TSMC is sitting on $1 billion worth of finished iPhone chips with nowhere to go
Ripple effect: In the run-up to the launch of the foldable iPhone Ultra, iPhone 18, and iPhone 18 Pro, Apple and its assemblers are working to secure enough mobile DRAM.

Ripple effect: While critics and PC enthusiasts are cheering for the AI bubble to burst, Big Tech and enterprise ventures cannot buy AI accelerators fast enough. In fact, even one of the world's most important chip manufacturers is now facing significant issues with its ability to meet customer demand.
