The 19 Largest Global Startup Funding Rounds of July 2026

July 2026 saw a string of headline-grabbing startup financings, dominated by nine-figure rounds across AI, quantum computing, semiconductors, biopharma and energy. The 19 largest rounds that month included a group of blockbuster financings: Chai Discovery and Meshy AI each raised $400.0M; AdvanCell closed $315.0M; Antares took $370.0M; and several companies — Oratomic, Walden Robotics, Xsight Labs and Etched — each reported $300.0M rounds. Strategic and institutional backers participating across these deals ranged from OpenAI, Intel Capital and Eli Lilly to Toyota Ventures, Bain Capital Life Sciences and SK Hynix.

"a month defined by scale, ambition, and the accelerating convergence of artificial intelligence with every sector from defense and energy to healthcare and quantum computing."

The list highlights both deep-tech infrastructure plays and fast-moving AI platform companies. Chai Discovery, based in San Francisco and founded in 2024 by Jack Dent, Jacques Boitreaud, Joshua Meier and Matthew McPartlon, closed a $400.0M Series C that lifts its total equity funding to $630.0M. The round attracted heavyweight backers including OpenAI, Menlo Ventures, General Catalyst, Index Ventures and Sequoia Capital, underscoring investor appetite for AI applied to protein engineering and molecular design.

Also at $400.0M, Meshy AI — founded by Ethan Hu in 2021 and based in Sunnyvale — raised a Series B to expand its AI platform for generating and editing 3D models from text and image prompts. Its investor roster includes BAI capital, Granite Asia, HSG, IDG Capital, Matrix Partners China, Monolith Capital and Source Code Capital, bringing Meshy AI’s total equity funding to $450.0M.

Several hardware and semiconductor companies drew massive capital as infrastructure demand for AI and data centers continues. Etched, founded in 2022 by Chris Zhu, Gavin Uberti and Robert Wachen, completed a $300.0M Series C and has now raised $925.4M in total equity; backers on the round include Andreessen Horowitz, Sequoia Capital and SK Hynix. Xsight Labs of Kiryat Gat, founded in 2017 by Erez Shaizaf, Gal Malach and Guy Koren, closed a $300.0M Series E, bringing total equity to $400.0M with investors such as Valor Equity Partners, Battery Ventures, T. Rowe Price and Intel Capital.

• Oratomic (South Pasadena) — $300.0M Series A; developing neutral-atom quantum hardware; total equity now $310.0M; investors include General Catalyst, Index Ventures, Khosla Ventures and ARCH Venture Partners.
• Walden Robotics (Cambridge) — $300.0M seed; building wheeled, two-armed semi-humanoid robots for logistics and manufacturing; investors include Menlo Ventures, NVIDIA, The Boeing Company and Toyota Ventures.
• AdvanCell (Sydney) — $315.0M Series D; focused on targeted alpha radiopharmaceutical therapies; backers include Eli Lilly, Alpha Wave Global and Bain Capital Life Sciences; total equity now $439.5M.
• Antares (Los Angeles) — $370.0M Series C; transportable nuclear fission microreactors for terrestrial and space applications; founders Jordan Bramble and Julia DeWahl; total equity $471.0M.

The investor mix on these rounds — from corporate venture arms like Intel Capital, SK Hynix and Toyota Ventures to large funds such as Bain Capital Life Sciences, Sequoia and T. Rowe Price — signals continued conviction in capital-intensive startups that promise durable infrastructure or platform advantage. While valuations were not disclosed for every deal, the aggregate pattern points to concentrated capital flows into foundational technologies: AI models and tooling, next-generation semiconductors, quantum hardware, robotics and specialty therapeutics.

Looking ahead, the depth of these syndicates and the participation of both strategic corporate investors and top-tier VCs suggest follow-on capital will remain accessible for companies that can demonstrate rapid technical progress or early commercial traction. For startups targeting compute infrastructure, advanced materials, or biologics, July’s rounds may set a new baseline for the cash and partnerships needed to scale complex technology bets.
