Wall Street's main indexes opened higher on Thursday as AI bellwether Nvidia's upbeat forecast soothed concerns of cooling demand in the industry, though a jump in weekly jobless claims kept a check on gains.

While Nvidia delivered a surge in quarterly revenue, it said first-quarter margin would tighten as it ramps production of its new flagship AI chips.

Nvidia's forecast also helps allay doubts around a slowdown in spending on its hardware that emerged last month. The company reported quarterly results on Wednesday.

Nvidia's quarterly outlook on Wednesday suggested demand from Microsoft, Amazon and other heavyweight tech companies racing to build out AI infrastructure remains robust following last month's launch of Chinese startup DeepSeek's low-cost model that raised fears of overspending.
