Rivian Automotive Inc. (Nasdaq: RIVN US) reached a market value of over $100 billion two days after its initial public offering, drawing comparisons to Tesla Inc. But there are stark differences: When Tesla went public in 2010, the Elon Musk-led firm disclosed $93 million in revenue and losses far below the $1 billion Rivian reported for the first half. What’s more, Tesla’s initial market capitalization was about $2 billion and didn’t reach $90 billion until 2020.
