Apple’s official August 26 announcement of the September 9 “Surprise and Shine” event has driven the 95.5% market-implied odds for a foldable iPhone reveal. Consistent supply-chain reports, analyst confirmations from Mark Gurman and others, and Apple’s invitation all point to the long-rumored book-style device—expected to feature a roughly 5.5-inch cover display and 7.8-inch inner screen—appearing alongside the iPhone 18 Pro models. The event marks the first major launch under incoming CEO John Ternus and follows years of development focused on hinge durability, crease reduction, and titanium construction. While the announcement itself appears locked in, traders note that any last-minute production snag or shift in software features could still alter the precise reveal, though such outcomes remain unlikely this close to the date.
