Wall Street ends its worst day since April 2025: Dow down 1,833 points, VIX at 28, chips crushed

Wall Street had its worst session in more than a year on Thursday. The Nasdaq Composite fell 5.52% to 24,315.00 and closed in correction territory, more than 10% below its Oct. 6 record close, according to CNBC. The S&P 500 lost 4.36% to 7,353.73 and the Dow shed 1,833.06 points, or 3.44%, to 51,523.06. CNBC said all three averages had their worst day since April 2025. This follows our afternoon update, which carried intraday readings; these are the final numbers.

The closing scoreboard

Source: Yahoo Finance closing data; CNBC and Fox Business for the index moves. Percent changes and distance from highs are our arithmetic on closing prices. The Nasdaq met the usual definition of a correction (a close at least 10% below the record), as Fox Business noted. CNBC said the Russell 2000 also entered a correction.

The number behind the number: a two-day round trip

Wednesday's rally and Thursday's rout together tell a different story than Thursday alone. From Tuesday's close to Thursday's, the S&P 500 is down 2.8%, the Nasdaq down 4.2% and the Dow down 0.5%. The Dow, which holds few chip names, is nearly flat on the two days, while the chip index is down about 15% over the same stretch (10,600 to 9,011). That is the pattern of one corner of the market doing the damage, and it explains why the Dow's drop looks smaller than the S&P's. CNBC's market team said the Dow's best day since April 2025 on Wednesday was more than wiped out.

What drove it

The explanation from CNBC and Fox Business is the same: investors worry that Democratic wins in Congress and governor's races will slow the buildout of AI data centers. CNBC cited Sen. Bernie Sanders' call for a national data center moratorium. Fox Business quoted eToro analyst Jakub Rochlitz saying the market read the results as making the AI buildout "slower and more expensive." Argent Capital's Jed Ellerbroek told Reuters it "feels like the capitulation phase" for data center beneficiaries, though he thought the size of the moves was "outsized."

It is worth keeping that in proportion. This is the market's reading of politics, and no moratorium has been enacted. We have found no company filing or official action changing any data center plan.

The reach was wide. CNBC reported Broadcom down about 10%, Nvidia about 9% and Oracle almost 7%, while Qualcomm fell 9% after an earnings outlook that disappointed even though it beat estimates. Fox Business put Tesla down about 10.8%. Neocloud names fell hard: CoreWeave almost 10%, Nebius about 15% and Iren almost 17%, per CNBC. Heading into the final hour, CNBC calculated the Magnificent Seven were losing roughly $900 billion of market value in aggregate. Selling then spread beyond tech: Caterpillar fell 6% and JPMorgan 4%.

Rates, oil, gold and the dollar

Safe-haven buying showed up modestly. Yahoo Finance's 10-year Treasury yield reading slipped to 4.84% from 4.89% on Wednesday. Gold futures closed near $4,098 an ounce, up about 0.6%. Front-month WTI crude settled near $90.85 a barrel, up about 3.1% after Wednesday's big drop. The dollar index finished little changed near 101.6.

Who it actually hits

Traders in leveraged chip ETFs and short-dated options had the worst of it. For owners, the exposure is less obvious. Electrical and HVAC contractors are the trades that wire and cool data centers, and our listings show about 25,380 independent electrical contractors and 40,729 independent HVAC businesses on file in the United States. Those that had a data center project in their backlog should not assume it is cancelled, because nothing says so, but a customer asking to "pause and review" is now plausible. Owners with variable-rate lines are in a different spot: the falling 10-year yield helps, as we laid out in this piece on credit lines.

What to watch Friday

The government jobs report is due Friday; our piece on ADP's October numbers covers what is expected. Volatility at 28 means the next move in either direction can be large.
