Micron, Intel, and AMD recorded combined market-capitalization increases of roughly $2 trillion in the second quarter, with Micron adding about $920 billion, quadrupling revenue, and rising more than 240 percent. The three companies now rank as the 10th, 11th, and 12th most valuable U.S. tech firms. A claim that chipmaker shares rose sharply in the first half of 2026 is disputed by available data.
