Leading insurance brokers worldwide by revenue distribution
The two largest insurance brokers in the world as of 2021 - March & McLennan and Aon - made the largest portion of their brokerage revenue from commercial insurance during that year. For both companies, by far the second largest revenue stream was employee benefits. This situation was reversed for third-placed Willis Towers Watson, who made over half their revenue from employee benefits, and just over a quarter from commercial insurance.
