Latest Data on Insurer’s Exposures & Market Share
Published every other month, Agency Checklists’ CAR Updates review the latest data on the current state of the Private Passenger Automobile Insurance marketplace. For our second look of the year, this update reviews the market share data as of February 2025, the latest date for which complete data is available.
The top 10 insurers in this line of insurance continue to dominate the marketplace in Massachusetts with a total of 715,153 exposures, representing an 84.46% share of the market. In looking at the data, however, Agency Checklists thought it might be instructive to take a look at the changes and movements in insurer’s exposures and market share at
Five thoughts on the market share data when comparing February 2025 to February 2024
Commerce Shrinks Slightly but Retains Dominance
Commerce Insurance remains the market leader in February 2025 with 154,622 exposures and 18.26% market share. This number, however, reflects a decline from the 159,615 exposures and 19.02% it had at this same time in the prior year.
This change represents a loss of 4,993 exposures, or a 3.1% year-over-year drop, indicating a modest erosion while still holding the top spot.
Progressive Surges, Passes Safety
Progressive appears to have grown sharply jumping when comparing its numbers from February 2024 to February 2025. It increased from 65,014 exposures (7.75%) in February 2024 to 91,605 exposures (10.82%) in 2025.
This 40.9% year-over-year increase (26,591 exposures) vaulted Progressive into 3rd place, overtaking Safety, which grew more modestly from 80,947 to 82,551 exposures.
GEICO and Arbella Both Decline
GEICO lost 13,186 exposures, falling from 113,381 (13.51%) to 100,195 (11.83%) when comparing 2024 and 2025 numbers for the month of February. Arbella similarly declined, shedding 2,827 exposures, dropping from 62,046 (7.40%) to 59,219 (6.99%), though it remained in 6th place.
Middle-Tier Regional Carriers Gain Share
Standard Fire (Travelers) gained 6,755 exposures, growing from 5.46% to 6.21%, leapfrogging Liberty Mutual, which dropped from 53,475 to 48,003 exposures. Norfolk & Dedham and Quincy Mutual both posted small gains, while Hanover shrank slightly (-2,200 exposures, now 2.21%).
Smaller Market Entrants Show Volatility
Incline more than doubled its exposure count, rising from 1,057 to 2,099 (+98.5%), and Cincinnati increased by 29.9%, while Pure and Electric both posted sharp declines.
Electric Insurance is in runoff, and its plunge from 1,775 to 42 exposures confirms its market exit is progressing.
