Driven by soaring memory prices, TrendForce estimated on August 10 that the bill of materials for the 256GB iPhone 18 Pro will run approximately 38 percent above its 2025 predecessor, with memory's share of total component cost rising from roughly 10 percent a year ago to approximately 34 percent in the third quarter of 2026. Memory has now overtaken the application processor and the display panel as the single largest cost component, a reversal from prior iPhone generations. TrendForce projects that share will rise past 40 percent in the first half of 2027, at which point the panel and application processor will have been compressed to single-digit percentages of overall cost.
The proximate cause is a structural reallocation of global chip production. The needs of AI infrastructure now dictate component availability for the entire technology ecosystem, a stark departure from the consumer-led dynamics of the previous decade. Micron Technology has sold out its entire HBM supply for 2026, confirming that the most profitable production lines are unavailable to the consumer sector. The production of a single HBM wafer displaces two or more conventional DRAM wafers due to larger die sizes and greater complexity, creating a net reduction in the global supply of memory bits even as wafer output remains constant. Gartner expects memory prices to climb roughly 130 percent by the end of 2026, and the price inversion is already striking: legacy DDR4 has become more expensive per gigabit than cutting-edge HBM3e, a situation with no recent precedent.
TrendForce states that higher retail prices for the iPhone 18 Pro are unavoidable, but adds that Apple may offset some of those costs by reducing gross margins to prevent weakening consumer demand, aiming to keep prices manageable and maintain shipment volumes. TrendForce believes Apple is likely to follow the pricing strategy adopted for its recent MacBook launches by sacrificing part of its gross margin to soften price increases for the iPhone 18 lineup. Apple had already raised prices across the Mac, iPad, Apple TV, HomePod, and Vision Pro lines in June over concerns about the same memory crunch; the iPhone lineup escaped that round, but it looks increasingly unlikely to escape the next one.
The broader market damage is more severe where margins were already thin. Pressures will be particularly acute in entry-level and mid-range segments, where already-thin margins leave little room to absorb higher costs; with memory prices having risen five to sevenfold since the beginning of 2025, many brands may have no choice but to implement substantial price increases or discontinue product lines that have slipped into negative gross margins, and TrendForce expects global smartphone production to remain under downward pressure from the second half of 2026 through 2027. IDC now expects the memory shortage to wipe 12.9 percent off global handset shipments in 2026, taking the market to 1.12 billion units, roughly 160 million fewer smartphones year on year, and dragging volumes to their lowest annual level in more than a decade. IDC senior research director Nabila Popal called it "a structural reset of the entire market" and warned that the sub-100-dollar smartphone segment, representing 171 million devices, will become "permanently uneconomical" even after memory prices stabilize. Skeptics note that TrendForce's figures cover only bill-of-materials costs and exclude assembly, software, and overhead, meaning the 38 percent component increase does not translate one-for-one to retail prices; TrendForce itself acknowledges these are supply-chain cost estimates and projections, not confirmed pricing from Apple, with final retail figures expected around September 2026.
If you were waiting for proof that building AI data centers changes the price of the phone in your pocket, you now have it.
