Golden Finance reports that the world's largest asset management company is increasing its bet on artificial intelligence (AI) in its U.S. model portfolio, while reducing its overall equity exposure due to tariff uncertainties. BlackRock is increasing its exposure to AI in its equity-heavy portfolio through the iShares AI Innovation and Tech Active ETF (ticker BAI). This actively managed fund attracted approximately $436 million in net inflows on Tuesday, marking the largest single-day net inflow since its inception in October last year, with the fund size expanding fourfold as a result.
