Apple Shares Fall 4% as AI Chip Demand Drives Up iPhone Production Costs
Apple shares fell 4% after warning of rising memory chip costs, pressuring profit margins. CEO John Ternus expects further cost increases, with gross margin falling to 47.9% in Q3 and projected to decline further. The company is managing costs by securing supplies and raising prices, but faces challenges from high demand for AI-related chips. Apple's market valuation could drop by over $170 billion if losses hold.
How this was made

The 30-second read
Why it matters
The key tradable takeaway is forward gross-margin pressure from higher memory costs plus incremental AI-related spending, with potential knock-on effects to device pricing tolerance among consumers.
Market read
Apple’s margin guidance and memory-cost outlook are likely to drive near-term repricing of profitability expectations and raise sensitivity to any further semiconductor pricing moves.
What to watch
The article notes increased manufacturing purchase obligations and supply securing, which may mitigate cost volatility even if spot memory prices keep rising.
Background
Apple’s first quarterly results under CEO John Ternus included a warning that memory pricing is unprecedented and expected to rise further, alongside AI upgrade costs.
Ticker impact
Apple warned that high memory chip prices will keep pressuring margins, with December-quarter gross margin guidance down to 45%-46%.
Likely downside pressure as the market prices in further gross-margin deterioration and higher iPhone/Mac production costs.
The article cites Apple’s explicit margin outlook for the December quarter and CEO commentary that memory costs are expected to rise further.
Market effects
Highlights how AI-driven HBM demand can spill over into DRAM pricing, pressuring consumer electronics gross margins broadly.
US large-cap tech weakness weighed on the S&P 500 and Nasdaq as Apple fell about 4%.
Reinforces global semiconductor supply-demand imbalance between AI memory (HBM) and conventional DRAM used in consumer devices.
Counterpoint
Apple’s strong premium iPhone demand and use of previously purchased lower-cost memory could cushion the margin hit more than the market fears.
