Shield AI, the San Diego-based maker of autonomous drone software, said Thursday it has agreed to acquire radar manufacturer Echodyne for up to $5.3 billion and raised a $2.5 billion financing package to help pay for it, pushing its own valuation to $28.8 billion — more than double the $12.7 billion mark it reached as recently as March. The financing includes $1 billion in new Series H equity, co-led by Disruptive and Innovation X Capital with participation from Advent, a further $1 billion in structured equity from funds managed by Blackstone, and $500 million in debt arranged by JPMorgan Chase Bank.
The Echodyne deal itself is structured in two parts: $4.8 billion payable at closing and another $500 million contingent on the radar maker hitting performance targets. Echodyne, which is backed by Bill Gates, makes software-defined radar systems the companies say will be folded into Shield AI's "Mission Systems" business, extending its autonomous-flight software into detecting, tracking and defeating hostile drones — a category the industry calls counter-unmanned aircraft systems, or counter-UAS.
A rapid run-up in value
The acquisition is expected to close in early 2027, pending regulatory approval, and Echodyne is set to continue operating with its existing team under Shield AI's ownership. J.P. Morgan Securities served as Shield AI's financial adviser on the transaction. The deal is the latest step in a valuation climb that has moved unusually fast even by the standards of the current venture market: from roughly $5.3 billion in March 2025 to $12.7 billion this past March and now $28.8 billion, driven largely by growing demand from the Pentagon and allied militaries for autonomous systems that do not rely on GPS or constant human piloting.
The purchase fits a broader pattern among well-funded defense-technology companies of acquiring rather than building sensor and hardware capabilities, as investors increasingly treat the sector's valuations more like those of software companies than traditional contractors. Shield AI has made a series of acquisitions in the past two years to round out its technology stack, and the Echodyne deal extends that strategy into radar — a capability seen as increasingly central to countering the proliferation of cheap drones in conflicts from Ukraine to the Middle East.
The round adds to what has been an unusually active year for venture-scale checks into AI-adjacent defense and infrastructure startups, as investors chase companies they see as benefiting from both the AI buildout and rising government spending on autonomous systems. Whether Shield AI's valuation holds will depend in part on how quickly it can integrate Echodyne's radar technology and on the pace of Pentagon contracting, which has historically moved more slowly than venture investors would like.
