Silicon Valley moves fast and breaks things, but the U.S. electrical grid moves slowly and requires permits.

  • The explosive growth of AI is colliding with the glacial pace of building out new power infrastructure, prompting a new warning from Goldman Sachs that energy bottlenecks are set to stall the AI race.

Why it matters: Amid a wave of anxiety from Wall Street about the debt-fueled AI buildout, Goldman points to power as the biggest risk to trillions in spending in a new report shared exclusively with Axios.

Driving the news: Goldman expects global data center power demand to surge 170% between 2025 and 2030, with more than 60% of that growth coming from the U.S., according to the report.

  • "Power is probably the forever bottleneck," Jason Tofsky, Goldman's global head of digital infrastructure investment banking, noted in the report.
  • The bank estimates roughly $7.6 trillion in capital spending between 2026 and 2031 across computing, data centers and power infrastructure.

Zoom in: The physical infrastructure needed to support AI is moving far more slowly than the technology itself.

  • The U.S. has roughly 2,600 gigawatts of proposed power generation and storage projects awaiting grid connections, more than twice the grid's existing installed capacity, though many projects may never materialize.
  • The median time from an application for a grid connection to commercial operation is roughly five years.

Between the lines: The so-called AI race, which has long been defined by advances in frontier AI models, is really about who can get their hands on enough power, Goldman argues.

  • That could mean a longer, less predictable buildout, delayed financial returns and greater risks for companies investing heavily before securing power.

Follow the money: The massive expansion is being financed with debt, raising the stakes if construction timelines slip.

  • Goldman projects $420 billion in global hyperscaler debt issuance in 2027, up more than 60% from its 2026 estimate.
  • Debt is expected to finance roughly 35% of hyperscaler capital expenditures next year.
  • And hyperscalers account for just 40% of AI ecosystem credit fundraising, underscoring how widely the borrowing extends.

The intrigue: Since January, 86 projects have been canceled or significantly delayed, including 76 directly linked to local opposition, according to Goldman.

  • Put together, this paints a picture of extended delays.

Yes, but: Slower deployment could also help prevent over-investment by giving actual demand time to catch up with spending.

Meanwhile: The boom is transforming utilities from traditionally slow-growing businesses into major beneficiaries of AI investment.

  • Utility capital plans are expected to reach $1.3 trillion between 2026 and 2030.
  • Tech giants are considering arrangements to directly fund the power generation, transmission lines and electrical infrastructure their data centers require.

The bottom line: If you build AI systems, users will come, but they can only stay if there's enough power to go around.
