Currently, the largest car insurance company in America is State Farm. Major auto insurance companies offer financial stability and a variety of coverage plans. To find cheap car insurance rates, you'll need to compare quotes from various providers.

For auto policies, State Farm is the largest insurance company in the U.S., with the biggest market share (16.9 percent) and over $46.6 million in direct premiums written in 2022.

The fact that State Farm is a mutual insurance company means the company is privately owned by the people who purchase its insurance policies, and shares in the company are not available to investors on the public market.
