Neuralink is one of a growing number of ventures developing brain-computer interfaces, with the near-term goal of helping paralysed people interact more fully with the world through electronic devices. Last month, rival Paradromics Inc. tested its brain implant in its first patient.
Neuralink Corp., Elon Musk’s brain chip company, raised US$650 million ($835.3 million) in a Series E funding round.
At least 11 investment firms, including ARK Investment Management, Founders Fund and Sequoia Capital, participated in the round, according to a statement released Monday. Since the previous funding round in August 2023, the company said it has enrolled five patients with severe paralysis and announced a clinical trial in Abu Dhabi on May 14.
