Intel''s self-driving unit Mobileye files for U.S. IPO Intel did not reveal how much stake it will retain in the unit when it goes public, but the chip giant has previously said it will retain a majority stake. The filing comes when investor interest in IPOs has waned significantly due to recent stock market volatility fueled by aggressive rate hikes by global central banks and geopolitical tensions. The move to list Mobileye is part of Intel''s broader strategy under Chief Executive Officer Pat Gelsinger to turn around its core business.
