State Farm is the largest insurer in the U.S., with 10.39% of the market, according to the National Association of Insurance Commissioners, which collects insurance data from all 50 states and Washington, D.C. The rankings cover every type of insurance outside of life and health, including car, home and business policies. Progressive ranks second at 7.59%, followed by GEICO’s parent company Berkshire Hathaway at 5.81%. Together, the top five companies hold 33.04% of the market, and every other insurer splits the remaining 66.96%.

Every insurer prices policies with its own formula, so a company’s size doesn’t set what you’ll pay. Richard Attanasio, senior director at AM Best, says the largest insurers lean heavily on branding and marketing to stand out, which is why their names are so familiar. He also expects insurers to rely more on driver data to set car insurance rates, so two companies can quote you very different prices for the same coverage.

Get quotes from a few of these insurers and one or two smaller ones, using the same coverage and the same deductible, the amount you pay before insurance covers the rest. Comparing identical policies shows you which company charges the least for your situation.

How to read insurance company market share rankings

The rankings show how much each insurer charged customers for policies in 2025. They also show the share of the industry’s total premiums that money represents. The figures come from each company’s “direct” premiums, which is what it takes in from its own customers before passing any risk on to other insurers.

Each column in the table measures a different part of a company’s business:

The insurance company is the parent company. Many large insurers own several brands, and the table combines them, so Berkshire Hathaway’s total includes GEICO.
Direct premiums written is what customers were charged for policies sold or renewed. State Farm wrote $115.3 billion, the most of any insurer.
Direct premiums earned is the portion of premiums that paid for coverage already provided during the year. A 12-month policy sold in July has earned half its premium by Dec. 31, which is why State Farm earned $112.9 billion against $115.3 billion written. Liberty Mutual and Nationwide earned more than they wrote, since part of their 2025 earnings came from policies sold in 2024.
Market share is a company’s portion of all premiums written across the industry. State Farm’s $115.3 billion out of $1.11 trillion industry-wide gives it 10.39%.

How national and regional insurance companies differ

An insurer’s size reflects how many customers it has, not whether its price or service fits you. National insurers sell policies in most or all states, while regional insurers sell in one state or a few neighboring ones, and each type tends to have different strengths.

Pros and cons of national insurance companies

A national insurer’s scale shapes what it offers and how it handles your account:

More coverage types in one place. Many sell car, home and life insurance, so you can bundle your policies with one company.
Support at any hour. Many offer 24/7 help by phone or app.
Fast online tools. Larger budgets tend to pay for polished apps and quick online quotes.
Less personal service. You may speak with a different representative each time you call.
Less flexibility. Decisions usually follow a company-wide process, which leaves less room for exceptions.

Pros and cons of regional insurance companies

A regional insurer’s smaller footprint tends to change the service you get:

Coverage built around local conditions. Policies can reflect the weather and driving laws where you live.
A local agent. You’re more likely to work with an agent in your community, often the same one each time.
Case-by-case decisions. Smaller companies often have more room to work with your specific situation.
Fewer coverage options and shorter hours. Some don’t sell every type of insurance or offer round-the-clock support.
Simpler online tools. Apps and websites may have fewer features.

Some companies in the rankings, like Erie Insurance, sell in a limited number of states. Your state insurance department’s website lists every company licensed where you live, so you can find regional insurers to add to your quotes. Including one or two of them shows whether a local company beats the national names on price.

How to choose an insurance company

An insurer’s quote shows what you’ll pay, but not how the company handles a claim or whether it has the money to pay one. Checking every company you’re considering against the same points shows which one gives you the best overall value.

Price. Each insurer weighs risk with its own formula, so rates for identical coverage vary from one company to the next. Getting at least three quotes with the same coverage and deductible shows you the range of prices available to you.
What you’re insuring. Insurers price a car based on factors like its repair costs, theft rates and safety ratings. They price a home based on its age, construction and location. A company that charges more for your car may charge less for your home, so get quotes for each policy you need.
Financial strength ratings. AM Best and S&P Global grade insurers on their ability to pay claims. A strong rating means the company has the money to cover your claim, even in a year with heavy losses.
Claims satisfaction. J.D. Power surveys customers on how their insurers handled recent claims. These scores show how quickly and fairly a company pays out.
Discounts. Many insurers lower your rate for bundling policies, going claims-free or having safety features like anti-theft devices and smoke alarms. Discounts aren’t always applied automatically, so asking what you qualify for can bring your quote down.

Our agents make it hassle-free to get the right quote.
