Apple scales back chip ambitions, re-ups with Qualcomm

Elsewhere: It also comes ahead of this week's highly anticipated U.S. IPO for British chip design giant Arm, which reportedly is already oversubscribed.

• Apple licenses its iPhone chip design architecture from Arm, with the two sides recently extended that relationship through 2040 (as disclosed in a regulatory filing).
• Arm, meanwhile, generates around 11% of its revenue via royalties from Qualcomm, but also is suing the chipmaker for breach of contract and trademark infringement.

The bottom line: Apple has spent both money and ink on moving its chip supply chain in-house. But just hours before the Tuesday unveiling of iPhone 15, it seems that Infinite Loop will remain reliant on outsiders for years to come.
