Apple commits $600B to US chip supply chain with Broadcom deal

Tim Cook's $600 billion US manufacturing pledge positions Apple and Broadcom as the twin pillars of America's semiconductor reshoring push.

Apple Chief Executive Tim Cook said the company's deepening partnership with Broadcom is a critical step toward building a US end-to-end chip supply chain, as the iPhone maker commits $600 billion to domestic manufacturing through 2028.

"Our work with Broadcom is a key part of achieving a truly American end-to-end semiconductor supply chain," Cook said in a statement July 31, without disclosing specific financial terms of the expanded collaboration.

The commitment includes a new $100 billion tranche for US-based suppliers, building on an earlier $500 billion pledge made earlier this year. Apple has already committed over $30 billion to Broadcom for producing 15 billion US-made chips, according to prior disclosures. The broader plan also encompasses $2.5 billion for Corning's Kentucky glass facility and expanded output from TSMC's Arizona fab, which will produce tens of millions of advanced chips for future iPhones.

The investment push comes as President Donald Trump threatens 100 percent tariffs on semiconductor imports, making domestic supply chain control a financial imperative. Apple's stock gained 5 percent on the announcement, signaling investor confidence in Cook's ability to navigate trade tensions while maintaining access to Asian assembly lines for final product assembly.

Broadcom's Expanding Role in Apple's Silicon Roadmap

Broadcom has emerged as Apple's most critical US chip partner beyond TSMC. The company supplies custom 5G modem components, wireless connectivity chips, and power management ICs for Apple devices. The expanded partnership deepens Broadcom's integration into Apple's silicon strategy, which has increasingly moved away from Qualcomm and Intel for core components.

Broadcom separately secured $230 billion in new deals across its semiconductor and infrastructure software businesses, the company disclosed in its most recent earnings. The Apple relationship positions Broadcom to capture a growing share of the $600 billion US manufacturing commitment.

The Geopolitical Calculus Behind Cook's Pledge

Cook's strategy serves dual purposes: insulating Apple from punitive tariffs while preempting political pressure to move iPhone assembly to the US. The $600 billion figure covers components including chips and glass but explicitly excludes final product assembly, which remains concentrated in China and India.

TSMC's Arizona facility, where Apple is the largest customer, will produce chips on advanced nodes for future iPhones. Apple's partnerships with Texas Instruments, GlobalFoundries, and Applied Materials further broaden the domestic sourcing network. The company also reaffirmed its $2.5 billion investment in Corning's Kentucky plant for cover glass production.

Investment Implications

Apple trades at roughly 30 times forward earnings, a premium reflecting its resilient supply chain and services revenue growth. The $600 billion commitment, while large in absolute terms, represents a modest shift in Apple's overall manufacturing footprint — the company spent over $200 billion on supply chain costs in fiscal 2025 alone. The real financial impact will depend on how much of the investment flows through to Apple's cost of goods sold versus being absorbed by suppliers.

For Broadcom, the deepening Apple relationship adds to a year of record deal-making. The company's stock has gained more than 60 percent over the past 12 months, driven by AI networking and custom chip demand. The Apple partnership provides a stable revenue base as Broadcom competes with Marvell and Qualcomm for custom silicon wins.
