The total worth of a company’s stock, also known as market capitalization, is computed by multiplying the number of outstanding shares by the current share price. It’s a quick approach for investors to figure out how much a firm is worth. Companies having significant market capitalizations are generally considered to be safe investments. They are likely to grow steadily and pose the least degree of risk. Mid-cap corporations are well-established but have a lot of room for expansion. Finally, small-cap companies are frequently startup businesses with significant growth potential. Investing in small companies carries the most risk because they are more susceptible to economic downturns than larger and mid-cap corporations.

Largest Insurance Companies by Sales and Product Line

It is useful to differentiate between the type of insurance, or line, that is being considered when considering the largest insurance companies. Using sales data is helpful as some of the largest insurance companies in the United States are not publicly traded and therefore their market value is not easily ascertained.

Property & Casualty

Property and casualty insurers write policies covering property such as real estate, dwellings, cars, and other vehicles. They also write policies dealing with liabilities that may be incurred by accident or negligence related to those properties to defray the cost of lawsuits or medical damages resulting from such incidents.

The top U.S. property and casualty companies in 2020 by net premiums written (the amount of money that non-life policies can expect to receive over the life of the contract, less commissions and costs) are….

Berkshire Hathaway (BRK.A) $46.4 billion 
Progressive Insurance Group (PGR)$41.7 billion

Travelers Group (TRV) $28.8 billion 
USAA Group$24.6 billion
Chubb (CB)$24.2 billion
Farmers Insurance Group$20.1 billion 
Nationwide$18.5 billion

Life Insurance Companies

Life Insurance companies promise to pay out a lump sum benefit upon the death of the insured. Although actuarial science has created mortality tables to accurately estimate the future liability of policies to be paid, having financial strength ensures that these companies can meet all of their obligations while still earning a profit.

Life Insurance companies in the U.S. can be ranked by direct premium written (the number of new policies written directly and not re-insured). For 2020…….

Health Insurance Companies

Health insurance companies provide policies to cover all or part of the policyholder’s health and medical costs. Policies may be purchased individually or through an employer. Technically, the United States government is the largest health insurance provider in America through the Medicare program, Social Security, and Medicaid administered by individual states.
