Nvidia was gaining after key partner Taiwan Semiconductor Manufacturing gave an upbeat outlook on artificial-intelligence processor demand.

Nvidia said it has filed applications to resume selling H20 GPUs in China and has received assurances that licenses will be granted.

Currently, Nvidia accounts for nearly 8 percent of the S&P 500. That’s the highest weighting for a single stock in 45 years, according to Todd Sohn, senior ETF strategist at Strategas Securities. For context, industrials account for 8.7 percent of the index, while healthcare stands at 9.1 percent.

President Donald Trump’s administration has barred Nvidia Corp. from selling its H20 chip in China, an escalation of Washington’s tech battle with Beijing that will cost the company billions of dollars and hamstring a product line it explicitly designed to comply with previous US curbs.
