A name that wasn't supposed to be there yet
In Apple's official documentation released at WWDC 2026, the list of devices compatible with Apple Intelligence and Siri AI explicitly includes Apple Watch Series 11, alongside Series 10, Ultra 2, and SE 3. The passage, reported by Engadget directly from Apple's communication, states features are available on "Apple Watch Series 10 or later, Apple Watch Ultra 2 or later, and Apple Watch SE 3 when paired with an Apple Intelligence-enabled iPhone nearby."
The phrase "or later" applied to Series 10 logically implies that Series 11 — not yet announced as a hardware product — is already planned and supported at the software level. Apple held no hardware event at WWDC, but inclusion in a software compatibility list is an established practice that anticipates an upcoming device announcement.
This is not an explicit hardware confirmation, but for those following Apple Watch's typical update cycle — usually in September — the data reinforces expectations of a Series 11 before year's end.
