U.S. stock futures extended their upward momentum on Wednesday, with S&P 500 and Nasdaq futures reaching fresh record levels as Nvidia surged in premarket trading. The chipmaker jumped 1.9% after a Reuters report indicated that the U.S. government has approved around 10 Chinese firms to purchase Nvidia’s H200 artificial intelligence chip, boosting optimism around demand prospects.
Live News
S&P 500 and Nasdaq futures rose to new intraday highs in early trading on May 14, 2026, driven by a rally in semiconductor and technology stocks. Nvidia was the standout gainer, climbing 1.9% in premarket activity and lifting the company’s market valuation to approximately $5.9 trillion.
The move came after Reuters reported, citing sources familiar with the matter, that the U.S. government has cleared about 10 Chinese companies to buy Nvidia’s H200 processor—the company’s second-most powerful AI chip. The approval suggests a measured easing in trade tensions between the world’s two largest economies, at least within the sensitive semiconductor sector.
The H200 chip is a high-bandwidth memory accelerator designed for large-scale AI training and inference workloads. News of the clearance triggered a broad rally in AI-related stocks, with other chipmakers such as AMD and Broadcom also posting modest gains in premarket trading.
Traders are now watching for potential spillover effects into the broader market. The S&P 500 and Nasdaq have been on an upward trajectory in recent weeks, supported by strong corporate earnings and resilient economic data. The latest development around Nvidia adds fresh fuel to the rally, though analysts caution that geopolitical uncertainties remain a key risk.

Expert Insights
The latest development around Nvidia’s H200 chip clearance introduces a cautiously optimistic narrative for the semiconductor industry, particularly for companies with significant exposure to the Chinese market. While the approval covers only a limited number of firms, it may signal a willingness from U.S. regulators to permit certain high-value transactions under strict oversight.
For investors, the move underscores the enduring demand for AI infrastructure. Nvidia’s H200 chip is a key product in the company’s data center lineup, and any expansion of its addressable market—especially in China—could support long-term revenue growth. However, the approval process remains opaque, and the political environment could shift quickly.
From a sector perspective, the renewed appetite for AI-related equities suggests that the current rally is not solely driven by sentiment but also by tangible policy developments. Yet it is essential to recognize that the clearance is not a blanket waiver; only about 10 firms are involved, and the U.S. retains the right to revoke or modify licenses.
Traders and portfolio managers may view this as a tactical positive for Nvidia and its peers, but broader exposure to Chinese demand dynamics remains a double-edged sword. Any escalation in trade rhetoric or new restrictions could quickly reverse gains. As such, a measured approach—focusing on companies with diversified revenue streams and strong domestic demand—may be prudent for those looking to navigate the current environment.
