Apptronik, a fast-growing startup that makes artificial intelligence-powered humanoid robots, has secured about $520 million in a new funding round that values the company at more than $5.5 billion, around three times its valuation from its initial Series A raise last year. The funding round was led by existing investors including Google, Mercedes-Benz Group AG and B Capital, along with new investors AT&T Ventures, John Deere & Co. and the Qatar Investment Authority. This investment is an extension of a $415 million fundraise in February 2025. The company said it received substantial inbound investor interest after the first round, leading it to open the new extension at three times the valuation. The funding comes at a time when investors have been committing billions of dollars to humanoid robotics startups, including Figure AI and Dexterity, betting that advances in AI will speed up commercial adoption.
