Apple Inc. NASDAQ:AAPL shares have climbed 4.7% since August 26, before next week’s product event supplies official prices. That advance leaves the launch with a fairly demanding setup.
An iPhone price shock is now part of it, after TrendForce said Thursday that iPhone 18 prices could rise 10% to 20%.
The research firm blamed dearer memory and estimated that 256-gigabyte Pro memory costs are nearly 400% higher than last year. Apple has confirmed none of those product details.
The market has not panicked over that estimate. Apple traded at $327.66 at 8:58 a.m. EDT Friday, down 0.2% from Thursday’s close.

The rally matters because expectations rose before Apple showed the phones or their prices. A small miss can now carry more weight than the same disappointment did in August.
There is an appealing piece of arithmetic here. A 10% price increase can offset a 9.1% fall in units. At 20%, the unit cushion reaches 16.7%.
Revenue might survive that trade, although profit per phone may not.
How much unit pressure can price absorb?
Maximum unit decline that leaves revenue unchanged, before mix, currency and costs.
Arithmetic scenario, not a forecast. Calculation: price increase ÷ (1 + price increase). Apple does not disclose enough per-device cost data to calculate a gross-margin breakeven.
These are revenue-neutral boundaries, not sales forecasts. Trade-ins, carrier subsidies and currency can change the price a customer actually feels. Pro-model mix will change the revenue result too.
TrendForce’s 400% estimate applies to memory, not the whole phone. It said savings on other components would probably fall short of that increase. Apple may absorb part of the bill to protect market share.
The reported release schedule adds a wrinkle. TrendForce expects the fall range to focus on Pro models and a tentative foldable. It puts the standard iPhone 18 and other variants in early 2027.
That timing could reduce fall units without proving that buyers rejected the prices. It could also lift average selling prices by concentrating sales in costlier models. Quarterly comparisons would need careful reading.
Apple’s accounts draw the boundary more clearly. Product gross margin was 40.1% in the June quarter. Services earned 75.6%.
That difference matters because price does two jobs. It must cover added hardware cost without driving away too many buyers. Those buyers also feed the services base.
Chief Executive Tim Cook called it Apple’s “strongest June quarter ever.” He cited double-digit growth across iPhone, Mac and Services. The 50.1% company margin included roughly two percentage points from tariff refunds.
The iPhone still carries the quarter

The iPhone generated 49.6% of Apple’s $109.42 billion quarterly revenue. Its sales rose 22% from a year earlier. A poor launch would reach far beyond one product line.
Services supplied $30.74 billion in the same quarter. Chief Financial Officer Kevan Parekh said the active-device base reached another record. That base gives Apple time, though it cannot make weak hardware demand irrelevant.
A higher price can also stretch replacement cycles. That effect arrives slowly, then appears in unit comparisons long after launch-week queues disappear. The installed base softens the damage but does not erase it.
Last September offers a useful check. Apple added $100 to the iPhone 17 Pro’s starting price, while base and Pro Max prices held steady.
The shares fell 1.5% that day. One price increase did not settle the argument about demand.
Nor will a foldable settle it this year. TrendForce estimated a $2,099 to $2,299 starting price and limited initial supply. It expects foldables to remain about 2% of the global smartphone market in 2026.
Every specific device claim remains an outside estimate. Apple has announced the event date, not an iPhone 18 lineup. A different launch mix would change both the volume math and its timing.
Apple’s event begins Wednesday at 10 a.m. PT. Official prices come first. Delivery times and Pro-model mix will provide the cleaner demand read afterward.
