Jeff Bezos and his wife, MacKenzie, may be the first billionaire couple with a huge stake in an enormous technology company to announce their divorce.

They won’t be the last.

The surprise announcement last week that the Bezoses would divorce after 25 years of marriage instantly raised questions about the future of their 16 percent, roughly $140 billion stake in Amazon. As its founder, chairman, chief executive and largest shareholder, Mr. Bezos exerts almost complete control over the company he created.

The big question is, now what? Will Ms. Bezos sell her portion of the family’s vast Amazon holdings? Will she seek a seat on the company’s board? Will she push for big strategic or management changes?

The Bezos divorce could have consequences for investors in other companies with billionaire founders — Google, Facebook, Groupon and Snap, to name a few. Unlike Mr. Bezos, who owns Amazon shares with ordinary voting rights, these tech entrepreneurs wield control of their companies by holding special classes of shares that confer extra power to their owners.
