The Biggest Ten Auto Insurance Companies in the USA

Question: There are many ways of classifying auto insurance companies, I guess. However, looking at them based on market share (or size, probably the same thing) would be just stating the facts rather than offering opinion. Probably the debate would go on forever if we were to choose the top auto insurer based on customer satisfaction since everyone would have a different opinion.

Answer: I agree, size is an indisputable way of ranking car insurance companies. How many auto policies they sold last year is a matter of statistics (not opinion). Here is an info graphic to show the top ten largest car insurance companies in the USA. Figures are little old but gives you a very good idea where they stand.
