MGA Premiums Increase in 2024, Marking Fourth Consecutive Year of Double-Digit Growth: AM Best

Managing General Agent (MGA) premiums grew by 14.5% to $89.9 billion in 2024, marking the fourth consecutive year of double-digit growth despite moderating pricing in certain insurance lines, according to AM Best.
The insurance market continues to embrace the specialized expertise offered by MGAs, with the total number of uniquely identified MGAs exceeding 700 in 2024. Market research suggests the actual number operating in the U.S. likely surpasses 1,000, as many generate annual premiums below the reporting threshold required in NAIC statements.
Specialization has emerged as a dominant trend, with approximately 55% of MGA premiums coming from firms focusing on specific lines of business or risk classes. Property specialization leads at 11% of reported MGA premiums, followed by private passenger auto (10%), crop (5.4%), general liability (5.3%), and workers’ compensation (4%), according to the report. Other notable niche specialties include cyber, flood, pet, surety/fidelity, and earthquake coverage.
The premium momentum has remained robust despite pricing moderation or declines in certain segments such as workers’ comp, professional liability (particularly directors and officers liability and employment practices liability), and cyber liability. This specialization trend shows no signs of slowing as underwriting becomes more automated and relationship-building evolves through a combination of human expertise and technological networks, AM Best found.
Market Dynamics Create Opportunities and Challenges
While the MGA segment continues to thrive, shifting market conditions are creating both opportunities and potential hurdles. The property and casualty market growth is expected to moderate in the near term, which could limit future MGA expansion and place additional pressure on newly formed or less capitalized MGAs, according to AM Best.
Recent regulatory changes are also reshaping the competitive landscape. Florida’s passage of House Bill 1549 (effective July 2025) eliminates the diligent search requirement, joining states like Virginia, Mississippi, Louisiana, and Wisconsin that have already implemented similar changes. This regulatory shift is expected to streamline MGAs’ ability to place business directly with surplus lines carriers, potentially signaling a new wave of growth for the excess and surplus lines segment.
New market entrants with expertise in niche markets continue to attract insurers with capacity and appetite for specialty risks. However, these newcomers face an increasingly competitive environment where established MGAs benefit from longstanding relationships and deeper understanding of how to price and underwrite profitable business, the report noted.
Technology and Regulatory Considerations
Technology has emerged as both an enabler and a compliance challenge for MGAs. Without the burden of legacy systems, specialist MGAs have the flexibility to invest in artificial intelligence and machine learning models that can predict and price risk in an automated manner.
However, the growing reliance on advanced technologies brings increased regulatory scrutiny, AM Best noted. Insurance companies working with MGAs need to have an appropriate understanding of the AI and machine-learning models being used, along with a clear view of the MGAs’ cybersecurity posture.
Regulatory oversight of machine learning and generative AI models requires thoughtful implementation and careful validation to ensure models are appropriate for their intended use. The use of Big Data means MGAs acting as data custodians must respect consumer privacy and implement strong cybersecurity measures.
Regulators may ultimately require insurance companies to understand and explain the underwriting and pricing models since the risk is ultimately assumed by the insurers. This creates an imperative for transparency in algorithmic decision-making and data management practices.
As carriers increasingly partner with MGAs to create specialized programs, particularly in stable commercial and personal lines of coverage, the balance between technological innovation and regulatory compliance will remain a critical factor in sustaining the sector’s impressive growth trajectory.
