Nvidia stock was edging down early Wednesday. Its next generation of artificial-intelligence chips could face a delay, according to one analyst.

Nvidia shares were down 0.1% at $182.97 in premarket trading. The stock rose 0.6% on Tuesday.

The noise around the stock has been dominated in recent days by news around its business in China but that could be overshadowed by an analyst’s claim that Nvidia’s next-generation Rubin hardware is being pushed back to better rival Advanced Micro Devices .

“We think it is very likely that Rubin will be delayed. The first version of Rubin was already taped out in late June but Nvidia is now redesigning the chip to better match AMD’s upcoming MI450,” wrote Fubon Research analyst Sherman Shang in a research note.

Shang said that while the market is generally expecting mass production of Rubin chips to begin in the third quarter of 2026, supply-chain checks suggest only “limited volume” next year as Nvidia looks to increase the power of the processor, presenting challenges in manufacturing.

Nvidia didn’t immediately respond to a request for comment early on Wednesday.

Meanwhile, AI cloud company CoreWeave said Tuesday that demand is “insatiable” alongside its earnings report and it expects Nvidia’s latest GB200/GB300 NVL72 AI servers to do well over the next four quarters. CoreWeave rents out servers exclusively using Nvidia hardware, and Nvidia is an investor in the company.

“We have never wavered from our belief that the market is structurally supply-constrained, and that is based on our discussions and relationships with the largest, most important consumers of this infrastructure in the world,” CoreWeave CEO Michael Intrator told analysts on an earnings call.

Among other chip makers, AMD was up 1.2% and Broadcom was gaining 0.6% in premarket trading.
