• Amazon is on an unprecedented spending spree to build more AI data center capacity than anyone else.
• The company has extensive experience, yet even it's struggling to bring capacity online fast enough.
• Internal documents show Amazon getting bilions of dollars of Nvidia GPUs before they can be deployed.

At an internal staff meeting in September, AWS CFO John Felton had a joke for Prasad Kalyanaraman, the executive overseeing much of Amazon's AI infrastructure expansion.

"You've taken us free cash flow negative as a company, so congratulations," Felton said, according to a recording of the meeting obtained by Business Insider.

The remark was lighthearted. But it captured a stunning reversal.

Just two years ago, Wall Street was debating what Amazon would do with its growing cash hoard. Now, cash flow has evaporated as Amazon embarks on its biggest bet ever, spending $220 billion this year alone to build the physical backbone for AI.

At the meeting, Kalyanaraman did not dispute Felton's premise. Amazon's machine-learning and AI business is "hugely free cash flow negative," he said, adding that he expects the company's free cash flow to remain negative for "the next couple of years or so."

Amazon has made big bets before. It spent heavily on cloud computing, fulfillment centers, and its delivery network long before they became some of the company's most valuable assets. Investors questioned those investments at the time, but Amazon ultimately built enormous, profitable businesses from them.

AI is testing this playbook at a far larger scale. Amazon is committing hundreds of billions of dollars to data centers, servers, and power before investors know how quickly those investments will generate revenue.

The company is the best, or among the best, at building data centers, with decades of experience. But the size and complexity of these projects, and the bottlenecks holding progress back, are challenging — even for such a respected cloud pioneer.

Internal documents reviewed by Business Insider and people familiar with the matter show the company trying to coordinate a sprawling industrial system whose parts move on different schedules. A delay in power, equipment, or construction can leave billions of dollars in hardware waiting — and Amazon's cash tied up — while forecasts and costs keep shifting.

Why Amazon thinks it will work

Amazon says it has strong evidence that the capacity will be needed. AWS revenue grew 37% in the second quarter, its fastest pace in 18 quarters, while its backlog reached $496 billion.

CEO Andy Jassy thinks the company has a "clear line of sight" to strong financial returns from this record investment cycle. In his latest annual shareholder letter, he called AI a "once in a lifetime opportunity" and said Amazon would not be conservative in its investments.

"We've been through this cycle with the first big AWS growth wave, and liked the results," Jassy wrote. "We expect to feel similarly about this next wave."

Investors are concerned by the scale of the industry's expansion, especially as AI data centers are costing more to build and taking longer to complete.

The market is "repricing anything that funds multi-year builds against revenue that arrives later," Dan Ives, an analyst at Yorkville Ives, wrote in a recent report. Growing uncertainty around data center permitting and the political fight over electricity prices have given investors another reason to question how quickly these investments will pay off, he added.

Racks, but not enough power

One major industry challenge is securing enough power to run the equipment that goes inside data centers. This includes expensive racks of servers that contain GPUs and other chips that train and run AI models and services such as ChatGPT.

Internal emails from August show Amazon preparing a new "Early Rack Receipt" process for an expected wave of server racks carrying Nvidia's GB300 chips at US facilities before final deployment.

One Amazon email projected the company would take delivery of about $5 billion of Nvidia GB300 racks in August, followed by another roughly $3 billion each month "for the foreseeable future."

Some AWS data center sites had room for more racks but not enough available power to turn them on, people familiar with the effort said, leaving the equipment to be staged at intermediary warehouses until the facilities were ready. These people asked not to be identified discussing sensitive matters.

Timing and coordination

Usually, Amazon doesn't pay for racks until the gear is put into a data center, leaving suppliers to carry the cost of the equipment in transit, according to the internal documents obtained by Business Insider. This helps the company conserve cash.

However, the intensity of the AI data center building boom has made this type of coordination harder. Amazon has to compete more for scarce resources as it jockeys with rivals for access to Nvidia GPUs and other AI components.

Under the new "Early Rack Receipt" process, Amazon now takes ownership of these racks earlier in the supply chain, rather than waiting until the equipment reaches a data center.

The means spending cash sooner. And any delays getting the racks installed and plugged into a reliable power source potentially pushes back the moment when revenue starts flowing from these assets.

At least one AWS supply chain team did not have "a clear forecasted path" for getting racks into data centers, according to one of the emails reviewed by Business Insider.

An Amazon spokesperson said the company routinely stages finished hardware near deployment sites so it can be installed once power capacity is available, calling that approach "best business practice."

The spokesperson added that AWS has "long-established systems" to track infrastructure assets and disputed that the broader company lacks a forecasted path for getting racks into data centers.

This problem is not unique to Amazon.

Bernstein analysts wrote in a recent note that power permits, cooling systems, electrical equipment, construction, and hardware all move on separate schedules.

"Timing is imperfect," the analysts said.

"Inherently uncertain"

During the internal staff meeting in September, Felton, the AWS CFO, described the broader problem eloquently: "How do you work in the future when the future is inherently uncertain?"

Kalyanaraman, the AI infrastructure leader, said Amazon's internal outlook for the return on its AI investments had improved. But the assumptions behind those returns keep shifting.

"The forecast is changing on a daily basis," Kalyanaraman said. "The world that we live in is extremely dynamic."

Those shifting assumptions include when data centers will be ready and how much equipment AWS needs to keep on hand, he explained.

An eight-week supply buffer might be routine for a smaller company. But at Amazon's scale, Kalyanaraman said, this could mean holding "billions and billions of dollars" worth of additional equipment inventory — tying up precious cash.

Frugality meets the AI boom

Such tensions are especially striking for Kalyanaraman, a 21-year Amazon veteran who earlier this year was promoted to the elite S-team that reports directly to Jassy.

Amazon's founding story is defined by frugality. It famously used cheap doors as desks when founder Jeff Bezos started in Seattle in the mid-90s.

Kalyanaraman has absorbed this lore into bones. In late 2023, as AWS faced slower growth and layoffs, he urged employees to do more with less. "Frugality breeds innovation," he said back then.

That instinct still shapes his approach. In the September meeting this year, Kalyanaraman told Felton that AWS tries to make major investments at the "last responsible moment," when it has the clearest possible view of demand.

"If we can wait to spend the capital as late as possible, it's better for us," he said.

But the frenetic pace of the AI boom makes this principle difficult to follow. By the time demand is fully visible, the servers, power, and construction capabilities that AWS needs may no longer be available. That puts pressure on the company to commit more money sooner to secure supply and meet its data center capacity goals.

Kalyanaraman recalled telling Jassy in 2023 that AWS would "surely" be out of its capacity crunch by 2027. Instead, Amazon still expects demand to exceed its available capacity in 2027, the AI infrastructure chief said during the meeting this September.

Secured Power at Risk

Getting enough electricity may be the biggest challenge for an industry leader like Amazon.

The company has 44 gigawatts of data center capacity under development across 16 states, more than double Google, Meta, and Microsoft, according to Cleanview Research estimates.

An internal AWS dashboard called "Secured Power at Risk" tracks utility and regulatory constraints affecting electricity capacity AWS has lined up for its data centers.

The risks include transmission bottlenecks, requirements to reduce use during grid stress, and "use it or lose it" provisions that can jeopardize capacity if a data center project misses usage or construction milestones.

In other words, AWS is not simply waiting for electricity to arrive. It is managing a portfolio of commitments that can become more costly if a data center project is delayed.

Maryland proposals

A submission to Maryland's utility regulator last year, obtained through a public records request, illustrates the kind of exposure that can accompany massive data center buildouts.

Amazon told the Maryland Public Service Commission that large data center customers could help pay for grid upgrades or bring new power capacity to market without burdening other electricity ratepayers.

The company also proposed setting aside collateral to help utilities get more comfortable with the large investments needed to generate more electricity for data centers. Amazon proposed three years of collateral so that if a large electricity customer abandoned unused capacity, the utility would have time to re-sell the power.

The proposal is not evidence that AWS has made such a payment or posted collateral. It does, however, show that large data centers can face extra financial obligations, beyond their own electricity bills, if projects are delayed or cancelled.

The Amazon spokesperson said such utility rules are not unique to AWS. The company has not disclosed how much cash it has paid upfront to secure power.

New constraints 'keep popping up'

The AI buildout also incurs expenses that are harder to model than a conventional capex plan.

In the September meeting this year, Kalyanaraman said that while reviewing plans for gigawatts of capacity in West Texas, AWS confronted a labor problem: There weren't enough nearby pipefitters, electricians, and other skilled workers to build the facilities.

The company's response, he said, was to pay to construct housing complexes near its data centers so workers could live there for the two or three years needed to complete the projects.

Even the crates used to ship servers have become a planning issue. It may seem absurd to worry about the price of a container when servers cost hundreds of thousands of dollars, Kalyanaraman said. But at AWS's scale, where the company needs so many crates, even trivial items can become a material expense.

"We have new constraints that keep popping up," Kalyanaraman said.

• Meta is building its largest-ever data center in northeast Louisiana.
• A local community college is training data center technicians to work there.
• Data center jobs are in high demand and can pay handsomely.

Thousands of construction workers are arriving in a small Louisiana community to build Meta's largest-ever data center.

Less than an hour away, at the Louisiana Delta Community College's West Monroe campus, the next generation of data center professionals is hoping to join their ranks.

"I see AI is really the future. We're going to need data centers to house all the data," Eric Crowe Jr., 27, told Business Insider. "I feel like it will become a very lucrative job to have, and we're going to need more of them. Why not get in now before it gets oversaturated?"

Crowe Jr. is among the students who signed up for the community college's Data Center Technician program. The four-week, nearly $3,700 training course prepares students to enter the data center industry, which is rapidly expanding to support the age of AI.

Construction for Meta's nearly 10-million-square-foot data center, Hyperion, is underway in rural Richland Parish, where business is now thriving as workers flood the region.

Meta says the project will include over 7,500 trade workers on-site at peak construction and support 1,000 operational jobs once completed. For residents living in the region, where there's no state minimum wage law and agriculture is a major industry, the new opportunity to make good money in a growing sector is too enticing to ignore.

"This is a stepping stone into the real world," Dan McCarty, director of Workforce Trades at Louisiana Delta Community College, said. "We prepare you with a résumé. We work on every aspect of employability, safety, and technical skills."

The inaugural class graduated in March, and all 11 students received job offers from IES Communications, which employs people working on Meta's project. McCarty said the program, which is available at the Winnsboro campus, now produces about 24 graduates a month.

In the past, a lot of people, including myself, had to leave here to find the good jobs," McCarty said. "Now they're 30 minutes down the road."

'It's a no-brainer'

The Data Center Technician program teaches students everything from operating equipment to workplace safety. They'll also have the opportunity to earn several certificates. During a class this September, nine students huddled around Fletch Batchelor, an instructor specializing in broadband, as he explained how to splice fiber optic cables.

"Do you know why squirrels chew through cable? They like a high fiber diet," Batchelor said, earning some chuckles.

The program encourages students to take a hands-on approach, which Trey Wadley, 30, said he appreciates. During the class, he participated in a live cable splicing demonstration. Wadley, who's interested in cybersecurity and has a background in the automotive industry, learned about the program while scrolling on Facebook, which, incidentally, is owned by Meta.

"As I learned more about Meta and data centers, they piqued my interest," he said. "I said, 'Okay, this might be something that fits me and that I'm into. I decided to give it a try."

Wadley, who recently welcomed a baby girl, wants to find work with Meta's project so he can work locally. Without Meta's project, Wadley said he'd likely have gone looking for job opportunities in Texas.

The push from tech companies and the US government to build out the nation's AI infrastructure has made data center jobs a valuable new path to lucrative employment. Business Insider reported in August that the median pay for data-center facility managers was $134,000, which is 64% higher than that of other facilities managers. The median pay for project managers at data center facilities was $115,000, a 12% increase over similar roles at other facilities.

Wadley said he's hoping to secure a position paying between $25 and $30 an hour. So is Crowe Jr., who previously handled packages and drove for FedEx, where he was averaging $14 an hour.

"Here, I could make about $25 to $30 per hour. It's a no-brainer for lots of people to pivot," Crowe Jr., who has an interest in cybersecurity, said.

McCarty said entry-level positions could earn as much as $24 an hour, but students who've graduated told him they reached $27 to $28 an hour within six months.

Booked and busy

Residents in Richland Parish, like other communities in the United States, have mixed feelings about the data center. While some say it will bring new jobs and boost the local economy, others are concerned about environmental impacts and disruptions to their daily lives.

It's a reality not lost on Crowe Jr. and Wadley, but they said it's unlikely that AI will simply go away.

"I think we should focus more on solutions to how we can coexist with it," Wadley said.

Students attending the technician class in September also spent time in a mock data center on campus, where they could apply skills they'd learned in class in a real-world setting.

While they tinkered with the equipment, John Bradley, a broadband workforce development instructor, said having access to a similar program as a teen would have been invaluable.

"I chose an alternative route, which was in construction and oil fields, but if I'd have had something like this that would've guaranteed me a good job, good money from the get go, and I could travel if I wanted to, I would've loved that," he said.

Bradley said the program prepares its graduates to be hired by contractors specifically working with Meta.

"We have a special email that we give to different contractors we spoke with that are waiting for them to graduate our class," Bradley said.

However, working at Meta isn't a requirement of participating in the program. Bradley said the skills students learn during the course are transferable, especially as data centers and similar construction jobs become more popular.

"It doesn't have to be a Meta data center. You may decide, 'Hey, I don't want to work in data centers anymore.' You still got banks, you still got IT departments," Bradley said. "You can literally go to work anywhere you want and use the same trades you learned here."

McCarty said the program has a backlog of students trying to get into the course, so they're hoping to expand their offerings.

"We've got some that are fresh outta high school, but we've had students up to 60 years old," he said. "It doesn't really matter what age you decide to get into this trade. Anyone is welcome to come in and learn it."
