US STOCKS-S&P 500, Nasdaq rise as CoreWeave results ease AI spending worries

The S&P 500 and ‌the ​tech-heavy Nasdaq climbed on Wednesday after neocloud firm CoreWeave's strong earnings calmed investor jitters about bloated AI expenditure. CoreWeave's shares jumped 12.7%after the battered company said it would become profitable in the first half of 2028, on an adjusted basis, as it sought ‌to reassure investors that strong demand and customer commitments could support its debt-fueled expansion.

"CoreWeave was emblematic of the shift from viewing all AI investments as good investments to taking a more sober look at the returns on the billions of dollars being spent on AI. The earnings report helped ease some of those concerns," said Steve Sosnick, chief market analyst at ‌Interactive Brokers. The results boosted sentiment across AI infrastructure stocks, with Nebius Group and Applied Digital rising 12.5% and 5.2%, respectively.

Nvidia edged 2.4% higher after shedding about $430 billion in the ‌last two sessions as questions about CEO Jensen Huang's relationship with a businesswoman alleged to be a Chinese spy roiled markets.

Data storage firms Seagate Technology and Western Digital also traded higher. Equities whipsawed this week, with concerns over slower data center deployment, higher interest rates and Nvidia's troubles pitted against the appetite ⁠to buy ​the dip.
