Elon Musk’s brain-computer interface company Neuralink has raised $600 million in a new funding round that values the startup at $9 billion before the injection of fresh capital, according to people familiar with the matter.
This marks a significant leap from the company’s last valuation of $3.5 billion in late 2023, as reported by PitchBook. The sharp increase follows Neuralink’s recent progress in human trials, including the successful implantation of brain chips in three individuals. One of the most high-profile cases involved a non-verbal man with ALS in Arizona who, in a video posted on Musk’s social media platform X, demonstrated the ability to communicate using the implant.
The latest round exceeded expectations; Bloomberg reported in April that Neuralink was initially seeking $500 million at a valuation of $8.5 billion. Jared Birchall, Neuralink’s CEO and longtime head of Musk’s family office, declined to comment on the deal.
While Neuralink remains one of Musk’s smaller ventures, its valuation surge mirrors the broader expansion of Musk’s business empire. SpaceX, his aerospace giant, was valued at $180 billion in a fundraising round last August and hit $350 billion on the secondary market by the end of 2024. Meanwhile, Musk’s artificial intelligence startup xAI merged with X earlier this year, creating a combined entity worth $113 billion. xAI alone had been valued at $80 billion prior to the merger.
Though Neuralink’s technology is not yet ready for commercial release, more volunteers are joining its clinical trials. The company’s device, designed to restore communication and motor function through direct brain signals, has drawn both excitement and scrutiny from the scientific community. The MIT Technology Review noted earlier this year that despite the growing pool of patients, widespread availability remains a distant goal.
Musk himself has signaled a renewed focus on his core ventures. In a post on X this week, he wrote: “Back to spending 24/7 at work and sleeping in conference/server/factory rooms. I must be super focused on 𝕏/xAI and Tesla (plus Starship launch next week), as we have critical technologies rolling out.”
As Neuralink secures new funding and garners attention for its pioneering work, the startup faces mounting pressure to prove that its ambitious vision—merging the human brain with advanced technology—can translate into scalable, safe, and transformative medical applications.
