SandboxAQ Gets $500M as Trump Pushes Rare Earth Independence From China
What You Need to Know
- Trump administration invests $500 million in SandboxAQ for semiconductor materials and PFAS replacements.
- SandboxAQ trains AI models on physics and laboratory data, not text or code.
- China controls majority of global rare earth supply critical for semiconductor manufacturing.
- Government takes minority equity stake with no voting rights or board representation.
The Trump administration is taking an equity stake in SandboxAQ and directing $500 million toward the company to develop semiconductor materials, including replacements for PFAS compounds and alternatives to rare earth inputs currently sourced from overseas. The funding comes from CHIPS Act research money, following earlier awards of $150 million for semiconductor production tools and $2 billion into quantum computing.
SandboxAQ occupies an unusual position in the AI landscape: its models are trained on laboratory measurements and physics data rather than text or code, making them applicable to material science problems that conventional large language models handle poorly. The company, valued at $5.75 billion in April 2025 and backed by Nvidia, had already applied this approach to biotechnology and quantum navigation before the federal contract. The government’s minority stake carries no voting rights and includes no board seat, according to CEO Jack Hidary, which structurally resembles a strategic grant more than a conventional equity investment. That framing matters because it limits political entanglement while still giving Commerce a financial interest in the outcome.
The rare earth angle is the actual pressure point here: China controls much of the global rare earth supply that semiconductor manufacturers, automakers, and defense contractors depend on.
The Entity List Problem Running in Parallel
Alongside this investment, a separate story is unfolding at the same agency that complicates the supply-chain independence narrative. According to sources, DeepSeek, Chinese memory chip producer CXMT, and more than 100 other firms flagged as national security threats have cleared an interagency review but have not been added to Commerce’s Entity List. At least 75 Chinese entities tied to advanced chip production and AI development were reportedly approved for blacklisting and never formally published. Since late 2025, Jeffrey Kessler, under secretary of commerce for industry and security, has reportedly worked to prevent new Chinese names from being published over concerns about worsening bilateral relations.
The contradiction is direct: the administration is spending CHIPS Act money to reduce dependence on Chinese materials while simultaneously holding back the trade enforcement tools designed to pressure the companies supplying those materials. Critics of the Bureau of Industry and Security have argued this reflects a broader pattern of delayed action on export controls, including a Biden-era AI chip regulation the agency promised to replace early last year that has yet to materialize. China’s foreign ministry, for its part, said Washington should stop “weaponizing” export control measures against Chinese enterprises. Whether the SandboxAQ investment produces commercially viable rare earth substitutes fast enough to matter is a separate question from whether enforcement policy keeps pace with the stated strategic goal, and right now those two timelines are not aligned.
