November 13, 2026 · U.S. market close
U.S. stocks posted their first winning week since early October, but the rebound faced two major challenges: the sudden resignation of Nvidia CEO Jensen Huang and inflation data that reinforced expectations of higher interest rates.
Meanwhile, strong AI infrastructure demand and Anthropic’s upcoming IPO underscored the industry’s enormous growth potential, and the financial risks that come with it.
The week in review
| Index | Friday close | Friday change | Weekly change |
|---|---|---|---|
| S&P 500 | 7,561.67 | −0.4% | +2.5% |
| Nasdaq Composite | 25,136.27 | −0.9% | +2.3% |
| Dow Jones Industrial Average | 52,347.55 | +0.1% | +2.1% |
| Russell 2000 | 2,790.49 | −0.3% | +1.3% |
The S&P 500 closed at 7,561.67 and is up 10.5% for the year. It was the index’s first winning week since early October and its biggest weekly gain since August, ending four-week losing streaks for both the S&P 500 and the Nasdaq. AP · AP · IBTimes
Most of the gain came Monday, when the S&P 500 jumped 2.35%, its best day since April, as oil prices fell. Hotter-than-expected inflation data pulled stocks down 0.4% Tuesday, AI stocks rebounded Wednesday with a 1.3% gain, and Nvidia’s leadership turmoil weighed on tech Thursday and Friday.

The 10-year Treasury yield rose to 5.15% on Friday, from 4.86% a week earlier, adding pressure on rate-sensitive growth stocks. AP · Krilogy
Why it matters: The broader market showed resilience, but rising borrowing costs and concentrated weakness in technology remain important risks.
Fed and economic developments
Inflation dominated the economic calendar.
- Consumer inflation: October CPI rose 0.4% from September, and core CPI rose 0.3%; both were above forecasts. The BLS did not publish a 12-month rate because the government shutdown prevented it from collecting October 2025 data. CNBC · BLS
- Producer inflation: October PPI rose 0.3% for the month and 6.5% over 12 months, the largest annual increase since November 2022. BLS
- Pipeline pressures: Prices for final demand goods rose 10.2% over 12 months, the largest increase since October 2022, suggesting businesses still face substantial input-cost increases. BLS · CNBC
Fed funds futures fully price at least a quarter-point rate hike at the Fed’s December 8–9 meeting. The open question is the size: after the CPI report, traders put roughly an 11% chance on a half-point increase, according to CME FedWatch as reported by Reuters on Nov. 11. These probabilities move with market pricing; they are not a policy commitment. CNBC · Reuters
Why it matters: Persistent inflation can keep Treasury yields elevated, increasing financing costs and making high-growth stock valuations harder to sustain.
Major market movers
Nvidia: Leadership uncertainty shakes the AI sector. Jensen Huang resigned as Nvidia’s CEO, president and board member on November 12. CFO Colette Kress became interim CEO while the board searches for a permanent replacement. NVIDIA
The departure followed reporting about Huang’s personal relationships and an independent board investigation. The board has not announced any findings, and the allegations involving foreign intelligence have not been established. NVIDIA board statement
Nvidia shares fell 12.8% for the week to $162.85, weighing on semiconductor stocks ahead of the company’s November 17 earnings report. TheStreet · Yahoo Finance
CoreWeave: Rapid growth meets enormous financing costs. CoreWeave reported third-quarter revenue of $3.66 billion, up 168% year over year, and a backlog of about $132.5 billion. However, it also reported a $709 million net loss and $846 million in net interest expense. Its full-year capital spending outlook stands at $37 billion to $39 billion. CoreWeave · TradingKey
Why it matters: CoreWeave illustrates the central tension in AI infrastructure: extraordinary customer demand alongside enormous capital requirements.
AI and technology: Anthropic approaches the public market
Anthropic set an IPO price range of $70 to $78 per share, implying a fully diluted valuation of up to about $1.4 trillion at the top of the range. The company plans to offer 825 million shares and has arranged a separate $26 billion private placement with major technology companies. Trading is expected around November 19 under the proposed Nasdaq ticker ANT, although the final pricing and listing date remain subject to change. Decrypt · CNBC
The offering could become an important test of institutional demand for AI investments.
Why it matters: Investors will be evaluating whether rapid revenue growth justifies enormous valuations, especially when AI companies face significant computing commitments and ongoing losses.
Regulation and infrastructure
The Senate voted 73-25 on Monday to advance the Bipartisan American Affordability and Jobs Act, a permitting overhaul that would speed approvals for power plants, transmission lines and other infrastructure while requiring large data centers to pay more of the cost of grid upgrades. The vote opened debate; the bill still needs final Senate passage and House approval before it can become law. The Hill · Reuters via The Spokesman-Review
The broader debate around data-center expansion also continues, including concerns about electricity costs, local resources and regulatory oversight.
Why it matters: Access to power and infrastructure permits is increasingly important to AI growth, alongside chips and computing capacity.

The most important events are Nvidia’s earnings and Anthropic’s anticipated IPO. Both could influence sentiment across semiconductor, cloud infrastructure and AI-related stocks.
Market Organized takeaway
The AI boom remains powerful, but the market is increasingly distinguishing technological progress from investment returns. Nvidia’s leadership uncertainty demonstrates how company-specific developments can influence an entire industry. CoreWeave’s results show that strong demand does not automatically translate into bottom-line profitability. And Anthropic’s IPO will provide another test of how investors value companies with rapid growth, substantial losses and long-term infrastructure commitments.
Meanwhile, persistent inflation and elevated Treasury yields remain challenges for growth-stock valuations.
Bottom line: The market recovered this week, but investors still face a difficult combination of AI-related uncertainty, expensive financing and persistent inflation. The next phase of the rally may depend less on enthusiasm and more on demonstrated earnings, cash flow and execution. These are scenarios to monitor, not forecasts to treat as settled.
Stay sharp, stay organized.
