The launch of the iPhone 18 is facing immediate headwinds as a persistent global shortage of RAM chips restricts production volumes.
The scarcity stems from the highly specialized and rigid manufacturing conditions required for these memory components, which prevent suppliers from rapidly scaling output to meet surging demand.
This supply constraint arrives at a critical juncture for Apple, which recently confirmed price increases across its MacBook and iPad lines.
Those hikes were a direct response to elevated costs driven by the same memory chip deficit, fueled largely by insatiable demand from artificial intelligence infrastructure buildouts.
The inability to secure sufficient RAM for the iPhone 18 suggests that cost pressures are now translating into tangible inventory risks for the company's most important revenue driver.
The broader semiconductor market remains tight, with memory manufacturers prioritizing high-margin AI-related contracts over consumer electronics.
