Apple iPhone Duo is official: it could be hard to buy at launch

Apple unveiled the iPhone Duo on September 9. Pre-orders open October 16, deliveries start October 23, and the first batch already looks like it could be hard to get.

Analyst Jeff Pu has lowered his 2026 iPhone Duo shipment estimate to about 6 million units, down from 7 million. That change doesn’t seem tied to softer demand. The bigger problem appears to be supply: hinge bottlenecks, durability testing, inner-display flatness inspections, and reported production still stuck in the hundreds of units per day. Put that together and you could be looking at fast sellouts, longer shipping windows, and spotty store availability.

Apple’s book-style foldable starts at $1,999 for 256GB and climbs to $3,199 for 2TB. The iPhone Duo comes with a 5.4-inch outer screen, a 7.6-inch inner display, an A20 Pro chip, and a titanium frame, with Star White and Night Sky as the two color options.

Analysts still expect Apple to sell every unit it can make, grab 20% to 25% of the foldable market Samsung helped build, and give the wider iPhone upgrade cycle some momentum. Even so, the near-term upside may only go so far. Current forecasts put iPhone 18 Pro and Pro Max shipments at 72 million units, roughly 12 times higher.

If you want Apple’s first foldable, it’s probably smart to move quickly. Demand looks strong, supply looks unusually tight, and this launch could get picked over fast.

You can pre-order Apple’s iPhone Duo from Apple starting October 16.
