List of car insurance companies

Fact-checked with HomeInsurance.com

When shopping for a car insurance company, many drivers look for the largest carriers on the market. But with nearly 2,500 property and casualty insurance companies, finding the best of the biggest providers can be challenging. 

If you’re looking for a reputable, widely-available car insurance company, keep reading to learn about our top picks of the biggest auto insurance companies (based on market share). We’ll also review the pros and cons of the top 10 biggest providers, and explain how you can choose the right auto insurance carrier for your needs and budget.

What are the largest auto insurance companies?

To find the biggest car insurance companies, we looked at the National Association of Insurance Commissioners’ (NAIC) Top 25 U.S. Private Passenger Auto Insurers report. These car insurance companies have the largest market share in terms of the number of direct premiums written and respective coverage area

Major insurance companies typically offer cheaper rates, better coverage options and more discounts than local and regional carriers because policyholder risk is less dependent on regionally-specific risk factors. These companies are also more likely to offer online quotes, online claim filing and a mobile app. Choosing a provider with a wide coverage area makes it easy to keep your policy throughout your lifetime, even if you move states. 

Here are the 10 largest auto insurance companies based on market share and the number of direct premiums written (represented here in total value) in 2019:

  • State Farm: $40,878,781,217
  • Geico: $34,892,003,836
  • Progressive: $31,025,771,905
  • Allstate: $23,626,742,688
  • USAA: $15,231,169,153
  • Liberty Mutual: $11,701,810,697

How to choose the right car insurance carrier

Choosing the right car insurance company takes careful thought and consideration. There are a few key aspects to keep in mind before you select a provider. Here are some ways to choose the best car insurance company for you:

  • Read reviews: first, look at reviews to see what real customers think about the company. J.D. Power and NAIC are good, unbiased resources.
  • Get a recommendation: ask your friends and family about their insurance providers to get a sense of customer service and overall satisfaction. 
  • Look at financial strength: look at the company’s financial strength ratings from AM Best. A score of A- for above indicates excellent financials, which means the company has enough money to repay policyholders even in the event of a widespread loss. 
  • Pay attention to discounts: keep an eye out for insurance companies that offer several discounts you can take advantage of, as this will help offset premiums. 
  • Consider add-on coverages: depending on your situation, you may want to purchase add-on coverage, like accident forgiveness, gap insurance or rideshare insurance. Not all optional coverages are offered by all providers. 
  • Compare rates: Once you’ve settled on a few contenders, get sample quotes from each company to compare the rates side-by-side. 


  • Large car insurance companies write billions of dollars in direct premiums each year.
  • Big companies generally have the ability to offer cheaper rates, better discounts and more coverage options than local providers.
  • When selecting from the top providers by market share, compare quotes to find the best fit for your circumstances. 

The benefits of choosing a large car insurance company include having a provider that you can keep no matter where you live, plus the perks of competitive rates and strong financial backing to your policy. But before you choose a provider, shop around and consider the things that are most important to you. The biggest car insurance companies are not always guaranteed to have the best prices in your state, or the highest level of customer service. Different insurance companies have their strengths and weaknesses, so use this guide as a starting point for your own research.
