Apple Inc said it is expanding its partnership with chipmaker Broadcom in a multi-year deal expected to be worth more than $30 billion, marking the iPhone maker's largest U.S. manufacturing commitment to date.

The deal announced by Apple on Wednesday will enable the production of more than 15 billion U.S.-made chips and includes a $1.5 billion expansion of Broadcom's factory in Fort Collins, Colorado. Apple did not provide a timetable for when the new production capacity would come online.

Broadcom has long supplied Apple with connectivity components, but the new deal deepens their partnership in custom chips in the United States. Apple said Broadcom will make wireless components that help devices connect to cellular, Wi-Fi and Bluetooth networks.

Broadcom disclosed in a filing with the U.S. Securities and Exchange Commission on Monday that it has reached a new long-term agreement with Apple to develop and supply "custom ASIC chip products" for multiple generations of Apple products until 2031. ASICs, or application specific integrated circuits, are increasingly used for artificial intelligence workloads.

For outgoing Apple CEO Tim Cook, the agreement marks the latest move to boost investment in U.S. manufacturing, a focus of the Trump administration. This is the largest investment in the company’s four-year, $600 billion U.S. investment plan announced in 2025, and the largest commitment to date under its “Made in America Plan” to expand domestic production of supply chains.

"Apple has been working with the U.S. government and businesses across the country to help build an end-to-end silicon supply chain in the United States, and today's announcement advances those efforts," Apple said in a press release.

Cook said components produced in Fort Collins are "critical" to the performance and connectivity Apple customers expect and thanked President Donald Trump and his administration for their support of the project.

Broadcom CEO Fuyang Chen said Apple's commitment will help the chipmaker expand its manufacturing footprint in Fort Collins.
