Key Highlights

● Oracle's Opower platform hit a record 1 gigawatt of peak Demand reduction.

Oracle (NYSE:ORCL) rallied on Wednesday, trading at $128.38 during the session as investors rotated back into companies building the backbone of artificial intelligence. Oracle finished among the strong performers in the S&P 500.

Oracle is best known for its database software, but in recent years it has bet heavily on cloud infrastructure, building out data centers to rent computing capacity to AI developers and large enterprises. That push has made the stock a high-profile AI infrastructure play, and it tends to move sharply with shifting views about the durability of AI spending.

The broader AI build-out group rallied together on Wednesday. Dell (NYSE:DELL) rocketed, Super Micro Computer (NASDAQ:SMCI) surged and chipmakers from AMD (NASDAQ:AMD) to Micron (NASDAQ:MU) climbed sharply, while optical networking names such as Coherent (NYSE:COHR) and Lumentum (NASDAQ:LITE) soared.

CoreWeave's read-through

The day's catalyst was CoreWeave (NASDAQ:CRWV), the AI cloud provider that, like Oracle, rents out large clusters of GPU servers. CoreWeave reported third-quarter revenue of $3.66 billion, more than double a year earlier and ahead of estimates near $3.54 billion to $3.55 billion. It raised its 2026 revenue outlook to $13.0 billion to $13.3 billion, pointed to a Backlog of about $132.5 billion and guided adjusted Operating Income to $1.275 billion to $1.375 billion, well above the $1.07 billion consensus.

"Demand for compute is growing faster than the capacity to deliver that infrastructure," CEO Michael Intrator said on the earnings call.

For Oracle, a peer in renting AI computing capacity, those comments eased worries stoked during last week's AI-capex scare that customers might pull back. The company also had company-specific news: Oracle's Opower utilities platform hit a record 1 gigawatt of peak demand reduction, a measure of how much electricity use utilities shifted away from peak hours using its tools.

A tech-led rally

Technology was the best-performing sector in the S&P 500 by a wide margin. The S&P 500 rose 98.45 points to 7,619.38, the Nasdaq Composite gained 400.31 points to 25,466.19 and the Dow Jones Industrial Average added 254.60 points to 52,486.49. The Russell 2000 climbed 24.88 points to 2,846.26, and the VIX slid to 17.49.

The Bond Market was closed for Veterans Day, so there was no fresh Treasury trading. Rates remained in focus after Tuesday's hotter-than-expected October consumer price report left a December Federal Reserve rate hike seen as nearly fully priced. That matters for capital-intensive businesses like data-center operators, which rely on borrowing to fund expansion.

Not every big tech name joined in. Microsoft (NASDAQ:MSFT), a major cloud rival, fell for a second straight day after Anthropic launched new productivity tools, while Amazon (NASDAQ:AMZN) and Meta (NASDAQ:META) also lagged.

Nebius, Cisco and Anthropic Could Sway AI Names

The evening brought fresh uncertainty. Nvidia (NASDAQ:NVDA), the leading supplier of AI chips that Fill cloud data centers, fell in after-hours trading following newspaper reports about its leadership, and Nasdaq-100 futures slipped. That could test AI infrastructure names when trading resumes Thursday.

Thursday's calendar includes Nebius (NASDAQ:NBIS), another AI cloud provider, reporting before the open, with consensus revenue of $3.35 billion. Cisco (NASDAQ:CSCO) and Applied Materials (NASDAQ:AMAT) report after the bell, and weekly jobless claims are due at 8:30 a.m. Eastern time. October producer prices arrive Friday.

Further out, Nvidia's November 17 report and Anthropic's expected initial public offering next week could shape views on AI demand, while the Federal Reserve meets December 8 and 9.
