US blocks global use of Huawei AI chips in an unprecedented move announced Tuesday. The Bureau of Industry and Security (BIS) issued new guidelines restricting anyone worldwide from using Huawei’s Ascend chips without a license, deeming such use a violation of US export control rules. The impact on tech markets was immediately felt, and right now, Nvidia stock has jumped over 5% following the announcement. This kind of action against Huawei’s AI chips has also created some significant ripples throughout the entire tech sector.

US Blocks Huawei AI Chips: How Market Volatility and Nvidia Stock Impact Tech Investments

Export Controls Tighten Despite Tariff Truce

The US blocks Huawei AI chips despite Washington and Beijing recently announcing a 90-day tariff reduction deal. The BIS stated that Huawei’s development of Ascend chips is “likely” violating US export controls, and users could face “substantial criminal and administrative penalties,” such as imprisonment, fines, and other restrictions.

Nvidia CEO Jensen Huang stated:

“The ecosystem of artificial intelligence will build on top of our standard versus somebody else’s standard. If we don’t serve a particular market, leave a market altogether, there is no question somebody else will step in.”

Nvidia Benefits Amid Market Volatility

Nvidia stock experienced significant growth after the US blocking Huawei AI chips announcement. The company’s shares have, at the time of writing, rebounded about 28% from early April lows, which shows a remarkable resilience amid all of the market volatility and uncertainty that investors are facing.

Wall Street projects an impressive 54% revenue growth for Nvidia in FY 2026, positioning it for potential market dominance. The timing of these restrictions on Huawei AI chips couldn’t be better for Nvidia, as Jensen Huang has also just announced a major deal to supply 18,000 of their Blackwell chips to Saudi AI company Humain.

Emerging Challenges for Nvidia

Despite positive market reaction to restrictions on Huawei AI chips, some analysts remain cautious about Nvidia’s future prospects. Seaport Research Partners’ Jay Goldberg initiated a sell rating with a $100 price target in late April, which represents the first Wall Street sell rating for the company.

Goldberg explained:

“The bull case was fully priced in, with numerous downside catalysts waiting in the wings.”

Nvidia’s gross profit margins reveal mounting competitive pressure. The company reported a 78.4% GAAP gross margin one year ago, but this figure has declined every quarter since then, and the Q1 2026 estimates are at approximately 70.6%, which is concerning for some investors.

Chiu Shih-fang, a senior tech supply chain analyst with the Taiwan Institute of Economic Research (TIER), said:

“To ensure the US’ own strategic advantage, it is expected that Washington’s trade talks with other countries will also focus on technology controls on China, as well as crack down on laundering of country of origin for exports.”

As Nvidia approaches its May 28 earnings report, investors will closely monitor how these US blocks on Huawei AI chips might affect the company’s strategy and growth potential in an increasingly complex and competitive landscape.
