Commerce Awards SandboxAQ $500 Million CHIPS Grant for AI Materials Discovery, Taking a Minority Equity Stake in Return
The U.S. Commerce Department will fund AI-driven work on PFAS-free chemicals, catalysts, rare earth-free magnets, and backup batteries, and take a minority equity stake in return.
Editor's Note ·
- Clarification:
- The article attributes the phrase 'addressing supply chokepoints such as China-controlled magnet materials and lithium' to TS2. TS2 supports the China-controlled magnet angle but does not mention lithium. The lithium detail traces instead to the Commerce/NIST release, which states that backup-power systems 'rely on critical minerals (e.g. lithium, cobalt) sourced primarily from China.' Both facts are accurate and present in the article's cited sources; the in-text attribution for the lithium specific should point to the Commerce release rather than TS2.
Overview
The U.S. Department of Commerce has signed a definitive agreement with SandboxAQ for a $500 million award to accelerate AI-driven discovery of materials used in semiconductor manufacturing, the department announced on June 17, 2026. The grant, made through the CHIPS Research and Development Office, comes with an unusual structure: in exchange for the funding, the Department of Commerce will receive a minority, non-controlling equity stake in SandboxAQ.
What We Know
The award funds work across four programmatic areas, all aimed at reducing U.S. reliance on foreign-controlled inputs to chipmaking. According to the Commerce Department, those areas are replacements for semiconductor-manufacturing PFAS, catalysts for semiconductor fabrication, rare earth-free magnets, and advanced battery chemistries for backup power at chip facilities. The same four areas — PFAS-free process chemicals, catalysts, rare earth-free magnets, and battery systems — are described in SandboxAQ’s own announcement.
The funding is authorized through the CHIPS and Science Act, according to Quantum Zeitgeist. The work targets “forever chemicals” known as PFAS, catalysts, rare earth-free magnets, and backup-power battery chemistries, as reported by TS2, addressing supply chokepoints such as China-controlled magnet materials and lithium.
“This award will accelerate the discovery and innovation of critical materials and reduce our reliance on foreign-controlled materials,” Secretary of Commerce Howard Lutnick said in the Commerce announcement.
At the center of the project is ReAQT, which SandboxAQ describes as “SandboxAQ’s AI simulation platform” and “the foundation for all four material programmatic areas.” In the company’s press release, SandboxAQ says “ReAQT generates its own physics-grounded training data through high-fidelity simulations, including Density Functional Theory, Molecular Dynamics, and reaction modeling, then trains SandboxAQ’s proprietary Large Quantitative Models (LQMs) on that data and integrates them directly into Design-Make-Test workflows.” The company characterizes LQMs as “AI systems trained on the laws of physics, chemistry, and biology, not human language,” according to its announcement.
The Commerce Department says the platform is “designed to compress traditional materials development timelines by combining first-principles physics and chemistry simulation, AI-driven optimization, high-throughput screening of millions of candidates, and targeted experimental validation.”
Company executives framed the award around material sovereignty. “Securing America’s semiconductor future means controlling the materials that drive this vital sector,” CEO Jack Hidary said in the company announcement. In the PR Newswire release, Hidary added that “SandboxAQ’s Large Quantitative Models are grounded in the engineering and physics needed to address the needs of our domestic semiconductor sector.” Dr. Stefan Leichenauer, the company’s VP of Engineering, said in the same company announcement that “ReAQT solves both problems by generating its own high-quality training data grounded in physics, then training our Large Quantitative Models on it.”
SandboxAQ is backed by Nvidia and was valued at $5.75 billion in April 2025, according to TS2, which cites Reuters.
What We Don’t Know
The public materials do not specify the size of the government’s equity position or how it will be valued. TS2, citing Reuters, reports that the government also stands to receive royalties if successful formulas are licensed to industrial partners, but the disbursement schedule, milestones, and timeline for moving any discovered materials into domestic manufacturing were not detailed in the announcements. The Commerce Department’s two descriptions of the stake differ slightly in wording — “non-controlling” in the Commerce release versus “non-voting” in SandboxAQ’s release — but neither quantifies it.
Analysis
The award fits a pattern in which Washington increasingly trades CHIPS funding for an equity interest rather than a conventional grant, aligning taxpayer returns with commercial success. It also reframes the CHIPS program’s focus: rather than subsidizing fab construction, this award targets the chemical and materials supply chain feeding those fabs — the PFAS coolants, catalysts, magnets, and batteries whose foreign sourcing has become a strategic concern. Whether AI-driven materials screening can compress discovery timelines enough to displace entrenched foreign suppliers remains the open question the program is funded to answer.
