Over the past year, I've consistently argued that Tesla (NASDAQ: TSLA) should now be viewed as an artificial intelligence stock, rather than a traditional electric vehicle stock. First, Tesla has struggled with auto sales in recent years, yet its market cap continued to soar. If you needed even more proof that Tesla is being valued as an AI stock, not an EV stock, all you need to do is review the company's recent quarterly earnings announcement. And yet there's another EV maker attempting to pivot toward AI, and it still has a market cap of just $23 billion. This Tesla competitor could be the next big AI stockEarlier this year, I named Rivian Automotive (NASDAQ: RIVN) my top growth stock for 2026.
