Nvidia said it is planning to build AI servers worth as much as $500 billion in the U.S. over the next four years with help from partners such as TSMC, the latest American tech firm to back the Trump administration's push for local manufacturing. Monday's announcement includes production of its Blackwell AI chips at TSMC's factory at Phoenix, Arizona and supercomputer manufacturing plants in Texas by Foxconn and Wistron that are expected to ramp up in 12 to 15 months.
