Mark Zuckerberg’s fortune jumped by $12.5 billion on Thursday, the largest one-day increase in his wealth, after he vowed 2023 will be the “year of efficiency” for his social-media giant, Meta Platforms Inc.
The 38-year-old chief executive is rebounding from his worst year on record, with his wealth tumbling from a peak of $142 billion in September 2021. He had a number of daily ups and downs in 2022: he lost as much as $31 billion in a day last February, then gained $11 billion in April, only to lose $11 billion in October after another disappointing earnings report.
