Shield AI Secures $1.5B Series G at $12.7B Valuation

Shield AI, a defense technology company specializing in autonomous systems, completed a $1.5 billion Series G funding round at a $12.7 billion post-money valuation on March 26, 2026. The round was led by Advent International and co-led by JPMorganChase’s Strategic Investment Group, with participation from existing backers including Snowpoint Ventures, InnovationX, Riot Ventures, Disruptive, and Apandion. Additionally, funds managed by Blackstone provided $500 million in fixed-return preferred equity financing, along with a $250 million delayed draw facility for future expansion. This funding more than doubles the company's valuation from $5.3 billion following its $240 million raise in March 2025.

A key use of proceeds finances Shield AI's acquisition of Aechelon Technology, a developer of flight simulation software for military pilot training and a Sagewind Capital portfolio company. The deal, advised by Morgan Stanley, awaits regulatory approvals and enhances Shield AI's capabilities in simulation and training alongside its Hivemind autonomy software, V-BAT, and X-BAT aircraft. This move follows selection of Hivemind for the U.S. Air Force Collaborative Combat Aircraft program in February 2026, driving a 140% valuation increase in one year amid rising demand for autonomous defense tech.

Founded in 2015, Shield AI operates globally with facilities in the U.S., Europe, the Middle East, and Asia-Pacific, supporting military operations worldwide. The funding underscores investor confidence in defense autonomy amid geopolitical tensions and AI advancements, positioning the company to scale production and integrate acquired technologies for next-generation systems.
