Two new members of the $4 trillion club

The $4 trillion club had two new entries at the end of October 2025 as Microsoft and Apple joined Nvidia in reaching the milestone. Apple was the first company to hit a $1 trillion valuation in August 2018, nearly 500 years after the first formal stock market began trading in Amsterdam in 1602. It took less than seven years for Nvidia to reach a market cap four times that level in July 2025 and just a few short months for two other companies to achieve that distinction. Nvidia itself subsequently hit $5 trillion as investors show limited sign of diminished enthusiasm for the AI theme.
