TL;DR

US stock indices closed higher on Friday, September 25, 2026, locking in weekly gains despite a sharp rise in Treasury yields. The Dow Jones Industrial Average led the rally, jumping 479 points to 51,829, while the S&P 500 and Nasdaq Composite each rose approximately 0.5%. Microsoft shares surged over 3% following the launch of new Copilot AI features, driving much of the market's strength. The 10-year Treasury yield climbed to 5.18%, near a 19-year high, yet equities remained resilient. Falling oil prices, driven by hopes of a US-Iran deal to reopen the Strait of Hormuz, helped ease inflation concerns. President Trump and Chinese President Xi Jinping concluded meetings and announced an AI summit for November. Key movers included a 21% jump in Akamai Technologies and a 10% rise in People Incorporated, while Zscaler fell 8.6% after a leadership change. Investors now look to upcoming earnings from Micron, Nike, and Carnival Corp.

Key points

  • Dow Jones Industrial Average closed at 51,829, up 479 points (0.9%).
  • S&P 500 closed at 7,743, up 39 points (0.5%).
  • Nasdaq Composite closed at 27,069, up 129 points (0.5%).
  • 10-year Treasury yield rose to 5.18%, near a 19-year high.
  • Microsoft shares rose over 3% after unveiling new Copilot AI features.
  • Brent crude oil fell about 5% for the week amid US-Iran diplomatic talks.

Background

This week's market resilience follows a volatile period where rising oil prices and bond yields had weighed on equities in late September. Earlier in the month, the S&P 500 had hit record highs on easing inflation data, but recent sessions saw pullbacks due to geopolitical tensions and higher borrowing costs. The current rally marks a shift as investors prioritize corporate earnings and AI developments over immediate bond market volatility.

How outlets are covering it

MarketWatch and Proactive Investors both highlight the disconnect between surging bond yields and rising stock prices, noting that falling oil prices helped offset inflation fears. Moomoo emphasizes the specific impact of Microsoft and Caterpillar on the Dow's gains. Yahoo Finance provides precise closing figures for the major indices. Proactive Investors offers the broadest view, detailing specific corporate movers like Akamai and Zscaler, as well as geopolitical developments involving US-China relations and the Strait of Hormuz. While all sources agree on the positive close, they differ in emphasis: Moomoo focuses on individual stock drivers, while Proactive Investors contextualizes the move within broader geopolitical and macroeconomic trends.

Why it matters

The ability of US equities to rise despite record-high Treasury yields signals strong investor confidence in corporate earnings and AI-driven growth. The decline in oil prices due to potential US-Iran diplomatic breakthroughs reduces inflationary pressure, potentially influencing Federal Reserve policy expectations. The surge in Microsoft and other tech stocks indicates continued market appetite for artificial intelligence innovations, even in a high-rate environment.

What to watch

Investors will closely watch earnings reports from Micron, Carnival Corp, and Nike next week for signals on consumer spending and economic resilience. Wells Fargo analysts expect consumer spending to rise 0.8% in August. The market will also monitor the 10-year Treasury yield for further volatility and watch for developments in US-Iran negotiations regarding the Strait of Hormuz. An AI summit between the US and China is scheduled for November in Shenzhen.
