Shield AI Leads Week's $2 Billion Startup Funding Round

By Grace Kim

Shield AI raised $2 billion in equity, the largest single financing among U.S. startup deals announced from Oct. 31 through Nov. 6, 2026. Zipline International followed at $1.5 billion, $500 million less.

The San Diego company develops autonomy software and defense systems, along with simulation and synthetic-reality technology. Disruptive and Innovation X Capital led a $1 billion Series H. Funds managed by Blackstone added $1 billion through a structured equity investment. JPMorganChase led a separate $500 million debt financing.

Shield AI also said it is acquiring radar company Echodyne in a transaction valued at $5.3 billion. The planned deal would add radar technology to the defense supplier's portfolio.

What did the next-largest rounds fund?

Zipline International raised $1.5 billion in late-stage funding at a $21.5 billion post-money valuation. Paradigm, WCM Investment Management and Layer Global led the financing for the South San Francisco drone-delivery company.

Zipline plans to use the proceeds to expand U.S. manufacturing facilities, increase hiring and build a nationwide drone-delivery network. The announcement gives no factory capacity, delivery volume or launch schedule, leaving the expansion as a spending plan rather than a confirmed capacity commitment.

The next two companies operate in orbit and on the ground. Austin-based CesiumAstro closed $730 million in Series D financing at a valuation above $4.5 billion. Janus Henderson led the equity round. The company develops space and defense communications systems and satellites. It also secured $100 million in debt financing through the Export-Import Bank of the United States and JP Morgan.

Torrance, California-based Northwood Space raised $375 million in Series C funding for ground infrastructure that supports satellite systems. Andreessen Horowitz and DFJ Growth led the round. The three-year-old company had raised its Series B about nine months earlier.

Where did AI capital concentrate?

Applied Compute announced $350 million in new funding at a $3.25 billion valuation. Elad Gil led the financing, and Nvidia joined a long list of investors. The San Francisco company, launched 18 months ago, provides a cloud platform for enterprises and developers to train and run large AI models.

Applied Compute said its annual recurring revenue had already topped $100 million. That is the ranking's only disclosed operating-revenue figure. The round size and valuation are announced financing terms, while the revenue figure represents a company claim rather than an analyst estimate.

Three other enterprise-AI companies also raised large rounds:

• Sentra closed $150 million in a strategic investment led by Capital One Ventures. The agentic data-security company was founded in 2021 and has headquarters in New York and Tel Aviv.
• Traversal secured $120 million at a $1 billion valuation for AI agents focused on enterprise site-reliability engineering. Kleiner Perkins, Redpoint and Khosla Ventures co-led the New York startup's financing.
• Chicago-based Ocient raised $100 million in Series C funding for enterprise agentic AI focused on data analytics. BOKA Capital and OCA Ventures co-led the round.

Nvidia's participation made Applied Compute the list's clearest direct link to AI compute infrastructure. The announcement did not specify Nvidia's investment size or any resulting chip-supply agreement.

Which other sectors joined the ranking?

Harbinger secured $240 million in Series D funding for electric-truck technology. The Garden Grove, California-based company is expanding the technology into battery storage and defense applications. Tiger Global, Capricorn Investment Group and Ridgeline led the financing.

Two startups tied for tenth place:

• Watertown, Massachusetts-based Tutor Intelligence raised $75 million in Series B funding led by Andreessen Horowitz. Its focus includes robot foundation-model training and the construction of robot workers.
• Kalepa raised $75 million in Series B financing at a $470 million valuation for AI tools aimed at the insurance industry. Updata Partners led the New York company's round.

How was the list assembled?

The ranking covers the largest announced rounds in the Crunchbase database for U.S.-based companies from Oct. 31 through Nov. 6, 2026. Most announced rounds appeared in the database, although some late-reported deals may arrive after the cutoff. Although the feature calls the list the week's top 10, the tie at 10th place produces 11 companies.

The capital spread across defense autonomy, space infrastructure, enterprise AI and robotics. The next competitive test will be delivery: whether Zipline can turn U.S. factory expansion into nationwide drone capacity and Shield AI can turn its Echodyne acquisition into a broader defense offering.
