Legal victory reinforces content protections
A U.S. federal judge ruled against Ross Intelligence, siding with Thomson Reuters in a copyright case. The decision establishes that its Westlaw editorial content cannot be copied under fair use, setting a precedent in AI-related copyright disputes.
Stock performance and strategic listing
Thomson Reuters shifted its U.S. listing from NYSE to Nasdaq earlier in 2025. As of September 25, its Toronto-listed shares traded at CAD 219.29, reflecting a 1.45% dip on the day but aligning with full-year guidance.
Reuters news agency leadership update
Reuters, the news division of Thomson Reuters, appointed Sally Buzbee to lead U.S. and Canada editorial operations. With experience at The Washington Post and AP, she is expected to strengthen newsroom leadership.
Broader strategy and impact
Through moves in AI education, acquisitions, and content protection, Thomson Reuters demonstrates its push to combine technology, legal expertise, and journalism while preparing professionals for a digital-first future.
