Progressive Insurance Group Maintains Market Dominance in Commercial Auto No-Fault Insurance

Progressive Insurance Group continued to dominate the U.S. commercial auto no-fault coverage market in 2025, maintaining its lead despite a minor dip in direct premiums written (DPW), according to Best's Rankings.

In 2025, Progressive Insurance Group reported a DPW of $203.6 million, marking a slight decrease of 0.1% from the previous year and resulting in a market share decline from 16.6% to 16.3%. While these figures demonstrate resilience in a competitive market, the company's commercial auto no-fault policies account for just 0.2% of its total premiums. Meanwhile, American Transit Insurance Co. experienced a significant 9.6% increase in DPW, reaching $126.2 million and surpassing Liberty Mutual Insurance Cos., which faced a substantial 34.4% drop to $118.1 million.

Noteworthy Position Changes in the Industry

Several insurance groups demonstrated remarkable performance shifts that altered their standing in the market. MS&AD US Insurance Group made a notable leap from 60th to 4th place, fueled by a DPW spike to $54.1 million, boosting its market share from 0.2% to an impressive 4.3%. Similarly, Berkshire Hathaway Insurance Group advanced from 8th to 5th position, with a significant DPW increase of 53.5%, totaling $51.8 million.

Trends and Implications for Insurers

The broader commercial auto no-fault sector experienced a modest 1.4% increase in DPW, reaching $1.25 billion in 2025. This growth reflects the combined efforts of the top 25 companies, whose collective DPW also rose by 1.4% to hit $1.0 billion. This consistency indicates a steady demand and competitive dynamics that require insurers to continuously adapt their underwriting strategies and manage risk effectively.
