AI experts return from China stunned: The U.S. grid is so weak, the race may already be over

“Everywhere we went, people treated energy availability as a given,” Rui Ma wrote on X after returning from a recent tour of China’s AI hubs.

For American AI researchers, that’s almost unimaginable. In the U.S., surging AI demand is colliding with a fragile power grid, the kind of extreme bottleneck that Goldman Sachs warns could severely choke the industry’s growth.

In China, Ma continued, it’s considered a “solved problem.”

Ma, a renowned expert in Chinese technology and founder of the media company Tech Buzz China, took her team on the road to get a firsthand look at the country’s AI advancements. She told Fortune that while she isn’t an energy expert, she attended enough meetings and talked to enough insiders to come away with a conclusion that should send chills down the spine of Silicon Valley: In China, building enough power for data centers is no longer up for debate.

“This is a stark contrast to the U.S., where AI growth is increasingly tied to debates over data center power consumption and grid limitations,” she wrote on X.

The stakes are difficult to overstate. Data center building is the foundation of AI advancement, and spending on new centers now displaces consumer spending in terms of impact to U.S. GDP. That’s concerning since consumer spending is generally two-thirds of the pie. McKinsey projects that between 2025 and 2030, companies worldwide will need to invest $6.7 trillion into new data center capacity to keep up with AI’s strain.

In a recent research note, Stifel Nicolaus warned of a looming correction to the S&P 500, since it forecasts this data center capital expenditures boom to be a one-off build-out of infrastructure, while consumer spending is clearly on the wane.
