TOP 20 Global Re/Insurance Brokers

Marsh McLennan retains the #1 spot in Best’s Review’s Top Global Insurance Brokers ranking 2024 with $19.8 bn in total revenues, $7.6 bn ahead of second-place AON. The expected Aon/WTW combination deal that would have substantially affected this year’s brokers ranking was scuttled last July after regulatory involvement, according to A.M. Best data.

Global insurance and reinsurance brokers play a pivotal role in the insurance industry, serving as intermediaries that facilitate the placement of insurance and reinsurance coverages for their clients with insurers and reinsurers.

According to Beinsure Data, the value of the worldwide market for insurance broking in terms of fees and commissions earned was around USD 160.4 bn in 2023, up from around USD 152 bn in 2022, equivalent to a growth rate of almost 10.5% without adjusting for inflation, but closer to 2% as an inflation-adjusted measure.

In the ranking, the TOP 5 remained the same as last year. However, there was a shuffle in the bottom half of the top 10. Acrisure LLC moved from #9 to #7; Alliant Insurance Services Inc. jumped from 11th place to the eighth spot; Truist Insurance Holdings Inc. dropped to #9 from #7; and Lockton Inc. moved from #8 to #10.
