BlackRock Reworks $300 Billion Model Portfolios as AI Trade Broadens

BlackRock is adjusting a series of model portfolios with about $300 billion in assets, adding U.S. large-cap equity exposure while shifting part of its artificial-intelligence positioning from early AI leaders toward companies adopting or benefiting from the technology. The move shows how one of the world’s largest asset managers is treating AI less as a narrow semiconductor-and-megacap theme and more as a wider portfolio force spanning equities, credit and alternative strategies.
