S&P 500 Rises 1.3% as CoreWeave Soars About 25% and AI Stocks Rebound

Wall Street recovered on Wednesday, 11 November. AI and semiconductor stocks led the rebound after CoreWeave's quarterly results eased worries about AI spending. The S&P 500 rose about 1.3% to roughly 7,619, the Nasdaq Composite gained about 1.6% to around 25,466, and the Dow added about 0.5% to near 52,486. The Russell 2000 rose about 0.9%.

The bounce came one day after a hotter-than-expected October CPI report pushed stocks lower and raised the odds of a December Fed hike. The bond market was closed for Veterans Day, so stocks traded without new signals from Treasury yields.

What happened

• CoreWeave jumped about 24.7%, its best day since April 2025. The AI cloud provider reported Q3 revenue of about $3.66 billion, up 168% from a year earlier, and a contract backlog of about $132.5 billion. It also raised its full-year revenue guidance to $13.0–13.3 billion.
• Other neoclouds followed. Nebius rose about 15% and IREN about 6%.
• Every member of the Philadelphia Semiconductor Index closed higher, which shows how broad the AI rebound was.
• Apple hit another record, adding to the strength in mega-cap tech.
• Some analysts were cautious. UBS questioned whether one strong quarter is enough to rebuild confidence, and Bernstein kept an underperform rating. CoreWeave's heavy debt load and rising interest costs are still the main concern.

Why it matters for traders

• AI demand is still the market's main engine. CoreWeave buys large amounts of Nvidia hardware, so its guidance is read as a signal for the whole AI supply chain.
• Rates are the counterweight. Futures put the odds of a December Fed hike at around 87–92%. With the 10-year yield near 5%, high-valuation growth stocks remain sensitive to every inflation print.
• Squeeze risk works both ways. Stocks with heavy short interest, like CoreWeave, can rise 20% or more in a day on good news. They can fall just as fast if the next update disappoints.
• Index breadth was positive. The Russell 2000 and the Dow also rose, so the rally was not only about a few large tech stocks.

What to watch

1. Nvidia earnings on 17 November, the biggest test for the AI trade this month.
2. Treasury yields when bond trading resumes on Thursday, and whether the 10-year stays below 5%.
3. Fed speakers. Governor Waller has backed a December hike, and markets will watch for any talk of a 50 basis point move.
4. Follow-through in CoreWeave and its peers after such a large one-day move.
