AI Wants “Every Scrap of RAM.” Qualcomm and Arm Just Showed Who Pays the Bill
Qualcomm (QCOM) and Arm Holdings (ARM) shares fell 9.5% and 13% respectively due to rising memory costs impacting their phone businesses. Qualcomm's gross margin declined to 50.8% from 55.3% a year earlier, with price increases not expected to offset costs until late 2027. Arm's royalties were affected by memory pricing, though data center growth provided some support. Micron Technology (MU) also saw a 17% drop but benefits from higher memory demand.

Why it matters
Both Qualcomm and Arm experienced double‑digit intraday declines after issuing weaker guidance tied to memory cost pressures.
Market read
Guidance cuts and royalty pressure from memory costs create immediate downside risk for key semiconductor stocks.
What to watch
Arm’s data‑center royalty growth and Qualcomm’s automotive revenue expansion may offset phone‑segment weakness.
Background
The article discusses how rising AI‑driven RAM demand is inflating memory costs, hurting phone‑chip makers Qualcomm and Arm, while benefitting memory supplier Micron.
Ticker impact
Qualcomm guided December-quarter non‑GAAP EPS to $2.15‑$2.35, well below expectations, triggering a 9.5% drop.
downward pressure as investors price in lower earnings and slower margin recovery
The guidance is a fresh, material downgrade; the stock fell 9.5% on the news, indicating immediate sell pressure.

The article provides the first report of Arm’s guidance impact, prompting a sharp price drop.
Market effects
AI‑driven memory shortage pressures phone‑chip designers and could reshape margins across the semiconductor sector.
U.S. chip and memory makers face heightened cost pressures, affecting domestic equity performance.
Worldwide AI demand for RAM amplifies supply constraints, influencing global semiconductor valuations.
Counterpoint
If new memory supply arrives quickly, pricing could fall, easing margin pressure and supporting a rebound.
