Internet reports that the U.S. government's investment bet on Intel is reaping huge returns after Nvidia's unexpected investment triggered Intel's share price to the largest increase in nearly four decades. Less than a month ago, Trump brokered a deal under which the U.S. government would acquire about 10% of Intel. The surge in Intel's share price on Thursday sent its share price climbing to $31.79, raising the market value of the U.S. government's stake to about $14 billion-a floating paper profit of $4.9 billion when the agreement was reached in August. Nvidia's investment is Intel's latest "life-saving money". For years, Intel has been in deep trouble: on the one hand, its manufacturing business is plagued by difficulties, and on the other hand, chips used in artificial intelligence (AI) have become a core growth area of the semiconductor industry (where Intel lags behind).
