Here's an awkward breakup for you: China has stopped taking Nvidia Corp.'s (NVDA) calls. After years of being the semiconductor giant's fastest-growing market for AI chips, Beijing essentially ghosted the company. And CEO Jensen Huang isn't pretending otherwise.

"We went from 95% market share to 0% … we are 100% out of China," Huang admitted recently, adding that "in all our forecasts, we assume zero for China."

For a market that once represented a significant chunk of Nvidia's data center revenue, this isn't a cooling-off period. It's a complete shutdown.

How Beijing Slammed the Door

The signals from China have grown increasingly direct. In November, regulators reportedly banned foreign AI chips—including Nvidia's—from new state-funded data center projects. Projects less than 30% complete were ordered to rip out imported hardware entirely and replace it with domestic alternatives.

A month earlier, customs officials ramped up scrutiny on semiconductor imports at major ports, making it significantly harder to move Nvidia GPUs into the country at scale. Meanwhile, China's industrial policy kicked into overdrive, with plans to triple domestic AI chip production by 2026 and new alliances aimed at building a self-sufficient tech stack from silicon to software.

Then there's the oversupply problem. Analysts say Chinese tech companies panic-bought Nvidia chips through both official channels and gray markets during the initial export restriction chaos. Now, combined with rapidly improving homegrown alternatives, China has stockpiled enough AI hardware to last for years. When your shelves are full and nationalism is good for business, demand for fresh Nvidia shipments evaporates quickly.

Huang's Response: The World Is Bigger Than China

But Huang isn't dwelling on the loss. He's reframing the entire story, arguing that Nvidia doesn't actually need China to ride the AI wave. He recently projected that global AI infrastructure spending could reach $3 trillion to $4 trillion by the end of the decade—a market opportunity that dwarfs what China could have provided even under the best circumstances.

It's a bold strategic pivot: if China ghosts you, bet on the rest of the world picking up the phone.

The real question for investors isn't whether Nvidia can survive losing China—it clearly can. The question is whether that projected multi-trillion-dollar AI buildout in other markets will materialize fast enough to offset the sudden revenue gap. For now, the breakup is official. The comeback story? Still being written.
