Thomson Reuters Shares Rally After CoCounsel AI Tool Draws 1 Million Users
Thomson Reuters' AI legal assistant CoCounsel now serves one million professionals globally, reducing legal research time by up to 70%, signaling broader AI adoption in legal services.
- Thomson Reuters said Tuesday that CoCounsel has one million users in more than 100 countries, and shares rose more than 10% on the Toronto Stock Exchange.
- Thomson Reuters said the milestone reflects CoCounsel’s shift from experimentation to production after a year working with Anthropic and integrating with Westlaw, Practical Law, and Microsoft 365, while CEO Steve Hasker emphasized trust and data protection.
- Thomson Reuters said CoCounsel's first version cut manual processes by 60 to 70 percent, and its model outperformed GPT‑5 and Claude Opus 4.5 in benchmarking, with users in 107 countries and territories.
- With a $175 target, Adam Shine warned the early gain may not hold, as Thomson Reuters hit one million users, marking a shift from experimentation to production.
- Positioning CoCounsel against plug‑in tools, Thomson Reuters said its AI software is already taking hold at law firms and tax practices, with Wong predicting a turning point this year.
