Shares of Intel climbed as much as 4.65% in overnight trading. The stock closed 7.4% higher in regular trading, giving the company a market value of about $104.4 billion.

The Trump administration is in talks with Intel Corp. to have the US government take a stake in the beleaguered chipmaker, according to people familiar with the plan, in the latest sign of the White House’s willingness to blur the lines between state and industry.

A deal would help shore up Intel’s planned factory hub in Ohio, said the people, who asked not to be identified because the deliberations are private. The company had once promised to turn that site into the world’s largest chipmaking facility, though it’s been repeatedly delayed. The size of the potential stake isn’t clear.
