Mark Zuckerberg’s net worth has spiked by $5 billion in the first weeks of 2017—a bigger jump than anyone else on Forbes’ billionaires list, Forbes reports.

As of Friday, the Facebook founder had seen his net worth increase to approximately $53.8 billion, locking him in as the world’s fifth-richest person, Forbes said. Facebook shares climbed 11.5% between Jan. 3 and Jan. 13, and Zuckerberg owns approximately 410 million company shares.

Zuckerberg made Forbes’ top 5 for the first time last year.

Shares in Facebook outpaced the NASDAQ — the exchange on which it trades — which was up 4% during this period. Investment bank Oppenheimer recently named the stock its top 2017 internet pick and reiterated its “outperform” rating and $144 price target. Analyst Jason Helfstein cited the performance of shopping ads during the holidays, increased usage ahead of the election, and accelerated innovation in Facebook-owned Instagram.

Facebook also recently launched a new “journalism project” aimed at increasing news literacy on its website.
