Apple's first foldable iPhone could add roughly $14 billion to December-quarter revenue, Morgan Stanley analyst Erik Woodring estimated ahead of the company's Sept. 9 product launch event.

Key Points:

• Morgan Stanley pegs the foldable iPhone's December-quarter contribution at about $14 billion, with 7 million to 8 million units built in the second half of 2026.

• Rising memory costs are expected to lift Pro models more than $200 year over year, the broadest like-for-like iPhone price increase the company has attempted.

• The Sept. 9 keynote is the first major launch under new chief executive John Ternus.
