  • Vietnamese electric carmaker VinFast has seen its shares skyrocket since it went public on August 15.
  • Its market capitalization now stands at over $190 billion – but some investors cannot hide their disbelief. 
  • Veteran short-seller Jim Chanos called the carmaker a "$200B meme-stock" in a post on X.

Vietnamese carmaker VinFast's shares have staged a sizzling rally since the company's US stock-market debut two weeks ago.

Monday's close saw the market capitalization of the lossmaking EV firm hit an eye-watering $190 billion – more than Ford, General Motors, and Chrysler Stellantis combined. 

VinFast shares closed at $82.35, meaning the stock has soared over 680% since it went public on August 15 via a special-purchase acquisition company, or Spac.
