What minimum net worth did Forbes require for its 2018 Forbes 400 list?

Forbes required a minimum net worth of $2.1 billion for its 2018 Forbes 400 list.

That threshold was the highest ever recorded for the American wealth ranking at the time. Forbes’ annual Forbes 400 list evaluates the fortunes of the 400 wealthiest people in the United States, using estimates of assets, company ownership, property, investments, and debt.

Jeff Bezos topped the 2018 edition with an estimated fortune of $160 billion, while Bill Gates and Warren Buffett followed him. The entry threshold rose as stock markets, private-company valuations, and large technology fortunes increased.

The threshold should not be confused with the $1 billion benchmark used for Forbes’ global World’s Billionaires list. A person can qualify as a global billionaire but still fall below the much higher cutoff required to enter the Forbes 400.
