Vietnamese electric vehicle start-up VinFast’s valuation has overtaken those of Detroit’s “big three” carmakers after shares of the lossmaking company soared on their first trading day.

VinFast closed at $37.06 in New York on Tuesday, well above the $10 price agreed upon when the carmaker merged with a special purpose acquisition company to secure a stock market listing. Its market capitalisation topped $85bn, at least $27bn higher than either Ford, General Motors or Fiat Chrysler owner Stellantis.

VinFast’s billionaire founder Pham Nhat Vuong owns about 99 per cent of its shares, leaving only a small amount available for trading. Only 1.3mn shares of the Spac were able to be traded after earlier redemptions and just $185mn in shares changed hands, according to analysts.
