The firm is pleased to distribute the Wilson Sonsini Global Cartel Law Quarterly Q4 2025/Q1 2026, which provides a summary of key cartel enforcement trends across the U.S., Europe, and beyond. A “cartel” under competition law is typically reserved for agreements between competitors to restrict competition, such as price-fixing, bid-rigging, and market allocations.

This quarterly report provides updates on how competition law applies to company collaborations generally. In doing so, the authors hope this quarterly helps companies structure legitimate collaborations and avoid “cartel” behavior. In this edition, the authors examine the key developments in Q4 2025/Q1 2026, and lay out their expectations for what the remainder of 2026 is likely to look like in the area of cartel enforcement.
