Apple announced its first foldable iPhone, the iPhone Duo (also referred to as iPhone Ultra), at the September 2026 event alongside iPhone 18 Pro models, with preorders starting October 16 and availability on October 23. This confirmation, following years of supply-chain reports and a decade of internal development, has solidified trader consensus around near-term release, especially given Apple's refined book-style design with a 5.5-inch cover display, 7.8-inch inner panel, A20 chip, and premium pricing near $2,000. Competitive pressure from Samsung's established foldables and production targets of 6-10 million units initially underscore the move, while the split 2027 iPhone launch cycle and plans for a second-generation model in 2027 highlight Apple's commitment to the category despite typical hardware delays.
