Market size
Fortune Business Insights estimated the global insurance brokerage market at $125.36 billion in 2025. Other published estimates are higher because they include broader insurance-agent, distribution-platform and intermediary revenues; for example, Global Market Insights estimated the insurance brokers and agents market at $276.5 billion in 2025.[66][67]
Forecast & CAGR
The market is projected to grow from $125.36 billion in 2025 to $282.45 billion in 2034, representing a 9.5% compound annual growth rate from 2026 to 2034. A broader brokers-and-agents definition from Global Market Insights implies a 9.1% CAGR from 2026 to 2035.[66][67]
Market share & regions
North America accounted for 37.5% of the global insurance brokerage market in 2025 under Fortune Business Insights' definition. A separate 2024 MarketLine estimate for the broader global insurance brokers sector assigned 74.3% to North America, 17.0% to Europe and 6.2% to Asia-Pacific, illustrating the effect of differing scopes.[66][68]
Segmentation
The market is segmented by broker type into retail, wholesale and reinsurance brokerage; by insurance type into life and health, property and liability, auto, home, travel and cyber insurance; and by end user into business-to-business and business-to-consumer customers. Fortune Business Insights also distinguishes online and offline distribution channels.[66]
Key players & concentration
The Insurance Information Institute's 2024 ranking placed Marsh McLennan first among global brokers with $25.331 billion in brokerage and related-services revenue, followed by Aon at $15.382 billion and Arthur J. Gallagher at $11.082 billion. Insuramore estimated that the 15 largest broking groups controlled 48.7% of global broking fees and commissions in 2024.[69][54]
Pricing
Broker remuneration commonly combines insurer-paid commissions, client fees and negotiated placement fees. In Europe, MarshBerry reported typical commission ranges of 10%–20% of annual premium for property and casualty insurance, 5%–15% for life insurance and 3%–8% for health insurance; commercial, specialty and reinsurance fees are often negotiated transaction by transaction.[46]
Trends, drivers & challenges
Demand is being supported by complex commercial risks, cyber exposure, climate-related losses and the need for risk-management advice, while brokers are investing in automation and digital servicing. In a 2025 First Connect survey, 81% of independent agents reported higher customer expectations for speed, and 86% reported challenges with product availability in their markets.[70][28]
Consumer behavior & competition
Digital comparison and servicing are increasing competitive pressure, but human advice remains important for complex coverage. J.D. Power reported that 47% of U.S. auto policy buyers purchased through digital channels in 2025, compared with 35% through agents and 17% through call centers; 57% had actively shopped for a new policy during the preceding year.[71]
M&A
Brokerage consolidation remained active in 2026: Aon agreed on August 31, 2026, to acquire USI Insurance Services from KKR for approximately $17 billion, with USI reported at about $3 billion in annual revenue and more than 10,500 employees. Gallagher said it completed 33 mergers in 2025 representing more than $3.5 billion in estimated annualized revenue.[72][22]
Regulation
Insurance brokers are subject to jurisdiction-specific licensing, conduct, remuneration-disclosure and competency requirements. The U.K. FCA's current guidance applies the Insurance Distribution Directive framework to firms carrying out insurance distribution activities, while its rules require firms to provide information about services and remuneration.[73]
Latest news
The most significant recent brokerage-industry announcement identified was Aon's proposed $17 billion acquisition of USI on August 31, 2026. The deal would deepen Aon's position in the U.S. middle-market brokerage segment and follows its acquisition of NFP in 2024.[72][46]
