AI concept stocks pull back as Wall Street banks demand additional collateral from some hedge funds

Harvard University Investment Management Company disclosed that it holds $2.2 billion worth of SpaceX shares, making it the largest single stock position in its $4.3 billion US equity portfolio. This holding originated from Harvard’s early investment in SpaceX through venture capital funds, and the position has significantly appreciated after SpaceX’s public listing in June this year. The University of California also disclosed a roughly $1 billion position in SpaceX during the same period. Over the past decade, endowment funds from several universities have made substantial bets on private tech assets.
