Nvidia kept rising in premarket trading after jumping over 8% on Wednesday.

Nvidia stock gained ground in conjunction with a report from Semafor that the U.S. was considering lifting restrictions on the sale of advanced semiconductors to Saudi Arabia. If so, it would open up a new market for the AI company.

Nvidia's valuation also got a significant boost thanks to comments made in a presentation by CEO Jensen Huang. Speaking at the Communacopia and Technology Conference hosted by Goldman Sachs, Huang stated that his company was continuing to see incredible levels of demand.

He also issued encouraging guidance for Blackwell, the company's next-generation processors. Huang said that Blackwell's manufacturing has already ramped up, the chips are set to begin shipping to customers in significant numbers in Q4, and demand among customers is very high.

The Nvidia CEO also said that his company was approaching its designs with fabrication versatility in mind. The company currently relies on Taiwan Semiconductor Manufacturing to manufacture its chip designs, but it says it's taking steps to ensure it can move to other fabs if necessary.
