Nvidia has surged 20% in seven days, with its market value approaching the $6 trillion mark!

```

Nvidia's stock price continued to rise on Thursday, extending the seven-day rally over which it has gained 20% in total, highlighting the continued influx of investors into chip stocks benefiting from the massive capital expenditures in artificial intelligence.

On Thursday, Nvidia's stock rose as much as 4.7% to $236.47, raising its market value by over $900 billion and pushing it closer to the $6 trillion mark—a valuation no company has yet reached.

This latest rally is a clear sign of investors concentrating their bets on AI winners, with semiconductors at the core of this wave. This week, Nvidia CEO Jensen Huang joined former US President Trump's China visit delegation as a "last-minute addition."

The Philadelphia Semiconductor Index has surged nearly 70% since the end of March, with companies like Intel, Micron Technology, AMD, and Broadcom all recording substantial gains in their stock prices.

However, the magnitude of this rally has sparked concerns among some market observers, who believe the US stock market is being pushed up by an AI bubble that could burst at any time. According to Bloomberg data, just Nvidia and Micron have contributed more than 30% of the S&P 500’s gains so far this year.

Thursday also saw the IPO of AI chipmaker Cerebras Systems, the largest IPO so far this year. Demand was extremely strong, and the stock soared as much as 109% after listing.
