Mark Zuckerberg’s wealth took a staggering hit, plunging by approximately $31 billion in one of the largest single-day wealth declines ever recorded. This dramatic setback followed Meta Platforms Inc.’s fourth-quarter financial results, which failed to meet analysts’ expectations.

Meta, the parent company of Facebook, is currently grappling with a historic stock price collapse triggered by disappointing quarterly results. The company revealed that its monthly Facebook user base had not grown in the last quarter, raising concerns about its future growth prospects. As a result, Meta’s stock plummeted by a substantial 24% during trading on Thursday, shaking investor confidence.

This precipitous decline in Meta’s stock price has had a profound impact on Mark Zuckerberg, Meta’s CEO, and co-founder. His net worth has dwindled from a staggering $120.6 billion at the close of the market on Wednesday to approximately $92 billion, a substantial drop. This significant loss in wealth has pushed Zuckerberg out of the list of the world’s top ten wealthiest individuals for the first time since July 2015.

Zuckerberg’s wealth erosion of $31 billion in a single day ranks as one of the most substantial declines in wealth ever attributed to a drop in share prices. It is only surpassed by the highly volatile fluctuations in Elon Musk’s fortune. For instance, Musk, the world’s richest person, experienced a one-day loss of $35 billion in November when Tesla Inc.’s shares fell following a Twitter poll in which he sought public opinion on whether to sell 10% of his stake in the company. Musk’s net worth also took a hit of $25.8 billion just last week.

In addition to Mark Zuckerberg, Meta’s other co-founders are also grappling with unprecedented losses in their personal fortunes. Dustin Moskovitz, the world’s 79th-richest individual with a net worth of $21.2 billion as of Wednesday, saw his wealth decrease by approximately $3 billion. Meanwhile, Eduardo Saverin, whose net worth was estimated at $17.5 billion, witnessed a drop of over $4 billion in his fortune.

Sheryl Sandberg, Meta’s Chief Operating Officer, experienced a decline in her personal wealth, with her $2.5 billion fortune shrinking by over $100 million. However, Sandberg’s wealth is less tied to Meta’s shares compared to Zuckerberg’s, which provides some cushion against the financial blow.

Meta’s disappointing earnings results have compounded the company’s challenges. In addition to its struggling stock price, Meta is currently embroiled in several regulatory battles and is seeking to justify its strategic shift toward the metaverse, an immersive internet concept. Meanwhile, rival platforms such as TikTok and YouTube are gaining popularity among younger users, intensifying competition in the social media landscape.

In summary, Mark Zuckerberg’s immense wealth has taken a massive hit of $31 billion due to Meta’s underwhelming quarterly results, marking one of the largest single-day wealth declines in history. This setback, coupled with ongoing regulatory challenges and increased competition from other platforms, poses significant hurdles for Meta’s future growth and success.
