst/horizon: EU AI Act taking full effect in 2026 and a next-five-years compounding view. No company-specific risk was stated beyond the general AI-disruption debate the author rejects.

TL;DR: Long TRI and RELX. They are the utilities of the AI age. Regulation is their fuel, and AI is their engine.

Hey everyone,

While everyone is chasing the latest semiconductor flyer or trying to guess which LLM foundation model will win, I think the real compounding machines for the next 5 years are hiding in plain sight: **Regulatory Tech (RegTech) & Legal AI.**

I’ve just finished a deep dive on the sector (TRI, RELX, ICE, WKL). Here’s the thesis on why **Thomson Reuters (TRI)** is a **Strong Buy** right now.

# 1. The "Long Complexity" Trade 🌍

The EU AI Act is fully kicking in this year (2026). US states are fighting the Feds on data privacy. The world is getting *more* regulated, not less.

* **Who wins?** The companies that sell the rulebooks.
* TRI and RELX own the "ground truth" legal data (Westlaw/Lexis). You literally cannot practice high-stakes law without them.

# 2. The AI Moat is REAL 🏰

People think AI kills these companies ("Why pay for Westlaw when ChatGPT is free?").

* **Reality:** ChatGPT hallucinates. In law, a hallucination gets you disbarred.
* **The Solution:** RAG (Retrieval-Augmented Generation). TRI’s **CoCounsel** AI answers questions using *only* trusted Westlaw cases. It’s a "Walled Garden."
* **Result:** This actually *strengthens* their moat. The open web is flooded with AI slop; their database is the only clean water left.

# 3. The Numbers Don't Lie 📈

* **Organic Growth:** TRI used to grow at 3-4%. In Q3 2025, they hit **7% organic growth**. That’s a structural re-rating.
* **Margins:** Expanding to \~40%.
* **Buybacks:** They just finished a $1B buyback and have remarkably low leverage (0.6x).

# 4. Valuation 💰

TRI trades at \~33x P/E. Expensive? Maybe historically. But for a company growing 7%+ organic with 40% margins and a monopoly-like moat in an AI world? I think it's fair. **Wolters Kluwer (WKL)** is the value pick (trading at \~23x) if you want a cheaper entry point, but TRI has the momentum.

**TL;DR:** Long TRI and RELX. They are the utilities of the AI age. Regulation is their fuel, and AI is their engine.

*(Disclaimer: This is not financial advice. Do your own due diligence. I am long TRI and RELX.)*
