The world is likely to see its first trillionaire in 20 years, and they are likely to have made their fortune in the space industry according to one analyst.
In its 2013 Global Wealth Report, Credit Suisse said that two generations from now "future extrapolation of current wealth growth rates yields almost a billion millionaires, equivalent to 20 per cent of the total adult population.
"If this scenario unfolds, then billionaires will be commonplace, and there is likely to be a few trillionaires too - eleven according to our best estimate."
Earlier this week, Forbes released their 2015 Billionaires list which revealed there is now a record 1826 billionaires worldwide with an aggregate net worth of US$7.05 trillion (NZ$9.27 trillion), up from US$6.4 trillion (NZ$8.4 trillion) a year ago.
The richest person on the list is Microsoft co-founder Bill Gates, with an estimate fortune of $79 billion - still a long way from the $1000 billion needed to reach trillionaire status.
