Americans are rallying against data centers. Surprisingly few are actually getting built

(CNN) — People really don’t like AI data centers.

Politicians are running against them. A recent Gallup poll showed 71% of Americans oppose them. Several counties and states have proposed or passed laws to ban them.

But this notion that AI data centers are quickly popping up everywhere is belied by the fact that their construction faces massive hurdles – regardless of whether anyone wants them in their backyard or not.

Delays

Construction delays are nothing new: Historically, around 72% of scheduled data center capacity comes online on time, according to Goldman Sachs.

But only about half of the AI computing capacity scheduled to activate between now and 2028 via data center construction is actually expected to come online by its target date, Goldman Sachs said. Data centers typically take 18 to 24 months to build, but completion times are getting stretched as delays are getting worse.

Despite $750 billion in AI infrastructure investments this year alone, according to JPMorgan, data centers are struggling to get shovels in the ground. About 60% of data center capacity planned for completion in 2027 hasn’t even begun construction, according to JPMorgan. Another 7% of projects that have gotten underway have since been delayed.

The planned American data center boom is absolutely massive.

The United States had 5,427 data centers at the end of last year, according to Stanford University’s AI Index Report. That number is set to nearly double: AI companies have announced plans for 3,969 new US data centers, according to Aterio, a data center research company.

Of those, just 802 are currently under construction.

There’s reason to believe many of those nearly 4,000 planned data centers were never real to begin with: Developers typically submit many simultaneous applications across multiple regions only to pick the most viable one, noted Goldman Sachs.

That’s why, of the 565 gigawatts of computing power AI companies are currently planning (more than 10 times today’s power), Columbia Business School real estate professor Stijn Van Nieuwerburgh expects just 180 gigawatts to actually get built over the next decade. Two-thirds of the pipeline is “implausible,” he says.

That still amounts to about $10 trillion of investment – 50% bigger than the next-biggest spending boom from the 19th century railroad expansion.

But sand is accumulating in the AI gears. That overwhelming demand for data center buildouts has vastly outstripped the industry’s ability to supply it.

What’s behind the delays?

Materials shortages: Building materials have become difficult to source because of surging demand.

Even if construction materials were readily available, the chips that the massive buildings house are in short supply. That’s particularly true for Taiwan’s TSMC, which fabricates virtually every leading AI chip, including Nvidia’s Blackwell and AMD’s MI300X. That makes TSMC “a single point of dependency in the global AI supply chain,” according to Stanford University’s AI Index report.

Power shortages: AI’s massive strains on the electrical grid have caused a significant supply and demand imbalance. Data centers already account for roughly 8% of US electricity usage, and that could grow to 12% by 2028, the American Edge Project, an AI data center advocacy group, predicts.

To compensate, many AI companies are building their own electricity-generation plants. But that plan has hit snags, too: Wait times for generation step-up transformers has tripled, according to JPMorgan. GE Vernova, the largest natural gas turbine manufacturer, reported that bookings for its power generators have doubled to $200 billion over a five-year period.

Since 2020, inflation for transformers and power regulators has surged the second most of all 47 categories that the Bureau of Labor Statistics measures in its monthly Producer Price Index, a gauge of wholesale inflation.

Labor shortages: To meet deadlines for the proposed data center buildouts, the United States would need to add 500,000 electricians, 300,000 welders and 550,000 plumbers, according to the American Edge Project. Recent changes in immigration policy haven’t helped.

“Some of our clients are developing 24/7/365, and contractors are moving around all day, but there’s nothing they can do if all the labor is tied up in existing projects,” said Joe Macejak, head of Marsh Risk’s US property digital infrastructure business.

Public opposition: About a dozen states have proposed data center building moratoriums, including two states – New York and Texas – that recently put those temporary bans into action. Four additional states have taken up similar bills, but they failed to get enacted.

Bans aren’t the biggest hurdle, though: Getting construction permits approved is, noted Goldman Sachs.

What’s actually getting built

Despite the delays, spending on data center construction still jumped 7% in June to $68.3 billion, according to a Census Bureau report. That was up an astounding 46% from a year earlier.

A single state-of-the-art AI campus can cost around $8 billion, according to Van Nieuwerburgh. Despite that steep cost and the delays, Van Nieuwerburgh expects

There are now 438 unique data center developers with projects in the US, according to Cleanview, an energy data company.

The spending is so massive that data centers are helping fuel inflation, noted Minneapolis Federal Reserve President Neel Kashkari last week.

Still, data centers can’t just pop up out of nowhere. They take years to plan and construct. And the web of contractors, local inspectors, developers, laborers, chipmakers and site managers adds cost, complexity, risk – and delays.

“It’s very hard to get the timing right with these big buildouts, and often what ends up happening is we get overexcited and accrue too much debt and then a bunch of these investments go bust,” said Van Nieuwerburgh.

Sherrill enters national political fray with first midterm endorsements

▶ Watch Video: Mikie Sherrill sworn in as New Jersey governor Washington — With three months to go until the critical midterm elections, New Jersey Gov. Mikie Sherrill is taking her first major step onto the national political stage to help Democratic candidates with military service win in competitive frontline races. The centrist Democrat, who won in a top battleground race last year, will use her federal political action committee to endorse a slate of Democratic contenders who are running in some of the country's most competitive congressional races as she signals an interest in shaping the Democratic Party's direction ahead of the 2028 presidential election, CBS News has learned.Sherrill's Mission to Deliver PAC will announce its first round of key endorsements Thursday, backing 13 Democratic candidates with military or national security backgrounds in House and Senate races across the midterm landscape.The candidates include Massachusetts Rep. Seth Moulton, who is mounting an insurgent challenge against two-term incumbent Democrat Sen. Edward Markey. The group is also endorsing Reps. Don Davis of North Carolina and Maggie Goodlander of New Hampshire, who represent what could be competitive districts — and, in Davis' case, a district that was redrawn to become more favorable to Republicans. Most of the other endorsees are aiming to unseat House Republicans in seats that Democrats are targeting, including former Rep. Elaine Luria of Virginia, JoAnna Mendoza of Arizona, Eileen Laubacher and Jessica Killin of Colorado, Bale Dalton of Florida, Zach Dembo of Kentucky, Rebecca Bennett of New Jersey and Cait Conley of New York. Also on the list: Maura Sullivan, who is running for the New Hampshire House seat currently held by Senate candidate Chris Pappas.The endorsements are the first from her PAC, which Sherrill launched to support candidates with military service and public leadership experience. According to a source familiar with Sherrill's plans, additional endorsements are expected in the coming months, and Sherrill plans to campaign aggressively for Democrats in key battleground states, including Nevada, New Hampshire, Texas and Wisconsin.Mission to Deliver PAC raked in just under $1.2 million in contributions between late last year and June 30, much of it from PACs linked to labor unions, according to Federal Election Commission filings.The effort comes as Sherrill, a former Navy helicopter pilot and Naval Academy graduate who was elected New Jersey governor last year after serving in Congress, seeks to build a national political profile at a pivotal moment for Democrats. As the party debates its identity following losses to President Trump and Republicans in the 2024 elections and looks ahead to an open presidential contest in 2028, Sherrill has increasingly emerged as part of a group of Democratic governors seeking to shape the party's future.In announcing the endorsements, Sherrill focused on the candidates' military service and contrasted them with Mr. Trump, who did not serve in the military."Each one of these candidates has taken multiple oaths to the U.S. Constitution. They know what it means to serve others and accomplish the mission, whatever it takes," Sherrill said in a statement to CBS News. "When we send veterans to Washington, we are sending in dedicated public servants who are trained to run towards the fight and are unafraid to take on the status quo."She also criticized Mr. Trump for launching a military campaign against Iran. Sherrill accused him of sending U.S. troops "into harm's way for a war he shouldn't have gotten into and can't get out of," while arguing he has prioritized personal interests over those of the country.The endorsements also emphasize Democrats' continued effort to recruit veterans for competitive congressional races, a strategy party leaders have embraced for years in swing districts where military credentials are viewed as an asset with independent and moderate voters.Sherrill's time in the Navy has long been a core part of her pitch to voters. After she was elected to the House in 2018, she was part of an informal caucus of newly elected House Democrats with intelligence or military backgrounds and fairly moderate politics who ousted GOP incumbents that year. Her fellow "national security Democrats" in 2018 included Rep. Jason Crow of Colorado, Luria, Abigail Spanberger, who is now Virginia's governor, and Elissa Slotkin, who now represents Michigan in the Senate.For Sherrill, the endorsements could represent more than a midterm strategy. It may help her establish the infrastructure of a national political operation that could give her influence over the next generation of Democratic leaders — and potentially the party's presidential field — well before the first votes are cast in the 2028 nominating contest.In a July interview with Politico Playbook marking six months in office, Sherrill acknowledged she hopes to play an influential role in selecting the Democratic Party's next presidential nominee."The short answer is yes," Sherrill said last month when asked whether she wants to be a 2028 power broker. "I want to make sure that what we see in any candidate in '28 and anybody that gets across the finish line, I want to see somebody who is on track with the focus that New Jersey has on creating opportunity for everyone and a great future for our kids."
