NVIDIA and Oracle have announced a transformative collaboration to build the U.S. Department of Energy’s largest AI supercomputer at Argonne National Laboratory, marking a pivotal moment in the nation’s scientific and technological advancement. The project, named Solstice, will feature a record-breaking 100,000 NVIDIA Blackwell GPUs and will serve as a cornerstone for AI-driven scientific discovery across the United States. Complementing Solstice, a second system called Equinox will include 10,000 NVIDIA Blackwell GPUs and is expected to be operational in the first half of 2026. Together, the two systems will deliver a combined 2,200 exaflops of AI performance, powered by advanced NVIDIA networking and optimized for large-scale AI workloads. Both systems will be hosted at Argonne National Laboratory, a leading research institution at the forefront of scientific innovation. The supercomputers will enable researchers to develop, train, and scale next-generation AI models using the NVIDIA Megatron-Core library and deploy them efficiently with the NVIDIA TensorRT™ inference software stack. These models will form the foundation of agentic AI workflows—autonomous, reasoning-driven systems designed to accelerate scientific exploration across disciplines such as healthcare, materials science, climate modeling, and energy research. The initiative is part of a new public-private partnership model led by the DOE, incorporating industry investment and real-world use cases. This approach reflects the Trump Administration’s commitment to strengthening America’s leadership in artificial intelligence and science through strategic innovation partnerships. Jensen Huang, founder and CEO of NVIDIA, emphasized the significance of the project, stating, “AI is the most powerful technology of our time, and science is its greatest frontier. Together with Oracle, we’re building the Department of Energy’s largest supercomputer—America’s engine for discovery—giving researchers access to the most advanced AI infrastructure to drive progress across critical fields.” U.S. Secretary of Energy Chris Wright highlighted the importance of collaboration, saying, “Winning the AI race requires new and creative partnerships that bring together the brightest minds and industries. The Solstice and Equinox systems represent a new common sense approach to computing, turning shared innovation into national strength. Thanks to President Trump, we’re bringing new computing capacity online faster than ever before.” Paul K. Kearns, director of Argonne National Laboratory, noted the systems’ integration with cutting-edge experimental facilities like the Advanced Photon Source, enabling real-time data analysis and deeper scientific insight. “We’re preparing thousands of researchers to leverage these groundbreaking capabilities, ensuring that public research dollars deliver tangible breakthroughs,” he said. Clay Magouyrk, CEO of Oracle, underscored the role of sovereign, high-performance computing, stating, “We are proud to partner with the Department of Energy to deliver secure, scalable AI infrastructure. Our collaboration with NVIDIA and Argonne will provide a critical resource to address the nation’s most complex challenges and accelerate the next wave of scientific discovery.” The Solstice and Equinox systems will serve as a foundation for broader national efforts in science, energy, and national security, reinforcing U.S. leadership in AI for decades to come.
