15 Richest Americans in Sports: Forbes

Forbes' Real-Time Billionaires ranking tracks the daily ups and downs of the world's wealthiest people. ThinkAdvisor took a look at the richest American men and women on the list with investments in sports. The wealth-tracking platform provides ongoing updates on the net worth and ranking of each individual confirmed by Forbes to be a billionaire. The value of individuals' public holdings are updated every 5 minutes when respective stock markets are open. Individuals whose fortunes are significantly tied to private companies have their net worths updated once a day. In cases where an individual owns a stake in a private company that accounts for 20% or more of his or her net worth, the value of the company is adjusted according to an industry- or region-specific market index provided by FactSet Research Systems when available.
