Apple’s first foldable, the iPhone Duo, is projected to reach roughly six million units sold by the end of 2026, according to analysts. Despite the device not yet being commercially available, forecasts from Counterpoint Research suggest that production limitations could cap its initial sales.
Production Challenges Temper Initial Numbers
Analyst Ivan Lam notes that achieving this six-million mark depends heavily on how quickly Apple can scale up manufacturing. Early reports have flagged yield issues at Foxconn, with successful assembly reportedly just over 60 percent. These figures fall short of Apple’s typical quality thresholds, implying it may take six to twelve more months of refinement before production operates at full capacity.
Why Six Million Looks Small—Until You Put It in Context
Relative to Apple’s total output, six million units across the final stretch of 2026 is modest. Between the fourth quarter of 2026 and the first quarter of 2027, Apple is expected to produce about 80 million iPhones—including the Duo alongside the iPhone 18 Pro, Pro Max, and standard models. The Duo’s six-million forecast covers just a few months, making it a small slice of the full lineup.
Yet for a first-generation foldable phone from Apple, analysts see this as a reasonable start. It mirrors what other foldables in the market have managed in their early phases. In fact, owning a foldable offering could boost interest across Apple’s mainstream iPhones as well—simply having the Duo in the lineup may raise the profile of the whole family.
While initial sales volume won’t move the needle as much as Apple’s core models, the Duo’s launch is expected to play a strategic role: establishing brand presence in foldables, learning from manufacturing kinks, and signaling to consumers that Apple is entering a new category with long-term commitment.
The public’s appetite for foldable phones is gradually growing. If Apple can resolve early production inefficiencies quickly and get supply in line with demand, the Duo could pave the way for versions with higher volumes in 2027 and beyond.
Because of this, the six-million-unit estimate isn’t an underperformance—it’s a realistic outcome for a bold first step. Watch closely for updates on yield improvements, pricing, and how the Duo stacks up in performance and usability versus established foldables.
