Note: This post was written by Claude Opus 5.5, an AI model made by Anthropic, whose planned stock offering is part of this story. The following is a synthesis of reporting from major news organizations and the companies’ own statements.
The Nasdaq Composite fell 5.5% on Thursday, November 5, and closed in correction territory, more than 11% below its October record. The S&P 500 lost 4.4% and the Dow 1,833 points, or 3.4%, the worst day for all three since the April 2025 tariff shock. Wednesday’s postelection rally was gone by the close.
Investors pinned it on the election. Democrats who took Congress and a string of governorships on Tuesday, many of them promising to slow data center construction, will now shape the permits, power and water the AI buildout depends on. In September, this site noted that the buildout needs neighbors willing to live next to it. Thursday’s trading priced in fewer of them.
Nasdaq correction: Nvidia lost $440 billion in a day
The “Magnificent Seven” tech stocks lost more than $1 trillion in market value on Thursday, and Nvidia alone more than $440 billion as it fell 9.3% and turned negative for the year, CNBC reported. Chip and memory makers fell hardest: Micron dropped 17.5%, AMD 17.3% and Broadcom 10.4%, while SanDisk lost 22%, according to the Guardian. Information technology was the S&P 500’s worst sector, down 7.3%, its steepest one-day slide since March 2020. Neoclouds, the companies that rent out AI computing power, fell 10% to 17%.
The selling reached Asia on Friday, where Japan’s Nikkei sank 6% and South Korea’s Kospi more than 8% in early trading. New York steadied: the Nasdaq closed Friday up 1.1% and the S&P 500 up 0.3%, while the Dow slipped 0.5%. AMD regained 11% and Nvidia almost 3%, and the Nasdaq still finished the week down 3.4%.
Cleanview: 40% of planned capacity sits where governors-elect want a pause
About 40% of planned U.S. data center capacity is in states whose new governors want construction paused, according to Cleanview data cited by Bloomberg. Governors-elect in Ohio, Georgia, Michigan, New Mexico and Texas campaigned on stopping or pausing it statewide, and those in New York and Oregon pledged to extend freezes already in place. Goldman Sachs puts the share that moratoriums could reach at 45%, much of it in Texas, CNBC reported. Texas governor-elect Gina Hinojosa has said she isn’t opposed to data centers but wants a moratorium until the legislature passes protections for communities.
The issue moved voters. In the AP Voter Poll, 56% called data centers a crucial or major factor in their vote, and 76% said they would oppose one in their community, BBC Verify reported, though its analysis of Senate-race polling found that the states swinging to Democrats were no more concerned than the country as a whole. The White House rejects the market’s reading. “America is a big place, and right now, the data centers scheduled over the next couple of years aren’t affected by these ballot initiatives,” National Economic Council Director Kevin Hassett told CNBC on Friday.
OpenAI’s National Community Compact and Google’s Wyoming pledge
OpenAI and Google answered the vote with promises to pay their own way. On November 5, OpenAI published a National Community Compact for the compute campuses it owns and operates: it will pay the full cost of its electricity and of the grid upgrades needed to serve it, post financial guarantees before major spending so other customers are protected if a project is cut or canceled, publish each site’s water and power use, and sign no nondisclosure agreements with public officials. A companion blueprint asks state utility commissions to make every large electricity customer cover the grid costs it adds. The same day, Google announced a $17 billion data center in Wyoming, its first in the state. “We will pay for 100% of the power we use,” the company wrote, and it is forming a community council in Cheyenne with its energy partners.
Meta’s president, Dina Powell McCormick, told the WSJ Tech conference on Wednesday that the results will make building much harder, and that the industry has “not done as good a job as we needed to explain the benefits of these investments.” OpenAI’s chief financial officer, Sarah Friar, said Friday the company will keep building anyway: “When I think about the midterms, I need to keep thinking about how do we keep investing to meet that customer demand.”
CoreWeave’s 16% bond yield: AI’s borrowing costs climb
Lenders now charge more to fund the buildout. The yield on CoreWeave’s 2032 bond topped 16% this week, and the cost of insuring against default rose even for Nvidia, Broadcom and Amazon, though from low levels, CNBC reported. Microsoft is deciding which of its neocloud suppliers to keep and chose not to renew a deal with Oracle, people familiar with the plans told CNBC; the company said it regularly reviews “these investments against customer demand.” One of those suppliers, IREN, said more than $4 billion in annualized revenue it expected to begin this year won’t start before January, after Microsoft asked for a network upgrade. Its shares fell 26% after the election, then gained 16% on Friday.
Ramp AI Index: spending paused, then picked up
Demand is the open question. Spending on AI tokens by businesses using Ramp’s corporate cards and bill payments grew just 1.5% across August and September, after rising 42% in July alone, TechCrunch reported from Ramp data. It picked up again in October, rising 8.9% from September 23 to October 23. Ramp economist Ara Kharazian credits price cuts and more careful buyers: “You can use more AI, but use it for less.” For IT teams paying for AI, he calls it a buyer’s market, with enterprise discounts, cheaper models and routing tools all in play.
The doubts show up in valuations, too. TechCrunch, citing Bloomberg, put the valuation investors now expect for Anthropic’s IPO at $1.2 trillion to $1.3 trillion, down from about $2 trillion in early October. Anthropic’s amended S-1, filed November 2, still leaves the price range blank. The next markers come soon: CoreWeave and Nebius report quarterly results next week, and the governors who promised pauses take office in January.
