Investment giant Apollo Global Management is reportedly finalizing a deal to acquire a nearly 10% stake in Mubadala Capital, the alternative asset management arm of Abu Dhabi sovereign wealth fund Mubadala Investment Company, according to sources familiar with the matter. Mubadala Capital manages over $755 billion in assets, with its core alternative investment business having grown to over $60 billion. The transaction is expected to be announced later on Monday morning, with specific financial terms not yet disclosed. This move will further deepen Apollo's presence in Abu Dhabi and marks a significant shift in the relationship between U.S. investment firms and the Middle East, with American companies making substantial direct investments in the country and its investment vision.
