Facebook‘s stock shot up from $21.08 a share on the first day of trading in November to $28 a share at the end of the day Friday, its highest price since July. Zuckerberg, who owns about 504 million shares of Facebook stock, gained about $3.48 billion as a result!
When Facebook first went public at $38 a share in May, Zuckerberg’s shares were worth $19.1 billion. In the following months, the stock dropped to less than half that IPO price to $17.55 in late August, pushing Zuckerberg’s net worth down to $8.84 billion.
As of Friday, Zuckerberg’s net worth was $14.1 billion and will likely only continue to grow in December.
