Apple’s first foldable iPhone may be even harder to buy at launch than the already tight supply estimates suggested. A report published by 9to5Mac on September 15 points to a fresh analyst assessment indicating the iPhone Duo could be in even shorter supply than expected when pre-orders open on October 16, with the device going on sale October 23.
The baseline numbers come from supply chain analyst Ming-Chi Kuo, who wrote in July that assembly shipments for the foldable iPhone in the second half of 2026 would total roughly 7 to 8 million units, with third-quarter shipments of just 0.5 to 1 million units, about 10 percent of the total. By comparison, Kuo estimated third-quarter shipments of the iPhone 18 Pro and Pro Max at 20 to 22 million units. A September 1 supply chain report attributed the slow ramp to Apple’s quality control standards on the new hinge and display lamination process.
Kuo predicted delivery times could stretch to four to six weeks or longer, and that it would be hard to get a unit until at least December. He also expected scalpers to resell the phone at a 50 to 100 percent premium over its $1,999 list price, which sits $100 above Samsung’s Galaxy Z Fold 8 and $100 below the Z Fold 8 Ultra.
What Apple is actually selling
The iPhone Duo opened to a 7.6-inch inner display, the largest ever on an iPhone, with a 5.4-inch outer screen and a passport-like 1:1.4 aspect ratio when both open and closed. Apple’s design brief was pointed: CEO John Ternus said other companies had created a foldable that feels like two phones awkwardly stuck together, and that the Duo would redesign the foldable experience. The phone uses the same A20 Pro chip as the iPhone 18 Pro, supports Apple Pencil on both screens, has an under-display selfie camera and carries an IP68 rating. Apple claims 31 hours of video playback on the inner display and about 24 hours of mixed use.
The price split is unusual for Apple. The Pro models start at $1,199 and $1,299, and the base iPhone 18 was not announced at all at the September 9 event. It is expected in early 2027, part of a shift to a split fall and spring release cycle that analysts link to the memory chip shortage driving component costs up across the industry. Apple raised prices 15 to 33 percent across Mac, iPad and home device lines earlier this year, which former CEO Tim Cook called a 100-year-flood event in July, and the company issued a disappointing fiscal fourth quarter revenue forecast at the same time, citing supply constraints.
| Model | Start price | Pre-order | On sale |
|---|---|---|---|
| iPhone 18 Pro | $1,199 | Sept 12 | Sept 18 |
| iPhone 18 Pro Max | $1,299 | Sept 12 | Sept 18 |
| iPhone Duo | $1,999 | Oct 16 | Oct 23 |
The launch-week math
If Kuo’s third-quarter estimate holds, only up to 1 million Duo units will exist when pre-orders open in mid-October. Apple’s own track record offers a precedent: the iPhone X in 2017 shipped in similarly constrained volumes after a delayed start, and resale premiums ran for months. The difference this time is that the foldable market itself has matured. Samsung has shipped foldables since 2019, and its Z Fold 8 went to a wider, shorter chassis that the Duo now echoes, a sign the category’s design questions have mostly been settled by someone other than Apple. The Duo is eSIM-only worldwide, like the iPhone Air, which limits carrier flexibility in markets where physical SIMs remain common.
Foldables still account for a small fraction of global smartphone sales, roughly 2 percent by most estimates, but the premium segment is where margins live. Analysts cited by Fortune noted that the split launch could support average selling prices, while creating a risk that price-sensitive consumers defer upgrades until cheaper models arrive in the spring. The seven-year gap between the first Galaxy Fold and Apple’s entry also gives Apple an advantage the original foldable makers never had: hinge reliability, crease visibility and app optimization are now solved problems, and Apple’s suppliers have had years to build yield.
The September 9 event was Ternus’s first as CEO after taking over from Tim Cook on September 1, and the Duo was its centerpiece. Michael Gartenberg, an analyst and former Apple marketing employee, told Fortune that Apple events had become a wash, rinse and repeat cycle, but that this one was a good event for Apple and a good start for the new CEO. Reviewers flagged the crease as the claim to watch: it is still visible, though Apple says its multi-layer lamination process will keep it from developing further over time. Ars Technica noted that Apple included features Samsung introduced and then dropped, such as the under-display camera and Pencil support, a sign Apple is betting users want the fuller feature set even at higher weight and cost.
For buyers, the practical guidance is unchanged from what Kuo wrote in July: pre-order early or expect to wait, and budget for the possibility that resale premiums make waiting the more expensive option. For Apple, the question is whether the supply ramp accelerates fast enough to meet a first-holiday-season demand curve that no foldable maker has faced before, backed by an installed base of more than a billion iPhone users. Kuo expects launch buzz and supply constraints to fade by the first quarter of 2027, by which point the base iPhone 18 will have arrived and the real test of foldable demand can begin.
