Nessel Accuses Blue Cross Blue Shield of Running Illegal Monopoly
The complaint says BCBSM controlled about 65% of Michigan’s health insurance market and used its power to raise costs and limit competition.
- On Thursday, Oct. 8, 2026, Michigan Attorney General Dana Nessel filed a federal antitrust lawsuit against Blue Cross Blue Shield of Michigan, alleging the insurer operates an "illegal monopoly" harming state residents and employees.
- Nessel alleges Blue Cross conspired with other Blue Cross Blue Shield entities to "allocate customers and territories," restricting competition for large employers and state employee insurance plans across the state.
- Controlling approximately 65% of all health insurance products and 79% of the PPO market, Blue Cross has allegedly abused its dominance to lower provider payments while filing premium increases of about 24% for individual members this year.
- Blue Cross issued a statement claiming it was "blindsided" by the lawsuit and disagreed with characterizations of an uncompetitive market, while Nessel seeks damages and a permanent injunction against the company's conduct.
- Federal cases often take months or years to resolve, and Nessel's successors—including candidates Doug Lloyd and Eli Savit—will determine how the state proceeds with this antitrust enforcement effort.
