Apple's first foldable iPhone remains on track for a September 2026 debut alongside the iPhone 18 Pro models, according to multiple supply chain reports and Bloomberg sourcing, driving the strong market-implied odds for a pre-2027 release. Recent developments include production ramp-up for up to 10 million units, iOS 27 software references to folding hardware and iPad-like multitasking layouts, and Apple's shift toward a split launch cycle that prioritizes premium devices in fall 2026. While some Nikkei reporting flagged engineering snags and possible limited early shipments, credible updates indicate these are manageable, with the device positioned as a high-end "Ultra" model exceeding $2,000. Traders are pricing in the timeline based on consistent analyst confirmations from Ming-Chi Kuo and others, though any last-minute production issues could still shift outcomes before the expected announcement window.
