**Apple’s first foldable iPhone (widely expected as the “iPhone Ultra” or similar premium model) is on track for a September 9, 2026 announcement alongside the iPhone 18 Pro lineup, with sales targeted for fall 2026.** Reliable reporting from Bloomberg’s Mark Gurman and supply-chain sources indicates the book-style device—featuring an approximately 5.5-inch cover display that unfolds to a roughly 7.8-inch inner panel with a wide aspect ratio—is in late-stage validation, with the hinge now the primary focus after display and other components advanced. Earlier production concerns (yields, hinge durability, and mass-production timing shifting from June toward August) have been addressed without derailing the fall window, though initial supply may be constrained, similar to past complex launches like the iPhone X. Apple has already greenlit a second-generation model for 2027 (codenamed V78), signaling commitment to foldables as a permanent high-end tier rather than a one-off experiment. This follows years of monitoring Samsung and Google foldables while reallocating resources (including delaying a foldable iPad) to meet the 2026 target. The device is expected to carry a starting price above $2,000 and integrate iOS 27 features like enhanced multitasking. For a prediction market on release timing, the primary near-term catalyst is the imminent September event; consistent on-track signals from multiple credible outlets have driven strong trader consensus toward a 2026 outcome, tempered only by the possibility of very limited early availability or a staggered on-sale date into late 2026 or early 2027.
