GM and Micron Sign Chip Deal Amid AI Data Centre Squeeze

The expansion of AI data centres across the US is applying pressure to the global semiconductor supply chain – a dynamic restricting hardware access for other sectors. 

In this context, General Motors signed a strategic agreement with Micron Technology to try and bypass this constraint, securing memory and storage platforms for vehicle production while components remain oversubscribed.

Moody's indicates the average car currently requires more than 1,700 chips. More advanced vehicles require even more. The New York Times reports vehicles with greater technological complexity require more than 3,000 chips. 

Currently, 23 General Motors vehicle models offer the company's Super Cruise technology. Advanced driver assistance systems depend on reliable memory hardware, forcing automakers to compete directly with data centre operators for factory allocations.

Through the agreement, General Motors will secure low-power, double data rate components, NOR flash memory and universal flash storage semiconductor products. The companies agreed to align on future product definition, system-level optimisation and the qualification of advanced memory technologies for the next generation of vehicles.

Impact of AI infrastructure

Hyperscale AI clusters consume unprecedented amounts of DRAM and flash memory alongside GPUs. As cloud providers accelerate AI infrastructure investment, semiconductor manufacturers are balancing demand from data centres with automotive, industrial and consumer electronics customers, prompting some industries to secure long-term supply agreements.

The tension between data centre hardware requirements and automotive manufacturing recently emerged as a formal issue for US government officials. 

The Alliance for Automotive Innovation, an industry group where General Motors is a founding member, coordinated with other industry representatives to highlight supply chain vulnerabilities in a letter to US Treasury and Commerce Secretary Howard Lutnick in June 2026.

“Expanding AI data centres consume an enormous share of available memory chip capacity,” the letter states. “The result has been an unprecedented surge in the price of memory chips and reduced supply of these chips for manufacturing and consumer-facing industries.”

“These risks to large parts of the US economy are occurring despite major US investments in chip manufacturing intended to precisely avoid this type of supply chain disruption,” the group added.

Moody's notes that semiconductor networks are multi-tiered, meaning disruption cascades across production, revenue and delivery timelines. 

The firm projects the advanced driver assistance market to grow from 359.8 million units in 2025 to 652.5 million units by 2032, a compound annual growth rate of 8.9%. As vehicles become technology-intensive, the automotive industry grows exposed to the suppliers manufacturing these parts.

Securing vehicle components

Mary Barra, Chair and CEO of General Motors, says: “Delivering next-generation vehicles at scale requires a resilient and closely aligned supply chain.

“Our expanded collaboration with Micron strengthens our access to critical memory technologies while enabling deeper integration across our vehicle platforms, supporting both performance and long-term reliability. This agreement reinforces the supply chain needed to support future vehicle innovation and production.”

The agreement provides General Motors with longer-term supply certainty as memory markets tighten under growing demand from AI infrastructure.

Localised memory manufacturing

Micron indicates the agreement relies on ongoing investments to expand supply for automotive clients, including 1-alpha DRAM manufacturing capabilities in Manassas, Virginia. 

The firm invested US$2bn to modernise the Manassas fabrication plant, which began production earlier in the year.

Currently, about half of the cars on US roads today feature a Micron component manufactured at the Manassas plant.

“We are proud to expand our strategic relationship with GM to deliver both long-term supply assurance and technology innovation critical to the future of the automotive industry,” says Sanjay Mehrotra, Chairman, President and CEO of Micron.

“As demand for memory and storage continues to grow, we are investing to extend supply availability, expand capacity and align more closely with our customers to improve supply predictability across the automotive ecosystem. 

“Our expanding manufacturing efforts in the US are designed to enable GM to deliver both near-term products as well as secure US-based supply to support next-generation platforms and innovation.”
