What We Know About the Nasdaq's Record Close Monday

The Nasdaq Composite closed at an all-time high Monday, up 2.2%, after chip stocks and Meta Platforms led a rally tied to falling oil prices and bond yields, according to NBC News. The Nasdaq 100 posted its best single-day performance since early August. The S&P 500 rose 1.5%, also its strongest day since early last month, and the Dow Jones Industrial Average added more than 360 points, or 0.7%.

Which stocks drove the rally?

ARM Holdings shares spiked 17%, and Intel rose 12%, ranking among the Nasdaq's top performers, NBC News reported. AMD climbed nearly 10% and, in doing so, pushed the chipmaker's market valuation past $1 trillion for the first time. Meta Platforms rose 11.4%, adding nearly $200 billion in market value on optimism tied to its AI ambitions and its recently released Muse AI assistant — the company's best one-day stock performance since the April 2025 tariff selloff, per NBC News.

The buying extended beyond tech. Moderna shares rose 12%. Paramount Skydance and Warner Bros. Discovery each jumped more than 10% after the two companies reached a deal with state attorneys general that clears a path toward closing their merger, NBC News reported.

Why did oil prices and bond yields fall?

The rally traced back to a weekend report from Fox News Channel's Trey Yingst, who said President Donald Trump told him he would "possibly be open to meeting with Iranian President Pezeshkian" during this week's United Nations General Assembly in New York, according to NBC News. The prospect of renewed U.S.-Iran talks raised investor hopes for a resumption of oil traffic through the Strait of Hormuz.

Brent crude closed Monday at $100.34 a barrel, down 3.4% for the day, while U.S. crude fell 4.5% to $95.78, NBC News reported. Bloomberg News reports cited by NBC News, citing satellite imagery of oil supertankers, also pointed to an increase in Saudi Arabia's oil flows, adding further downward pressure on prices.

What does AMD's $1 trillion valuation signal?

AMD's move into trillion-dollar territory places it alongside a small group of U.S. companies at that valuation threshold, underscoring how far chipmaker stocks have run on AI-driven demand. NBC News did not report AMD's exact closing share price or market-cap figure beyond the trillion-dollar threshold.
