Five thoughts on the latest market share data

The following are five insights courtesy of Chat GPT on the movements happening in the marketplace based on a comparison of the market in April 2024 versus the state of the marketplace as of April 2025.

2025: 11.65% market share (198,752 exposures)
2024: 8.56% market share (144,033 exposures)
Change: ▲ +3.09 points | ▲ +54,719 exposures
Takeaway: Progressive posted the most significant growth of any major carrier, rising from fourth to third place. Its upward momentum closed the gap with GEICO and suggests aggressive growth in the Massachusetts auto space.

Commerce:

- Change: ▼ –0.78 points | ▼ –8,719 exposures
Takeaway: The state’s top two carriers saw measurable declines. While Commerce retained its number one position, GEICO’s notable loss in share narrowed the gap between itself and Progressive.

2024: 3,121 exposures (0.19%)
Change: ▼ –3,045 exposures
