Elon Musk Blinks? Tesla’s Terafab May Reportedly Lean on TSMC After All
Tesla (TSLA) CEO Elon Musk may let TSMC (TSM) take a larger role in its Terafab chip project, according to Digitimes. Negotiations are set to reopen, with TSMC potentially handling construction and operations. Musk initially planned Tesla and SpaceX to lead the project. TSLA shares closed at $399.81 on Friday, up 0.10% in extended trading.
