IDC forecasts $27bn from Apple's first foldable in a category whose shipments are falling

Divide IDC's two headline numbers into each other and they do not quite meet: $27bn across 10 million units is $2,700 a phone ^[1], against the $2,500 average price the forecast says it was built on ^[7], an 8 per cent gap ^[7], and at $2,500 the revenue needs 10.8 million units ^[2]. That is not unusual in a first-year estimate for a device nobody has bought yet. The price is the assumption doing the work, and the unit count is what gets solved for.

Run the value share backwards and the pool becomes legible. If $27bn is 44 per cent of segment value ^[6], the whole premium foldable pool is about $61bn ^[3], leaving roughly $34bn ^[4] for the incumbents that IDC's Francisco Jeronimo says will not surrender volume ^[9]. Huawei took 50 per cent of foldable units and 55 per cent of value in the second quarter of 2026 ^[5], so its average foldable already clears the segment average by about a tenth ^[5], and by Jeronimo's count its head start in Chinese hardware, retail and carrier relationships runs five years ^[10].

Then there is the ratio that actually defines the bet. The $2,500 assumption is double Apple's current iPhone average selling price, which places that average near $1,250 ^[8][6], so the ask is one device sold at twice the house price into a category that shrank 15 per cent year on year in the first half of 2026 ^[4] and still accounts for roughly 2 per cent of devices sold ^[3]. Jeronimo's argument is that Apple does not need the most foldables, because anchoring the premium tier and doubling its own average selling price converts a stalling, volume-led category into a value engine and forces rivals to compete on Apple's economics ^[11]. He names the price that limits the addressable base as one of the genuine risks in the same breath ^[10]. That is the honest tension: the number that makes the revenue work is the number that caps the units.

Apple did not ship a base model to get here. The keynote carried the 18 Pro and 18 Pro Max with no base model, which The Indian Express reads as a sign that annual updates across every product vertical have become hard ^[2]. Ternus's stated logic for the hinge is that the intelligent personal hub needs more screen space ^[12], and the on-device AI claim rests on the A20 Pro's second neural engine, per silicon engineering vice-president Sribalan Santhanam ^[13].

The reading this desk holds is that Apple is buying average selling price rather than share, and that the 10 million units matter less than whether the realised price holds. Three things could undo it. Trim the price to widen the base, and the value engine becomes a mid-volume product with a hinge. Let the first generation disappoint on crease, weight or durability, the risk Jeronimo lists first ^[10], and the units do not arrive at any price. Leave China to Huawei, and Apple's 44 per cent of value comes out of everyone else's markets. That is an arithmetic finding, not a sentiment one: below $2,500 realised, the $27bn requires more than 10.8 million units ^[2], and a category shrinking 15 per cent ^[4] has not shown it has them.
