Intel’s stock took a hit early Wednesday following reports that Nvidia hit the brakes on a crucial manufacturing test. Sources say the AI chip giant decided to halt progress on Intel’s “18A” production process. The market reacted immediately, pushing Intel shares down about 2.3% before the opening bell in New York.
This development strikes a nerve because Intel has staked its future on the 18A technology. The company recently opened a massive new factory in Arizona, known as Fab 52, specifically to bring this technique to mass production. Intel markets 18A as the most advanced chip-making method on American soil. It is the centerpiece of their strategy to overtake Taiwan Semiconductor Manufacturing Co. (TSMC) and bring chip leadership back to the U.S.
The relationship between Intel and Nvidia is already complex. In September, Nvidia invested $5 billion in Intel, a move that followed the U.S. government’s acquisition of a 10% stake. At the time, investors saw Nvidia’s cash as a lifeline for Intel, which had struggled to turn a profit. However, that deal did not include a promise that Nvidia would actually use Intel’s factories. The halted test suggests that while Nvidia is willing to invest cash, it isn’t ready to trust Intel with its hardware production just yet.
At a technical level, the 18A process attempts to reinvent the transistor. Modern chips hold billions of these tiny switches. To make them faster and more efficient, engineers need better ways to turn them on and off. Intel’s new “gate-all-around” technology wraps the control gate around the entire channel, preventing energy leakage. This allows engineers to pack more transistors into a smaller space without overheating the device.
Intel claims this tech solves two massive problems: data handling and power consumption. But for the technology to matter, customers need to buy it. Nvidia designs the chips that power the global AI boom. If the world’s most valuable chip designer doesn’t feel confident in Intel’s manufacturing test, it casts doubt on whether Intel can truly compete at the highest level. For now, the industry waits to see if this is a permanent stop or just a bump in the road.
