Recent supply-chain reports and analyst updates have reinforced expectations for Apple's first foldable iPhone, likely called the iPhone Ultra or iPhone Fold, to launch in September 2026 alongside the iPhone 18 Pro models. Bloomberg's Mark Gurman and analyst Ming-Chi Kuo have affirmed the timeline remains on track for a book-style design with dual displays, following earlier production starts targeted for mid-to-late 2026. While April reports from Nikkei highlighted engineering hurdles around the hinge and display that could risk a 2027 shift, subsequent confirmations of limited initial supply and fall availability have sustained trader confidence. This positions the 82.5% implied probability for a pre-2027 release as a reflection of aggregated sentiment on Apple's ability to meet its internal schedule despite typical hardware development complexities.
