In the US property and casualty (P&C) market, not all carriers are created equal – and not all are equally attractive as partners for managing general agents (MGAs), program administrators, and wholesale brokers.
Several carriers fit the bill. Between 2020 and 2024, the US P&C market has seen State Farm consolidate its lead, Progressive maintain aggressive growth, and several other major players trade off between market share and profitability, according to the IBA Property & Casualty Financial Insights Dashboard.
Ultimately, market share, underwriting discipline, and line-of-business exposure all reveal where the best opportunities exist. Those who understand the dynamics can position themselves ahead of the competition.
As the country’s largest carrier, State Farm’s dominance is unmatched. With a nearly 13 percent market share in 2024 – up from 9 percent in 2020 – the Illinois-headquartered carrier has widened its lead and commands unique distribution power. Out of the $99.3 billion direct premiums it earned in 2024, around 64 percent sat in private passenger auto and another 27 percent in homeowners multiple peril – giving it massive consumer touchpoints. For MGAs and program administrators, this scale creates access opportunities few others can match.
The trade-off? State Farm’s loss ratios have been volatile, peaking above 83 percent in 2022, and again in 2023, before settling at 75 percent in 2024, a level well above its peers. Partnering with State Farm means access to volume, but it requires tight program management to navigate underwriting swings.
In second place, Progressive offers a compelling mix of size and discipline. Like State Farm, it leans heavily on private passenger auto – at around 76 percent of its $47.1 billion 2024 premiums – with the rest largely split between commercial auto, homeowners multiple peril, and inland marine.
Founded in 1937, the Ohio-headquartered carrier has also held its ground at just over a 6 percent market share. While its share has flattened somewhat since 2020, the company’s loss ratio has been consistently stronger, indicating more stable underwriting results. For brokers and MGAs chasing growth in personal lines, Progressive represents one of the best-positioned carriers to align with.
While placed third by market share, United Services Automobile Association (USAA) remains a somewhat unique player among the top 10 carriers. With a 4.5 percent market share in 2024 it’s definitely not the largest, but it commands an enviable level of loyalty from its military-affiliated customer base. The firm’s premium mix is heavily concentrated in personal lines: more than 61 percent of its $34.8 billion book comes from private passenger auto and another 33 percent from homeowners multiple peril.
For MGAs, program administrators, and wholesale brokers, USAA represents less of a broad-based partner and more of a specialty alignment opportunity. Programs that can complement or extend USAA’s core personal lines, particularly in areas where its member base has unique needs – such as military-specific risk products, supplemental coverages, or regional property exposures – could be highly attractive.
The challenge is underwriting volatility. With nearly all of its premiums tied to just two lines, USAA’s results will ebb and flow with personal auto and homeowners cycles. But for those with tailored solutions that align with its customer segment, USAA offers an opportunity to plug into a highly engaged, loyal niche market that many carriers cannot replicate.
For those who prize long-term stability, two carriers stand out. Travelers and Chubb are both mid-sized by market share – with neither cracking the top five – but they consistently outperform their larger peers in underwriting, demonstrating strong discipline in managing losses.
Travelers has steadily built its market share each year following the outbreak of the pandemic, from 3.4 percent in 2021 to 3.9 percent in 2024. The firm earned the majority of its $30.3 billion 2024 premiums across commercial multiple peril (17.8 percent), private passenger auto (14.8 percent), commercial auto (12.2 percent), and workers’ compensation (11.6 percent).
Furthermore, the New York-headquartered carrier has boasted the lowest loss ratio each year from 2022, coming in at just 52.6 percent in 2024. This offers a proven foundation for sustainable program growth.
While Chubb has an even smaller market share – at just 3.6 percent in 2024 – the $28.2 billion premiums it earned in 2024 was similarly diversified through meaningful exposure to homeowners multiple peril (13.2 percent), commercial multiple peril (11.9 percent), crop (9.8 percent), and workers’ compensation (6.7 percent). Its 59 percent loss ratio in 2024 underscores why it’s a go-to choice for disciplined, profitable growth.
For MGAs and program administrators, these carriers represent the “safer bets” for building specialty programs without the volatility risk tied to over-concentration in the personal auto line.
While the largest carriers draw attention for their size and scale, mid-tier carriers such as Liberty Mutual, Farmers Insurance, and American Family bring targeted opportunities. Their portfolios are more balanced across lines, often leaning into property and specialty risks that create space for innovative programs and MGA partnerships.
Liberty Mutual, with a 4.3 percent market share in 2024 and $34.9 billion in premiums, stands out for diversification. Homeowners multiple peril (24.7 percent) and private passenger auto (23.1 percent) anchor its book, while inland marine, commercial auto, and liability lines add meaningful breadth. With a 2024 loss ratio of 62.2 percent, Liberty combines steady underwriting with a versatile appetite across both personal and commercial lines.
Farmers Insurance tilts more toward personal lines, with 42 percent of its $23.6 billion in premiums coming from private passenger auto and 36 percent from homeowners. Additional exposure to commercial multiple peril, fire, and allied lines creates entry points for small commercial programs. Its 2024 loss ratio of 54.5 percent was among the healthiest in the top 10, supporting profitable growth despite pressure in auto and property markets.
American Family Insurance Group, while the smallest of the top 10 at just over 2 percent market share, offers a distinct profile. More than half of its $16.1 billion book came from homeowners and another third from auto. This concentration carries volatility but underscores a clear appetite for property risks. With a 62 percent loss ratio in 2024, the carrier has shown disciplined results relative to peers.
For program administrators and wholesale brokers, these mid-tier carriers offer an attractive balance: large enough to provide meaningful distribution power, but nimble enough to entertain specialized programs that align with their line-of-business priorities.
For MGAs, program administrators, and wholesale brokers, these insights are more than just industry metrics – they’re roadmaps for partnership strategy.
Scale carriers such as State Farm and Progressive offer unmatched distribution reach, but their heavy reliance on auto and homeowners may leave them open to a certain degree of volatility and cycle-driven swings. They are best suited for programs that need broad market access and can tolerate slightly higher underwriting risk in exchange for volume.
By contrast, carriers like Travelers and Chubb highlight the value of underwriting discipline. Their lower loss ratios and diversified portfolios make them strong candidates for MGAs seeking long-term, stable growth in commercial lines or specialty programs.
Mid-tier carriers seem to be attempting to strike a balance. They bring meaningful scale but remain flexible enough to support innovative products and niche opportunities, especially in property, inland marine, or small commercial markets.
Ultimately, the key is alignment: MGAs and wholesale brokers should map their program ambitions to each carrier’s strategic strengths. Those who match distribution scale with underwriting appetite – and stability with innovation – will be best positioned to secure sustainable, profitable partnerships in the evolving P&C landscape.
