Trade and regulation set the tone: U.S. and Chinese officials may discuss AI cyberattacks and chip controls at September 24 talks, while DOJ examines Nvidia’s 2025 Groq deal and Google blames EU rules for weaker search. Regulators also sought more information on Fox’s $22B Roku takeover. Corporate activity included Bending Spoons’ $1.36B Miro acquisition, Chime’s $590M Stride Bank purchase, Nasdaq’s $100M investment in Kraken parent Payward at a $21B valuation, and Robinhood’s first underwriting role in Oura’s $11B+ IPO. Tech firms are considering Patagonia data-center plans, while TSMC turned to additional ASML lithography machines to ease chip shortages. At Apple’s first fall event under CEO John Ternus, the $1,999 iPhone Duo led a slate spanning a variable-aperture iPhone 18 Pro camera, Apple Watch conversation recall, AirPods 5 noise cancellation, and an AI-powered Health redesign.
