The United States is taking a significant step to reduce its dependence on China for critical semiconductor materials. In June 2026, the Department of Commerce announced a $500 million investment in SandboxAQ, a California-based technology company that uses advanced artificial intelligence to discover new materials and chemical solutions for strategic industries. The goal is straightforward: strengthen America’s semiconductor supply chain, reduce reliance on foreign-controlled materials, and improve national security.

Why This Investment Matters

For years, China has built a dominant position in several critical material supply chains that support semiconductor manufacturing. China controls roughly 70 percent of global rare earth mining output and more than 90 percent of refining and separation capacity. Chinese firms also control more than two-thirds of global processing capacity for key battery minerals such as lithium and cobalt. These materials play an important role in the production of advanced chips and the equipment used to manufacture them.

The Trump administration views this dependence as both an economic and national security vulnerability. Commerce Secretary Howard Lutnick summarized the purpose of the investment, stating, “This award will accelerate the discovery and innovation of critical materials and reduce our reliance on foreign-controlled materials.”

Rather than simply funding another manufacturing facility, the government is investing in the discovery of entirely new materials that could replace components currently sourced through supply chains heavily influenced by China.

Who Is SandboxAQ?

SandboxAQ was spun out of Alphabet, Google’s parent company, in 2022 and now operates as an independent firm. While many people associate artificial intelligence with chatbots and language models, SandboxAQ specializes in a very different type of AI.

The company develops what it calls Large Quantitative Models, or LQMs. These systems are trained on scientific data rather than language. They are designed to solve complex problems in chemistry, physics, and materials science. Instead of generating text, they analyze millions of possible compounds and material combinations to identify promising candidates before scientists ever enter a laboratory.

According to the company, this approach can dramatically shorten development timelines. SandboxAQ reports that one of its catalyst-development platforms used 13.5 million simulations and can evaluate potential materials roughly 20,000 times faster than conventional methods.

The Commerce Department described SandboxAQ’s platform as combining first-principles physics and chemistry simulation, AI-driven optimization, high-throughput screening of millions of candidates, and targeted experimental validation. This allows researchers to move much faster from concept to practical testing.

The Four Priority Areas

The government funding will focus on four strategic areas that directly affect semiconductor manufacturing and where foreign supply chain dependence remains a concern.

First, SandboxAQ will work on developing replacements for PFAS chemicals used in semiconductor manufacturing. These materials are commonly used in heat transfer systems, lubricants, insulating coatings, and surface treatments. The goal is to create alternatives that perform as well as existing products without creating environmental concerns.

Second, the company will develop advanced catalysts used in semiconductor fabrication. Domestic catalyst development could reduce foreign control over important manufacturing processes and intellectual property used throughout the semiconductor ecosystem.

Third, SandboxAQ will focus on rare earth-free magnets. Rare earth magnets are critical components in semiconductor manufacturing equipment, powering precision actuators, vacuum pumps, and wafer-positioning systems. Because China controls more than 90 percent of global production of neodymium-based permanent magnets, finding alternatives could significantly reduce U.S. exposure to foreign supply disruptions.

Fourth, the company will research advanced battery chemistries for backup power systems used in semiconductor fabrication facilities. Today’s systems often rely on lithium and cobalt supply chains that are heavily influenced by China. Developing alternative battery technologies based on domestically accessible materials could strengthen supply chain security and reduce vulnerability to foreign restrictions.

What Are PFAS and Why Are They a Concern?

PFAS stands for perfluoroalkyl and polyfluoroalkyl substances. They are often referred to as “forever chemicals” because they can persist in the environment for long periods. According to the Commerce Department, SandboxAQ will seek PFAS-free alternatives that meet semiconductor manufacturing performance requirements while avoiding environmental toxicity and bioaccumulation risks.

The ability to replace PFAS with effective domestic alternatives would not only address environmental concerns but could also reduce dependence on specialized foreign-controlled chemical supply chains that support chip production.

Countering China’s Leverage

At its core, this initiative is about reducing strategic vulnerability. China has repeatedly demonstrated its ability to influence global supply chains through its dominance of critical minerals and advanced materials processing. If restrictions were imposed on materials used in semiconductor manufacturing, the United States could face disruptions affecting everything from consumer electronics to military systems.

By using AI to discover alternative materials, catalysts, magnets, and battery chemistries that can be sourced and manufactured domestically, the United States hopes to weaken China’s leverage over these critical industries. The strategy is not simply to compete for existing resources, but to create entirely new solutions that bypass foreign-controlled bottlenecks.

Ron Ash on Maintaining America’s Advantage

The broader significance of SandboxAQ’s technology extends beyond materials science. Ron Ash, CEO of Accenture Federal Services, emphasized the importance of staying ahead of emerging technological threats. He stated, “This Executive Order is a decisive signal that cybersecurity must advance with AI and quantum capabilities.” Ash also noted that “our work with SandboxAQ ensures America’s critical infrastructure will outpace future technological threats.”

His comments highlight a growing view within government and industry that advanced AI platforms like those developed by SandboxAQ can play a crucial role in strengthening America’s technological position against strategic competitors.

The $500 million investment represents more than a research grant. It is part of a broader effort to build resilient domestic supply chains, reduce exposure to Chinese restrictions, and ensure that the United States maintains leadership in the technologies that will shape the future.
