Last week, the National Association of Insurance Commissioners (NAIC) released its annual market share data reports, illuminating the health and activity of property and casualty (P&C) insurance. The "Property/Casualty Market Share report" offers cumulative market share data and spotlights the top insurance writers in various personal and commercial product verticals, as well as the leading insurers overall based on written premiums across all lines of business last year. Check out the slideshow above for the rankings of the top P&C insurance groups and companies for all lines in 2019. |

Key highlights

The report reflects data filed by insurers as of March 6, 2020, for business conducted in U.S. states and territories and Canada, with an estimated 97.64% of P&C filings received at that time. NAIC's data, to date, reveals the top 10 P&C companies collectively account for 47.44% of the market share. Additionally, the total direct written premiums for the P&C industry for all lines exceeded $707 billion in 2019 — up from $681 billion in 2018. The report will continue to be updated throughout March. The full "2019 Market Share Reports for Property/Casualty Groups and Companies" will be available this summer and will contain more in-depth information. Related: |
