Nasdaq-100 futures fell Wednesday evening as Nvidia shares dropped in extended trading after reports involving Chief Executive Jensen Huang, CNBC said¹.

Futures tied to the Nasdaq-100 lost about 1%, S&P 500 futures fell about 0.4%, and Dow Jones Industrial Average futures were little changed, according to the network's live wrap¹.

CNBC said Nvidia was last down around 8% after hours and fell more than 7% after The Wall Street Journal reported that Nvidia's board was preparing to remove Huang¹.

The network said that news followed a New York Times report that Huang had an extramarital relationship with an executive at the company¹.

Nvidia did not provide a comment in the CNBC wrap¹.

In regular trading Wednesday, CNBC said the Dow rose nearly 255 points, or 0.5%, the S&P 500 advanced 1.3%, and the Nasdaq Composite jumped 1.6%, driven by a post-earnings advance in CoreWeave and a rebound in Nvidia¹.

Investors were weighing whether the artificial intelligence-driven rally has more room to run given recent weakness in Nvidia, CNBC said, while CoreWeave's results and raised revenue outlook reinforced a longer-term growth story heading into Thursday¹.

Sameer Samana of Wells Fargo Investment Institute told CNBC that stubborn inflation, further Federal Reserve rate increases, higher long-term interest rates, political change in Washington and AI and data-center regulation argued for staying selective rather than chasing the bounce¹.

Callie Cox of Plancorp told CNBC that tension between AI optimism and macroeconomic concerns could continue to weigh on sentiment¹.

CNBC said markets next look to Thursday's initial jobless claims at 8:30 a.m. ET and existing-home sales at 10 a.m. ET¹.
