Key points

  • Aon to buy USI Insurance Services for $17 billion
  • Seller is private equity firm KKR
  • Announced Monday, August 31, 2026
  • USI is described as a rival insurance brokerage

Aon said on Monday it will buy rival USI Insurance Services in a $17 billion deal from private equity firm KKR. The acquisition, announced by the insurance brokerage, marks one of the largest transactions in the sector this year.

The deal brings together two major players in the insurance brokerage market. USI, which has been owned by KKR, will become part of Aon's operations, though the companies did not disclose further terms beyond the purchase price.

A $17 billion price tag

The all-cash transaction values USI at $17 billion, according to Aon's announcement. The price reflects the scale of USI's business and its position as a rival to Aon in the brokerage space.

KKR exits its investment

KKR, which has held USI as a portfolio company, will sell its stake as part of the deal. The private equity firm's exit comes after a period of ownership that saw USI grow its operations.

What happens next

The deal is subject to regulatory approvals and other customary closing conditions. Aon and USI have not provided a timeline for when the transaction is expected to close, leaving the completion date as the key open question.

Why it matters

The acquisition would significantly expand Aon's brokerage operations, potentially reshaping competition in the insurance brokerage sector. The involvement of KKR highlights the continued role of private equity in consolidating the industry.
