$86.5 billion This achievement easily tops the previous record high of $76.1 billion for shares of Ford in 1999, according to data from the Center for Research in Security Prices. The high watermark for GM stock was more recent, when it reached a market value of $67.7 billion in October 2017. Today both of those stocks have lost a good chunk of their value. GM (GM), valued at $50.7 billion, and Ford (F), worth $36.9 billion, together are worth only about 1% more than Tesla alone.
