Forbes estimated that Don Jr.’s net worth had jumped from about $50 million to about $300 million since the 2024 election:

Here’s How Much Donald Trump Jr. Is Worth

Will Forbe's, or author of the piece Kyle Khan-Mullins, estimate his net worth to be greater than $700 million by the end of Trump 2.0?

Since estimates come infrequently, the closest estimate to 2029-01-20 will be used so long as it is within a year. If there is no estimate from Forbes or Kyle Khan-Mullins in that time period then there is some uncertainty in the market and I may NA but if many estimates align on either side of $700 million then I'll resolve using these.
