All three major US stock indexes rose Wednesday after AI cloud computing company CoreWeave posted a surprise earnings beat, with semiconductor stocks — led by a nearly 12 percent surge in Micron — driving a broad technology rebound.

The Dow Jones Industrial Average closed up 254.60 points, or 0.49 percent, at 52,486.49 on the New York Stock Exchange Wednesday (local time).

The S&P 500 gained 98.45 points, or 1.31 percent, to finish at 7,619.38, while the NASDAQ Composite rose 400.31 points, or 1.60 percent, to close at 25,466.19.

CoreWeave's earnings drove the day's rally. The AI cloud company reported third-quarter results after Wednesday's closing bell that exceeded market expectations. It also announced plans to issue no additional unsecured parent-level bonds through 2027 and to cap new fundraising over the same period at less than $5 billion.

The announcement eased concerns that had weighed on markets over the heavy debt burden tied to expanding AI data center investment, helping restore investor confidence. CoreWeave's share price surged 24.7 percent on the day.

The improved AI sentiment drew buyers into semiconductor stocks, which had suffered steep losses in recent sessions. The Philadelphia Semiconductor Index jumped 5.7 percent from the previous session.

Seo Sang-young, a managing director at Mirae Asset Securities, said US markets surged, centered on AI and semiconductor stocks, following CoreWeave's earnings and its announcement of an improved financing structure. "Credit risk, which had emerged as a key threat to the AI industry recently, eased somewhat, concentrating rebound buying in oversold names," Seo said.

Micron, the US memory chipmaker, closed up 11.9 percent at $811.30. Its market capitalization expanded by $97.5 billion in a single session to reach $917.9 billion. SanDisk and Western Digital also surged, gaining 13.7 percent and 8.3 percent, respectively.

Nvidia, which had fallen sharply for two consecutive sessions amid allegations surrounding CEO Jensen Huang's personal life, rebounded 2.9 percent.

Among major technology stocks, results were mixed. Microsoft fell 2.3 percent, Amazon dropped 1.7 percent and Meta Platforms declined 2.0 percent, while Alphabet rose 2.1 percent.
