Apple’s official September 2026 unveiling of the iPhone Duo, its first book-style foldable with a 5.5-inch cover display and 7.6–7.8-inch inner screen, has anchored trader sentiment around near-certain release by late 2026. Announced at the “Surprise and Shine” event alongside iPhone 18 Pro models, the device features an A20 Pro chip, titanium frame, Touch ID power button, and $1,999 starting price, with pre-orders opening October 16 and retail availability October 23. Supply-chain reports confirm mass production ramped up without major delays, while competitive pressure from Samsung, Huawei, and others accelerated Apple’s timeline after years of internal development. Upcoming catalysts include initial sales figures and any noted production constraints that could affect volume but not the core launch window.
