What does Nvidia’s $6 trillion milestone mean?
Reports said Nvidia was nearing a $6 trillion market value as its shares rose. “Nearing” is an approximate, time-sensitive description: the available coverage does not verify an exact closing market capitalization, so it should not be read as confirmation that Nvidia reached $6 trillion.
