The decision Apple faces before its September hardware event has rarely been starker. A supply chain analysis released Monday projects that the iPhone 18 Pro will cost the company 38 to 40 percent more to manufacture than the iPhone 17 Pro, a component cost surge the same size as the one that drove Mac and iPad prices higher in June. Whether Apple absorbs it or passes it to iPhone buyers is the question six weeks of silence has left open.
Market research firm TrendForce released the estimate Monday, with the figure circulating across technology publications including 9to5Mac, AppleInsider, and MacRumors. The primary driver is memory. Wccftech, reporting on TrendForce’s analysis, cited an estimate that DRAM components alone account for roughly 42 percent of the iPhone 18 Pro’s total bill of materials. Tech Times, also citing the research, reported that the 1TB model sees memory reaching a record 34 percent of build cost, a figure the publication linked to the specific demands of high-density flash configurations and their effect on component allocation.
What produced those numbers is not a mystery. Over the past eighteen months, AI data centers have absorbed a disproportionate share of global DRAM production. SK Hynix and Samsung, two of Apple’s primary memory suppliers, have been redirecting manufacturing capacity toward server-grade and high-bandwidth memory orders from cloud infrastructure builders, customers who pay significantly more per chip and commit to far larger volumes than a smartphone manufacturer. Standard DRAM, the kind that goes into iPhones, has become a contested resource even for a buyer of Apple’s scale. TrendForce’s own prior research pegged DRAM price increases at 98 percent in the first quarter of 2026 alone, with further increases through the summer.
Apple and Microsoft raised prices on Macs, iPads, and Xbox consoles in June, citing the same AI-driven DRAM shortage the TrendForce analysis now links to the iPhone 18 Pro’s elevated build cost. MacBook Air prices rose by $200 that month. Some MacBook Pro configurations increased by $500. Apple’s public explanation was direct: memory costs had become unsustainable to absorb. iPhone prices were left unchanged in June. Whether that exemption holds in September is the question TrendForce’s estimate puts back on the table.
On July 31, Tim Cook warned analysts that rising memory costs would continue into the fourth quarter, framing the pressure as a sustained structural dynamic rather than a temporary squeeze. Apple shares dropped 8 percent on the guidance, even as the company reported $109.4 billion in quarterly revenue and record iPhone sales. Analysts interpreted the sell-off as investors pricing in the risk that Apple would either absorb significant margin compression or pass costs to consumers in September, neither scenario being straightforwardly positive.
The same memory constraint that reached the Mac lineup has since spread to Apple’s most popular laptop. MacBook Air went on backorder in early August, with delivery times pushed into late August and September, the first time the product has carried multi-week wait times during the back-to-school season. The pattern of shortage moving from one product category to the next has now reached TrendForce’s most direct projection: a manufacturing cost increase for the device that accounts for roughly half of Apple’s annual revenue.
The 1TB configuration warrants its own attention in TrendForce’s framing. Tech Times’ reporting flagged that the highest-capacity iPhone 18 Pro variant will cost more to build and may deliver slower performance, a pairing that reflects a documented engineering trade-off. High-density NAND flash storage, compressed into the physical and power constraints of a flagship smartphone chassis, can involve bandwidth limitations that lower-capacity variants sidestep. If the performance trade-off is confirmed after launch, it would be the first instance of an iPhone Pro model carrying a documented speed disadvantage at its highest storage tier relative to the base configuration.
TrendForce constructs its bill-of-materials models from disclosed component pricing, supplier procurement patterns, and supply chain contacts rather than confirmed Apple purchase agreements. The firm’s BOM estimates have historically tracked within a few percentage points of teardown analyses conducted by independent researchers in the weeks following launch, lending them credibility with semiconductor analysts and institutional investors. What the estimates cannot account for is the pricing Apple locked in through long-term supply agreements negotiated earlier in the year. Whether those agreements provide meaningful insulation from the spot market increases TrendForce’s data reflects is not publicly known.
Apple will not confirm iPhone 18 pricing until the event itself. The decision, whether to absorb the manufacturing cost increase, pass it to consumers, or split the difference across storage tiers, carries implications beyond a single product cycle. iPhone is not a product Apple can reprice sharply without affecting the upgrade cadence that sustains its services revenue and installed base growth. Whether the starting price that has anchored the iPhone Pro for several generations survives a manufacturing environment this different from the one in which it was set is, as of Monday, still unresolved.
