Sand.ai Secures $200 Million in A+ Round Funding to Become a Unicorn

Video model company Sand.ai announced on November 5 that it has completed a $200 million A+ round of financing, led jointly by Cornerstone Capital and Wangsu Science & Technology, with participation from Shanghai State-owned Assets and Times Capital, among others. Existing investors such as Matrix Partners continued to increase their stakes. This marks the company's third round of financing completed in 2026, bringing the total financing amount to $300 million within 10 months, officially entering the unicorn ranks after this round of funding. Sand.ai was founded by former Microsoft Research Asia senior researcher Cao Yue, with its core product being the video generation foundational model MAGI series. The company open-sourced its video generation model MAGI-2 Preview, which features a trillion-parameter MoE architecture, in August 2026, with a total parameter count of 114 billion, activating approximately 6 billion parameters per generation. A larger parameter version, MAGI-2, will be officially released soon, and the funds from this round of financing will primarily be used for the research and development of video foundational models, training and inference infrastructure construction, product iteration, and global market expansion.
