iPhone Duo Sales Forecast Explodes—and Android Foldables Could Take a 20% Hit

Specifications, U.S. pricing and release timing are based on Apple’s launch information and reporting available as of September 12, 2026.

Why Did iPhone Duo Sales Expectations Jump So Quickly?

The iPhone Duo did something many earlier foldable phones could not: it made the category feel relevant to millions of existing iPhone users overnight.

Apple entered late, but it arrived with a recognizable iPhone interface, a 7.6-inch inner display, an A20 Pro chip and a $1,999 starting price that was lower than some pre-launch predictions.

That combination changed the conversation from “Would Apple ever make a foldable?” to “Should I preorder the iPhone Duo instead of an iPhone 18 Pro Max?”

According to reports discussing Goldman Sachs’ outlook, the firm maintained a 2026 base-case shipment estimate of 14 million units and a bullish scenario of up to 35 million.

That is an unusually wide range. It shows that analysts agree on the iPhone Duo’s potential but disagree sharply over how quickly Apple can manufacture enough units and convert interest into actual purchases.

Are Other Foldable Phone Sales Really Being Crushed?

Not yet in the literal sense. The iPhone Duo has only been announced, and retail availability does not begin until October 23.

However, the shipment outlook for Android foldables already looks much weaker once Apple enters the calculation.

TrendForce forecasts approximately 20.2 million global foldable smartphone shipments in 2026. Apple could contribute about 5 million of those units, while combined shipments from Android brands may reach only 15.2 million—more than 20% lower year over year.

The iPhone Duo nevertheless creates an immediate competitive problem: buyers considering a $1,700 to $2,000 Android foldable now have an Apple alternative at almost the same price.

iPhone Duo Could Capture Nearly 25% of the Market in Months

TrendForce estimates that 5 million iPhone Duo shipments would give Apple a 24.8% foldable smartphone market share in 2026.

That would be remarkable because the Duo will be available for only part of the year. Apple would be entering a mature category and potentially taking around one-quarter of it within its first launch window.

Samsung is still forecast to lead with approximately 7.1 million foldable shipments and a 35.1% share. Huawei could remain around 5 million units, matching Apple’s estimated volume.

Figures above reflect TrendForce forecasts rather than finalized retail sales.

Why the Galaxy Z Fold 8 Is Under the Most Pressure

The Galaxy Z Fold 8 is not a failed product. Early reports suggest Samsung’s 2026 foldable lineup started strongly and improved on the previous generation.

The danger begins when shoppers compare the Galaxy Z Fold 8 and iPhone Duo at similar premium prices.

Before Apple entered the category, Samsung was the default global choice for a book-style foldable. Now iPhone users no longer need to leave iMessage, AirDrop, Apple Watch, iCloud or the wider Apple ecosystem to get a folding phone.

That is more damaging than a simple specifications comparison. Apple is not only competing for existing foldable users—it is bringing a much larger installed base into the market.

Huawei Faces a Different iPhone Duo Threat

Huawei remains extremely powerful in China’s foldable phone market. Reuters cited an IDC analyst who estimated that Huawei controls nearly 80% of that regional segment.

The iPhone Duo will not erase that advantage overnight. Huawei benefits from local brand strength, established foldable hardware and a wider selection of models.

However, Apple now offers Chinese premium buyers something they previously could not buy: a real foldable iPhone with an iPad-like inner-screen experience.

Even a modest shift among high-income buyers could affect the most profitable part of Huawei’s foldable business.

Apple’s Biggest Advantage Is Not the Hinge

The nearly invisible crease, titanium construction and custom hinge help the iPhone Duo make a strong first impression. But hardware alone does not explain the aggressive sales forecasts.

Apple’s larger advantage is confidence.

Millions of customers already understand iOS, trust Apple’s retail support and own accessories or services connected to the iPhone ecosystem. For them, the Duo feels less like an experimental foldable and more like a new type of iPhone.

Apple also designed iOS 27 experiences around the larger display, including multiple app windows and layouts that change as the device opens or folds.

This software-hardware integration is the part Samsung, Google, Huawei and other rivals cannot quickly reproduce.

Supply May Matter More Than Demand

The gap between the 5 million, 14 million and 35 million forecasts may ultimately come down to production capacity.

A foldable phone requires more complex displays, hinges and assembly processes than a conventional iPhone. If Apple can build only a limited number of units, strong demand will not immediately translate into tens of millions of shipments.

This is why claims that Apple will “sell every iPhone Duo it can make” matter. Early sellouts could reflect both genuine demand and tight supply.

The real signal will be whether delivery estimates remain extended after the first launch wave—and whether Apple can expand production through 2027.

Could iPhone Duo Become the Best-Selling Foldable Phone?

It could, but perhaps not immediately.

Samsung has a full-year sales advantage, broader availability and several folding models. Huawei also has a dominant position in China.

Apple’s path becomes more interesting in 2027. IDC expects Apple could secure around 40% of the foldable phone segment by the end of that year.

If supply improves and the iPhone Duo generates a normal Apple upgrade cycle, it could become the single most important foldable phone even before it becomes the volume leader.

Should You Preorder the iPhone Duo?

The sales forecast should not decide whether you spend $1,999 or more.

The Duo makes the most sense for someone who wants an iPhone and iPad-like canvas in one device, regularly multitasks, watches video on a phone or wants Apple’s first genuinely new iPhone form factor in years.

The iPhone 18 Pro Max remains the safer option for buyers who prioritize camera flexibility, conventional case protection, longer-established durability and a lower starting price.

First-generation hardware also carries unknowns. Long-term crease visibility, inner-screen durability, hinge wear, repair prices and real-world battery life will become clearer only after customers use the phone for several months.

What the Forecast Really Means for the Foldable Phone Market

The iPhone Duo does not need to sell 35 million units to reshape foldable phones.

Even the conservative 5 million estimate could give Apple nearly one-quarter of the category in only a few months. A 14 million result would radically change vendor rankings, while 35 million would push foldables far closer to the mainstream.

For Samsung and Huawei, the immediate threat is not that their foldable phones suddenly became bad. It is that Apple has changed what premium buyers use as their reference point.

Every new foldable will now be judged against the iPhone Duo’s price, crease, software, ecosystem and retail experience.

Apple arrived late. It may still end up setting the rules.
