Among US-listed property and casualty insurers, Progressive earned the most net premiums in 2025: $81.7 billion, according to the financial data it files with the SEC. Allstate and Chubb follow. The 60 listed insurers in the SEC's data earned $450 billion between them, and the first three earned 44% of it.
This is a ranking of publicly traded insurers, not of the whole market. Mutual and reciprocal insurers, several of them among the biggest in the country, do not file financial statements with the SEC, and Berkshire Hathaway reports its insurance premiums only by business segment. They are not in it.

How concentrated the listed market is
- The first three listed insurers earned 44% of the premiums the 60 listed insurers reported to the SEC, and the first ten 76%.
- The thirtieth earned $1.3 billion.
- Loews Corp. is left out because it consolidates a listed insurer whose premiums are already in the table; the two report the same figure to the SEC.
What this means for technology buyers
An insurer writing premiums at this scale runs policy, rating and claims systems that have to change with every filing season. These guides compare the options:
- Document management for insurance claims: the records behind every loss, from first notice to payment.
- Claims fraud detection for auto insurers: the biggest line for most personal insurers.
- Regulatory compliance software for insurers: rate filings, statutory reporting and market conduct.

How this list was built
The universe is every company EDGAR files under SIC codes 6331 and 6351 (fire, marine and casualty insurance, and surety) whose shares trade on a US exchange, with the net premiums earned it reported in the SEC's XBRL financial data for 2025. The SEC aligns each company's fiscal year to the nearest calendar year.
Limits
- Listed companies only. Mutual and reciprocal insurers file no financial statements with the SEC, and some of the largest property and casualty writers are organized that way.
- Berkshire Hathaway is missing. Its insurance businesses are large, but it reports their premiums only by segment, so there is no company-level figure to rank.
- Worldwide, not US. Premiums cover every country an insurer writes in, including reinsurance assumed.
- Surety included. The surety code brings in mortgage, financial guaranty and surety insurers alongside property and casualty writers.
- As tagged. Figures are what each company tagged in its filing; a company that used a different tag for its premiums is not in the table.
