Aon is nearing a roughly $17 billion deal to buy insurance brokerage USI from KKR, marking one of the biggest reported moves in the sector this year. The transaction, if completed, would bring USI into Aon’s orbit in a deal that has drawn attention because of its size and the companies involved.
The figure matters because $17 billion is not a routine purchase price; it signals a major bet on scale and consolidation. In a market where brokerage assets are often valued for client relationships and recurring revenue, a deal of that size would stand out even before the final paperwork is done.
That said, the transaction is being described as nearing completion, not finished. The missing pieces are still the ones that matter most: whether the acquisition is formally signed off and what terms ultimately govern the transfer of USI from KKR to Aon.
For readers searching Aon UK&I now, the reason is simple: this is a large, specific M&A development, and the market has been given a price tag but not a clean final answer. Until that changes, the story is less about a closed acquisition than about how close Aon has come to landing it.
