A fall with no earnings behind it
The Nasdaq Composite closed at 24,315.00 on 5 November, down from 25,736.51 the day before — a fall of 1,421.51 points, or 5.52%, according to the exchange’s own historical data. The index opened at 25,558.11, touched a high of 25,559.03 in the first minutes and bottomed at 24,262.14. CNBC reported the S&P 500 down 4.36% to 7,353.73 and the Dow down 1,833.06 points, or 3.44%, to 51,523.06. NPR put the market value erased at more than $2tn.
No frontier lab reported a bad quarter. No model failed. What changed was the composition of the next Congress and of several statehouses, and with it the probability that the data centre buildout will be slowed by people who can slow it.
The sell-off followed the supply chain
The damage tracked proximity to AI infrastructure rather than to AI products. CNBC listed Broadcom down 10%, Nvidia down 9%, Oracle down almost 7%, CoreWeave down almost 10%, Nebius down about 15%, Iren down almost 17%, Astera Labs down about 17% and MACOM down about 18%. AMD and Micron each fell 15% and Arm about 12%. Qualcomm fell 9% despite beating earnings estimates, on a weaker outlook.
Outside technology the losses were smaller and still broad: Caterpillar down 6%, JPMorgan down 4%, Boeing and Nike down 2% each. The Motley Fool’s sector data put technology down 5.54% and industrials down 5.18%, with gold up 0.46% to $4,091.80 and the ten-year Treasury yield down five basis points to 4.90%.
What the market thinks it learned
The reading investors took is political. On the same ballots, voters went against data centres in 40 of 41 local measures, and governors who campaigned on pausing or policing the buildout won in Texas, Ohio and Georgia. Senator Bernie Sanders, who caucuses with the Democrats and has called for a national data centre moratorium, wrote on X that “Americans don’t want Big Tech oligarchs wrecking the environment, gutting jobs and threatening humanity’s future.”
Tim Holland, chief investment officer at Orion, told CNBC that “it’s about tone and tenor from the party that did really well”. Keith Lerner, chief investment officer at Truist Wealth, said “the rubber band is becoming increasingly stretched”. The Macro Research Board wrote in a Thursday note that “the shakeout in A.I.-related stocks has much further to run”.
The gap between a vote and a rule
None of this is yet a rule. The local measures bind individual municipalities, a new Congress is not seated until January, and the one federal step reported this week is an inventory of laws that already apply to AI labs rather than any new ones. What repriced on Thursday was not a change in what the industry is allowed to do but a change in who will decide.
That gap is the thing to watch. The buildout’s financing assumes capacity arriving on schedule, and the schedule now runs through county commissions and state legislatures that have just been handed a mandate. The next hard datapoint is Clarksville, Arkansas on 1 December, where voters decide whether to uphold bond ordinances supporting a project — the first local test since the sweep.
