KKR wrapped up its largest-ever buyout fund with $19bn in investor commitments in a fundraising effort that broke an in-house record that has stood for more than 15 years.

The New York-based firm’s latest vehicle, KKR North America Fund XIII, is about 8% bigger than the $17.6bn it collected for its KKR 2006 Fund LP and includes about $2bn in commitments from the firm and employees on top of investor pledges. Nate Taylor, co-head of the Americas Private Equity strategy for the firm, said the fund was oversubscribed.
