Elon Musk is set to make a virtual appearance at a technology event hosted by semiconductor equipment leader ASML on Thursday, where he is expected to discuss Terafab, his proposed large-scale semiconductor manufacturing project designed to supply chips for Tesla (NASDAQ:TSLA) and SpaceX (NASDAQ:SPCX). The appearance comes as investors await the pricing of SpaceX’s initial public offering, which is expected later on Thursday and could become the largest IPO ever completed.
