Apple has shifted its iPhone 18 lineup to a split release, launching only premium models—the iPhone 18 Pro, Pro Max, and foldable Duo—in September 2026 while delaying the base iPhone 18 to spring 2027. Component shortages in memory and advanced chips prompted the company to prioritize higher-margin devices, a strategy confirmed at the September event and by supply-chain partners. This extends the gap between standard models to roughly 18 months, the longest in recent history, and aligns the base version with other affordable options like the iPhone 18e. Traders are watching for confirmation of a February or March 2027 debut, which could be influenced by production ramps or further supply constraints.
