Polis added at least $6 million to his fortune last year to arrive at a minimum net worth of $72.09 million.
One of the congressman's largest assets remains a blind trust that he created in 2010 that is worth $25 million to $50 million.
In addition to a diverse portfolio of stocks and funds, Polis reported having an array of real estate investments, including properties in Boulder, Colo., Denver and Florida, and sizable stakes in businesses including LifePics, a photo storing, sharing and printing service, and Symbius Medical, a home medical equipment supplier.
