US stocks end higher as CoreWeave results ease AI spending worries

[NEW YORK] US stocks closed higher on Wednesday (Nov 11), with the S&P 500 and the Nasdaq each rallying more than 1 per cent as earnings from neocloud firm CoreWeave cooled investor concerns about the durability of the AI trade, while Nvidia stabilised after two straight sessions of sharp declines.

Battered CoreWeave shares surged 24.7 per cent, their biggest daily percentage jump in more than three months, to close at the highest level in two weeks.

The company said it would become profitable in the first half of 2028 on an adjusted basis, seeking to reassure investors that strong demand and customer commitments could support its debt-fuelled expansion.

Sentiment improved across AI infrastructure stocks, as Nebius Group surged 15.4 per cent and Applied Digital shot up 7.4 per cent.

Nvidia advanced after shedding about US$430 billion of market capitalization in the previous two sessions as investors worried ​about CEO Jensen Huang’s relationship with a businesswoman alleged to be a Chinese spy.

Equities have been volatile in recent days. Investors have expressed concerns about more regulation in the AI space after sweeping Democratic victories in the US midterm elections last week. That, and worries about Nvidia’s leadership, pressured one of the biggest pillars of the current bull market.
