Shield AI's $2 Billion Round Leads a $5.3 Billion M&A Week

Defense tech startup Shield AI just closed $2 billion in equity plus $500 million in debt — the largest U.S. startup round of the week ending Nov. 6, 2026, per Crunchbase data. And the San Diego-based company didn't stop at fundraising: it also announced it's acquiring radar maker Echodyne in a deal valued at $5.3 billion.

The equity portion splits two ways. A $1 billion Series H was led by Disruptive and Innovation X Capital, and funds managed by Blackstone put in another $1 billion as a structured equity investment. JPMorganChase led the $500 million debt financing. Shield AI builds autonomy software for defense platforms, along with simulation and synthetic reality technology.

Who else raised big?

Drone delivery company Zipline International landed the week's second-largest check: $1.5 billion in late-stage funding at a $21.5 billion post-money valuation. Paradigm, WCM Investment Management and Layer Global led the round. The South San Francisco company plans to spend it expanding U.S. manufacturing and hiring as it builds a nationwide drone delivery network.

Space tech took two of the top four slots. Austin-based CesiumAstro, which develops space and defense communications systems and satellites, closed $730 million in Series D financing at a valuation above $4.5 billion. Janus Henderson led the equity round, with another $100 million in debt coming through the Export-Import Bank of the United States and JP Morgan. Northwood Space, a Torrance, California maker of ground infrastructure for satellite systems, raised $375 million in Series C funding led by Andreessen Horowitz and DFJ Growth — just nine months after its Series B.

AI infrastructure also drew sizeable checks. Applied Compute, a San Francisco cloud platform for training and running large AI models, raised $350 million at a $3.25 billion valuation. Elad Gil led the financing, with Nvidia among a long list of participants. The company launched only 18 months ago and says annual recurring revenue has already topped $100 million.

What does this week change for investors and founders?

The mid-table shows where growth money is rotating. Harbinger, an electric truck startup expanding into battery storage and defense applications, secured $240 million in Series D funding led by Tiger Global, Capricorn Investment Group and Ridgeline. Sentra, a New York- and Tel Aviv-based provider of agentic data security tools founded in 2021, closed a $150 million strategic investment led by Capital One Ventures.

Agentic AI landed twice more:

• Traversal raised $120 million at a $1 billion valuation for its AI agents targeting enterprise site reliability engineering. Kleiner Perkins, Redpoint and Khosla Ventures co-led the New York startup's round.
• Ocient, a Chicago company building agentic AI for enterprise data analytics, picked up $100 million in Series C funding co-led by BOKA Capital and OCA Ventures.

Two $75 million Series B rounds tied for tenth place. Tutor Intelligence, a Watertown, Massachusetts startup training robot foundation models and building robot workers, raised its round led by Andreessen Horowitz — the firm's second appearance in this week's top ten. Kalepa, which sells AI tools to the insurance industry, secured $75 million at a $470 million valuation in a round led by Updata Partners.

The read-through

Together, the ten deals total more than $5.9 billion in announced funding for the Oct. 31–Nov. 6 window. Defense and hard-tech categories — drones, satellites, ground stations, electric trucks, robotics — account for seven of the ten rounds, a shift away from pure software at the top of the market. For founders in autonomy, space and physical AI, this week confirms that the largest checks in late 2026 are following hardware-rich, government-adjacent business models, and that structured equity and debt are now standard tools for scaling them.
