State Farm is still the largest car insurance company in the U.S., followed by Geico and Progressive. The top three private auto insurers – State Farm, Geico and Progressive – combined to account for 45% of the overall market share in 2022, according to S&P Global Market Intelligence, which tracks these numbers annually.
S&P reported that the U.S. private auto insurance industry had its worst underwriting results in over two decades in 2022. According to the report, “a combination of inflationary pressures, adverse prior-year development and Hurricane Ian contributed to the 111.8% figure. While rising premium rates have yet to catch up to the losses insurers are sustaining, Market Intelligence projected in October 2022 that the business line should be close to breakeven in 2024 and see a sub-100% combined ratio in 2025 and 2026. A combined ratio below 100% generally indicates underwriting profitability.”
- The benefits of buying coverage from a large insurance company generally include lower rates and more robust coverage options.
- The disadvantage of buying coverage from a large company is that you may get less satisfactory customer service.
- State Farm, Progressive, Geico, Allstate and USAA top the list of the 10 largest auto insurance companies for direct premiums written.

Benefits of large vs. small insurance companies
Although most car insurance policies are sold by the largest car insurance companies, there are benefits to working with a smaller insurer. See the benefits of each below.
Pros of larger auto insurance companies
In general, car insurance policies that major insurance companies underwrite tend to be less expensive. Because large insurers write millions of policies each year, they can afford to price their policies more competitively.
“The best benefit of larger insurance companies is that they often have a larger pool of money to offset risk, which means they should be able to maintain more stable premiums,” says Shane Page, president of Piedmont Insurance Associates in North Carolina. “If a small company sustains catastrophic losses from a storm in a given state, it will impact their future rates much more drastically than the large companies who sustain the same losses.”
Additionally, the biggest insurance companies in the U.S. often have more coverage options. A large provider will likely have those policies if you want to customize your policy with endorsements or need specialty coverage like rideshare insurance.
Pros of smaller car insurance companies
On the other hand, smaller local insurance providers usually have better customer service than large providers.
“Small companies are often much more personal and locally engaged, as you would expect,” Page says. “Plus, there is usually more latitude for underwriting decisions, and being a loyal customer can pay off.”
So, choose a local insurance company if you prefer to work with an agent in person and value a customized experience. But if your main concern is price, or if you need a specific type of coverage, a large provider may be more suitable.

Frequently asked questions: Largest auto insurance companies
What are casualty insurance companies or casualty insurance groups?
Insurance companies are often called “property and casualty insurance” companies or groups. This term describes, in general, what types of insurance are involved and what they cover. The property component relates to things you own that are covered by insurance, such as your car.
Casualty insurance covers you if you damage other people’s property or are at fault for their injuries and they file a claim against you.
What does “insurance premium” mean?
“Insurance premium” is what the insurance industry refers to for what you pay to a company for a policy. However, people generally use the words “rate” interchangeably with “premium,” though they technically mean two different things.
A premium is what you pay to a company for coverage. Insurance rates are the numbers insurance companies file with regulators to determine policy pricing. When an insurance company files rates with state commissioners, they are reviewed. After they are approved by regulators, the company uses the rates to determine how much drivers pay for coverage.
What does “direct premiums written” mean?
“Direct premiums written” represents the premiums, or what policyholders will pay, for all policies that an insurance company and its affiliate companies have written or issued during the year. When researching which casualty insurance companies have the most market share, you will often see it measured by the number of direct premiums written during a specific time.
What does “net premiums written” mean?
You may see this term when researching which companies are the largest. “Net premiums written” is the total amount of premiums a company has written, minus costs for commissions and policies it has subcontracted to other companies.
