Shield AI Acquires Radar Maker Echodyne for $5.3 Billion, Hits $28.8 Billion Valuation

A Defense AI Giant Takes Shape

Shield AI, the San Diego-based company behind the Hivemind autonomous AI platform used in military jets and drones, agreed on November 5 to acquire radar manufacturer Echodyne in a deal valued at up to $5.3 billion. Alongside the acquisition, Shield AI is raising $2.5 billion in new capital — bringing its post-money valuation to $28.8 billion, more than doubling its $12.7 billion valuation from March 2026.

Who Is Echodyne?

Founded in 2014 and backed by Bill Gates, Echodyne builds compact, solid-state phased-array radars used in counter-drone and security systems across more than 40 countries. The Kirkland, Washington company recently secured a U.S. Army contract with a $250 million ceiling from Joint Interagency Task Force 401, covering counter-uncrewed systems work. Its manufacturing facility can produce roughly 30,000 radar units per year.

Under the deal terms, $4.8 billion is paid at closing, with up to an additional $500 million contingent on Echodyne hitting agreed financial performance targets. Closing is expected in early 2027, subject to regulatory approval.

Financing the Deal

To fund the acquisition, Shield AI is raising $2.5 billion across three tranches: a $1 billion Series H equity round priced at the new $28.8 billion valuation, a $1 billion structured equity investment from funds managed by Blackstone, and $500 million in debt led by JPMorgan Chase Bank. J.P. Morgan Securities advised Shield AI on the transaction, while Morgan Stanley and Robert W. Baird advised Echodyne.

Building a Vertically Integrated Defense Tech Company

Shield AI CEO Gary Steele described the combined entity as organized around three business units: autonomy software, autonomous systems, and mission systems. Adding Echodyne's radar stack to Shield AI's existing Hivemind autonomy platform creates an end-to-end capability — the AI brain, the aircraft or drone platform, and now the sensing hardware — all within one company.

"This acquisition radically accelerates our work to meet growing customer demand for multi-mission capability," Steele said in a statement. Both companies expect triple-digit revenue growth in fiscal year 2026.

Third Acquisition in 18 Months

This is Shield AI's third acquisition since April 2025, reflecting an aggressive consolidation strategy in the defense autonomy market as Pentagon spending on autonomous systems continues to grow. The Echodyne deal is by far the largest of the three, more than ten times Shield AI's previous acquisition spending combined.

The deal expands Shield AI's physical footprint in Washington state, where Echodyne has significant manufacturing operations, adding to the company's existing presence in San Diego and other defense corridor locations.
