Apple CEO John Ternus says the company cannot yet predict when supply of the iPhone Duo will meet demand. In an interview with Reuters, Ternus said Apple is "working hard to get it to as many customers as quickly as possible, but at this point, we're not able to predict when supply and demand will be in balance."

Apple launched its first foldable last month for $1,999, with a 5.4-inch outer display and a 7.6-inch inner screen. Preorders sold out quickly, and some shipments are expected to arrive in 2027. Apple also offered a limited number of models in stores at launch.

In the Reuters interview, Ternus also addressed reports of cracked screens. He said "a very small percentage" of iPhone Duos were returned for this issue and that Apple is replacing them.

Ternus linked the supply constraints to memory costs. On Apple's Q4 2026 earnings call on Monday, he said, "What we're seeing with memory pricing right now is unprecedented." He added that Apple expects "even higher memory costs" in the December quarter, which he said is "partly offset" by recent price increases. Apple has raised prices across its product lineup this year, including higher starting prices for the iPhone 18 Pro and Pro Max.

Apple reported record iPhone revenue of $57.58 billion for its fourth quarter, even without a standard iPhone 18 model.
