Apple's new foldable iPhone Duo, priced from $1,999, is experiencing robust early demand, with launch-day pickup inventory selling out and online delivery estimates extending into late January. Analysts believe the device, which establishes a new price point above the Pro and Pro Max, could significantly boost iPhone's average selling price and revenue by attracting high-spending customers. Counterpoint Research anticipates initial demand will outstrip supply, while JPMorgan expects the Duo to have a disproportionate impact on iPhone revenue, even if overall shipments remain flat next year.
