CNBC's Jim Cramer on Wednesday broke down the reasons Rivian Automotive was able to soar in its market debut, despite the fact many other growth-oriented stocks were sold because of inflation fears.

After rising 29% to close at $100.73 per share, Rivian's market cap of $85.9 billion is bigger than Ford's $77.4 billion, and it's just shy of General Motor's $86.05 billion. However, the "Mad Money" host contended that comparing Rivian to legacy Detroit automakers may be misguided all together.
