The broad S&P 500 index rose 0.6 percent and reached a new high level. Nasdaq's technology-heavy composite index also reached a new record level after climbing 1.1 percent. The Dow Jones industrial index traded sideways.
It was different the previous day, when the broad index fell 0.4 percent and thus broke a seven-day long upward trend. Then it was the software giant Oracle's share that led the decline, which also fueled concerns that an AI bubble may be around the corner.
But on Wednesday, it was instead Nvidia that acted as the locomotive. The share rose 2.2 percent after CEO Jensen Huang said that the chip giant had seen increased demand for AI in recent months.
AMD also continued to rush, up 11.4 percent. On Monday, the share rushed as much as 23.7 percent after it became known that the chip manufacturer had entered into an agreement with Open AI.
The protocol from the September meeting in the US central bank Federal Reserve (Fed) was published on Wednesday. The members were in agreement on the first interest rate hike of the year, but according to the protocol, they were disagreed on how many further cuts that may be considered before the end of the year.
However, trading on the stock exchange was not noticeably affected by the protocol.
Nor does the shutdown of the US government apparatus, which is in its second week, seem to affect the stock market mood.
