The first trillionaire would be Microsoft co-founder Bill Gates. 

That’s according to research by Oxfam, an international network of organizations collectively working to alleviate global poverty. Its recently published report finds that eight billionaires from around the globe have as much money as the 3.6 billion people who make up the poorest half of the world’s population.

 These 8 billionaires own same wealth as half the world’s poorest

When Gates left Microsoft in 2006, his net worth was $50 billion, according to Oxfam. By 2016, his wealth had increased to $75 billion, “despite his commendable attempts to give it away through his Foundation,” the report says.
