September 25, 2026 · U.S. market close
Stocks finished a winning week as renewed AI enthusiasm outweighed sharply higher bond yields and oil prices, but the gains were concentrated in a narrow group of technology leaders.
Market snapshot
| Index | Friday change | Weekly change |
|---|---|---|

| Dow Jones Industrial Average | +0.93% | +0.3% |

A narrow rally beneath the headlines
Nine of the 11 S&P 500 sectors are negative so far in September, with only technology and energy higher, and the equal-weight S&P 500 was down about 4% for the month through Thursday. In other words, the indexes look healthier than the average stock because AI and mega-cap technology are carrying an unusually large share of the load. Reuters (via Yahoo Finance) · CNN
Yields, oil and the Fed
The 10-year Treasury yield touched 5.22% on Friday, near its highest level since 2007, before settling around 5.15%. The 30-year yield peaked at 5.53%, its highest since 2004. Brent crude’s nearby contract stayed above $100 a barrel, ending near $106, while U.S. crude ended near $92.60. AP · CNN · Investing.com Brent · Investing.com WTI
Fed funds futures implied about a two-in-three chance (66.6%) of another 25-basis-point hike at the October 27–28 meeting, according to Investing.com’s Fed Rate Monitor late Friday. These probabilities move with market pricing; they are not a policy commitment. Investing.com Fed Rate Monitor · Federal Reserve calendar
My interpretation: Yields and oil remain the two biggest threats to equity valuations. Both are now pressing at levels the market has not had to absorb in years.
AI had another major week
Microsoft rallied more than 3% Friday after unveiling a revamped Copilot with a coding tool and always-on AI agents. Microsoft · BNN Bloomberg
Akamai Technologies rose after announcing a seven-year, $11.6 billion cloud-infrastructure agreement with Anthropic, though the stock gave back much of a roughly 20% premarket gain during Friday’s session. Akamai · TechCrunch · Motley Fool
Meta Platforms gained about 13% for the week as investors embraced Muse, its personal AI agent, even after a roughly 3% drop on Friday. Advanced Micro Devices briefly topped $1 trillion in market value for the first time on Monday, September 21. Meta · Forbes · Yahoo Finance · Quartz
Regulation and policy
On September 17, the SEC granted a five-year “innovation exemption” allowing tokenized stocks to trade on qualifying venues, its latest step toward a more permissive framework for digital assets and tokenized securities. SEC · CoinDesk
Separately, during September 21 talks with China, the U.S. proposed a mechanism for notifying each other about significant AI incidents. That is a proposal under discussion, not an agreement, an important distinction. AP (via SecurityWeek) · Forbes
What to watch next week
- Tuesday, Sept. 29: JOLTS job openings and Conference Board consumer confidence.
- Wednesday, Sept. 30: August PCE inflation, the third estimate of second-quarter GDP, and Micron earnings after the close.
- Thursday, Oct. 1: ISM manufacturing.
- Friday, Oct. 2: the September jobs report. The consensus expects roughly 100,000 new jobs and a 4.2% unemployment rate.
- What I’m watching: whether the 10-year Treasury yield can stay above 5% and whether Brent stays above $100.

Market Organized takeaway
The indexes are showing impressive resilience given 5%+ Treasury yields and $100+ oil, but that resilience increasingly depends on AI-related leadership. Next week’s inflation and employment numbers therefore matter enormously: softer readings could relieve some bond-market pressure, while stronger numbers could reinforce expectations for another Fed hike.
Confirmed: AI investment and demand remain strong. Still uncertain: whether that strength can keep overpowering increasingly restrictive financial conditions. These are scenarios to monitor, not forecasts to treat as settled.
Stay sharp, stay organized.
