Stocks fell hard on Friday, October 30, 2026. The S&P 500 dropped 140.32 points to 7,580.07, the Dow Jones Industrial Average lost 572.25 points to 51,770.31, and the Nasdaq Composite fell 747.73 points to 25,437.00, its worst day since June 5. The Russell 2000 slipped 47.37 points to 2,811.84.

Unlike some past selloffs, tariffs were not the story. No major new tariff headline emerged in Friday's market coverage. Instead, the session was driven by corporate earnings, energy prices, a crypto shock and the interest-rate outlook.

What actually moved markets

The biggest driver was technology earnings. Intel (NASDAQ:INTC) guided fourth-quarter revenue well short of expectations and warned of cash burn, citing a weak PC market tied to memory prices, Manufacturing hurdles and a factory accident in Israel. Its shares suffered what market reports called the steepest one-day drop on record, and the Philadelphia Semiconductor index slid to 10,688.80. Amazon (NASDAQ:AMZN)'s trailing 12-month free Cash Flow of negative $42.4 billion and Alphabet (NASDAQ:GOOGL)'s record Thursday selloff added to fears about AI spending.

Oil was a second force. December West Texas Intermediate rose $2.12 to $104.12 a barrel on tensions around Iran and the Strait of Hormuz, and January Brent settled at $113.43.

Crypto added a third. Binance reportedly lost about $6.3 billion in a hack that blockchain analytics firms TRM Labs and Elliptic tied to North Korea. Bitcoin fell to roughly $77,000, and crypto-linked stocks such as Coinbase (NASDAQ:COIN) and Strategy slid.

The Federal Reserve was the fourth. After holding rates steady this week, the Fed faces market pricing for a December hike, and three officials said on Friday that rates need to go higher.

Tariffs in the background

Tariffs still appeared in corporate results, but as a past cost being unwound rather than a new threat. ACCO Brands raised its 2026 forecast, citing tariff refunds and its Acquisition of computer-accessories maker Trust. Illumina (NASDAQ:ILMN) said its third-quarter revenue of $1.13 billion came after $37 million of tariff refunds passed on to customers; excluding them, revenue was $1.17 billion.

Those details suggest companies are now working through the effects of earlier trade measures rather than reacting to fresh ones.

A rotation, not a trade scare

Friday's market behaved more like a rotation than a broad flight from risk. Energy, consumer staples, utilities and health care rose, and six of 11 sectors finished higher. The equal-weight S&P 500 fell far less than the cap-weighted index, showing the damage was concentrated in megacaps and chips.

"The message from investors is becoming clearer: strong AI Demand is no longer enough on its own," said a senior market analyst. An Investment strategist said: "The market is much more broad than people generally want to give it Credit for."

What to watch

Trade could return to the agenda after the midterm elections on Tuesday, November 3, depending on the results. Democrats are widely predicted to win the House, while the Senate is more in doubt, according to market data.

For now, the calendar is dominated by other catalysts. Apple (NASDAQ:AAPL) and Palantir (NASDAQ:PLTR) report Monday, Qualcomm (NASDAQ:QCOM) reports November 4, ISM surveys are due during the week, and the October jobs report arrives Friday, November 6. Investors will also track the Iran war's effect on oil and any further fallout from the Binance hack.
