iPhone Duo Faces Potential Launch Stock Shortage as Apple Cuts Production Forecast

Apple’s highly anticipated first foldable iPhone, the iPhone Duo, could face limited availability when it officially goes on sale. With pre-orders approaching, new industry estimates suggest that Apple may not be able to produce as many units as previously expected.

The iPhone Duo is also set to follow a different launch schedule from Apple’s conventional iPhone lineup. While the iPhone 18 Pro and iPhone 18 Pro Max are expected to arrive during the traditional September launch period, the foldable model is reportedly scheduled for a later release.

Pre-orders for the iPhone Duo are expected to begin on October 16, with the first deliveries reportedly scheduled for October 23. However, concerns over production capacity are now emerging ahead of the launch.

Hinge production reportedly creates a bottleneck

Rumors about limited supplies of Apple’s first foldable iPhone had already surfaced before its official release. A new assessment from analyst Jeff Pu appears to reinforce those expectations.

According to a research note seen by 9to5Mac, Pu now expects Apple to ship approximately 6 million iPhone Duo units in 2026. His previous forecast had stood at around 7 million units, meaning the latest estimate represents a significant downward revision.

Importantly, the reduction is reportedly not linked to weaker demand expectations. Instead, production constraints surrounding the device’s hinge mechanism are being cited as the main reason.

The hinge is one of the most technically demanding components of a foldable smartphone. It must allow the device to open and close repeatedly while maintaining structural strength, display alignment and long-term durability. Any disruption in hinge manufacturing can therefore have a direct impact on the total number of devices Apple is able to assemble.

For a first-generation foldable product, such manufacturing challenges are not particularly unusual. Apple is entering a category that requires specialized components and highly precise production processes, meaning scaling up manufacturing could take time.

A huge production gap compared with the iPhone 18 Pro

Jeff Pu’s estimates also highlight just how different the production scale of the iPhone Duo could be compared with Apple’s conventional flagship models.

Pu expects Apple to ship approximately 72 million iPhone 18 Pro and iPhone 18 Pro Max units by the end of 2026. By comparison, the forecast for the iPhone Duo stands at only 6 million units.

That means Apple could ship roughly 12 times as many Pro models as foldable Duo units during the same period.

The difference illustrates the likely position of the first foldable iPhone within Apple’s broader product strategy. Rather than immediately becoming a mass-market alternative to the standard iPhone, the Duo could initially remain a relatively specialized and limited-volume product.

That would also give Apple additional time to refine its manufacturing processes, strengthen its supply chain and increase production capacity for key components such as the hinge and foldable display.

A $1,999 price tag adds another layer

Production limitations are not the only factor that could keep the iPhone Duo away from the mainstream. Its expected price is also likely to play a major role.

The first foldable iPhone is expected to start at around $1,999, potentially making it the most expensive iPhone ever launched at its entry price.

A premium price combined with restricted production capacity could position the Duo as a niche product during its first generation. Apple may therefore initially be targeting consumers willing to pay a substantial premium for a new form factor rather than attempting to make the foldable iPhone an immediate replacement for its mainstream models.

Limited supply could also make the launch particularly challenging if demand exceeds Apple’s initial production capacity. Customers hoping to purchase the device at launch could potentially face longer waiting periods if stock sells out quickly.

Apple’s first foldable could start small

Apple has yet to publicly confirm its actual production targets, and Jeff Pu’s 6-million-unit figure remains an analyst estimate rather than an official Apple forecast.

Nevertheless, if the reported hinge-related manufacturing constraints are accurate, the iPhone Duo could enter the market with a very different profile from the company’s traditional iPhone launches.

Instead of focusing immediately on enormous sales volumes, Apple may initially use the Duo as a high-end showcase for its foldable technology and ecosystem.

The combination of a $1,999 starting price, limited production and the technical challenges associated with a first-generation foldable device could make availability one of the biggest stories surrounding the iPhone Duo when pre-orders begin.

For Apple, the next challenge will be turning a technically ambitious first-generation product into a foldable platform that can eventually be produced at a much larger scale.
