ASI, the frontier AI company focused on critical infrastructure and national security, has raised US$325 million in Series C financing at a US$3 billion valuation. The round was led by Spark Capital, with participation from Citadel Securities affiliates, Meritech Capital, Craft Ventures, Energy Impact Partners, and Andreessen Horowitz. The funding will help ASI expand its predictive AI systems across energy, logistics, and defense environments.
Addressing Critical Infrastructure Challenges
America's critical systems, including air traffic control, electrical grids, and defense logistics, often operate at or beyond their design limits. ASI says these operations remain manual and reactive because human operators can only track limited information in real time. The company's platform uses continuous forward simulations and multidimensional monitoring to show what is likely to happen hours, days, and weeks ahead.
Deployment Across Public and Private Sectors
ASI's technology is already active in several high-stakes areas. The US Department of Transportation and Federal Aviation Administration awarded ASI a US$875 million program of record to modernize the National Airspace System. The US Army also awarded a US$99 million contract to scale the technology across modernized command and control efforts, including the Next Generation Command and Control program.
In commercial aviation, ASI supports major airlines such as Delta Air Lines, Alaska Airlines, and United Airlines. National Grid, a utility serving more than 20 million people in the Northeast, has partnered with ASI for electric grid planning and operations. These deployments highlight the company's role across transportation, defense, and energy.
Investor Confidence in Decision Intelligence
Spark Capital General Partner Clay Fisher described ASI as a generational category creator that runs the physical world and orchestrates its most valuable assets. He noted that the US$875 million federal program of record and commercial adoption with airlines and power networks prove ASI is sovereign infrastructure. Fisher also called ASI one of just four neoprimes with production contracts of this size with the US government.
Craft Ventures Partner Michael Robinson said some of the most valuable AI applications will be in complex, real-world systems with thousands of interconnected assets. He pointed to the FAA work and the US$99 million US Army contract as examples of ASI's impact in aerospace and defense. Robinson added that the same technology is already showing value in energy and logistics.
Energy Impact Partners Managing Partner Sameer Reddy emphasized the rise in electricity demand and the need for grid reliability. He said mission-critical institutions already trust ASI to run complex operations, and that same technology now helps utilities like National Grid anticipate disruption. Reddy described energy as a major growth opportunity for the company.
Scaling for the Future
ASI plans to use the Series C capital to accelerate deployment across energy, logistics, and tactical edge environments. The company will also expand its frontier AI research and engineering teams headquartered in Boston. ASI currently operates from additional offices in Washington, DC, Denver, and Europe, supporting its government and commercial customers.
ASI's funding round reflects growing investor appetite for AI systems that manage physical infrastructure rather than text generation. The company's existing federal contracts and commercial partnerships provide a foundation for broader adoption in critical sectors. With new capital and a US$3 billion valuation, ASI aims to become the automated nervous system keeping America running.
