<h1>Semiconductor firm nears $5 trillion valuation amid AI chip boom, big orders, supercomputers and geopolitical export risks</h1> A semiconductor company is set to reach a USD 5 trillion market valuation following rapid share gains driven by demand for AI chips. Regulators and international financial authorities have warned of a potential technology asset bubble. The company disclosed substantial chip orders and is partnering with a federal energy agency to build multiple AI supercomputers, and announced a multibillion-dollar investment in an AI developer to expand data-centre capacity. It has also discussed designing a chip for China with the U.S. administration, a matter reportedly to be raised in upcoming high-level U.S.-China talks, implicating export, investment and national-security review risks.
