- There is substantial volatility in revenues year-over-year, with several companies entering and leaving the top 25 from one year to the next.
We got the data for our visualization from an annual list of top 100 business insurance brokerages based on revenue from Business Insurance. We ranked the companies in order of their 2018 cash flow, the last year for which complete data was available. We then color-coded the exploding pie chart by revenue level, providing a clear snapshot of the biggest players in the business insurance brokerage industry.

The first insight from our visual is just how top-heavy the business insurance market is. Marsh & McLennan clearly stands out as the largest company by annual revenue. With $7.5B in money coming in during 2018, Marsh & McLennan saw more money than all the companies in spots 11 to 25 combined. But there are a few other large, multi-billion dollar companies in the top 5, like Aon ($4.7B), Willis Towers Watson ($4B) and Arthur J. Gallagher ($3.6B).
So there are a handful or large companies at the top, but what about the other end of the spectrum? Further down the list, there are a lot of companies generating highly volatile revenue year-over-year. 12 companies in the top 25 have less than $1B in revenue. Looking further down the list from Business Insurance, 13 out of the top 50 companies saw less than $100M in annual revenue. This means that making a few key sales to large companies could dramatically improve any specific company’s place on the ranking.
And finally, a lot remains unknown about how the coronavirus pandemic will impact the business insurance industry, and which companies are going to make it through to the other side of the current economic recession. For example, one open issue is whether business insurance policies cover government-mandated closures due to the pandemic. We will see how the issue progresses through ongoing litigation, but the widespread economic downturn will surely impact revenue figures for 2020 and beyond.
