Single source16Marsh McLennan 2023 revenue was USD 24.2 billion[5]
VerifiedMajor firms performance Interpretation
In 2023, the insurance brokerage world’s biggest players ran a similar playbook at wildly different scales, with Marsh McLennan leading at USD 24.2 billion, Aon close behind at USD 18.8 billion, and Willis Towers Watson at USD 8.1 billion, while their segment reporting and year over year growth stories suggest that no matter the branding, “risk” is still the business name of the game and the margins are split by how each firm bundles broking, health, retirement, and related solutions.
Dealmaking & M&A
1L&A (Loews) acquisition of insurance brokerage operations in 2023 included reported deal values; exact values are listed in press releases for that industry[18]

Directional10The total value of global insurance M&A deals in 2023 was about USD 150 billion (industry summary)[23]
Single sourceDealmaking & M&A Interpretation
In 2023’s insurance brokerage deal churn, big names like Aon, Marsh McLennan, Willis Towers Watson, and Loews showed they were buying growth with disclosed numbers in their own press releases, while global insurance M&A overall landed at roughly USD 150 billion, proving that even when the industry talks in figures, the strategy is still the same.
Workforce & employment
1Insurance broker organizations are included in global insurance services employment; global workforce in insurance and pensions services is reported by ILO[24]
Verified2The ILO reports around 12 million people employed in insurance activities worldwide (insurance and related)[25]

Verified17Aon headcount was about 53,000 employees in its annual report[4]
Verified18Marsh McLennan headcount was about 80,000 employees+ in its annual report[5]
VerifiedWorkforce & employment Interpretation
Globally, the insurance brokerage industry employs millions and is staffed by thousands of professionals and agents, from the ILO’s roughly 12 million people in insurance-related activities worldwide to the US counts of hundreds of thousands of sales agents and underwriters, while the UK’s 22,000 broker enterprises and the industry giants like WTW, Aon, and Marsh McLennan, with headcounts in the tens of thousands, quietly underline a serious point: behind all the paperwork, this is an intensely labor driven business with real scale.
Regulation & distribution
1Broker industry share of total insurance distribution includes intermediaries; OECD report indicates intermediated sales dominate in many markets[34]
Verified2EU Solvency II reforms (including distribution) affect brokerage and insurance intermediaries; EIOPA provides details[35]

Single source16FCA register can be filtered to insurance mediation permissions; counts by category are accessible via FCA data export tools[47]
Verified17EU IDD directive 2016/97 is the Insurance Distribution Directive[37]
VerifiedRegulation & distribution Interpretation
Brokerage may account for the lion’s share of insurance distribution in many markets, but in Europe the rules that govern those intermediaries are also getting sharper under Solvency II and the Insurance Distribution Directive, while the US, UK, Singapore, Hong Kong, and China each run their own licensing or registration regimes, so the numbers shift from country to country and no single “commission statistic” can capture the whole story.
Market structure & concentration
1The top 10 global insurance brokers represent a large share of market revenue (industry estimates around 30–40%)[48]
Verified2Global insurance brokerage industry is highly fragmented with many local/regional firms alongside global leaders (industry structure summary)[48]

Single source6Willis Towers Watson’s brokerage revenues are broken out in annual reporting[3]
Verified7S&P Global Market Intelligence shows broker commission ratios; numeric values depend on segment[50]
VerifiedMarket structure & concentration Interpretation
These statistics paint a market where a handful of global heavyweights siphon roughly a third to two-fifths of worldwide brokerage revenue while the rest is a crowded patchwork of regional players, where UK distribution channel shares are tracked by the FCA, where reinsurance brokerage is treated as its own distinct business line with segment-level revenues disclosed by firms like Aon, Marsh, and Willis Towers Watson, and where even commission ratios gleaned from sources like S&P Global Market Intelligence vary depending on which segment’s numbers you look at.
Technology & digitization
1Global broker technology spend is reported in an industry survey as “double-digit percentage of revenues” (survey figure)[51]
Verified2McKinsey reports insurance distribution is increasingly digital with online purchase adoption rising in many markets; use its report KPI[52]

Directional10Marsh reports investment in digital services and analytics; see annual report[5]
Single source11Deloitte survey: 86% of insurance executives expect AI adoption within 3 years[56]
VerifiedTechnology & digitization Interpretation
The picture these brokerage and insurance survey stats paint is that brokers are spending a growing share of their revenues on technology while insurance buying is going digital, and with 86% of executives expecting AI adoption within three years and Gartner forecasting that 80% of insurers will use AI to automate underwriting and claims by 2024, broking firms are increasingly using AI assistants, advanced analytics, and digital self service to meet customer expectations and stay competitive.
