Apple announced its first foldable iPhone, the Duo, on September 9, 2026, confirming a book-style design with a 5.4-inch outer display and 7.6-inch inner screen, A20 Pro chip, and pricing starting at $1,999. Pre-orders begin October 16 with shipments starting October 23, marking the end of years of rumors and supply-chain ramp-up that included mass production and expanded retailer demos. This late entry positions Apple against established rivals like Samsung’s Galaxy Z Fold series and Google’s Pixel Fold, leveraging iPad-like multitasking, minimized crease, and on-device AI features to target premium users. The confirmed timeline and production scale drive strong trader consensus on near-term release probabilities, with any remaining uncertainty tied to initial availability volumes rather than delays.
