Each Spring, the National Association of Insurance Commissioners (NAIC) releases its analysis of the top property and casualty insurers of the year. With nearly 98% of insurers reporting, the NAIC determined the industry recorded around $1.06 trillion in direct written premium in 2024, with the top ten P&C insurers accounting for about 51% of the total market share.
The largest line of business remains personal passenger auto, with an estimated $344.11 billion in written premium, which makes up about 35% of the overall market.
