Apple announced its first foldable iPhone, the iPhone Duo, on September 9, 2026, alongside the iPhone 18 Pro models, with preorders opening October 16 and availability starting October 23. The book-style device features a 7.6-inch inner display, A20 Pro chip, titanium build, and starts at $1,999, positioning Apple to capture substantial share in a category long led by Samsung. New CEO John Ternus highlighted productivity features like multi-window support and privacy advantages. This confirmed launch, after years of development since at least 2017, aligns with supply chain reports and analyst expectations for strong initial demand, though limited early availability could influence short-term sentiment ahead of broader rollout.
