Warren Buffett
Warren Buffett's company has a stake in Chinese EV maker BYD.
  • Warren Buffett could have invested in Tesla when it was worth almost nothing, Elon Musk said.
  • Buffett passed on Tesla at a $200 million valuation in 2008, Musk previously said.
  • Tesla is now worth about $700 billion, but that's down from a peak valuation of $1.2 trillion.

Warren Buffett missed a trick when he passed on Tesla early on, Elon Musk said.

"He could've invested in Tesla when we were worth basically nothing and didn't," the Tesla and SpaceX CEO posted on X, the website formerly called Twitter, on Thursday.
