BlackRock pushed deeper into private markets Monday with the acquisition of commercial real estate firm ElmTree Funds.

The deal gives the investment firm $7.3 billion in assets as it attempts to broaden its holdings of private assets, following BlackRock’s announcement last week of a new all-in-one 401(k) target date fund with private equity.

The real estate-focused firm will be added to an internal BlackRock group that now includes HPS Investment Partners.
