Real Time Billionaires

Forbes’ Real-Time Billionaires rankings tracks the daily ups and downs of the world’s richest people. The wealth-tracking platform provides ongoing updates on the net worth and ranking of each individual confirmed by Forbes to be a billionaire.

The location could move or need to be replaced. If replacement is needed then the most respected freely available such replacement that can be found might be the sensible choice but depending on circumstances (e.g. how much cost involved and how much more respected) a more respected but less freely available source might be chosen instead.

Historical note

At time of creating claim 19 June 2023. Jeff Bezos was 4th with $148.2bn and Elon Musk 1st with $236.9bn
