Neuralink, the brain implant startup founded by Elon Musk, is now worth nearly $5 billion. The company's valuation has increased significantly in recent months, following its announcement that it had received approval from US regulators to conduct a human trial on its brain chip.

Neuralink was founded in 2016 with the goal of developing implantable brain-computer interfaces (BCIs). These devices would allow people to control computers and other devices with their thoughts. The company has made significant progress in developing its technology, and it is now one of the leading companies in the BCI field.

In May 2023, Neuralink announced that it had received approval from the US Food and Drug Administration (FDA) to conduct a human trial on its brain chip. The trial will involve implanting the chip in patients with severe neurological conditions, such as paralysis or epilepsy.

The FDA approval is a major milestone for Neuralink, and it is likely to lead to further investment in the company. The company is now valued at nearly $5 billion, and it is seen as one of the most promising startups in the tech industry.

Neuralink's technology has the potential to revolutionize the way we interact with computers and other devices. The company's success could lead to a future where people are able to control their devices with their thoughts, and where BCIs are used to treat a variety of neurological conditions.
