Nvidia became the first company to reach 4 trillion in market value on Wednesday, a new milestone in Wall Street's bet that artificial intelligence will transform the economy. Shortly after the stock market opened, Nvidia vaulted as high as 164.42, giving it a valuation above 4 trillion. The stock subsequently edged lower, ending just under the record threshold. "The market has an incredible certainty that AI is the future," said Steve Sosnick of Interactive Brokers. "Nvidia is certainly the company most positioned to benefit from that gold rush."

Nvidia has notched a market capitalisation of 4 trillion, making it the first public company in the world to reach the milestone and solidifying its position as one of Wall Street's most-favoured stocks. On Wednesday, shares of the leading chip designer rose as much as 2.5 percent to an all-time high of 164, benefiting from the continuing surge in demand for artificial intelligence technologies. The stock's recent rally comes despite a sluggish start to the year, when the emergence of a Chinese discount artificial intelligence model developed by DeepSeek shook confidence in stocks linked to the sector. Nvidia achieved a 1 trillion market value for the first time in June 2023 and tripled it in about a year, faster than Apple and Microsoft, the only other United States firms with a market value of more than 3 trillion. Microsoft is the second-biggest US company, with a market capitalisation of 3.75 trillion.
