Apple and Broadcom recently agreed to expand their longstanding partnership until 2031. A move that suggests a complete switch to the iPhone-maker’s own C-series chips may still be several years away.
According to a Securities and Exchange Commission (SEC) filing on the 6th July 2026, Broadcom will develop and supply a range of custom ASIC chips for use across multiple generations of Apple products.
The chips include radio frequency components used in iPhones for cellular connectivity, along with Wi-Fi and Bluetooth connectivity chips and other networking semiconductors.
Broadcom has been a long-standing supplier to Apple. Analysts estimate Apple accounts for roughly 20% of its annual revenue, making it one of the chipmaker’s largest customers.
The companies previously struck a multibillion-dollar agreement in 2023 covering Broadcom’s development and manufacture of 5G radio frequency components.
The extended partnership reinforces Apple’s broader strategy of locking in long-term supply agreements with key chipmakers to strengthen the resilience of its supply chain.
In May 2026, Apple and Intel reportedly reached a preliminary agreement for the latter to manufacture some of the chips which power iPhones, iPads and other devices.
Last month, Apple cited memory chip shortages caused by AI infrastructure demand as it implemented hikes of 20% or more on many models of its MacBook and iPad lines, but it stopped short of any increases for the iPhone.
During an April Q2 earnings call, outgoing Apple CEO Tim Cook stated supply chain issues impacted iPhone sales.
Apple’s internally developed C1 modem made its debut early last year in its low-end 16e device. The tech giant has said the C1 chip is more power-efficient than the third-party chips used in other iPhone models
GSMArena reported in February 2026 Apple’s C2 modem is expected to be featured inside the iPhone 18 Pro series released in the coming months.
Reuters reported the C2 chips are made by TSMC to Apple’s design, while the company still relies on customised versions of third-party radio chips for some of its other products.
