Apple announced its first foldable iPhone, the iPhone Duo, on September 9, 2026, during its “Surprise and Shine” event, marking the largest iPhone form-factor change since 2007. The book-style device features a 5.4-inch cover display and 7.6-inch inner screen, titanium build, A20 Pro chip, and starts at $1,999, with preorders opening October 16 and sales beginning October 23. This timeline, after roughly a decade of development, aligns with strong trader consensus on near-term release. Competitive pressure from Samsung’s Galaxy Z Fold series and Huawei models, plus Apple’s premium positioning and supply-chain focus, further supports high implied probability. Limited initial production volumes around 6–10 million units highlight the emphasis on quality over scale for the new category.
