Car Insurance Companies: Who's Biggest and Who's Cheapest (2026)

Full transcript

I. A concentrated market

In NAIC data for twenty twenty-three, State Farm wrote fifty-seven point nine seven billion dollars in direct premiums. The ten largest writers account for roughly three quarters of all private passenger auto premiums, so these are the names behind most quotes, ads and agents.

II. The top five

Progressive is second at fifteen point two percent. Berkshire Hathaway, which reports GEICO's premiums, is third at twelve point three, and Allstate is fourth at ten point four. USAA is fifth at six point two percent, and it only serves military members, veterans and their families. The full top ten table is in the free guide.

III. Six to ten

Below the top five, the shares drop quickly. Liberty Mutual and Farmers each write four point two percent. American Family and Travelers write two point one percent each, and Nationwide, in tenth place, writes one point seven.

IV. Size is not price

Size is not price. The most recent NAIC countrywide average expenditure is one thousand two hundred eighty-one dollars and ninety-two cents per insured vehicle, from twenty twenty-three, and premiums have risen substantially since. In the site's twenty-metro quote-spread study, the top ten carriers quoted one standardized driver profile in Miami from roughly two thousand four hundred to seven thousand eight hundred dollars a year, depending on the company.

V. How they sell

Companies also sell differently. State Farm, Allstate and Farmers sell mainly through local agents, while Progressive and GEICO sell mainly direct and online. Regional insurers such as Erie and Auto-Owners often compete on price and claims satisfaction inside their own footprints.

VI. Cheapest doesn't last

And the cheapest company rarely stays the cheapest, because rates are re-filed constantly. The full guide is free at Dreamy Leads Research. What state do you drive in, and what do you pay a year for car insurance? Tell us in the comments.
