Mark Zuckerberg’s net worth drops £15 billion in just months

For Facebook CEO Mark Zuckerberg, 2018 was a year filled with scrutiny, criticism and scandals.

Zuckerberg, whose company went public shortly after his 28th birthday, is one of the richest and most successful college dropouts of all time. But in April 2018, the billionaire had to testify in front of Congress after it was disclosed that political data firm Cambridge Analytica had gained access to the private information of up to 87 million Facebook users. And Facebook's latest scandal prompted the social media giant to expose its impropriety itself: The company said it gave streaming services like Spotify and Netflix the ability to read its users' private messages.

Tech magazine Wired pegs Facebook's total scandals for the year to number more than 20. But have the repeated scandals affected Facebook's net worth — and the net worth of one of the world's richest billionaires?

Mark Zuckerberg Net Worth: £40 Billion

Forbes named Mark Zuckerberg the richest U.S. entrepreneur under age 40 in 2017. At that time, Zuckerberg's net worth was £56 billion — £45 billion more than the runner-up, Facebook co-founder Dustin Moskovitz. Zuckerberg's net worth jumped to £57.1 billion in late April 2018, following his appearance in Congress, after hitting £49 billion in late March after the disclosure of the Facebook privacy controversy, according to Bloomberg data.

However, the onslaught of data and ethical revelations seem to have finally taken their toll: As of Dec. 26, 2018, Zuckerberg's net worth is about £39.5 billion.

Zuckerberg holds the titles of co-founder, chairman and CEO of Facebook. Facebook boasts the fourth-largest initial public offeringin U.S. history. The company's shares were priced at £30 each, valuing Facebook at £82 billion. Zuckerberg owned more than 503 million shares and options when the company went public, which boosted his share of the company to more than £13 billion, Forbes reported.

In 2016, Zuckerberg began to sell some of his Facebook stock. As of April 2017, Zuckerberg owned 462.3 million shares, Money reported. FB stock is worth more than £106 as of Dec. 26, 2018. The company experienced a nearly 25 percent drop in Facebook stock price in July 2018, stemming from the controversies.

Facebook Privacy Controversy

In March 2018, several media outlets, including The New York Times and The Guardian, reported that Cambridge Analytica, a data analysis firm that worked on President Donald Trump's 2016 campaign, obtained the data of 50 million Facebook users and secretly kept it. In early April, Facebook disclosed in a blog post that it believes the private data shared with Cambridge Analytica actually could have affected up to 87 million users.

In the blog post, Mike Schroepfer, chief technology officer at Facebook, outlined nine ways the company was working to better protect user information, including limiting the types of information that can be accessed by third-party apps. Despite the reassurances, Facebook stock plummeted nearly 10 percent. In early April, Zuckerberg testified in front of Congress about his company's mishandling of the personal data. His two-day apology tour ended up being a valuable appearance — it led Facebook stock to rise about 3 percent.
