Stock Market Today: Oil at $116 and AI Doubts Hit Global Shares

The stock market today is being pulled by two forces at once: surging oil prices tied to Middle East tensions and a loss of confidence in the financing behind artificial intelligence spending. On Friday, October 23, 2026, CNBC reported that the Dow Jones Industrial Average fell 652.82 points, or 1.23%, to close at 52,215.16. The S&P 500 slipped 0.52% to 7,623.68, and the Nasdaq Composite lost 0.21% to 25,955.34.

The moves matter beyond Wall Street because they combine energy, inflation and interest-rate risk, which together shape borrowing costs and growth for importing economies worldwide.

What is driving the stock market today?

The immediate trigger was a technology sell-off on Thursday, October 22. The S&P 500 dropped 1.2% and the Nasdaq Composite tumbled 2.6% that day, according to Yahoo Finance, as worries over the AI trade resurfaced after earnings from Tesla and Meta.

On Friday the selling spread. CNBC said defensive sectors such as consumer staples, utilities and healthcare also fell. American Express dropped more than 3% after announcing it would cut about 5% of its global workforce, citing the need to prepare for AI.

Funding strain in the AI sector is part of the story. CNBC reported that CoreWeave shares have sold off over the past week amid fears about its AI-related debt, with the cost of insuring that debt against default widening to levels generally seen as distressed. On the week, the S&P 500 lost 0.5% and the Nasdaq shed 0.7%, while the Dow gained 0.4%.

Why is oil at a five-month high?

Brent crude, the international oil benchmark, rose 3.1% to settle at $116.72 on Friday, its highest settlement since April. West Texas Intermediate futures gained 3.8% to settle at $103.27.

Reuters reported that Houthi attacks in Saudi Arabia stoked concern over further disruption to energy supplies from the Middle East. Reuters also noted that UAE authorities reported an oil spill off the Umm Al Quwain coast. UBS analyst Giovanni Staunovo said the market remains worried about escalation that could renew supply disruptions, per the same Reuters report.

The wider backdrop is the regional war that began in late February. CNBC linked Friday’s gains to reports that the US and Israel may be drawing up plans for renewed attacks on Iran. The Wall Street Journal, as relayed by Political Wire, said Iran warned it would strike civilian targets in neighboring countries if the US and Israel restart their air campaign. For background on those reported plans, see the Intelligence Report analysis of the reported US-Israeli plans to resume attacks on Iran.

Physical flows are recovering but remain fragile. Mansfield Energy said tanker convoys along the Omani coast under US naval protection have supported the recovery, while about one-third of crossings still use the northern route controlled by Iran. Analysts also point to a longer-running imbalance, covered in Citi’s Brent outlook and the question of why more Gulf oil has not cut prices.

What does it mean for the Fed and for Europe?

Higher energy costs complicate the Federal Reserve’s task. Markets and economists expect the central bank to leave rates unchanged at its October 28 meeting, according to an Investing.com preview. Traders put the probability of a December hike at roughly 80%, per Trading Economics, though other sources cited figures in the low to mid 70s, so the exact pricing varied through the session.

Bond markets sent a mixed signal. The 10-year Treasury yield fell below 5% to a one-month low on Thursday, according to Charles Schwab, as investors sought safety. Oil-driven inflation risk and weaker equities are pulling rate expectations in opposite directions, a tension also visible in the ten-week low in gold prices.

European shares were softer. Reuters reported that the pan-European STOXX 600 fell 0.31% to 635.77 on Friday and is down about 1.4% for the week, and described it as the steepest weekly loss since early September. Reuters cited higher crude and unrest in France as additional pressures. Kering dropped 16.6% after third-quarter sales at Gucci fell.

In Britain, retail sales fell 0.4% in September, a steeper drop than the 0.1% decline forecast, which puts consumer spending in focus ahead of the government’s budget on October 28, CNBC reported.

Is the AI sell-off over?

Not necessarily. One analysis published on October 23 noted that a single session of stabilization does not establish that the AI correction has ended. CNBC data also show a divergence: the S&P 500 excluding AI stocks was up 12.4% this year as of Thursday, edging out the broader index’s gain of roughly 12%.

Analysts quoted by AJ Bell and others tie the two themes together. Danni Hewson, head of financial analysis at AJ Bell, said global markets were contending with concerns about surging oil prices and the sustainability of AI spending, as reported by Malay Mail.

What to watch

• October 28: the Federal Reserve’s policy decision, where a hold is widely expected, and the language on energy-driven inflation.
• October 28: the UK government’s budget, which arrives as consumer spending weakens.
• Brent crude near $116: whether Houthi attacks on Saudi energy infrastructure continue, and whether Hormuz convoy traffic holds.
• US-Israel decisions on Iran: reports that strikes could resume after the US midterm elections, and any Iranian retaliation against neighboring states.
• AI financing signals: credit spreads for heavily indebted AI infrastructure firms and further earnings from large technology companies.

For the trading week beginning October 26, the central question is whether energy prices or AI valuations dominate. A Brent move through the session high of $117.45 reported by Reuters would intensify the inflation debate, while a calm Gulf could let equities refocus on earnings.
