Musk's brain-computer company Neuralink's valuation soars, employees want to sell shares to cash out

According to Reuters, after Musk's brain-computer interface company Neuralink completed its first human trial, the company's valuation rose sharply, triggering a wave of internal employees selling stocks while the market is hot. People familiar with the matter revealed that some employees are actively preparing to sell their stocks.

For the startup Neuralink, stock options are an important means of attracting talent. However, because these stocks are not traded on the open market, employees must go through complex private market transactions if they want to sell them. Sources said Neuralink may launch a stock repurchase plan as early as next month to allow employees to cash out.

Since the launch of its first human trial in January this year, Neuralink's valuation has increased significantly. Although the relevant transaction volume is small and cannot accurately reflect the current valuation, the market generally believes that the company's valuation has doubled to US$8 billion.
