Who Is the Richest Insurance Broker?

When it comes to global insurance brokerage, one name stands at the top: Marsh & McLennan. Thanks to its strategic acquisition of Jardine Lloyd Thompson Group (JLT) in 2019, Marsh solidified its position as the world’s leading insurance broker. This bold move didn’t just expand its reach—it significantly boosted its bottom line.

Before the acquisition, Marsh was already a major player. But after absorbing JLT, its total revenue leapt from $14.95 billion in 2018 to a staggering $17 billion. That kind of growth doesn’t happen overnight, and it underscores just how transformative the deal was. The merger brought together two powerhouses, combining Marsh’s global presence with JLT’s strong foothold in specialty markets across Europe, Asia, and Latin America.

Meanwhile, its closest competitor, Aon Plc, held steady in second place with $11 billion in revenue. While Aon remains a dominant force—especially in risk advisory and human capital solutions—it hasn’t matched Marsh’s recent scale. Both firms are giants in the industry, but Marsh’s aggressive expansion strategy has given it a clear edge in sheer size and market influence.

It's worth noting that “richest” in this context refers to revenue and market presence, not personal wealth. Neither Marsh nor Aon are individuals, but massive corporations employing tens of thousands worldwide. Their influence stretches far beyond brokerage—shaping how businesses manage risk, purchase coverage, and navigate an increasingly complex global landscape.

Today, Marsh & McLennan isn’t just the largest insurance broker by revenue—it’s setting the pace for the entire industry. With innovation, global reach, and a powerful post-acquisition surge, it’s hard to argue with the numbers.
