The launch serves as the centerpiece of a broader hardware refresh that includes the iPhone 18 Pro, updated AirPods, and the Apple Watch Series 12.
This release represents a significant strategic shift for the company as it seeks to restore its reputation for innovation in a maturing smartphone market.
By entering the foldable category, Apple is positioning the Duo as a high-end status symbol to compete with existing folding devices from rivals like Huawei and Samsung.
The high-stakes event also marks a transition in leadership, serving as the first major product slate introduced under new CEO John Ternus.
The iPhone Duo is the result of a development process that Bloomberg reports was a decade in the making.
Beyond the foldable flagship, the updated Apple Watch is expected to feature a new recording capability, though specific technical mechanisms for the feature were not disclosed.
These products are scheduled to be unveiled on Wednesday morning, signaling Apple's intent to capture growth through a combination of high-margin hardware and new artificial intelligence integrations.
