Shield AI raises $2 billion at $12.7 billion valuation, acquires Aechelon Technology

Shield AI Secures $2 Billion in Combined Funding

Shield AI announced on Thursday that it has raised $2 billion in combined funding at a $12.7 billion valuation, more than doubling the $5.3 billion valuation it achieved just a year ago in March 2025 2

2

. The raise comprises a $1.5 billion Series G funding round led by Advent International and co-led by JPMorgan Chase's Security and Resiliency Initiative, alongside $500 million in preferred equity from funds managed by Blackstone 2

2

. Blackstone also committed an additional $250 million in a delayed-draw facility 2

2

. The San Diego-based defense technology startup will use part of the proceeds to acquire Aechelon Technology, a smaller defense-tech company specializing in flight simulation software that supports the Pentagon's Joint Simulation Environment 1

Rapid Growth Driven by Military Modernization

Shield AI is projecting more than 80% revenue growth by the end of 2026, which would equate to at least $540 million in revenue this year, according to cofounder Brandon Tseng and CFO Kingsley Afemikhe 3

3

. "We don't expect growth to slow down," Tseng told Fortune 3

3

. The company's valuation has grown nearly fivefold in roughly two and a half years, rising from $2.7 billion in October 2023 2

2

. Gary Steele, Shield AI's chief executive and former Cisco executive, emphasized that "A.I. plus autonomy is changing the game in the military," noting that the capabilities and cost curve the company can deliver are fundamentally different from the past 1

Hivemind Powers Autonomous Combat Pilot Systems

At the core of Shield AI's technology is Hivemind, an autonomous combat pilot system that operates aircraft using onboard sensors and reasoning rather than relying on external navigation signals 2

2

. This enables GPS-independent operation in environments where GPS is jammed or unavailable and communications are severed, conditions the military designates as DDIL (disconnected, degraded, intermittent, or low-bandwidth) 2

2

. Shield AI's V-BAT drone, powered by Hivemind, has logged more than 130 sorties in Ukraine since June 2024, operating in conditions of pervasive electronic warfare 2

2

. Ukrainian forces used the V-BAT surveillance drone to locate a Russian SA-11 Buk-M1 mobile air defense system in a heavily jammed environment 2

2

. Tseng declined to say whether Shield AI's drones have been deployed in Iran, but noted the company operates "in almost every single conflict zone" 3

Acquisition of Aechelon Technology Enhances AI Training Capabilities

The acquisition of Aechelon Technology fits into Shield AI's strategy to build what it describes as a "Hivemind Foundation Model for Defence," a domain-specific artificial intelligence model that integrates simulation data with real-world operational data 2

2

. Aechelon builds high-fidelity simulation environments used by the US military and allied forces to train pilots and test autonomous systems before live flights 2

2

. Its platform provides synthetic aerial footage designed to simulate a pilot's field of view and can incorporate weather simulations, radar measurements, and infrared data 4

4

. For Shield AI, Aechelon provides the synthetic training data that Hivemind needs to improve across new aircraft types and mission profiles without the cost and risk of live flight testing 2

2

. Aechelon's platform will remain open to other customers following the acquisition, Tseng said 3

Investor Appetite for National Security Technologies Surges

Shield AI's raise arrives amid record capital flows into defense technology, with venture capital deals in the sector reaching $49.1 billion in 2025, nearly double the $27.2 billion recorded the previous year, according to PitchBook 2

2

. Advent International's managing partner Shonnel Malani stated, "We believe Shield AI represents the frontier of this transformation and we look forward to partnering with the company as it scales its vision of AI-driven autonomy, helping shape a future where intelligent systems can enhance resilience, protect service members, and redefine the nature of modern security" 5

5

. The private equity firm plans to make a $1 billion investment into companies specializing in next-generation defense technologies and has allocated over $15 billion since 2020 to various defense companies 5

5

. Tseng told Fortune that fundraising discussions began in November, and investor sentiment has shifted alongside "a broad observation" that the world has become less stable, with countries around the world modernizing their militaries 3

Competition and Future Air Operations

Shield AI faces competition from Anduril, which raised $2.5 billion at a $30.5 billion valuation in June 2025 and was reported in March 2026 to be pursuing a $4 billion round at a $60 billion valuation 2

2

. Shield AI unveiled the X-BAT in October 2025, a VTOL stealth fighter drone that requires no runway, can be deployed from ships, and is piloted entirely by Hivemind 2

2

. The company has said its first vertical takeoff flight is scheduled for this year, with operational deployment estimated for 2028 2

2

. The X-BAT represents Shield AI's move from reconnaissance into strike capability, a significant expansion of the company's addressable market 2

2

. The transaction with Shield AI is anticipated to conclude in the second quarter of 2026, pending customary regulatory approvals 5
