Billionaire break-ups are seemingly becoming a trend in recent years, with Jeff Bezos and MacKenzie Scott divorcing in 2019 and Bill Gates and Melinda French Gates following in their footsteps in 2021. While their ex-hubbies continue their race to become the world’s richest person, MacKenzie Scott and Melinda French Gates devote their time to giving away billions of dollars. Let’s take a closer look at how these equally powerful and wealthy women are stepping up to support individuals and organisations in need – and the ex-wives that went before them. 1. MacKenzie Scott American novelist and billionaire philanthropist MacKenzie Scott parted ways with Amazon founder and executive chairman Jeff Bezos in 2019 after 25 years of marriage. After their divorce, she received a 4 per cent stake in Amazon, which was then valued at US$35 billion. Since then, Scott has already unloaded more than US$8.5 billion to hundreds of organisations focused on gender equality, racial justice, public health and other causes, per CNN . 6 facts about A$AP Rocky, father to Rihanna’s first child Scott continues to make waves for her enormous and fast-paced donations in 2022, staying true to her widely quoted promise to hand out her fortune “until the safe is empty”.

Melinda French Gates The latest to join this high-profile divorcee list, Melinda French Gates was hitched to Microsoft co-founder Bill Gates from 1994 to 2021 . The former computer scientist and general manager at Microsoft recently made headlines for deciding not to give the bulk of her US$11.4 billion fortune to the Bill & Melinda Gates Foundation. Through her investment company Pivotal Ventures, French Gates actually joined forces with Scott in 2021 to bestow US$40 million to four organizations that promote gender equality, according to CNBC . 5 things to know about Thai billionaire Nualphan Lamsam 3.

Her 26-year-old marriage to oil baron and Continental Resources chairman Harold Hamm ended in 2015, with a handwritten cheque of nearly US$1 billion.

So, I take this privilege of wealth with a great deal of gratitude and humility, and will attempt to use it to buy freedom from those shackled by poverty, neglect or the cruel fate of circumstance,” she wrote in her Giving Pledge letter.
