State attorneys general (State AGs) are becoming increasingly active in the realm of antitrust enforcement, focusing on mergers, monopolization, and ESG-related cases. In recent years, state AGs have taken assertive roles in challenging major mergers, such as JetBlue’s attempted acquisition of Spirit Airlines and Kroger’s attempted acquisition of Albertsons. These actions highlight a trend of state AGs bringing their own cases in state courts, sometimes parallel to federal enforcement efforts. State AGs have also been at the forefront of monopolization cases, particularly against big tech companies, and have challenged algorithmic pricing and data sharing arrangements. Additionally, ESG-related antitrust actions have emerged, with red state AGs investigating financial institutions supporting environmentally conscious investing. In the latest episode of MoForecast, Morrison Foerster partners Carrie H. Cohen, global co-chair of the Investigations + White Collar Defense Group and State + Local Government Enforcement team, and Megan Gerking, partner in the firm’s global Antitrust Law practice, discuss the current state of antitrust enforcement by state AGs and what to expect in 2025. They explore the potential for state AGs to continue active participation in merger and conduct investigations, possibly filling perceived gaps in federal enforcement under the new Trump administration. Listen to the episode to gain a deeper understanding of the future of state AG enforcement in the antitrust arena.
