SAN DIEGO – March 26, 2026 – Shield AI today announced it is raising $1.5 billion in Series G funding at a $12.7 billion post-money valuation and $500 million in fixed-return preferred equity financing. The Series G is led by Advent International and co-led by the Strategic Investment Group of JPMorganChase’s Security and Resiliency Initiative, with participation from existing investors Snowpoint Ventures, InnovationX, Riot Ventures, Disruptive, Apandion, and others. Funds managed by Blackstone are investing $500 million of preferred equity financing, as well as committing an additional $250 million delayed draw facility to support future growth. Advent’s Chairman David Mussafer will join Shield AI’s Board of Directors and JPMorganChase’s Todd Combs will join as a Board Observer.  

A portion of the proceeds will help fund the company’s planned acquisition of Aechelon Technology Inc, a Sagewind Capital portfolio company. Aechelon is a defense software company known for its high-fidelity simulation, physics-based sensors, and synthetic reality applications. Aechelon’s technology is used by the U.S. military and allies to train pilots and test advanced aircraft and autonomous systems before live flight, and supports a range of critical national security platforms, including the Pentagon’s Joint Simulation Environment (JSE). 

Together, these investments reflect a fundamental shift in how defense capabilities are built: increasingly shaped in software, trained in simulation, and improved through use.
