US stocks fell sharply on Friday, October 30, 2026, as disappointing results from Amazon and Intel turned a nervous week for technology shares into a full US stock market selloff. The Nasdaq Composite tumbled 2.4%, the S&P 500 lost 0.3% and the Dow Jones Industrial Average fell 185 points, as investors questioned how quickly the enormous sums being poured into artificial intelligence will pay off.
The selloff was led by the very companies at the centre of the AI boom. Amazon dropped nearly 4.5% and Intel sank more than 28% after their quarterly updates, while chipmakers including Nvidia, Micron and Arm also fell hard. The losses extended Alphabet's bruising run after its 12.6% plunge on Thursday, and pushed the Nasdaq toward its first monthly decline in three months.
The warning signs were visible before Wall Street opened. Nasdaq 100 futures sank 2.33%, or 687 points, S&P 500 contracts lost 1.04% and Dow futures were little changed, up 0.03%, as traders digested results released after Thursday's close. Amazon had fallen 7.2% in pre-market trading and Intel was down about 25% before the bell, setting the tone for a session dominated by selling in technology.
Once trading began, the declines deepened. At 9:35 a.m. Eastern the Nasdaq Composite was down 2.5%, with Intel down 28.8%, according to Associated Press reporting. By 10 a.m. the Composite was down 2% and the S&P 500 down 1.1%. In Friday's reported session, the Nasdaq closed down 2.4%, the S&P 500 down 0.3% and the Dow down 185 points.
The selling was concentrated, not indiscriminate. More than 400 S&P 500 members had advanced on Thursday as investors rotated into defensive shares, and on Friday energy producers again stood out. ExxonMobil gained 2.1% after beating earnings expectations and Chevron advanced 1.4% as both earnings and revenue came in above forecasts. For the week, the S&P 500 was still up around 1% and the Nasdaq up 1.1%, while the Dow was down about 0.7%.
Friday's fall did not come out of nowhere. It was the second leg of a two-day reckoning for big technology. On Thursday, Alphabet posted a record one-day drop of about 12%, wiping more than $500 billion from its market value after its results missed expectations, and the Nasdaq Composite fell 1.38% to 26,184.72 while the S&P 500 slipped 0.3% to 7,720.39 and the Dow fell 132.54 points to 52,342.56. Microsoft finished marginally lower despite beating forecasts.
The broader backdrop made investors less forgiving. The Federal Reserve held interest rates at 3.75% to 4% on Wednesday, with two policymakers favouring an increase, and September's Personal Consumption Expenditures index climbed 3.6% from a year earlier, up from 3.4% in August, while core inflation reached 3.1%. On Friday morning, the third-quarter Employment Cost Index rose 0.8%, in line with forecasts, leaving wage growth still trailing inflation for many workers. Richmond Fed President Tom Barkin said the same day that the direction for rates was clear, with the pace the open question.
Asia had already signalled the mood overnight. South Korea's KOSPI closed down 3.48% after losing more than 5% intraday, with Samsung Electronics shedding about 3% and SK Hynix dropping about 7%. Japan's Nikkei fell about 2.1%. Brent crude rose toward $117 a barrel for the December contract, with the January contract nearer $113, after a tanker strike in the Strait of Hormuz renewed Gulf shipping concerns.
Amazon's numbers explain why a strong quarter could still sink a stock. Amazon Web Services sales rose 39.3% to $46 billion in the third quarter ended September 30, the segment's fastest growth in about five years, according to the Associated Press. Yet the company also spent $94.8 billion on property and equipment in the quarter, its trailing 12-month free cash flow swung to a negative $42.4 billion, and chief executive Andy Jassy said Amazon expects to spend $220 billion in capital expenditure during 2026, most of it on building AI data centres.
Intel's story was different in detail but similar in market logic. The company reported quarterly earnings above analysts' expectations, yet its shares collapsed because its fourth-quarter earnings estimate came in below forecasts and pressure continued in the personal-computer sector, with weak PC demand, manufacturing constraints and expected cash burn. Reuters reported Amazon and Intel risked losing about $300 billion in combined market value, potentially putting the Nasdaq-100 on course to shed about $1 trillion, after it had already lost about $1.4 trillion in October.
Reddit added a different kind of AI warning. Its shares plunged 21.1% in pre-market trading, and fell about 19.5% during the session, after chief executive Steve Huffman warned daily users could fall by a low double-digit percentage in the fourth quarter if search referrals keep declining. Search referrals fell by more than one million a week on average in October, Huffman said, blaming Google's AI search answers, overshadowing third-quarter revenue of $895 million, up 53%.
Market strategist Art Hogan framed Friday's move as repositioning rather than panic, telling Reuters: "I don't think this is a broader correction... It's a shift from a very popular technology trade into safer havens." That distinction matters for investors trying to judge whether the selloff is a healthy reset after a long AI-driven rally or the start of something deeper. A rotation into defensive stocks and energy shares, rather than indiscriminate selling across every sector, fits Hogan's reading.
The oil market told its own story. MST Marquee analyst Saul Kavonic said attacks in the Gulf and doubts over diplomacy were supporting crude prices, a combination that helps energy producers but threatens to keep inflation elevated and squeeze consumers. Higher fuel costs complicate the Federal Reserve's policy outlook at exactly the moment when officials are debating whether high inflation justifies another rate increase in December.
The central question is simple: when does AI spending start paying for itself? The combined spending of Amazon, Alphabet, Microsoft and Meta exceeded $200 billion in the third quarter alone, according to Swissquote Bank analyst Ipek Ozkardeskaya. With inflation at 3.6% and the Fed on hold at 3.75% to 4%, patience is thinner.
That matters beyond trading screens. Technology shares dominate US index funds and retirement accounts, so a 2.4% Nasdaq fall feeds quickly into household wealth, while higher oil prices hit consumers at the pump and through transport and food costs.
Traders will now watch three things. First, whether the next wave of corporate guidance steadies nerves or confirms that AI returns are further away than hoped. Second, November's inflation and jobs data, which will shape the Federal Reserve's December 8-9 meeting and the market's pricing of more than 50 basis points of rate increases by mid-2027. Third, oil and the Strait of Hormuz, where any further shipping disruption could push crude higher and complicate both inflation and the Fed's decision.
Despite the rout, the S&P 500 and Nasdaq remained on course for weekly gains, and October's scoreboard — Nasdaq down 2.5% for the month, S&P 500 up 0.9% and Dow up 2.8% — shows a market that has rotated rather than collapsed.
Why did US stocks fall on October 30, 2026?

Yes. ExxonMobil gained 2.1% and Chevron rose 1.4% after beating earnings expectations, as Brent crude climbed toward $117 a barrel amid Gulf shipping concerns.
What should investors watch next?
Further guidance, November inflation and jobs data ahead of the Fed's December meeting, and oil prices.
