Institutions Boost AI Infrastructure, Semiconductor Holdings in Q1 2026 Filings

Reuters' review of about 6,000 Q1 2026 13F filings shows institutional investors broadly increased exposure to AI infrastructure, data-center, utility, and semiconductor stocks. Over 4,000 firms added or initiated positions in nine AI infrastructure names, dwarfing the 146 (≈2.5%) that reduced holdings, while semiconductors drew over 4,100 buyers and utilities saw ~3,500 net buyers. This flow-driven demand supported AI hardware plays amid net selling in some mega-cap AI names. Notable moves included Mubadala Capital's $9.9m Palantir initiation and Shopify purchases, signaling potential underpinning for sector rallies.
