For the first time since World War II, a new leader has emerged in the U.S. private auto insurance market on a trailing 12-month basis, according to estimates from S&P Global Market Intelligence.
Progressive Takes the Lead
Based on the aggregation of available statutory results from 43 entities, Progressive generated $18.11 billion in private auto direct premiums written during the first quarter. In comparison, the eight State Farm entities writing private auto policies collected $17.07 billion over the same period.
The shift marks a significant milestone in the industry. Progressive had already surpassed Berkshire Hathaway’s Geico Corp. as the nation’s second-largest private auto insurer in 2022. Now, with this latest data, Progressive has overtaken State Farm to claim the top spot on a full 12-month basis.
Data and Timing
S&P Global Market Intelligence plans to post first-quarter statutory results on or about May 20, with trailing 12-month data scheduled for posting the following day. These figures confirm Progressive’s ascendancy based on premiums written from April 2024 through March 2025.
The industry has not seen a change in the 12-month market share leader since the post-World War II era, underscoring the scale of this competitive shift. Progressive’s growth trajectory reflects broader trends in pricing, underwriting, and customer acquisition strategies.
Officials at S&P Global Market Intelligence noted that the estimates are derived from statutory filings and may be subject to minor adjustments once complete data is released. However, the preliminary numbers clearly indicate a new market leader.
