Top 20 largest US insurance companies 2021

Insurance companies are key actors of the American economy, hedging risks and covering the costs of accidents. Present throughout the country and abroad, US insurance companies are involved in life and health insurance, property and casualty insurance, business and commercial insurance, and reinsurance.


The top American insurance companies are important parts of the financial sector and they play a major role in the economy through the management of risks. However, they are engaged in fierce competition against each other for market share in the US and abroad, and face competition from foreign insurers looking to expand their foothold in their domestic market. Other financial companies, such as banks and financial services companies, also challenge them in their insurance and risk management activities in financial markets.

Though they face stiff competition to provide insurance and risk mitigation products and services to individuals, businesses, and institutions, the most important threat for insurers comes from the disruption of their traditional business by insurance tech startups. These new “InsurTech” companies create new ways for people and companies to hedge, manage and anticipate risks and exposure to various hazards, which can impede the activities of traditional insurance companies. And some of them, among the largest US startups, have already grown to become “unicorns”: startups with a valuation above 1 billion dollars.

Nevertheless, insurance companies are still a pillar of the US economy and they will remain in this position for the foreseeable future. The US is such a great business arena for insurers to prosper that they can use their national foothold to expand abroad and conquer new markets. Whether they provide life and health insurance, property and casualty insurance, insurance brokering services, or reinsurance, insurance companies are in the US to stay, and potentially, also to conquer the rest of the world.
