Stock Market Today: Dow Jumps 950 Points as Oil Slide Calms Inflation Fears; Nvidia Plunges on CEO Probe

New York, Nov. 9, 2026 — U.S. stocks roared back on Monday, with the Dow Jones Industrial Average surging nearly 1,000 points as a sharp drop in oil prices eased inflation jitters and investors piled back into beaten-down AI and semiconductor shares, even as Nvidia tumbled to a seven-month low on a scandal surrounding its CEO.

The Dow Jones Industrial Average climbed 953.53 points, or 1.86%, to 52,239.26 in late-morning trading . The S&P 500 jumped 2.05% to 7,528.39, while the Nasdaq Composite surged 2.34% to 25,155.62 . The rally added roughly $1.5 trillion in market value, marking Wall Street’s best day since April .

Why Did the Stock Market Rally Today?

1. Oil prices fell as Trump downplayed Iran strikes. President Trump said Sunday he was highly unlikely to order fresh attacks on Iran as long as negotiations to end the conflict progress. Brent crude fell 2% to $96.29 per barrel, easing fears that energy costs would keep inflation elevated . The move provided immediate relief to a market rattled by last week’s AI-led selloff.

2. Brokerages called the AI rout overdone. Morgan Stanley and UBS both argued that last week’s plunge in AI stocks—triggered by fears that Democratic midterm victories would bring harsh data center regulation—was excessive. They noted that extreme regulatory outcomes are unlikely to materialize under a Democrat-controlled Congress . The reassurances sparked a broad dip-buying wave.

3. Semiconductor stocks staged a violent rebound. The Philadelphia Semiconductor Index jumped 6% after suffering its worst week since March 2025 . AMD surged more than 12% after Oppenheimer upgraded the stock to Outperform with a $600 price target, citing its growing AI business and Google Cloud partnership . Marvell Technology and Broadcom each rose over 8%, while Intel and Qualcomm gained more than 4% .

Why Did Nvidia Plunge?

Nvidia was the sole loser in the semiconductor index, falling 6.2% to its lowest level since April . The drop followed an internal investigation into whether CEO Jensen Huang had been targeted by a foreign intelligence effort. Reports indicated Huang acknowledged an extramarital relationship with a Singapore-based business executive suspected of gathering information for China. The board has launched an independent probe, and Huang has said he will cooperate .

Despite Nvidia’s decline, the broader market’s strength overwhelmed the drag. Other megacap technology names rallied: Microsoft gained over 3%, Alphabet, Meta, and Amazon rose between 2% and 5%, and Tesla climbed 5.5% .

Which Other Stocks Moved?

Constellation Energy surged 8% after its adjusted third-quarter profit surpassed expectations, benefiting from structural demand from energy-intensive data centers . KKR rose 2.3% after reporting record quarterly profit . Barrick Mining advanced approximately 4% on stronger-than-expected earnings driven by gold strength .

What’s Next for Investors?

All eyes are on Tuesday’s October Consumer Price Index report, which will be the first major inflation reading since the midterm elections. Economists expect CPI to rise 3.9% year-over-year, up from the prior pace, driven largely by elevated energy costs . A hotter-than-expected print could revive fears of a December Fed rate hike—markets currently price roughly an 80% probability of a quarter-point increase following Friday’s blowout jobs report .

Earnings from CoreWeave, Applied Materials, and Cisco Systems this week will also test whether AI infrastructure spending is translating into profits, a question that has grown more urgent after the sector’s recent volatility .
