NVIDIA's stock price hit a record high for the first time since May. After two months of selling off that resulted in a market value loss of over $1 trillion, investors have flocked back to the stock.

The stock price of this company, which has the highest global market value among listed companies, rose by 2.9% on Friday, representing a cumulative rebound of nearly 25% from its low point at the end of July. At that time, concerns about the prospects of artificial intelligence once put pressure on NVIDIA's stock price.

In recent weeks, the market has been optimistic that intelligents such as Muse of Meta Platforms and AI could drive an increase in semiconductor demand, providing support for the rise in NVIDIA's stock price. After NVIDIA announced on Monday that it would increase its share repurchase plan by a record $150 billion, the stock price was further boosted.

Before NVIDIA's rebound this time, market sentiment towards the prospects of the AI industry had changed rapidly over the past few months. This included concerns regarding whether it was reasonable for companies to spend trillions of dollars on building AI infrastructure, as well as potential security risks that this technology might pose to humanity.

A chip developer headquartered in Santa Clara, California, released a new dual-layer AI security system on Monday, aimed at preventing AI intelligents from getting out of control. NVIDIA stated that this new system is capable of preventing recent incidents where OpenAI's AI models led to Hugging Face intrusions.

NVIDIA's stock price has risen by about 27% so far this year and is on track to achieve double-digit growth for the fourth consecutive year. The company's current market value is approximately $5.7 trillion, with less than $300 billion remaining before it becomes the first company in history to reach a market value of $6 trillion.
