Not sure if this is legit or not, but according to that site:

Top 1: 151,497 BTC ($93,074,379 USD)
Top 10: 53,019 BTC ($32,572,739 USD)
Top 100: 10,000 BTC ($6,143,629 USD)

Top 10,000: 106.80 BTC ($65,611 USD)

Unfortunately, it seems to end at page 100. And the private keys to many of these addresses could be lost or owned by Satoshi. It might be possible to calculate the balance required to get into the top 100,000 by using the table at the top of the page but the maths to do so would be pretty complicated.

EDIT: Forgot to mention that it is possible that a single person could own multiple addresses. And a single address can also house the funds of multiple people (e.g. an exchange's address).
