Apple has officially confirmed its September 9 “Surprise and Shine” event, with consistent reporting across supply chain sources and analysts indicating the long-rumored foldable iPhone—expected as the iPhone Ultra in a book-style design with roughly 5.5-inch outer and 7.8-inch inner displays—will be unveiled alongside iPhone 18 Pro models. Production has advanced to low-volume output despite earlier hinge and yield challenges, marking the first major hardware launch under incoming CEO John Ternus. This near-term catalyst, backed by developer hints in iOS 27 for dynamic app resizing on variable screens, underpins the 95.5% market-implied probability. Remaining uncertainty centers on any last-minute production setbacks or a decision to delay the actual reveal, though current timelines point strongly to an on-stage debut.
