A new report from analyst Ming-Chi Kuo says that only certain models of the 2026 iPhone 18 range -- presumably the Pro editions -- will get 2nm processors.
TSMC is developing a 2nm process
It's previously been reported that Apple will not be able to use 2 nanometer processor technology until the iPhone 18 Pro in 2026, and now Kuo appears to have backed that up. His report does not actually specify the Pro series, saying only that not all of the iPhone 18 range will get it.
The processors for 2025 iPhone 17 models will be made by TSMC's N3P process/3-nanometer technology. The processor for 2026 iPhone 18 models is anticipated to use TSMC's 2-nanometer technology. However, due to cost concerns, not all new iPhone 18 models may be equipped with a

Given that the 2nm process will result in yet faster chips, it's surely a certainty that it will be in the Pro models. Theoretically, though, it could be limited to the iPhone 18 Pro Max.
TSMC has previously committed to launching its 2nm process in 2025, and some reports claimed it will be used in the iPhone 17 Pro. However, later reports said that mass production of the 2nm processor would come too late for the 2025 iPhone launch.
Also backing this up, Kuo further says that the 2025 iPhone 17 range will use TSMC's next generation of 3nm technology. Specifically, he claims the range will use the 2nm N3P design, which is claimed to offer a 5% performance increase over the current 2nm N3E design.
Again, Kuo does not specify which iPhone 17 models are to get processors using this technology. Previously, Apple made a clear distinction between the models by having the regular iPhones use the processors from the previous year's Pro models.
For 2024 and the iPhone 16 range, Apple instead developed two new processors. The iPhone 16 and iPhone 16 Plus got an A18 processor, while the iPhone 16 Pro models have an A18 Pro.
