**Apple officially unveiled its first foldable iPhone, the iPhone Duo, on September 9, 2026, during the “Surprise and Shine” event led by new CEO John Ternus.** The book-style device features a 7.6-inch inner OLED display and a compact outer screen, starts at $1,999, and ships October 23 after pre-orders begin mid-month. This followed months of supply-chain reports confirming production ramp-up despite earlier hinge and engineering concerns, with the launch aligning alongside iPhone 18 Pro models. The move positions Apple in a competitive foldable segment long led by Samsung’s Galaxy Z Fold series and Chinese rivals, emphasizing seamless multitasking, durability improvements, and integration with iOS features. Traders now focus on initial sales data, supply constraints, and whether the premium pricing sustains demand against established Android options.
