- The total market cap of the top 20 companies is $2.22 trillion
- Apple makes up 23.6% of that
- Apple is worth more than Google and Microsoft combined. You could even add Cisco on top of that, and it still wouldn’t be enough.
N.B. Facebook isn’t on this list as it is not yet included in the list of technology companies on Google Finance. Facebook’s current market cap is $61.66 billion, which would put it in 12th position.
