Headline: US Equity Funds See Record Inflows Amid AI Boom; Semiconductor Equipment Stocks Surge

U.S. equity funds attracted a record $119.2 billion in the week ending June 17, 2026, with technology stocks drawing a record $19.2 billion, fueled by sustained artificial intelligence enthusiasm. This influx propelled the Nasdaq 100 to a 24% year-to-date gain and the S&P 500 up 9.6%. The capital spread broadly, with mid-cap funds receiving a record $19.9 billion and small-cap funds $12.3 billion, their second-highest inflow. This reflects significant AI infrastructure investments by cloud giants like Alphabet, Amazon, and Meta. The AI rally has expanded to semiconductor equipment, with nine U.S. firms over $10 billion market cap gaining over 75% year-to-date. MKS Instruments surged 154.9%. TSMC raised its 2026 capital expenditure to nearly $56 billion, citing tight equipment supply. SK Hynix plans to double wafer capacity. Global semiconductor equipment shipments rose 14% year-over-year to $36.55 billion in Q1 2026, driven by AI.
