The Titans of the U.S. Insurance Industry
1. State Farm – Leading the Pack
State Farm stands at the pinnacle as the largest property, casualty, and auto insurance provider in the United States, commanding substantial revenue and an extensive agent network. In 2023, it reported revenue exceeding $104 billion, supported by around 65,000 employees and an impressive 19,000 agents across the country . According to the Insurance Information Institute, State Farm also held the top spot for homeowners insurance, capturing 18.2% of direct premiums written in 2024. For auto insurance, it commanded a dominant 18.9% share.
2. Allstate – The Trusted Name
Allstate comes in as a strong second in several key segments. It held 9.0% of homeowners insurance premiums in 2024 and 10.2% of the auto insurance market . Founded in 1931 and famously spun off from Sears in 1995, Allstate has built a well-known brand identity with its long-running slogan, “You’re in good hands” . It also places emphasis on technology—recently adopting AI-driven email communications to simplify claims interactions
3. USAA – Serving Military Families with Excellence
USAA is unique in its reciprocal inter-insurance model, exclusively serving active-duty military, veterans, and their families. Despite a more focused member base, it achieved noteworthy scale—ranking 3rd in homeowners insurance, with a 6.9% market share, and securing 5th place in auto insurance at 6.2% in 2024 . USAA’s strong financials are evident too: in 2024, it posted a $3.9 billion profit, tripling its previous level, with $48.6 billion in revenue and over 1 million new members, bringing its total to 14 million . It’s also ranked highly in customer satisfaction and has climbed to No. 93 on the 2025 Fortune 500 list .
4. Progressive – Modernizing Auto Insurance
Progressive has cemented its status as the #2 auto insurer in the U.S., right behind State Farm, holding 16.7% of the auto insurance market in 2024 . Its strength comes from innovation—Progressive’s Snapshot usage-based insurance program uses driving data to tailor premiums, an approach backed by multiple patents . In 2024, the company generated $75.4 billion in revenue and nearly $8.5 billion in net income .
5. Liberty Mutual – Global Reach & Diverse Products
Rooted in Boston and tracing its origins to 1912, Liberty Mutual is a massive global insurer offering property, casualty, life, and specialty insurance. In 2021, it generated $48.2 billion in revenue and employed over 45,000 people across 900+ locations worldwide . In the U.S., it ranked 3rd in homeowners insurance in 2024 with a 6.1% market share .
6. Berkshire Hathaway (GEICO & Others) – Powerhouse Holdings
While not an insurer in the typical sense, Berkshire Hathaway exerts profound influence through its multiple insurance subsidiaries—including GEICO and General Re . As of early 2024, it ranked among the largest insurance groups globally by revenue, consistently securing a top-five position. A.M. Best’s 2023 data confirms its presence; Berkshire Hathaway Insurance ranked #2 in property & casualty premiums written, trailing only State Farm.
7. Chubb – Global Strength & Disciplined Management
Chubb Ltd. has earned acclaim for its solid underwriting discipline, robust financial performance, and strategic global expansion . Warren Buffett’s Berkshire Hathaway has even taken a 6% stake in the company, reflecting confidence in its leadership and long-term positioning
8. Life & Annuity Giants: MetLife, Prudential, New York Life
The life insurance market is led by:
- MetLife (8.6% market share)
- Equitable Holdings (8.3%)
- Prudential Financial (5.7%)
- New York Life (5.1%)
These figures are based on 2024 direct premiums written . In broader industry rankings, New York Life tops the list, followed by Northwestern Mutual and Metropolitan Life
Why These Leaders Stand Out
- Scale & Reach: State Farm, Allstate, and Berkshire Hathaway dominate in property-casualty lines via sheer volume and infrastructure.
- Trusted Brands: Companies like Allstate and USAA rely on long-term, trustworthy branding to stand apart.
- Financial Health: USAA’s surge to profitability post-2022 and Progressive’s strong 2024 earnings underline financial robustness.
- Innovation: Progressive leads with usage-based insurance; Allstate integrates AI for better customer communication.
- Specialization: USAA’s military-focused service model, Chubb’s disciplined underwriting foundations, and MetLife’s leadership in the life insurance sector show how specialization builds strength.
Final Thoughts
The U.S. insurance landscape is anchored by giants like State Farm, Allstate, USAA, Progressive, and Liberty Mutual, each excelling in different areas—from reach and revenue to product innovation and customer satisfaction. Niche-focused leaders in life and annuity, such as MetLife and New York Life, command the market through premiums written. Holding a strategic lens, Berkshire Hathaway wields immense influence through its insurance holdings, while Chubb garners investor confidence through disciplined, global operations.
