VC Flooding into AI
Venture capital in March concentrated heavily in AI, with $11.46 billion raised across 316 U.S. deals and the sector accounting for about 60% of monthly venture activity. The largest rounds that month included Shield AI ($2.0 billion), Saronic ($1.75 billion) and Mind Robotics ($500 million), highlighting where capital is flowing right now. (alleywatch.com)
Artificial intelligence startups pulled in most U.S. venture money in March, even as the overall market cooled from the giant rounds that inflated February. (alleywatch.com) U.S. startups raised $19.06 billion across 630 deals in March 2026, and artificial intelligence companies took $11.46 billion of that total across 316 deals, or 60.1% of monthly funding. (alleywatch.com) The biggest March checks went to defense and robotics companies using artificial intelligence in physical systems, not just software. Shield AI announced a $2 billion financing on March 26, Saronic announced a $1.75 billion round on March 31, and Mind Robotics announced a $500 million Series A on March 11. (shield.ai, cnbc.com, businesswire.com) Shield AI said its raise includes $1.5 billion in Series G funding and $500 million in preferred equity at a $12.7 billion post-money valuation. The San Diego company said the money will support its planned acquisition of Aechelon and further development of its Hivemind autonomy software and X-BAT aircraft program. (shield.ai) Saronic said its $1.75 billion round valued the Austin company at $9.25 billion and will fund shipyard and supply-chain expansion for autonomous vessels. Chief executive Dino Mavrookas told CNBC the company aims to build more than 20 ships a year by 2027. (cnbc.com) Mind Robotics said its $500 million Series A follows a $115 million seed round in late 2025 and will fund industrial robots for factory work that needs human-like dexterity and adaptation. The company said it was founded in 2025 and is led by Rivian chief executive RJ Scaringe, with Rivian as a partner and major shareholder. (businesswire.com) March still looked smaller than the prior two months because 2025 and early 2026 were distorted by a handful of outsize rounds. AlleyWatch said March funding fell 64.4% from March 2025, when OpenAI raised $40 billion, and 69.5% from February 2026, when Anthropic raised $30 billion and Waymo raised $16 billion. (alleywatch.com) The stage mix shows investors still favoring companies that are already scaling. AlleyWatch said 45 late-stage deals captured $8.91 billion in March, or 46.7% of all capital raised that month. (alleywatch.com) The geography was broader than a typical San Francisco-heavy month. AlleyWatch said New York captured 20.7% of March funding, followed by San Diego at 11.3%, Palo Alto at 10.5%, Austin at 10.4%, and San Francisco at 10.1%. (alleywatch.com) The March numbers point to a venture market still writing its largest checks for artificial intelligence, especially where software is tied to aircraft, ships, and factory machines. The next test is whether that concentration holds once the mega-round effect fades and more ordinary months set the pace. (alleywatch.com, shield.ai, cnbc.com, businesswire.com)
