State market share reports
Who actually writes the business
The insurers you see advertised are not necessarily the ones writing your state's policies. State regulators publish market share reports listing every licensed company's premium volume by line of insurance. These pages show the top writers of auto and homeowners coverage per state, and mark the carriers you cannot buy from directly, because knowing who is big in your state changes who you ask for quotes.
Market share reports are live today for California and Texas. More states arrive one regulator at a time, as each publishes its own machine-readable file. National, county-level nonrenewal data is on the nonrenewals page.
The headline numbers
- The largest single-state auto share in the data: Progressive County Mutual Insurance Company, 21.0% of Texas auto premium in 2024 ($7,421,580,650 in direct premiums written).
- The largest single-state homeowners share: State Farm Gen Ins Co, 20.1% of California homeowners premium in 2025 ($3,300,825,564 in direct premiums written).
- Shares are of one state's premium for one line, from that state's own report, so no figure here compares companies across state lines.
Data: California Department of Insurance and Texas Department of Insurance market share reports, 2024 and 2025.

Why only some states: most state-level market share tables are published only in a national association's paid or restricted reports. States that publish their own machine-readable files (California, Texas, Florida) are shown here with attribution.
