Neuralink, the brain-computer interface startup led by Elon Musk, has raised $650 million in a recent funding round, bringing its valuation to approximately $9 billion. Investors in this round include ARK Invest and Sequoia Capital. The company, which began human trials in 2024, has implanted its chip in paralysis patients who have demonstrated the ability to control computers using their thoughts. Neuralink is considered the most well-funded company in the brain-computer interface sector, which has seen multiple firms secure substantial venture capital. Additionally, other startups such as Brooklyn Health are advancing neuroscience clinical trials with innovative platforms like Willis, which standardizes behavioral assessments.
