How the industry makes money

Brokers place clients' insurance with carriers and earn commissions and fees without taking underwriting risk. Revenue grows with insurance prices and client growth, and needs little capital.

Where the moats are

Expertise and relationships, counted as intangible assets, appear in all 12 moat-rated companies, and switching costs in 11: large clients rarely move complex programs built over years.

  • Marsh & McLennan, Aon and Gallagher: global brokers whose scale, data and specialist expertise large clients rely on.

The narrow-moat group includes Willis Towers Watson, Brown & Brown, Erie Indemnity and Ryan Specialty. Companies without a moat include Waterdrop and Huize. Erie Indemnity, rated narrow, scores 67 on MoatScope's quality scale.

What wears moats down

When insurance prices soften, commission growth slows. Acquisitions drive much of the industry's growth and can be overpaid for, and digital distribution competes for smaller clients.

What to watch

  • Insurance pricing trends.
  • Organic revenue growth.
  • Acquisition activity and prices.

Market share

Businesses ranked by revenue, with each one's share of the market's total: companies filed under this industry, the segments of companies filed elsewhere that compete in it, and the largest companies MoatScope doesn't cover, such as private companies and companies listed outside the US. Each market's total comes from a cited source and covers the geography its businesses compete in (a national market counts only US revenue). A company that runs several businesses is split by the segments it reports.

Global market · $180.0B total revenue in 2024 · source: Insurance-Canada.ca. Shares are of the whole market, including companies MoatScope doesn't cover; company revenue is for the fiscal year closest to 2025. 2024 broking fees and commissions worldwide; Marsh McLennan and Aon also earn consulting revenue, so their shares read high.

Market share is a company's revenue in its main market as a share of that market's total: every company in it, including private companies and companies listed outside the US (sources under each market above). Revenue is for the fiscal year closest to 2025, and a market that is national (such as US banking) counts only US revenue. Companies that run several businesses are split by the segments they report, and each segment counts in its own market. A dash means the market has no reliable total yet, or no revenue was reported for that year.

Price versus fair value for every company is in the screener.
