These rankings serve as crucial industry benchmarks that highlight market trends and competitive positioning. The top 10 US brokers generated an impressive $49.9 billion in revenue, representing 66% of the total top 100 revenue ($75.5 billion), according to MarshBerry data.

For clients, these rankings provide valuable insights into:

Global Insurance Broker Landscape

The international insurance brokerage market continues to evolve with clear industry leaders maintaining dominance while strategic consolidations reshape competitive dynamics. Revenue growth, global footprints, and evolving client relationships define the current marketplace.

Top Global Insurance Brokers

Marsh McLennan leads the global insurance brokerage rankings with an impressive $22.7 billion in revenue as of 2024. This positions them firmly at the top of the industry hierarchy, followed by Aon with $13.4 billion in revenue.

The top global brokers for 2024 include:

1. Marsh McLennan – $22.7 billion (CEO: John Doyle, Headquarters: New York, NY)
2. Aon – $13.4 billion
3. Willis Towers Watson
4. Gallagher

These top global insurance brokers maintain dominance through extensive service offerings spanning insurance, reinsurance, and risk management solutions. Each provides specialized expertise across multiple industries and geographical regions.

The 2025 ranking is already showing changes with three new entrants: Steadfast Group (#17), AUB Group (#18), and BMS Group (#20), reflecting the dynamic nature of the industry landscape.

Evolving Relationships in Brokerage

Today’s insurance brokers are transforming their client relationships from traditional intermediaries to strategic advisors. This shift reflects changing client expectations and competitive pressures in the marketplace.

Brokers now offer expanded services beyond policy placement, including:

• Risk analytics and modeling
• Claims advocacy
• Loss control consulting
• Alternative risk financing solutions

Digital transformation has significantly impacted how brokers interact with both clients and insurers. Data analytics capabilities have become critical differentiators, enabling brokers to provide more personalized recommendations and risk insights.

Many leading brokers now position themselves as holistic risk management partners rather than simply insurance intermediaries. This evolution has helped them maintain relevance and drive revenue growth despite increasing marketplace pressures.

Consolidation Trends

The global brokerage market continues to experience significant consolidation activity. Larger firms regularly acquire smaller specialists to expand geographical reach, enhance technical capabilities, or enter niche markets.

Key drivers of consolidation include:

• Economies of scale
• Technology investment requirements
• Competitive pressure
• Private equity interest

Between 2020-2024, hundreds of brokerage acquisitions occurred annually, dramatically reshaping the competitive landscape. Mid-market brokers face increasing pressure either to sell or scale significantly to remain competitive.

The global insurance brokerage industry is seeing many regional players absorbed into larger organizations as part of this ongoing consolidation wave. This trend shows no signs of slowing, with private equity firms remaining particularly active investors in the sector.

Regulatory scrutiny of major mergers has increased, with authorities examining potential impacts on market competition and client choice.

Market Dynamics and Performance

Insurance brokerage showed remarkable resilience in 2024 with revenue growth across the top firms. The market continues to be influenced by rate fluctuations, changing premium structures, and expansion in specialty markets.

Rate Increases and Market Cycles

The insurance broker market in 2024 has experienced significant rate increases across multiple lines. Property coverage saw the most dramatic shifts, with rates increasing 10-15% in catastrophe-prone regions. This continues the hard market cycle that began in late 2022.

Commercial auto and liability rates also climbed 5-8% on average throughout 2024. These increases have directly benefited major brokers like Marsh McLennan and Aon PLC, whose revenue models are partially commission-based.

Smaller regional brokers have faced more challenges navigating these rate increases. Many have responded by enhancing their risk management advisory services to provide additional value to clients facing premium hikes.

Insurance Pricing Trends

Premium growth remained high in 2024, creating favorable conditions for brokers across the board. According to market analysis, premiums are expected to maintain growth just below 2023 levels, providing continued market tailwind for brokers.

The top 10 US brokers generated approximately $49.9 billion in revenue, representing 66% of the $75.5 billion total revenue among the top 100 firms. This concentration demonstrates the continuing consolidation within the industry.

Key Premium Trends by Line:

• Cyber insurance: +15-20%
• Directors & Officers: +3-5%
• Workers’ Compensation: Flat to -2%
• Professional Liability: +5-8%

Brokers with specialized expertise in high-growth lines have outperformed generalists. This explains why firms like Hub International and Brown & Brown have risen in the rankings.

Surplus Lines Growth

The surplus lines market expanded significantly in 2024, creating new opportunities for brokers with wholesale capabilities. Estimates indicate a 12% growth in surplus premiums compared to 2023, exceeding standard market growth rates.

This expansion primarily stems from increased placement of challenging risks and emerging exposures that standard carriers have been reluctant to underwrite. Climate-related property risks, cryptocurrency businesses, and cannabis operations represent major drivers.

Marsh & McLennan and Arthur J. Gallagher have strategically invested in their wholesale divisions to capitalize on this trend. Their wholesale operations contributed approximately 15-20% to their overall revenue growth in 2024.

Many mid-sized brokers have formed strategic partnerships with wholesale specialists to access these markets without direct investment in new infrastructure.

Sector-Specific Broker Rankings

Insurance brokers specialize in different market segments, offering targeted expertise to clients with specific needs. These specialized rankings highlight the most effective brokers across key insurance categories in 2024.

Commercial Insurance Brokers

The commercial insurance brokerage space continues to be dominated by industry giants in 2024. Marsh & McLennan ranks first among commercial brokers, followed closely by Aon PLC and Arthur J. Gallagher & Co.

Commercial property and liability coverage expertise has become particularly valuable for brokers serving large corporations. Chubb Ltd. leads commercial premiums written with 5.5% market share, while Travelers follows at 5.2%.

Industry specialists note that the most successful commercial brokers offer comprehensive risk assessment tools alongside traditional placement services. These top firms have invested heavily in data analytics capabilities to quantify client exposures more precisely.

Regional commercial brokers showing notable growth include mid-sized firms specializing in specific industries such as manufacturing, technology, and healthcare. Their sector-specific expertise often provides significant value to clients operating in complex regulatory environments.

Life and Health Insurance Brokers

Life and health insurance brokerage rankings show significant movement in 2024, with several firms investing heavily in technology solutions. Digital platforms that streamline enrollment and claims processes have become competitive differentiators.

Employee benefits specialists dominate this category, with firms focusing on corporate wellness programs and integrated health solutions. Top performers excel at navigating the complexities of healthcare compliance while delivering cost containment strategies.

The market leaders have expanded their consulting services beyond traditional insurance placement. They now offer comprehensive absence management, pharmacy benefit optimization, and mental health service coordination.

Several brokers have developed specialized expertise in serving aging populations with Medicare supplement products. This demographic focus has proven profitable as baby boomers continue transitioning to retirement benefits.

Small business health insurance specialists have also gained traction by simplifying complex healthcare decisions for companies with limited HR resources. Their technology platforms allow easy comparison of plan options and streamlined enrollment processes.

Casualty Insurance Brokers

The casualty insurance brokerage segment has experienced significant consolidation, with the top firms controlling a larger market share than in previous years. Workers’ compensation specialists lead this category, offering injury prevention programs alongside traditional coverage placement.

Auto liability experts have gained prominence as commercial fleet risks grow more complex. Top casualty brokers provide telematics solutions that monitor driver behavior and identify risk factors before accidents occur.

Top Casualty Brokers by Specialty:

• Workers’ Compensation
• General Liability
• Auto Liability
• Umbrella/Excess Liability
• Environmental Liability

Middle-market casualty brokers have found success by focusing on industry-specific risk profiles. Construction, transportation, and hospitality specialists have developed targeted solutions that address unique exposures in these sectors.

Claims advocacy has become a crucial differentiator among leading casualty brokers. The highest-ranked firms employ specialized teams that maximize claim recoveries and minimize settlement times for clients.

Specialty Coverage Experts

Specialty insurance brokers focus on niche markets requiring deep technical expertise. Cyber liability specialists dominate this category in 2024, with top global brokers developing proprietary assessment tools to quantify digital exposures.

Professional liability experts serving legal, medical, and technology professionals have created tailored coverage structures addressing emerging risks. These specialized brokers understand nuanced exposures that general practitioners might overlook.

Marine and aviation specialists maintain their distinct market positions, with few new entrants challenging established firms. These technical specialties require years of experience and global relationships to serve clients effectively.

Climate risk specialists have emerged as a growing specialty segment. These brokers help clients navigate the complexities of parametric insurance, carbon offset guarantees, and sustainability-linked coverage structures.

The most successful specialty brokers combine deep technical knowledge with innovative coverage structures. They often collaborate with underwriters to develop customized policies addressing emerging risks that standard markets cannot adequately cover.

Operational Excellence in Brokerage Firms

Top insurance brokers achieve their rankings through superior operational practices that strengthen client relationships and financial outcomes. These firms excel by implementing systematic approaches to crucial business functions.

Asset Management and Financial Health

Leading brokerage firms implement sophisticated asset management strategies to maintain strong financial health. The top global insurance brokers like Marsh McLennan and Aon maintain substantial capital reserves to weather market fluctuations and seize growth opportunities.

These firms typically employ dedicated financial teams who maximize returns on premium float—the money held between collection and remittance to carriers. This creates additional revenue streams beyond commission income.

Investment diversification is another hallmark of operational excellence. Top-performing brokers balance risk through varied investment portfolios spanning different asset classes and markets.

Many leading brokers also reinvest profits strategically into technology infrastructure and talent acquisition. This practice strengthens their competitive position while creating barriers to entry for smaller firms.

Claims Management and Underwriting Loss Control

Elite insurance brokers differentiate themselves through superior claims management and loss control services. These services often determine client satisfaction and retention rates.

The most successful brokers employ specialized claims advocates who work exclusively on behalf of policyholders. These advocates typically possess deep expertise in specific industries represented in the broker’s client portfolio.

Loss control teams at premier brokerage firms analyze client operations to identify and mitigate risks before they become claims. These preventative measures often include:

• On-site safety inspections and recommendations
• Employee training programs
• Industry-specific risk assessment tools
• Customized risk management technology platforms

Claims data analytics represents another area where top brokers excel. By analyzing patterns across thousands of claims, these firms help clients understand their risk exposures and implement targeted risk mitigation strategies.

Insurance Accounting and Financial Reporting

Sophisticated accounting practices are fundamental to operational excellence in insurance brokerage. The largest global brokers maintain rigorous accounting systems to track premium flows, commission income, and client funds with complete accuracy.

Advanced brokers utilize specialized insurance accounting software that automates complex calculations like earned premium allocation and commission splitting. This technology reduces errors while improving financial transparency.

Regulatory compliance represents a critical accounting function. Top brokers invest heavily in compliance teams who ensure adherence to industry regulations regarding client funds handling and financial disclosures.

Financial reporting at elite firms goes beyond basic requirements. These brokers provide clients with customized reports showing premium allocation, claims history, and risk benchmarking against industry peers. This transparency builds trust and helps clients make informed risk management decisions.

Regulatory and Economic Influences

The insurance brokerage landscape in 2024 is being shaped by significant regulatory updates, shifting interest rate environments, and the ongoing challenge of social inflation. These factors are directly influencing broker operations, client relationships, and ultimately, market rankings.

Regulatory Changes Impacting Brokers

New compliance requirements implemented in early 2024 have created both challenges and opportunities for insurance brokers. The SEC’s enhanced disclosure regulations now demand greater transparency from brokers regarding compensation structures and potential conflicts of interest. This has particularly impacted the top 10 global brokers, who have invested heavily in compliance infrastructure.

State-level regulatory divergence continues to complicate operations for multi-state brokers. California and New York have introduced stricter data privacy regulations, forcing brokers to adapt their client data management practices.

The FTC’s increased scrutiny of broker consolidation has slowed M&A activity among middle-market firms. Large brokers like Marsh McLennan and Aon now face enhanced regulatory review for acquisitions.

Interest Rate Effects on the Insurance Market

The ongoing interest rate environment has significantly influenced insurance carrier capacity and pricing in 2024. Higher sustained rates have improved carrier investment returns, creating more favorable conditions for certain coverage lines.

Property insurance has seen modest rate decreases of 3-7% in non-catastrophe zones as carriers deploy new capital. However, cyber insurance rates remain elevated despite increased capacity, with the top brokers reporting average increases of 8-12%.

The interest rate environment has also affected broker valuations and M&A activity. According to S&P Global, broker acquisition multiples have decreased slightly from their 2022-2023 peaks, though remain historically high at 8-10x EBITDA for quality firms.

Mid-sized regional brokers have faced increased cost of capital, creating competitive advantages for larger firms with established credit facilities.

Social Inflation and Its Implications

Social inflation continues to significantly impact broker operations and client relationships in 2024. Average commercial liability claims have increased approximately 15% year-over-year, outpacing general inflation.

Brokers now dedicate more resources to claims advocacy, with leading firms expanding their claims departments by 10-20% since 2022. This trend is particularly pronounced in sectors facing high litigation exposure such as healthcare and transportation.

Client education has become a crucial differentiator for top-performing brokers. Firms like Hub International and Brown & Brown have developed specialized training programs to help clients navigate increasing liability exposures.

Data analytics capabilities have become essential for effectively addressing social inflation. Brokers with advanced analytics platforms can better identify trends and provide clients with more accurate risk forecasting.

Innovation and Technology in Brokerage

Technology has transformed the insurance brokerage landscape in 2024, creating new efficiencies and service models. Brokers now use advanced tools to provide more personalized solutions and streamlined processes for clients.

AI Platforms for Enhanced Brokerage Services

The insurance industry anticipates a transformative shift in 2024, with AI platforms becoming essential tools for top brokers. Leading firms like Marsh McLennan and Aon have integrated sophisticated AI systems that analyze client data to predict risk patterns and recommend optimal coverage options.

These platforms enable brokers to offer hyper-personalized policies based on specific business operations rather than generic industry templates. For example, AI systems can:

• Analyze decades of claims data in seconds
• Identify coverage gaps unique to client operations
• Generate risk assessment reports with actionable recommendations

Data analytics and AI integration now allow brokers to provide more accurate risk assessments, helping clients understand potential exposures before they become costly claims.

Tech-Driven Efficiency in Asset and Claims Management

The brokerage industry has been forced to innovate due to technological advances and changing client expectations. Today’s leading brokers employ digital platforms that streamline the entire claims management process.

Mobile apps now allow clients to:

• Submit claims with photo documentation
• Track claim status in real-time
• Communicate directly with adjusters

Digital asset management systems have revolutionized how brokers track client property and assess valuations. These platforms automatically update asset values based on market conditions and can trigger coverage adjustment recommendations when assets change.

Claims processing times have decreased by nearly 40% among brokers utilizing automated workflows, with some routine claims receiving same-day approval. This efficiency translates to improved client satisfaction and reduced administrative costs for the top global insurance brokers.

Insight Into Broker Mergers and Acquisitions

The insurance brokerage sector continues to experience significant consolidation through mergers and acquisitions, reshaping the competitive landscape. M&A activity reached notable highs in 2024, with strategic investments driving industry transformation.

Strategic Investment and Its Role

Insurance brokerage M&A transactions in the US reached 849 deals by the end of 2024, marking a 5.2% increase compared to 2023. This surge reflects the growing interest in strategic acquisitions as a means to expand market reach and service capabilities.

Top brokers like Marsh McLennan and Arthur J. Gallagher have utilized strategic investments to strengthen their market positions. These investments allow brokers to:

• Acquire specialized expertise in niche markets
• Expand geographic footprint
• Enhance technological capabilities
• Achieve economies of scale

Large brokers often target mid-sized firms with strong client relationships and specialized knowledge. This approach enables immediate revenue growth while minimizing competitive risks.

Brokerage Landscape Post M&A

The concentration of power among the largest brokers continues to intensify. The top 10 US brokers generated a combined revenue of $49.9 billion, representing 66% of the total revenue across the top 100 brokers ($75.5 billion).

This consolidation has created a two-tiered market structure. At the top, global giants like Marsh McLennan, Aon, and Arthur J. Gallagher dominate with comprehensive service offerings and international reach.

Meanwhile, smaller regional brokers face increasing pressure to differentiate themselves or become acquisition targets. Many have responded by:

1. Specializing in specific industries or risk types
2. Investing in digital capabilities
3. Forming strategic partnerships
4. Focusing on personalized service and local relationships

The post-M&A landscape favors brokers with clear strategic direction and the ability to integrate acquisitions effectively.

Human Resource Dynamics

The insurance brokerage industry faces unique human resource challenges in 2024 that directly impact business performance and market positioning. Talent strategies and leadership transitions have become critical differentiators for top-ranked brokers.

Talent Development and Retention in Brokerage Firms

Leading insurance brokers invest heavily in talent development programs to maintain competitive advantage. Marsh McLennan, the top-ranked global broker in 2024, attributes part of its success to robust employee development initiatives that help retain industry expertise.

Competition for specialized talent remains fierce among the top 10 brokers. Many firms have implemented:

• Advanced technical training programs
• Mentorship opportunities
• Digital skill enhancement workshops
• Career progression frameworks

Insurance brokerage firms face 15-20% higher talent acquisition costs in 2024 compared to previous years. This has pushed companies to improve retention strategies beyond compensation.

Work flexibility has emerged as a key retention factor, with 73% of brokerage employees rating it as “highly important” in recent industry surveys.

Impact of Executive Changes

Executive leadership transitions significantly influence broker performance and market perception. In 2024, several top-ranked brokers experienced leadership changes that affected their strategic direction and client relationships.

When John Doyle became president and CEO at Marsh McLennan, the firm strengthened its digital transformation initiatives. This leadership shift helped maintain their #1 position in the global rankings.

Executive changes often trigger:

Positive Impacts

• Fresh strategic perspectives
• Enhanced innovation approaches
• New client relationship opportunities

Potential Challenges

• Temporary organizational disruption
• Client relationship transitions
• Market perception uncertainties

Broker stability during leadership transitions correlates strongly with market performance. Firms with well-planned succession strategies typically maintain or improve their ranking positions in the following year.

Emerging and Niche Markets

Insurance brokers are expanding their offerings beyond traditional coverage areas to capture specialized market segments that show significant growth potential. These niche markets represent valuable opportunities for brokers to diversify their portfolios and increase revenue streams.

Pet Insurance Market Trends

The pet insurance sector has emerged as one of the fastest-growing niche markets in 2024. Industry analysts report a 15% year-over-year growth rate, far outpacing traditional insurance segments. This expansion correlates directly with increasing pet ownership and growing consumer willingness to invest in companion animal healthcare.

Leading brokers like Marsh McLennan and Arthur J. Gallagher have developed specialized pet insurance divisions to capitalize on this trend. Their offerings typically include:

• Accident and illness coverage (most popular)
• Wellness plans (preventative care)
• Breed-specific policies (addressing hereditary conditions)

Small to mid-sized brokerages often partner with veterinary practices to create bundled service packages. Premium rates increased by an average of 7.3% in Q2 2024, reflecting the robust demand in this segment.

Retirement and Pension Market Developments

The retirement insurance brokerage landscape has transformed significantly in 2024, driven by demographic shifts and regulatory changes. Brokers specializing in this niche have seen 9% revenue growth as businesses seek expert guidance navigating complex pension obligations.

Willis Towers Watson and Aon lead in retirement solution innovations, particularly through:

1. Defined contribution plan management tools
2. Longevity risk transfer solutions
3. ESG-integrated pension products

Digital platforms have become essential for retirement portfolio management. According to Q2 2024 market updates, 73% of top brokers now offer mobile accessibility for clients to monitor retirement investments.

Regional brokers increasingly specialize in small business retirement planning, filling a gap left by larger firms focused on enterprise clients.
