I imagine she got close to 50% of the total assets, with him gaining the control of the companies. she was with him from the start of amazon and one of its first employees. If she had wanted the company, she'd have had the leverage to keep half of their interest in it.
A rare high profile divorce that seems to have been settled amicably. Don't see those too often nowadays.
I know very little of the marriage. Did Bezos cheat? Was it just a mutual thing where they decided to no longer go on with the marriage?
Tabloid rumors of him having an affair. Not much else. But they both presented their divorce publicly and together.... and now seem to have split and finalized it publicly and together. Maybe they're just putting on a front to keep it good for business.. or maybe they really did just drift apart.. still much better than most divorces nowadays.
I'm willing to wager they were separated and tabloids saw him with his new partner, and assumed it was an affair. There's a whole thing about him calling out the national enquirer's owner for threatening to extort him. https://www.vox.com/technology/2019/2/7/18216281/jeff-bezos-medium-national-enquirer-ami-pecker-release-dick-pic
