US awards $500 million to Nvidia-backed SandboxAQ for finding new chipmaking materials

SandboxAQ will develop alternatives to PFAS, catalysts, magnets and batteries for chipmaking as the Commerce Department takes a minority stake.

  • On Wednesday, the U.S. Department of Commerce awarded startup SandboxAQ $500 million in CHIPS Act funding to develop materials for domestic semiconductor manufacturing and reduce reliance on foreign-controlled supply chains.
  • Targeting four areas where U.S. chipmaking relies on foreign sources—PFAS substitutes, catalysts, rare earth-free magnets, and battery systems—the award addresses a strategic vulnerability: China controls more than 90 percent of global neodymium-based magnets.
  • SandboxAQ will leverage physics-based "Large Quantitative Models" to screen millions of candidate materials, compressing development timelines from years to weeks by generating training data grounded in physical laws rather than human text.
  • Under the agreement, Commerce will receive a minority, non-voting equity stake in SandboxAQ and royalty payments if research yields commercially viable formulations for mass production.
  • Secretary of Commerce Howard Lutnick stated the award aims to strengthen national security by accelerating innovation in critical materials, supporting the broader CHIPS Act goal of reigniting domestic semiconductor manufacturing.
